DESCRIPTION OF THE INVENTION (1) TECHNICAL FIELD The present invention relates to an image display device, and more particularly to a single-plate projection image display device that can perform color display without using a color filter and using an image display panel. The present invention is applicable to a small-sized projection-type color liquid crystal television system and an information display system. BACKGROUND ART The following describes a conventional projection-type image display device using a liquid crystal display panel. Such a projection-type image display device is based on the liquid crystal display panel itself. It does not emit light, so it is necessary to design a separate light source, but compared with a projection type image display device using a CRT, it has extremely excellent characteristics such as wide color reproduction range, small size, light weight, and no need for convergence adjustment. To use a liquid crystal display panel When a full-color head TF is used in a projection-type image display device, there are a three-plate type using two liquid crystal display panels and a single-plate type using only one in response to the two primary colors. The three-plate projection image display device uses white light separately. Optical system divided into three primary colors of red (R), green (G) and blue (B), and r Three liquid crystal display panels of 〇 and b colors are respectively modulated to form an image, and the respective images of R, G, and B colors are optically overlapped to achieve full color display. Three-plate projection image display Although the device can effectively use the light emitted from the white light source, 'because the optical system is complicated and the number of components is large, it is inferior to the single-plate projection image display device from the viewpoint of cost and size. The image display device uses a piece with a mosaic arrangement -4- This paper is applicable in g @ 家 standard (CNS) A4 specification (21Qχ297 public publication Qiao-a 1227338 A7 ____________________ 5. Description of the invention (2) The liquid crystal display panel of the second primary color filter. Therefore, the full-color image displayed by the liquid crystal display panel is projected on a projection surface such as a curtain by a projection optical system. This single-plate projection image display device As disclosed in Japanese Patent Application Laid-Open No. 59-230383, when a single-plate type is used, the structure of the optical system is simpler than that of a three-plate type because a single liquid crystal display panel is used, which is suitable for low-cost applications. This is a compact projection-type image display device. However, when using the single-plate type with color filters, the color filter absorbs light, so that the brightness of the image is reduced by about 1/3 compared with the three-plate type using the same light source. In addition, because the two pixel areas corresponding to r, 0, and b of the liquid crystal display panel need to form a group to display one pixel, the resolution of the image is also reduced to w 3 of the three-plate resolution. The brightness of the light source is a method to reduce the brightness, but when it is used in people's livelihood, it is often unwilling to use a light source that consumes a lot of power. In addition, when using an absorption-type color filter, the light energy absorbed by the color filter is used Turning into heat will increase the brightness of the light source in vain, which will not only cause the temperature of the LCD panel to rise, but also accelerate the fading of the color calender. Therefore, how to effectively use the light provided is an important issue in increasing the utilization cost of a projection type image display device. In order to improve the brightness of a single-plate projection type image display device, a liquid crystal display device having a full-color display without a color filter has been developed (Japanese Patent Application Laid-Open No. 4-6053 8). This liquid crystal display device uses a dielectric reflector, such as a dichroic mirror, to divide the white light emitted from the light source into three light beams of R, G, and b, and makes it enter a micro lens array arranged at the light source end of the liquid crystal display panel at different angles. Each light beam that enters the micro lens is transmitted through the micro lens. -5- This paper size is in accordance with the Chinese National Standard (CNS) A4 specification (210 X 297 mm) I227338 A7 ^ 一 —___ B7 V. Explanation h) '~ — ——- Mirror, according to the incident angle, condenses light in the corresponding pixel area. Therefore, the separated R, G, and B light beams are modulated in each pixel region for full-color display TJT. JP-A-5-2493 No. 18 discloses a method of using light beams corresponding to r, g, and B rays. A transmissive holographic element is used in place of the above-mentioned dielectric mirror to improve the light utilization ratio. In addition, Japanese Unexamined Patent Publication No. 222361 discloses a transmission holographic element having a periodic structure corresponding to a pixel gap. Device that provides dielectric mirror and micro lens functions. The single board is another issue of resolution. By adopting the field sequential system, the same resolution as that of the three-plate type can be obtained on a liquid crystal display panel. The field sequence system is to switch the color of the light source at a speed that cannot be separated by human vision. The image colors are mixed by the additive method (& additive additive method) using time-sharing display of each image color. A projection-type image display device that performs full-color display in a field sequential system has a structure as shown in Fig. 76. The display device cooperates with the vertical scanning period of the liquid crystal display panel to rotate the disc composed of R, G, and B color filters at high speed, and sequentially input image signals corresponding to the colors of the color filters into the liquid crystal. Driving circuit of the display panel. The human eye can recognize a composite image of images of various colors. When such a field sequential display device is used, unlike the single-plate method, each pixel of the liquid crystal display panel displays r, G, and B images in a time-sharing manner, and thus its resolution reaches the same level as that of the three-plate type. _ Field display of other display devices, such as disclosed in IDW '99 (P989 ~ P992), each beam of R' G, B irradiates different areas of the liquid crystal display panel -6- This paper size applies Chinese National Standard (CNS ) A4 size (210X 297 mm) 1227338 A7 B7 V. Description of the invention (4) Projection type image display device. The display device separates the white light emitted from the light source into R, G, and B light beams by using a dielectric reflector, and then irradiates different regions of the liquid crystal display panel with each of the r, g, and B light beams. The irradiation positions of the r, G, and b light rays on the liquid crystal display panel are sequentially switched by rotating a three-dimensional prism. In addition, the projection type image display device disclosed in Japanese Patent Application Laid-Open No. 9-2 14997 uses the same J-crystal display device as the liquid crystal display device disclosed in Japanese Patent Application Laid-Open No. 4-60538 described above. White light is divided into light beams of different colors, and each light beam is made to enter the pixel area at different angles. Since the 泫 projection type image display device simultaneously takes into account the improvement of light use efficiency and high resolution, each frame image is divided into several sub-frame images in a time-sharing manner, synchronized with the vertical scanning period of the liquid crystal display tf panel, and the emission of the light beam is switched periodically.

In this patent, a projection type image display device that solves the above-mentioned problems is disclosed in Japanese Patent Application Laid-Open No. 9/214997. When the display device disclosed in Japanese Patent Application Laid-Open No. 9-214997 is used, the incident angle of the light beam to the liquid crystal panel and the period of the vertical scanning of the liquid crystal panel need to be sequentially switched in synchronization. Because the device performs such switching, a special IT room must be held between the liquid crystal display panel and the light source, and thus two sets of holographic elements and mirrors need to be driven. Since such a display device switches the angle of incident light, it requires several moving parts, making its control complicated. In addition, since each pixel of the liquid crystal display panel sequentially displays all colors, color adjustment cannot be performed with the liquid crystal display panel. In view of the foregoing, a main object of the present invention is to provide a projection-type image display device, which can achieve uniform and bright display with high resolution, and is suitable for miniaturization and low cost. DISCLOSURE OF THE INVENTION The projection type image display device of the present invention includes: a light source; an image display panel having a plurality of pixel regions capable of decaying each light; and a light control means for responding to a wavelength band to emit light from the light source.

圖76顯示先前之場序制投影型圖像顯示裝置。 施形態 本發明如在不使用彩色濾光器之單板式投影型圖像顯示 裝置中,自構成圖像之各幀圖像資料生成數個子幀圖像資 料,藉由圖像顯示面板使數個子幀圖像以分時顯示。繼 續,藉由使這些子幀圖像依序在被投影面上移動,以屬於 被圖像顯示面板之不同像素區域調變之不同波段的光線 (R,G,B光)依序照射被投影面上的同一區域,藉此達成 高解像度的全色彩顯示。 本發明著眼於被投影面上之相當於一個像素的特定區域 時,於某個子幀顯示期間(以下稱「子幀期間」),其特定 區域如被紅色光(R光)照射,則下一子幀期間被綠色光(G 光)照射,再下一子幀期間被藍色光(B光)照射。因而,採 用本發明時,被投影面上之各像素的顏色係藉由r,G及B 光的分時照射來定義。 ’ 在先前之場序制投影型彩色圖像顯示裝置與本發明之 間,有如下所述的顯著差異。 a 先前之場序制係以R,G及B光交互照射圖像顯示面板。 因此,在某一個子場(Subfield)期間,圖像顯示面板的整個 像素區域係被R,G及B光中的任何一種光線照射。因而, 被投影面上之各子幀圖像雖由r,G及B光中的其中一種顏 色像素構成,但因R圖像用子幀、_G圖像用子幀及B圖像^ 子幀係以人體視覺之時間分離能力以下的短暫時間二位做 分時顯示,所以眼睛藉由殘影看出彩色圖像。 &quot;&quot; -25-Fig. 76 shows a conventional field sequential projection type image display device. Embodiments In the present invention, for example, in a single-plate projection-type image display device that does not use a color filter, a plurality of sub-frame image data are generated from each frame of image data constituting an image, and a plurality of sub-frames are made by an image display panel. The frame image is displayed in time-sharing. Continuing, by sequentially moving these sub-frame images on the projected surface, light rays (R, G, B light) of different wavelength bands that are modulated by different pixel regions of the image display panel are sequentially illuminated and projected The same area on the surface to achieve high-resolution full-color display. When the present invention focuses on a specific area corresponding to one pixel on the projected surface, during a certain sub-frame display period (hereinafter referred to as a "sub-frame period"), if the specific area is illuminated by red light (R light), the next The sub-frame period is illuminated with green light (G light), and the next sub-frame period is illuminated with blue light (B light). Therefore, when the present invention is adopted, the color of each pixel on the projection surface is defined by the time division irradiation of r, G, and B light. There are significant differences between the conventional field sequential projection type color image display device and the present invention as described below. a The previous field sequential system used R, G, and B light to illuminate the image display panel alternately. Therefore, during a certain subfield, the entire pixel area of the image display panel is illuminated by any one of R, G, and B light. Therefore, although each sub-frame image on the projected surface is composed of one color pixel of r, G, and B light, the sub-frames for R image, sub-frame for _G image, and B-image ^ The time display is based on the short time below the time separation ability of human vision, so the eye can see the color image through the afterimage. &quot; &quot; -25-

Explanation of the invention (26) By appropriately setting the incident angles of the R, G, and B light, the micro lenses 7 are appropriately allocated to the pixel regions corresponding to each band. The focal distance of the micro lens 7 of this embodiment is designed to be 255 vm, and the angle formed by each beam is 5.8. . Specifically, the R light is incident on the liquid crystal display panel 8 vertically, and the B light and the G light are respectively 5.8 to the R light. Angle of injection. The dichroic mirrors 4, 5 and 6 have the spectral characteristics shown in Fig. 3, and selectively reflect green (G), red (R), and blue (B) light, respectively. The wavelength of g light is 520 to 580 nm. The wavelength of R light is 600 to 650 nm, and the wavelength of B light is 420 to 480 nm. Although the present embodiment uses the dichroic mirrors 4 to 6 and the micro lens array 7 to condense the three primary colors of light onto the corresponding pixel area, other optical means (such as those with the function of diffracting and splitting light) Transmissive holography). Because the above-mentioned liquid crystal display panel 8 is driven in a non-interlaced manner, an image of 60 frames is not displayed in one second, and the time (frame period) allocated to each frame is 1/6 seconds, that is, T = 1 / 60 (seconds) # 16.6 (milliseconds). In addition, in the case of interlaced driving, the scanning lines in the screen are divided into even-numbered lines and odd-numbered lines for interactive display, so D = 1/30 (seconds) and 33 · 3 (milliseconds) °. The time of even field and odd field (field time) of each frame is 1/60% = 16 · 6 (milliseconds). In this embodiment, information (data) of each frame image constituting an image is sequentially stored in a frame memory, and a plurality of sub-frame images are sequentially formed based on information selectively read from the frame memory. The method of forming a sub-frame image will be described in detail below. For example, an image (frame image) of a certain frame is an image shown in FIG. 4 (a). The frame image should be displayed in color. The color of each pixel is based on the definition of the above frame image. 29- Chinese National Standard (CNS) A4 specification (210 X 297 public love) 1227338 A7 B7 V. Information of the invention description (27) To decide. In addition, in the case of interlaced driving, an image of a certain φzhen can be obtained by the same processing as the "duck image" in this specification. The previous three-panel projection image display device is based on the above data, # data for R, G, and B light from each pixel, as shown in Figure 4 (b), (c), and (d) 户 # The data for the R image t frame, the G image duck, and the b image frame are generated. Continue to use the three image display panels for R, G, and B, which simultaneously display the R image frame, the G image frame, and the B image frame, respectively, and overlap on the projected surface. The model in FIG. 5 (a) shows a case where a specific pixel on the projection surface 13 is overlapped by the frames for r, 0 and B images. In the prior art, a single-plate projection image display device has a display panel in which R, G, and B image areas are set at different positions, respectively. Then, according to the data for R, G, and B, light # 1 is changed in the image area for r, G, and B to form a color image on the surface to be projected. At this time, because the R, G, and B lights are irradiated in a region smaller than the spatial separation ability of human vision, the R, G, and B lights are separated from each other in space, but they are seen by human eyes. Out is a pixel that is formed. The model in Figure 5 (b) shows that a specific pixel on the projection surface 13 is illuminated by R, 0, and B light. The pattern is different from the previous method, and the same area is sequentially illuminated by an imager area. The modulated R, G, and B light are on the same plane as the projected surface 1 3

Description of the invention (28) &quot; 一 ~ ^ ---- Again ^ · The point is very similar to the previous field sequence Big difference. Figure 5 (.) The model shows the situation in which a certain pixel of 13 feet is illuminated in a time-sharing mode with r, 0, and 6 lights in a frame and at the entrance of the moon gate. The screen shown in the left part of FIG. 5 (0) considers the three different sub-images of the block image display panel 8. As can be seen from Figs. 5 (a) to (c), in this embodiment, only one display panel can be used to achieve full-color display with the same high resolution and brightness as that of the two-plate type. / Refer to FIG. 6 for a detailed description of the sub-frame image. The construction. The left side of FIG. 6 shows the data of the R G and B image frames stored in the R, 0 and b frame memories. The right subdivision of FIG. 6 shows a display sub-frame 1 3. Benbei knows that the image showing the sub-frame i is displayed on the projected surface during the first three-thirds of the period (the first sub-frame period) '. Continue to display the image of display sub-frame 2 in the next period of 3 times (second sub-frame period), and display the image of display sub-frame 3 in the last period (third sub-frame period). The three sub-frame images in this embodiment are moved as shown in FIG. 7, and as a result of being separated in time and synthesized, the human eyes can see the original image shown in FIG. 4 (a). Next, the display sub-frame 1 is taken as an example to describe the material composition of the sub-frame image in detail. First, as shown in FIG. 6, the data for the first row of pixel regions in the display sub-frame are formed from the data about the first row of pixels (R1) stored in the R frame memory. The data for the second row of pixels in the display sub-frame 1 is formed by the relevant data of the second row of pixels (G2) memorized in the G frame. The data for the first column of the pixel area of the display sub-frame 1 is stored in the third memory of the B-frame memory. -31- This paper size applies the Chinese National Standard (CNS) A4 specification (21〇X 297 public copy) 1227338 A7 —_B7 _ 5. The description of the invention (29) is formed by the relevant data of the pixel (B3). The data for the pixel area of the fourth column of the display sub-frame 1 is formed by the related data of the four pixels (R4) of the younger brother in the body of R. In the following, the data of the display sub-frame 1 is constructed by the same procedure. The composition of the data of display subframes 2 and 3 is the same as that of display subframe 1. For example, the data for the pixel region of the 0th column of the display sub-frame 2 is formed by the data of the first column of pixels (B1) stored in the frame memory of the b for display, and the data for the first column of the pixel region of the sub-frame 2 is displayed. It is formed by the data related to the second row of pixels (R2) stored in the R frame memory, and displays the data for the second row of pixel regions in subframe 2. The third row of pixels (stored in the G frame memory ( G3) The related data is used to display the data for the third row of pixel regions of the display element 2 and is formed from the fourth row of pixels (B4) related data stored in the frame memory of B. In this way, by combining the data read from r, G, and b with their respective memories in a preset order, each data of the sub-frame displayed in a time-division manner is generated. As a result, although the data for each sub-frame includes all the color-related information of R, G, and B, R, G, and B each have only relevant information of a three-thirds area in the entire space. In more detail, the R information of the display sub-frame i can be seen from FIG. 6, which is only relevant information of the pixels that should form the first, fourth, seventh, tenth, and tenth columns of the frame image. The ruler information related to the pixels in the other columns of the frame image is allocated to the display sub-frames 2 and 3. In this embodiment, although the information of the same color is always displayed in each pixel region of the image display panel, the image can be synthesized by moving the image between the sub-frames and projecting. In addition, as can be seen from Figure 6, the image display: The total number of columns in the panel's pixel area is only greater than the number of pixels that make up a sub-frame image.

Description of the invention (30) The total number of columns is 2 more. These two columns function as the edge of the image movement. Next, a case where a plurality of moving sub-frame images are combined into one frame image will be described with reference to Figs. 8 and 9. First, refer to FIG. 8. Fig. 8 (a) shows a perspective view of a part of three sub-frame images projected on a projected surface such as a screen. The model is displayed sequentially from the left in the figure. The sub-frames 1 to 3 and the synthesized frame images are displayed. Fig. 8 (b) shows the corresponding pixel area of the pixel display panel, and the corresponding parts of the display sub-frames 1 to 3 are sequentially displayed from the left. The third column to the seventh column of the display subframe 1, the second column to the sixth column of the display subframe 2, and the first column to the fifth column of display subframe 3 are separated in time on the projection surface. Spatially overlap to form one frame image. As shown in FIG. 8 (b), although the positions of the pixel regions for r, g, and B on the image display panel are fixed, the operation of the image moving element is arranged between the image display panel and the surface to be projected. The optical path of the sub-frame image is shifted to achieve the synthesis of the sub-frame image as shown in FIG. 8 (a). Next, a method of moving a sub-frame image will be described. This embodiment uses an image moving element made of a disc-shaped glass plate (refractive member) 20 having three transparent areas A to C as shown in FIG. 9. The disc-shaped glass plate 20 is formed of BK7 glass with a refractive index of m. The thickness of the transparent area A is set to 0.7 mm, the thickness of the transparent area B is set to υ mm, and the thickness of the transparent area C is set to 15 mm. . This glass plate is supported in a rotatable state with the center of the disc as the axis, and the main surface of the glass plate is arranged to form 70.2 with the optical axis. Figure 10: Part of the model shows a section of a glass plate transverse to the optical axis. Assume that the angle between the surface perpendicular to the mounting axis and the main surface of the glass plate is Θ 〇, the thickness of the glass is d, and the refractive index of the glass is at the center. The public loved Ϊ 227338 A7 '----------------------- — V. Description of the invention (31) The amount of movement of the optical axis due to refraction △ X is given by the following formula Representation: Δ d · sin ^ 〇 (l-cos ^ 〇 // (ng2-sin2 θ 〇) 1/2) This embodiment is designed so that the glass thickness d of each transparent region A ~ C has different 値, and the light The amount of movement of the axis △ X changes ten cycles with the rotation of the glass plate 20. The light beam modulated by the image display panel penetrates the rotating glass plate 2 by a driving device (motor, etc.) not shown in the figure. Any one of the transparent areas a to c reaches the projected surface. In this embodiment, the optical path of the light beam that penetrates the transparent area B is shifted only by the optical path of the light beam that penetrates the transparent area A 261 &quot; m In addition, similarly, the optical path length of the light beam penetrating the transparent region c is shifted by 26.1 &quot; m only for the optical path length of the light beam penetrating the transparent region B. In addition, here Momentum (= 26 · 1 # m) is a 移动 ′ converted into the amount of movement on the image display panel, which is equivalent to the vertical distance between pixel regions to design an image moving element. The amount of movement is to adjust the thickness of each transparent area A to C Can be changed to any other value. For example, when the thickness of each transparent area A to c is 14 times, the movement amount is 26.1 X 1.4 # m. The beam movement △ X generation direction (moving direction) of this embodiment It is the same as the vertical direction of the image, but the moving direction of the light beam can also be the same as the horizontal universal direction of the image, and it can also be the same as the oblique direction.

The glass plate of the invention description (32) is rotated 9G toward the center of the optical axis. , The beam can be moved along the horizontal direction of the image. FIG. 11 shows the response curve of the light transmittance of the light portion (each pixel region) to the applied voltage in the π image display panel 8. Each pixel region of this embodiment has a structure in which the liquid crystal layer is sandwiched by electrodes. Since the response speed of the liquid crystal is limited, the light transmittance does not reach the maximum value at the instant when the voltage is applied. That is, when the light transmittance reaches the maximum level, the change from the dark state to the light-like resentment is completed, and the delay is started from the application of the voltage. In addition, there is also a time delay between the time when the stoppage is increased and the light transmission rate is minimized (zero). In this embodiment, as shown in FIG. 8 (b), it is necessary to display different sub-frame images during each sub-frame period on the image display panel. If it is necessary to not ignore the time required for the sub-frame image to switch to full display, the sub-frame image brightness in the first part of each sub-frame period is insufficient. In addition, after the sub-frame period (voltage application period) ends, the sub-frame image is still Make unnecessary display temporarily. Therefore, even if the sub-frame image moves, the previous sub-frame image is displayed due to the slow response speed of the image display panel, or it is superimposed on the next sub-frame image, and only the previous sub-frame image is displayed. At this time, doping and ghosting (double writing) such as contours occur on the synthesized frame image. The cause of the above-mentioned doping and ghosting will be described below with reference to FIG. 12. The figure 2 model shows the specific pixel rows of the sub-frame image constituting the η (n is a positive integer) frame image, and the pixel rows corresponding to the sub-frame image constituting the η + 1-th frame image. Each pixel row is arranged up and down, and the optical path of the sub-frame image is moved up and down by the image moving element. In Figure 12, it is shown that the response of the image display panel is slow. Since _____- 35- This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 1227338 A7 _____ B7 V. Description of the invention (33) Pixels with a time delay that transitions from bright to dark. For example, in the first sub-frame image constituting the n-th frame image, the "b" pixels in the bright state are shifted downward by only one pixel in the next sub-frame, but have not yet completely turned into the dark state. In the next sub-frame, only the i-pixel pixel is moved downwards again. Although it is changed to a completely dark state, the "G" pixels above the sub-frame are maintained in a slightly bright state. When there is such a slow response phenomenon, in FIG. 12, coloration occurs on a pixel adjacent to a pixel that displays white ("w" pixel) and on a pixel away from one pixel. In order to prevent the color mixing and ghosting caused by the slow response of the image display panel, when switching the sub-frame image in the image display panel, it is only necessary to avoid being modulated by the light that produces the slow response image area. Just project on the projected surface. Therefore, it is only necessary to temporarily shield a part of the optical path (light path from the light source to the projected surface) during a period of slow response, such as using a light-shielding device such as a liquid crystal shutter (Shutter) and a mechanical shutter, or temporarily turn off or Just reduce the light source. _ The same problem occurs not only during periods when the image display panel responds slowly, but also during periods when the display time of the image display panel is not consistent with the image movement time. Therefore, it is only necessary to shield the optical path during such a time inconsistency or during a time inconsistency. In addition, the image moving element of FIG. 9 can be improved, and the image moving element itself can be provided with a “light-shielding function” instead of the light-shielding device used above. As shown in FIG. 13, the image display panel in the glass plate 20 Slow response = period and period of time of inconsistency, arrange light-shielding in the section of the cross-beam "field 21, you can suppress the occurrence of color mixing and ghosting in Figure 12, and obtain higher quality ^ -36- 1227338 A7 ____B7 V. Invention Illustration (34) of the image. The central angle of the fan-shaped light-shielding region 21 is determined in accordance with the slow response of the image display panel. The smaller the ratio of the light-shielding area 21 to the entire glass plate 20, the brighter the image displayed on the projected surface. From the time when the image starts moving to the time when the next image starts moving, the relationship between the response to the image display panel from the beginning to the end on the time axis, that is, the time during the image movement, should be as shown in Figure 11. To adjust. That is, it is desirable to move the image in synchronization with a period in which each pixel region of the image display panel displays sufficient brightness. The image display panel of the present embodiment is a liquid crystal display panel using a twisted-nematic (TN) mode, but the present invention is not limited to this, and other various modes of liquid crystal display panels may be used. When a display panel capable of quicker response is used, the area ratio of the light-shielding area provided in the image moving element can be reduced, so that a brighter, higher-quality image can be obtained. When the projection-type image display device of this embodiment is used, three sub-frame images are generated during each frame, and these images are optically moved and synthesized. Therefore, the projection image display device is more than a single-plate projection using a conventional color filter. Type image display device, which can greatly improve the light utilization rate and achieve 3 times the resolution. In addition, "this embodiment uses a transmissive display panel as an image display panel", but a reflective liquid crystal display panel shown in Fig. 14 may be used. A reflective liquid crystal display panel shown in FIG. 14 is disclosed in Japanese Patent Application Laid-Open No. 9-189809. When using such a reflective image display panel, it is not necessary to use a dichroic mirror to split the white light emitted from the light source. The transmissive hologram on the display panel diffracts and splits the white light into r, G, and B light, and In the corresponding -37- this paper standard is applicable @ g 家 standard (CNS) A4 specifications (21GX tear public love) 1227338 A7 B7 V. Description of the invention (36) ----- During the 2f period, the figure The image movement is only generated 4 times. Therefore, it is possible to reduce the deterioration of the image quality caused by the slow response of the image display panel and the time lag of the image. Also. There are no colored pixels other than adjacent pixels, and the number of children of colored pixels is reduced by two-thirds compared with the first embodiment, and no image is generated. / So, in order to avoid sub-frame image movement during frame switching, the last sub-frame in each frame and the first sub-duck in the next frame only need to make the effect of the image moving element on the light beam the same, or stop An image moving element can be moved. An example of such an image moving element for image movement is shown in FIG. 16. This image moving element includes a glass plate 22 having transparent areas A to F. The transparent areas E &amp; F are formed of 149iFK5 glass with a refractive index, the transparent areas A and D are formed of BaK4 glass with a refractive index of 1.57, and the transparent areas b and C are formed of SF2 glass with a refractive index of 1.64. The thickness of each transparent area is 2.0 mm. The optical axis of the main surface of the disc-shaped glass plate 22 having such a structure is 65. Angle. The glass plate 22 is rotated while synchronizing the time of the optical path length of each transparent region with the time of switching to the corresponding sub-block. As a result, transparent areas a and 0 move only 34.0 # m optical path to transparent areas E and F, and transparent areas b and c move only 2 6.6 // m optical path to transparent areas A and D. For example, the transparent area F corresponds to the first subframe of the n-th frame shown in FIG. 15. At this time, the transparent region A corresponds to the F-th subframe of the n-th frame, and the transparent region β corresponds to the last subframe of the n-th frame. The transparent area c corresponds to the n + 1's first child Φzhen '. The transparent area D corresponds to the next child Zhongzhen in the n + 1th frame.

區域E對應於第n+1幀的最後子幀。 因透明區域B與透明區域c具有相同的折射率及厚度,所 以光程的移動量也相同,如圖15所示,在對應之兩個子幀 圖像間不產生移動。同樣的,在透明區域E與透明區域 也不產生移動。 此處爲便於説明透明區域B&amp;c、以及透明區域e&amp;f,係 分別將其區分成兩個區域(圖16中以虛線區分),不過實際 上,可刀別以一塊連續的構件構成。因此,圖16之圓盤狀 玻璃板2 2可組合4個扇形透明構件來製作。 本貫施形態也因圖像顯示面板之應答緩慢等因素,而在 圖像移動與子幀切換之間發生時間不一致。因而,如圖j 7 所示’宜在玻璃板22的適切部分設置遮光區域2 1。圖17 中’在應該進行圖像移動的兩個區域邊界(透明區域A及d 的各兩側)設置遮光區域21即可。 本實施形態也使用TN模式的液晶顯示面板作爲圖像顯示 面板,不過,亦可使用其他各種模式的液晶顯示面板。若 採用可更快速應答的顯示面板時,由於可以縮小設置在圖 像移動元件内之遮光區域的面積比率,因此可獲得更明 亮、高品質的圖像。此外,本實施形態係使用穿透型顯示 面板作爲圖像顯示面板,不過亦可使用圖14所示的反射型 液晶顯示面板。 採用本實施形態之投影型圖像顯示裝置時,因使用無彩 色;慮光器的圖像顯示面板,在各巾貞期間生成3個子賴圖 像,使這些圖像作光學性的移動並合成,所以比使用先前 -40-本纸張尺度適用中國國家標準(CNS) A4規格(210 X 297公釐) 1227338Region E corresponds to the last subframe of the n + 1th frame. Since the transparent region B and the transparent region c have the same refractive index and thickness, the movement amount of the optical path is also the same. As shown in FIG. 15, no movement occurs between the corresponding two sub-frame images. Similarly, no movement occurs in the transparent area E and the transparent area. Here, the transparent area B &amp; c and the transparent area e &amp; f are divided into two areas (denoted by dashed lines in Fig. 16) for the convenience of explanation, but in practice, the knife can be composed of a continuous member. Therefore, the disc-shaped glass plate 22 of Fig. 16 can be manufactured by combining four sector-shaped transparent members. In this embodiment, due to factors such as the slow response of the image display panel, time inconsistencies occur between image movement and sub-frame switching. Therefore, as shown in Fig. J7 ', it is desirable to provide a light-shielding area 21 at a suitable portion of the glass plate 22. In FIG. 17 ′, the light-shielding region 21 may be provided at the boundary of the two regions (on both sides of the transparent regions A and d) where the image should be moved. In this embodiment, a TN mode liquid crystal display panel is also used as the image display panel. However, other various modes of liquid crystal display panels may be used. When a display panel capable of quicker response is used, the area ratio of the light-shielding area provided in the image moving element can be reduced, so that a brighter, higher-quality image can be obtained. In this embodiment, a transmissive display panel is used as the image display panel, but a reflective liquid crystal display panel shown in Fig. 14 may be used. When the projection-type image display device of this embodiment is used, an achromatic image display panel is used to generate three sub-images during each frame period, and these images are optically moved and combined.

In addition, since the sub-frame image does not move during frame switching, the color mixing and ghosting caused by the slow response of the image display panel can be greatly reduced. (Third Embodiment) Next, a third embodiment of the present invention will be described. The projection-type image display device of the present embodiment basically has the same structure as that of the first embodiment, and the main difference lies in the composition and movement method of the sub-frame image. The differences will be described below. As shown in FIG. 18, the number of sub-frame images constituting each frame image in this embodiment is two. Each sub-frame image is sequentially displayed at two different positions on the projected surface. Therefore, each frame constitutes one pixel on the projected surface by a total of three pixels of one pixel of the first sub-frame image and two pixels of the second sub-frame image projected in the vicinity. The other one pixel adjacent to the above-mentioned one pixel on the projected surface is the opposite, and the two pixels of the first sub-frame image and the one pixel of the second sub-frame are combined. As a result, although the resolution of the image formed on the projected surface is slightly reduced, since each sub-frame can be composed of two sub-frames, it is not necessary to quickly drive the image display panel, and the color mixing caused by the slow response can be reduced. This embodiment uses an image moving element configured to display a sub-frame image at two different positions on the surface to be projected. The image moving element may be composed of a glass plate having two transparent regions having at least one of a refractive index and a thickness different from each other.

When the display of the last sub-frame of the original picture frame constituting the image signal has not ended, but it becomes the display time of the next sub-frame, the original picture towel that only needs to be kept It is only necessary to display the first sub-frame of the newly-formed original image frame in the normal image signal. Because the image information does not change greatly between frames or between sub-frames, even if the frequency of the display frame and the There is a difference between the frame frequencies of the original image, and it is still possible to display without discomfort. Therefore, this embodiment does not significantly damage the display quality and can simplify the structure of the device. In addition, unlike the third embodiment, this embodiment The image moving element of the form displays the sub-frame image at three different positions on the projected surface, so the image moving element used in the first embodiment is used directly to reduce its rotation speed to one third. 2 is enough. Although a liquid crystal display panel of the TN mode is also used as the image display panel in this embodiment, liquid crystal display panels of other various modes may be used. When a display panel capable of quicker response is used, the area ratio of the light-shielding area provided in the image moving element can be reduced, so that a brighter, higher-quality image can be obtained. In this embodiment, a transmissive display panel is used as the image display panel, but a reflective liquid crystal display panel shown in Fig. 14 may be used. -When the projection type image display device of this embodiment is adopted, an image display panel without color filters is used to generate two sub-frames in each frame period. -43- This paper standard applies Chinese National Standard (CNS) A4 Specifications (210X 297 mm) 1227338 A7 ____ B7 V. Description of the invention (41) These images are optically moved and combined, so they are better than the single-plate projection image display using the previous I-shaped color filter Device, which can greatly increase the light utilization rate and achieve higher resolution. (Fifth Embodiment) Next, a fifth embodiment of the present invention will be described. The projection type image display device of this embodiment basically has the same structure as that of the second embodiment. The main difference is the configuration and movement method of the sub-frame image. The differences will be described below. The number of sub-frame images constituting each frame image in this embodiment is 4. Each sub-frame image is sequentially displayed at three different positions on the projected surface, and constitutes 4 sub-frame images of each frame image. The two sub-frame images in the image are displayed at the same position on the projection surface. That is, in the subframe data generated in the same manner as the i-th embodiment, the subframe in this embodiment displays the second subframe in each frame at the end again, and each frame image is composed of a total of 4 subframes. This will be described in detail below with reference to FIG. 20. The image movement in this embodiment is roughly carried out at a pixel pitch, and the first and third sub-frame images are moved upward and downward, respectively, based on the second and fourth sub-frame images in each frame. That is, each frame is composed of four sub-frames, and one cycle of movement is performed by four image movements. In this embodiment, the image is reciprocated on a frame unit cycle, so the image can always be moved to three different positions in one pixel unit. Therefore, even within a frame or between frames, since the image can be always moved in units of ^ pixels, it is possible to prevent the ghosting shown in FIG. 20 from occurring. -44-

Each of the sub-frames can also be represented by 5 or more sub-frames. At this time, it is suitable to disperse several sub-images for black display in each frame so that the number of display times of each color is the same in each frame. Therefore, L is displayed in the two sub-frames at the same position on the projected surface. The image can also be composed of sub-frame images with reduced brightness, instead of inserting sub-frames displayed in black into each frame. Specifically, the display image signal can also be corrected to make the second and fourth sub-frame images of each frame The total light amount of the image is equal to the light amount of the first or third sub-frame image. In this way, the color balance between the pixels is good, and the pixels are always displayed, so the flickering feeling is also reduced. The amount of correction for this display image signal Since the same correction is always applied to the entire pixel and each frame, a simple circuit can be constructed. As shown in FIG. 22, the image moving element used in this embodiment is a glass plate 23 having four transparent areas. Made up. The bright area a is formed of FK5 glass with a refractive index of 1.49, the transparent areas b and 0 are formed of BaK4 glass with a refractive index of 1.57, and the transparent area c is formed of SF2 glass with a refractive index of ι · 64. The transparent areas A to D The thickness is 2.0 mm. The glass plate 23 crosses the optical path so that its main surface forms an angle of 65 ° with the optical axis. The transparent areas A to D correspond to the rotation of the sub-images. Therefore, the transparent areas B and D On the transparent area A, the light beam only moves upward by 34.0 // m, and on the transparent area C, the light beam moves only 26.6 ^ 111.-Although this embodiment also uses a TN mode liquid crystal display panel as the image display panel, it can also be used.

Description of the invention (43) When a display panel capable of quicker response is used, Since the area ratio of the light-shielding area provided in the image moving element can be reduced, a brighter, high-quality image can be obtained. In addition, this embodiment uses a transmissive display panel as the image display panel. The reflection type liquid crystal display panel shown in Fig. 14 can be used. When the projection type image display device of this embodiment is used, an image display panel without color filter sound is used to generate four sub-frame images during each frame period. These images are optically moved and combined, so that compared with the single-plate projection image display device using the conventional color filter, the light utilization rate can be greatly improved and the resolution can be tripled. Therefore, the present invention The projection type image display device divides each frame image into a plurality of sub-frame images in a time-sharing manner, and moves and overlaps the sub-frame images to synthesize the original frame image. The time for moving the sub-frame image should be equal to that of the sub-frame image. Time synchronization of switching sub-frame images on the image display panel. There are roughly two ways to switch sub-frame images. The first method is the "Line Scan" method. This method is based on the image display panel. Each column or column drives several pixel areas arranged in rows and columns. It is displayed vertically from the top to the bottom of the screen. New sub-frame image. The screen is divided into several blocks, and the method of scanning each row also belongs to the "line scanning method". In addition, the second method is the "surface (uniform) writing method". This method is to uniformly drive all of the pixel areas arranged in rows and columns in the image display panel, and simultaneously display new sub-pixels on the entire screen. Tilt the image. _ The invention is not limited by the type of scanning method. The following first describes the implementation of the "line scanning method". -46- 1227338 V. Description of the invention (44) (sixth embodiment) Figs. 23 (a) to (g) are displayed on the image display & M panel, and the sub-frame image is scanned by line scanning. Switching situation. (Figure 23〇) 鼗 千 椹 鹿-工 &gt; μ, and human shoulder π only display the pixel area of the first column of the display panel is switched to display the new sub-block diagram silly (_ ^ 口 诼 (such as a sub-frame image ). The pixel area after this temple continues to display the old sub-clip image (such as the first sub-pa image). Figures 23 (b) ~ (g) move the column below the screen line by line, The display area of the new sub-frame image is gradually enlarged and rebellious. Fig. 23 (g) shows the new sub-frame image on the pixel area of the first to seventh columns. Therefore, the drive-by image is hidden from the general line. The image display panel switches between sub-frame images, and the boundary between the new sub-frame image and the old sub-frame image is adjusted at each level (1H). At this time, the time at which the voltage is applied in Figure JJ starts at each The scanning lines (columns) are separated by a certain interval. Therefore, when using an image display panel driven by line scanning, each pixel should synchronize the time when the image display of a new sub-block is started with the time when the image moving element starts the optical path movement. Therefore, it is appropriate to increase the speed of the display area of the new sub-cap image (scanning line moving speed) and the movement of the image moving element. Speed of field increase—to 〇 • i The following describes various aspects of the image moving element suitable for this kind of operation. As shown in FIG. 24, the image moving element of this embodiment is a glass plate 24 having 6 transparent areas. The transparent area VIII and 0 are formed by FK5 glass with a refractive index 丨, the transparent area 3 and £ are formed with glass with a refractive index 丨 ^, and the transparent area C &amp; F is formed with a refractive index 丄 64 of 31: 2 It is made of glass. Its thickness is uniformly 2.0 mm. By inserting the image moving element, the main surface of the glass plate 24 is shaped as an optical axis. -47- This paper size applies to China National Standard (CNS) A4 (210X 297mm) (%) 1227338 A7 _______B7 V. Description of the invention (45 ~) — --- At an angle of 65 °, the transparent area is 8 and 0, the transparent area 6 and £ are only moved by 34.0vm, and the transparent area C &amp; F is only moved by 26 6 & quot m. Each transparent area corresponds to a display sub-frame. Because the thickness of the glass plate 24 is constant in this image moving element, it can still rotate quietly and stably even at high speed. In addition, in order to suppress the description in the above embodiment, Because the image display panel should The color mixing caused by the slowness, as shown in FIG. 25, is preferably provided with a light-shielding region 21 between the transparent regions. In addition, similar to the glass plate 20 of FIG. 9, only inexpensive βκ7 glass can be used as the glass material In this case, since the thickness of each transparent region can be freely selected, a more accurate image moving element can be obtained at a low cost. The improved example of the image moving element is that the transparent regions 8 and 0 are formed by the cutout portions of the glass plate 24. BK7 glass with a refractive index of 1.52 can also be used for other transparent areas. At this time, the thicknesses of the transparent areas b and e are set to 0.7 mm, and the thicknesses of the transparent areas C and F are set to 1. 4 mm. The optical axis of the main surface of the glass plate 24 was 83 · 8. When the angle is 0, the transparent area B, E can move to 26.0 a m with respect to the transparent area A, D, and the transparent area c, F can also move with 26.0 // m to the transparent area B, E. With this structure, the image moving element can be made lighter. In addition, since the sub-pictures corresponding to the transparent areas A and D do not penetrate the glass, a sharpening effect is also exhibited. The other image moving element is constituted by a glass plate 24 having six transparent regions, and the following method may be adopted. That is, the transparent regions A and D are formed of FK5 glass having a refractive index of 1.49 and have a thickness of 2.0 mm. The transparent areas B and E are formed of BK7 glass having a refractive index of 1.52 and have a thickness of 2.09 mm. Transparent area -48- 1227338 A7 B7 V. Description of the invention (46) C and F are formed by SF2 glass with refractive index 丨 .64, and its thickness is 20mm. At this time, the glass plate was inserted so that the optical axis formed 65. When the angle is 0, the transparent area ME can achieve 9-image movement to the transparent area, and the transparent areas C and F can achieve% m image movement to the transparent area B &amp; e. In this way, by selecting a glass plate that is easier to mass-produce and adjusting its thickness so that the thickness difference between transparent areas is small, a more accurate image moving element can be manufactured at a low cost. In addition, although the main part of the image moving element is composed of a transparent plate formed of a glass material, the image moving element of the present invention is not limited to this. It can also be a transparent material that forms optical path refraction, or a resin such as plastic. As described above, in order to use a transparent plate that is oblique to light and move the optical path of the sub-transformed image, it is only necessary to make a transparent plate that has at least several transparent regions with different refractive indices and thicknesses. The thickness of the translucent sun plate is easy to adjust by surface grinding and engraving techniques. The main surface of the transparent plate is tilted by 45 to 85. When the angle of the lens is at a suitable angle, you can select the appropriate value from the range of refractive index 1.45 ~ 1.7 to achieve the necessary image movement. Since a transparent plate having such a refractive index can be formed of a general glass material, an image moving element can be manufactured at low cost. Tilt the main face of the transparent plate to the mounting axis by 66 ~ 88. In the range of 0.5 to 2.0 mm, the appropriate thickness of the transparent plate is selected, and the necessary image movement amount can be achieved. In addition, when the main surface of the transparent plate is tilted at an angle of 6 ° to 80 °, the thickness of the transparent plate is selected within the range of 0.5 to 2.0 mm. The range is 1.45M.7. Select the appropriate index of the refractive index-= -49- This paper size applies the Chinese National Standard (CNS) A4 specification (21〇X297 public love) 1227338 A7 ____ — B7 V. Description of the invention (47) The necessary image movement can be achieved the amount. (Seventh Embodiment) When a line scan is performed in the vertical direction of the screen, as shown in FIG. 26, the boundary portion between the n-th sub-frame image and the η + 1-th sub-frame image (the boundary of image switching), The horizontal line is divided into points to indicate that the line part moves from top to bottom. When the image rotation is performed using the rotation plate, as shown in FIG. 26, in the glass plate 24, the boundary line of the adjacent transparent area (the boundary of the image movement area) is rotated around one point. The boundary line and the switching of the sub-frame image are not parallel to each other, and deviation occurs. When such a deviation occurs, a part of the sub-frame image that should be moved is not actually moved, and a part of the old sub-frame image that should not be moved is instead-moved. In order to eliminate such disadvantages, as described in the first embodiment, various methods can be used to prevent the light of the image display panel from being projected on the surface to be projected only during the time deviation described above. In order to eliminate the above-mentioned disadvantages, a glass plate 25 having three transparent areas as shown in FIG. 27 is used to constitute an image moving element instead of providing a light shielding portion to drive the device to make the glass plate 25 up and down. The direction moves back and forth, thereby moving the image.

Description of the invention (48) 26.6 &quot; m image movement. In this embodiment, in the glass plate 25, the boundary position of the adjacent transparent region (the boundary of the image moving region) and the boundary of the image switching can be matched. Therefore, since any pixel displaying image information of a new sub-frame is moved at an appropriate time, an image with less color mixing can be obtained. In addition, even when the image moving element of this embodiment is used, problems such as color mixing may occur due to the slow response of the image display panel. In this case, a light-shielding region (not shown in the figure) should be provided at the boundary portion of each of the transparent regions a to C shown in FIG. 27. In this embodiment, the scanning line of the image display panel and the boundary lines of a plurality of transparent regions are roughly parallel, and the image is moved in synchronization with the switching of the image. In order to achieve this kind of image movement, the present embodiment is to make the glass plate 25 as shown in FIG. 27 reciprocate. However, if the boundary line of each transparent area can maintain a parallel relationship with the scanning line of the image display panel, Use other means. For example, the transparent regions A to C shown in FIG. 27 may be formed by other glass plates 26, and these glass plates 27 may be driven by a driving device shown in FIG. 28. By adopting this driving method, the boundary lines of several transparent areas and the scanning lines of the image display panel can be maintained in a substantially parallel relationship, so that they can move synchronously with the line scanning. In addition, the same effect can be achieved even if the transparent plates corresponding to the transparent areas A to C are arranged on the same optical path, and the staggered rotations sequentially reach the optical path. (Eighth Embodiment) Next, another embodiment of the image moving element will be described with reference to Figs. 29 to 31. The image moving element of this embodiment is designed to be on the surface to be projected. -51 · This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 1227338 A7 _ B7 V. Description of the invention (49) It consists of a plurality of micro prisms or diffraction gratings with different movement amounts, and the image movement is performed by the image movement element in and out of the optical path. First, refer to FIG. 29. In this embodiment, a prism surface of a minute prism plate formed of glass having a refractive index? 1 is covered with a resin material having a refractive index? 2. When the light incident perpendicularly to the non-smooth surface (smooth surface) of the tiny prism plate is changed by the angle Θ !, only the image of the one-pixel portion of the projected surface moves. Furthermore, it is assumed that the distance between the image areas on the image display panel 8 is p, and the distance between the pixel area surface of the image display panel $ and the prism surface (refractive surface) is Z. In this embodiment, the structure of the micro cymbal plate is designed. In this embodiment, FK5 glass is used as the material of the micro prism plate, and the surface of the prism surface is LOCKTIGHT 363 manufactured by LOCKTIGHT Company as a UV hardening resin for leveling the concrete surface. Assume that the pixel area's pitch P is 26 A m, the distance Z is 5 mm, the tilt angle of the micro prism is P 2 (= the angle of incidence of the light into the tilted surface of the micro prism), and the light is refracted by the micro chirp. When the angle is Θ 3, θ 1 is 0.3 ° according to the above formula. At this time, since the refractive index of the glass is nl and the refractive index of the resin is ", the relationship between Θ 2 and Θ 3 is based on the Schrödinger d · 3 = η 2 · si ^ and has a relationship. Therefore, if 1;] ^ 5 The refractive index of glass is 1.487, the refractive index of LOCKTIGHT 363 is 152.0, and the inclination angle Θ 2 of the minute 稜鏡 is 13.7. In this case, the amount of movement equivalent to the pitch p can be obtained. When various parameters satisfy the above formula, they are not limited to the material and number of this embodiment. In addition, it is not necessary to level the resin.

Description of the invention (50) The prism surface can also be omitted. When the prism plate and the diffraction grating shown in FIG. 29 are used as the image moving element, the distance between the image display panel 8 and the image moving element is limited to a certain distance Z. After the above optical design is completed, the The distance cannot be changed to any size. In order to obtain an image moving element that can be inserted at any position on the optical path without being restricted by the above, as shown in FIG. 30, the above-mentioned micro diaphragm or diffraction grating may be opposed to each other. A resin material having a refractive index n2 different from these materials may be filled between a pair of minute prism plates or a pair of diffraction gratings. Two tiny prism plates can be formed from SF2 glass. These two tiny prisms can be glued using LOCKTIGHT's UV hard 4 dagger tree locker LOCKTIGHT 363. The distance Z between the tiny prism plates can be 1 mm. At this time, since the refractive index of SF2 glass is 1.64 and the refractive index of LOCKTIGHT 363 is 1.52, the inclination angle Θ of the 'micro prism' is 19.6. At this time, the movement amount ΔD of the optical path is about 2 6 a m. In order to display the sub-frame image between three different points on the projected surface, it is sufficient to make the element 27 of the element shown in Fig. 29 and Fig. 30 in the combination shown in Fig. 31. The element 27 is designed so that the areas A and B have different amounts of movement AD, respectively. If such an element 27 is operated periodically, it is not inserted into the optical path during a certain sub-frame, and is inserted into the optical path during other sub-frames, so that a proper image movement can be achieved. In the examples of FIGS. 29 and 30 described above, although the beam movement occurs in the direction of the drawing on the paper surface, the movement direction of the boundary line of the movement area and the movement direction of the beam can be considered separately. Therefore, the movement direction of the beam is not =

Description of the invention (54) A micro ridge array is formed on the end surface. In more detail, the image moving element of this embodiment is a transparent substrate formed by a micro prism array i3 whose surface is covered with a transparent electrode and an orientation film, and the surface is covered with a transparent electrode 11 and an orientation film i2.

In this embodiment, a micro chirped array i3 is formed of a material having a refractive index close to ne2. When no voltage is applied, a refractive index difference occurs between the liquid crystal layer and the micro prism array i3, so the light beam entering the micro prism array i3 is refracted according to Snell's law. In addition, when a voltage is applied, the refractive index difference between the liquid crystal layer and the micro prism array i3 decreases according to the magnitude of the applied voltage. As the refractive index difference decreases, the refraction angle of the light beam entering the micro prism array i3 also decreases. If the apex angle of the micro prism is Θ 4 and the refractive index of the micro prism array i3 is n2, the beam refraction angle J when no voltage is applied to the liquid crystal layer i5 is expressed by the following formula: ά = (ne2-n2) X θ 4 In addition, when increasing the refraction angle, a liquid crystal layer having a large refractive index anisotropy should be used. When two of the above-mentioned elements are combined and arranged in the state shown in Fig. 3, an image moving element in a conventional form is formed.

After that, the same operation is repeated, and the second sub-frame image in FIG. 6 is displayed on the image display panel 104. When the third sub-frame image is displayed, the start pulse signal and the selection signal are applied. The time delay is only 1 second. Therefore, the third sub-frame image shown in Fig. 6 can be displayed.-The frame memory can also start to read the addresses at the addresses corresponding to the scanning lines 1 to 3. Instead of shifting the application time of the above-mentioned start signal every sub-frame instead. In this example, it is explained that the pixel regions for R, G, and B are respectively arranged in parallel with the cat line, but the present invention is not limited to such a system. When the period of 1Η is replaced with a dot clock cycle, it corresponds to a system operation using an RGB linear bar type image display panel in which the pixel regions of r, 0, and B are arranged perpendicular to the scanning line. Although the circuit of Fig. 38 is not provided with a frame memory specifically for storing sub-frame image data, such a frame memory may be provided to temporarily store the sub-frame images. _ (12th embodiment) The following is a description of a projection type image display device having two image display panels. _ -62- This paper size is in accordance with China National Standard (CNS) A4 (210 X 297 mm) ) 1227338 A7 B7 V.

In addition, the second image display panel 28 displays an image composed of only G colors. This image has the pattern shown in Fig. 4 (c), and reflects the G-color data related to all pixels of the f image. The second image display panel 28 does not need to be divided into sub-frames to display the image. Therefore, in order to find out, the balance of r, G, and B color light projected on the projected surface is appropriate. The compensation degree between the two image display panels 28 or the compensation display period. For example, the image display period projected from the second image display panel 28 and projected on the screen may be limited to: approximately one-half of the frame period, or replaced with a reduced brightness. In this embodiment, only two colors of r, G, and b colors are displayed on the first image display panel 18. The other color is displayed on the second image display panel 28. Each microlens on the first image display panel 18 separates the incident light into two colors and focuses the light in the corresponding pixel area. Therefore, the pitch and focal distance of the microlens 7 can be 2/3 of the distance and focal distance between the single-plate microlenses 7 As described above, the present invention moves several sub-frame images by moving the sub-frame images.

Description of the invention (62) '~-Reduced. When the line-of-sight moving speed is roughly equal to the moving speed of the sub-frame image, the movement of the sub-cap image cannot be seen. As a result, the pixel arrangement on the image display panel is observed, and the resolution is reduced to the degree of the pixel arrangement constituting the image display panel. μ This phenomenon is caused by the moving direction and speed of the line of sight and the moving direction and moving speed of the sub-frame image. Therefore, the effect of this phenomenon can be reduced by specially designing the zipper image motion pattern. The reduction effect can be precisely evaluated by investigating the rows of pixels along the sub-frame image moving direction (such as the y direction), and examining the spatial frequency ㈣ (spectrum) of the pattern of plane pixels 并 juxtaposed along the time axis (t axis). helmet. This planar pixel arrangement is a pattern in which the vertical axis is the y axis and the horizontal axis is the time axis (t axis). In order to analyze the moving pattern of the sub-images moving in the y-axis direction on the projected surface, the pixels in the unitary space can be arranged in a plane Fourier transform to effectively evaluate the spatial frequency in the y-axis direction and the t-axis direction Related spectrum. The pixels ㈣ in y_t space, because the pixels have a pattern arranged regularly on the raster points, their spectrum shows a substantial local point in Fourier life (fy-ft space). An example of the frequency levels obtained by the two β Fourier transform of the pixel arrangement in the 3M space shown in Figure 15 is shown in Figure 42. In FIG. 42 (a), each station point indicated by the symbol 0 corresponds to the spatial frequency of the pixel arrangement in the y_t space. When the sub-image is moved in a relatively monotonous pattern as shown in FIG. 15, when the line of sight is moved toward the gimbal ’at a specific speed, the aforementioned phenomenon suddenly occurs. To avoid it, Ma needs to complicate the moving pattern of the sub-ton image ... The frequency is dispersed into many components. Specifically, it is tied in y-t space, such as 2

The space frequency of the pixel arrangement of yt Shima whispers you. When you use a fork and a hand knife, the local points of the spectrum in Chuanye space are also scattered. Therefore, the image that determines the yt space is awkward. Do n’t disturb you. The private i distinguishing pattern makes the local points in the Fourier space (fy-ft space) more scattered, and it is easy to make a fuss. + Do not suppress the disadvantages of the above phenomenon at a specific line of sight movement speed. In addition, determine yt When the pixel arrangement pattern in space keeps the symmetry of the local points in Fourier space to the fy axis, it is easy to suppress the disadvantages of the above phenomenon in a specific direction of sight movement. _ Furthermore, the pixel arrangement pattern in yt space is determined to make Fourier Leaf space When the local point is located as far as possible within the area of fy &lt; ft, the above phenomenon is not easy to occur at a relatively slow moving speed of the line of sight. The present invention forms pixels of a desired color by overlapping three pixels of RGB in time, The image is composed of a combination of three sub-frame images that move with each other as a unit.

Description of the invention (5 ~ '~ &quot; In the embodiment described later, these sub-sets are appropriately combined to form a moving pattern to prevent the display quality from being degraded due to the movement of the observer's line of sight. In addition, the above caused by the movement of the line of sight causes the above The effect of the phenomenon can also be reduced by carefully designing the pixel arrangement of the image display panel. That is, this phenomenon occurs most significantly when the movement of the Ziton image is completely consistent with the movement of the line of sight. The person observes the actual pixel arrangement on the image display panel. Therefore, the pixel arrangement (x_y space) on the image display panel is Fourier-transformed and can be evaluated in Fourier space. Specifically, it is desirable to meet the RGB The condition that two pixels are arranged in a straight line along the moving direction. At the same time, in the Fourier space of the pixel arrangement (xy space), try to choose a pixel arrangement that has a local point farther away from the origin (xy space). When such a pixel arrangement (xy space) is used, the spatial resolution of each color is improved. In the following description, the moving pattern of a sub-frame image is considered in consideration of the above matters.

Description of the Invention (65 forms of the combination of Figure 44. The i-period of the moving pattern contains two (+ y = and = twice) movements of two pixel parts. The movement of Figure 44 is merged, and it is passed on. In the space, there is a local part of the spectrum shown in Fig. 42 (b). Comparing "" with Fig. 42 (a), although the i-period of the moving pattern is composed of the same number of children, it is easy to understand the local points shown in Fig. 42 (b). Therefore, 'this embodiment is less prone to the above-mentioned phenomenon when a specific line of sight movement direction and a specific movement speed are adopted. In addition, since the six sub-frames constitute a cycle, the cycle is relatively short. The structure of the image moving element is relatively simple. The moving pattern of the sub-images used in this embodiment can also be composed of 2 sub-frames or 1 frame. This type of image movement is also used. An example of an image moving element is shown in Figure 45. The image moving element is provided with a glass plate 22e, which has transparent areas A to F. The transparent areas VIII and 〇 are formed of glass with refractive index 149iFK5, and the transparent areas B and F From the refractive index ^ The transparent regions C and E are formed of SF2 glass with a refractive index of 1.64. The thickness of each transparent region is 2.0 mm. The main surface of the disc-shaped glass plate 22e having such a structure is 65. Therefore, 'synchronize the time of the transversal optical path of each transparent region with the time of switching to the corresponding one, and rotate the glass plate 22e. With this, the transparent regions b and F move to the transparent regions A and D, and the optical path moves only 34.0 〆m, transparent areas C and E versus transparent areas B and F, and the optical path moves only 26_.6ym.

Description of Invention (66) Should. In this embodiment, a time lag between image movement and sub-frame switching also occurs due to factors such as the slow response of the image display panel. Therefore, as shown in Fig. 17 ', it is preferable to provide a light-shielding region 21 at a proper portion of the glass plate 22. In FIG. 17, it is only necessary to set a light-shielding area 21 at the boundary of the two areas (both ends of the transparent areas A and D) where the image should be moved. Of course, the image display device may use the image moving device described in the other embodiments. In this embodiment, the pixel arrangement of FIG. 46 is adopted as the pixel arrangement of the image display panel. For example, the Fourier spatial state of the pixel arrangement of Fig. 47 and the pixel arrangement of Fig. 46 are shown in Figs. 48 (a) and (b), respectively. It is determined in Fig. 48 (a) that there are local points at a position farther from the origin. The intervals between the straight lines connecting the pixels of the same color shown in FIG. 46 and FIG. 47 are narrower in FIG. 46, that is, the spatial frequency of each color is high. As can be seen from the above, by adopting the pixel arrangement shown in FIG. 46, even though the line of sight movement is roughly the same as that of the sub-picture image, the pixel arrangement of the image display panel can be recognized, but it has less adverse effect on the image quality. The projection type image display device of this embodiment also uses an image display panel without a color filter to generate three sub-frame images during each frame period, and optically moves and synthesizes these images. Compared with the single-plate projection image display device using the previous color filter, the light utilization rate can be greatly improved, and the resolution can be 3 times. Of course, two sub-frame images may be generated during each frame, and these images may be optically moved and combined. Although there are some movements in the animation that are not smooth, but because of the sub-69- size of this paper, the Chinese National Standard (CNS) A4 specification (210X297 mm) 1227338 V.

Order the 13th implementation mode, as shown in Fig. 44. The L period of the moving pattern of the sub-frame image consists of 6 sub-frame images (subset 1A &amp; 2B). ), This embodiment is shown in FIG. 49, and one cycle of the moving pattern of the sub-picture is composed of 18 'j images (6 sub-sets). This embodiment is a group A from the sub-set. Selector set 1A and subset 3A. After selecting the subset and subset 2B from the subset's Saki, the ° turn of the subset of the A group and the B group is interactively configured. Refers to moving only in the + y direction and moving and _ y direction. The execution is performed a slightly equal number of times, so that even if the observer moves the line of sight in a certain direction, the possibility of the line of sight moving in line with the direction of the image is halved, and in addition, even if the direction is not consistent, the time is not continuous. More than 3 sub-frame periods. The Fourier space state of the moving pattern of ® 49 is shown in Fig. 42 (a).

The naked eye method confirmed the effect of the moving pattern on π repeatedly at 10 Hz. Although the number of sub-frames exceeding 8 may constitute one cycle of the moving pattern ', if the first cycle is too long, the naked eye may recognize the periodic change of the moving pattern, which may cause the display quality to deteriorate. Therefore, one cycle of the moving pattern should preferably be composed of 18 or fewer subframes. According to the moving pattern of the sub-frame image used in this embodiment, two sub-frames can be used to form a frame, or three sub-caps can be used. An example of an image moving element suitable for use in this embodiment is shown in FIG. 5. The image moving element includes a glass plate 22 having transparent areas a to R.

The glass plate 22k is rotated by synchronizing the time at which each transparent region crosses the optical path with the time at which it is switched to the corresponding sub-frame.

Description of the invention (70) There are double or triple images, which may cause the image quality to deteriorate significantly. Therefore, when two or more liquid crystal layers are used, and three different positions are selected in the state where voltage is applied to the liquid crystal layer, even if the transition from ON to OFF is slow, the picture needs to be driven. Mobile components that do not deteriorate. The driving method of the image moving element which has been improved so as not to cause the above problems will be described below. (15th embodiment) The image moving element of this embodiment has two elements as shown in FIG. 32 (or FIG. 33), and these two elements are arranged in series on the optical path as shown in FIG. 53. In this embodiment, a crystal plate g3 and a crystal plate g4 having birefringence are used to constitute an image moving element. With this image moving element, three different positions on the surface to be projected can be selected by applying a voltage to the two liquid crystal layers of the light entrance end and the light exit end located on the optical path. The three different positions selected are composed of a voltage state (ON / OFF) applied to the first liquid crystal layer (light emitting end) and a voltage state (ON / OFF) applied to the second liquid crystal layer (light emitting end). Decide. Fig. 55 is a model showing a state change when a voltage state is applied to the liquid crystal layer at the light entrance end and the light exit end. For example, there are two states in which a voltage is applied or not applied to the liquid crystal layer on the light input end, and the states are further subdivided from these states by applying a voltage state to the liquid crystal layer on the light output end. At this time, because the light input end is in a voltage-applied state, the direction of the polarization plane of the light entering the liquid crystal layer of the light output end is changed by 90 °. State of applied voltage -73- This paper size is in accordance with Chinese National Standard (CNS) A4 (210X 297 mm) 1227338 A7 B7 5. Description of the invention (71) State change is just the opposite relationship. Therefore, the state changes of the composition of the voltage application state to the light input end and the light output end are two kinds of components shown in FIG. In this specification, the above two components are referred to as Γ Type A "and" Type B ", respectively. Therefore, the positions of the three different sub-frame images are represented by states A, B, and C. In addition, in order to indicate the voltage application state of the two liquid crystals, if the liquid crystal application voltage state of the light input terminal is ON and the light output terminal voltage state is OFF, it is noted as Γ ON · OFF ". At this time, Γ OFF · ON of Type A is state A, "OFF · OFF" or "ON · OFF" is state B, and "ON · ON" is state C. In addition,

TypeB 的「OFF · OFF」爲狀態 A,Γ OFF · ON」或 Γ ON · 〇N」爲狀態B,「ON · OFF」爲狀態C。另外,狀態A,B 及C亦可對應於被投影面上三個不同位置的任何一個。 若Type A進行狀態Ao狀態B的變化,Type B進行狀態 B&lt;=&gt;C間的變化時。Type A於「OFF · ON」所定義的狀態A 與「ON · OFF」所定義的狀態B之間產生轉移。此外, Type B於「OFF · ON」所定義的狀態B與Γ ON · OFF」所 定義的狀態C之間產生轉移。 此時,因參照圖5 1及圖52説明之液晶的應答特性,造成 Type A在進行狀態Αθ狀態B的變化過程中,暫時存在兩液 晶層同時處於施加電壓狀態(「ΟΝ · ON」狀態)。同樣 的,Type B在進行狀態B&lt;=&gt;C間的變化過程中,暫時存在兩 液晶層同時處於施加電壓狀態(「ΟΝ · ON」狀態)。如圖 56的粗箭頭所示,「ΟΝ · ON」在Type A中定義狀態C,在 -74- 本紙張尺度適用中國國家標準(CNS) A4規格(210 X 297公釐) 1227338 A7 B7 五、發明説明(72 )"OFF · OFF" of TypeB is state A, Γ OFF · ON "or Γ ON · ON" is state B, and "ON · OFF" is state C. In addition, states A, B, and C can also correspond to any of three different positions on the projected surface. If Type A changes state Ao and state B, Type B changes state B &lt; = &gt; C. Type A transitions between state A defined by "OFF · ON" and state B defined by "ON · OFF". In addition, Type B transitions between state B defined by "OFF · ON" and state C defined by Γ ON · OFF ". At this time, due to the response characteristics of the liquid crystal described with reference to FIG. 51 and FIG. 52, during the change of the state Aθ state B in Type A, two liquid crystal layers are temporarily in a voltage application state ("ON · ON" state) temporarily. . Similarly, during the change between Type B &lt; = &gt; C in Type B, two liquid crystal layers are temporarily in a state of voltage application ("ON · ON" state) temporarily. As shown by the thick arrow in Figure 56, "ON · ON" defines the state C in Type A, and -74- This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 1227338 A7 B7 V.

Type B中定義狀態B。因此,Type A在進行狀態A&lt;=&gt;狀態B 的變化過程中,會暫時性的顯示有狀態A及B以外之狀態C 的子幀圖像,導致顯示品質惡化。另外,Type B在進行狀 態BoC間的變化過程中,雖會暫時性的顯示有狀態B的子 幀圖像,不過由於其在狀態Bo狀態C之變化的稍後產生, 因此並未顯示其他狀態的子幀圖像。 爲解決Type A的上述問題,於使其自狀態A轉變成狀態 B,或使其自狀態B轉變成狀態A時,若能以Γ OFF · OFF」達成狀態B時,即可防止狀態C過渡性的產生。 其次,考慮自狀態C轉變成狀態B。此時,考慮自 「ΟΝ · ON」轉變成「ON · OFF」,與自「ON · ON」轉 變成「OFF · OFF」。若考慮兩液晶層的應答特性差,則 通常宜僅改變對其中一個液晶層的施加電壓狀態。因而, 宜選擇自「ΟΝ · ON」轉變成「ON · OFF」。但是,欲以 「ON · OFF」達成狀態B時,自狀態B轉移至狀態A時會發 生上述問題。因此,自狀態C轉變成狀態B時,若再轉變成 狀態A,除以Γ OFF · OFF」達成狀態B,若狀態B以後再 度回到狀態C,則宜以「ON · OFF」達成狀態B。藉此可 以將轉移過程中的畫質惡化抑制在最低限度。 於Type B中,狀態B被Γ OFF · ON」定義時,在自狀態B 改變成狀態C,或自狀態C改變成狀態B的過程中,與Type A同樣的有「ON · ON」的狀態。-但是,如圖5 6所示,因 「ΟΝ · ON」的狀態,狀態B被達成,所以不產生如Type A 時的畫質惡化。因而採用Type B的組成時,在任何轉移過 -75- 本紙張尺度適用中國國家標準(CNS) A4規格(210 X 297公釐) 1227338State B is defined in Type B. Therefore, in the process of changing the state A &lt; = &gt; state B, Type A will temporarily display the sub-frame images of the state C other than the states A and B, resulting in deterioration of display quality. In addition, while Type B is changing between states BoC, it will temporarily display the sub-frame image of state B. However, since it is generated later in the change of state Bo state C, no other states are displayed. Sub-frame image. In order to solve the above-mentioned problems of Type A, when transitioning from state A to state B, or from state B to state A, if state B can be achieved with Γ OFF · OFF ", state C transition can be prevented Sexuality. Second, consider the transition from state C to state B. At this time, consider changing from "ON · ON" to "ON · OFF" and changing from "ON · ON" to "OFF · OFF". Considering the poor response characteristics of the two liquid crystal layers, it is generally desirable to change the state of the voltage applied to only one of the liquid crystal layers. Therefore, you should choose to change from "ON · ON" to "ON · OFF". However, if you want to achieve state B with "ON · OFF", the above problem occurs when you transition from state B to state A. Therefore, when transitioning from state C to state B, if transitioning to state A again, divide by Γ OFF · OFF "to reach state B. If state B returns to state C again later, it is appropriate to reach state B with" ON · OFF " . This can minimize the deterioration of image quality during the transfer process. In Type B, when state B is defined by Γ OFF · ON, during the process of changing from state B to state C, or from state C to state B, there is an "ON · ON" state similar to Type A. . -However, as shown in FIG. 56, the state B is achieved due to the “ON • ON” state, so that the image quality deterioration in the case of Type A does not occur. Therefore, when using the composition of Type B, after any transfer -75- This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 1227338

If the image moving element shown in FIG. 53 has a birefringent crystal plate g3 having an incident light end and a birefringent crystal plate g4 having an outgoing end, When the horse has a relationship between positive birefringence and negative birefringence, yp A can be achieved, that is, as shown in FIG. 59, the direction of light movement is at the light entrance end (left ⑷ and light When the emitting ends (the right side in the figure) are the same, it is only necessary to maintain a 90-degree relationship between the direction of polarization of the light moving at the light emitting end and the light and line moving at the light emitting end. The crystal plate §3 and the crystal plate first enter the direction of j and the direction of the light exit end, T reaches B. In addition, the states A to c of FIG. 55 in which the j state is always applied correspond to the sub-planes on the projected scene The moving position of the image above and below. _ (16th Embodiment) A kappa-shaped image moving element has two elements shown in Fig.%, And these two elements can be obtained by a configuration as shown in FIG. 54. The image moving element is similar to the image moving element of the fifteenth embodiment in that the image moving direction is determined by applying 0N · ff to each liquid crystal layer. The features of this embodiment will be described below with reference to FIGS. 57 and 58. ^ 7 mold soil display tf applies a voltage to the liquid crystal layer at the light emitting end and the light emitting end. For example, there are two states of advancing on the liquid crystal layer of the light emitting end: or no voltage is applied, and from these states, the state of subdividing the state of applying a voltage to the liquid crystal layer of the light emitting end is determined by. Here, the change of the applied voltage state of the two liquid crystal layers as shown in FIG. 52 is shown in thick front in FIG. In addition, during the change in the state of applying voltage to the two liquid crystal layers, the state of "0N · ⑽" occurs in the material properties, which is shown by thick arrows in Fig. 1227338 A7-—_B7 V. Description of the invention (74) 58. As can be seen from FIG. 57 and FIG. 58, in the present embodiment, there is no composition that temporarily changes during the state transition process when the structure… B is adopted. That is, by adopting the structure of Type B, it is possible to prevent other states from appearing during the transfer process, and to prevent the deterioration of the image quality. Secondly, the amount of movement of the sub-frame image is reviewed. As described above, when the response speed of the display panel is slow, a time deviation occurs between the image movement and the display image switching. When such a time offset occurs, the image is displayed double on the projected surface. If it is the sub-set 1A of FIG. 43, the image is sequentially moved in the + y direction one pixel by one pixel, and the image moved by only one pixel portion in the + y direction is displayed only in response to poor response. In addition, if it is the subset 1B of FIG. 43, an image shifted by only one pixel in the -y direction is repeatedly displayed. That is, the contour blur of the image occurs over a region of about 1 pixel. In addition, the factor sets 2A, 2B, 3A, and 3B include image movements of two pixels, so the images of two pixel portion movements are repeatedly displayed, respectively. As a result, the blur of the outline is observed on the area of two pixels. Even if the image between two sub-sets is moved between sub-sets, the same contour blur will occur. In order to suppress this kind of contour blurring, it is advisable to minimize the amount of movement between the images of the children in the continuous display. In addition, in order to solve the above-mentioned problems caused by the line of sight moving direction and speed being roughly consistent with the moving direction and moving speed of the sub-frame image, 'the number of moving positions including one cycle of the moving pattern should be increased by 0 __- 77 · This paper Standards apply to Chinese National Standard (CNS) A4 (210 X 297 mm) 1227338 A7

Description of invention (76) status. (17th embodiment) The projection-type image display device of this embodiment basically has the same structure as that of the first embodiment, and the main difference is that it uses a moving pattern suitable for obtaining a sharper image of a sub-frame image. Therefore, only the differences are explained below. a The first embodiment, as shown in FIG. 12, has three sub-frame images constituting the η + ι (η is a positive integer) frame image, the direction in which it moves and the η-th frame image. The moving direction of the sub-frame image is the same, but in this embodiment, the moving pattern of the sub-frame image is the same as that of the thirteenth embodiment, and the six sub-frame images are used as one cycle. In the thirteenth embodiment, a sub-set 1A and a sub-set CU are combined as shown in Fig. 44 to form a moving pattern of the i period. Therefore, the} period of the movement pattern includes two pixel part movements (twice in the + y direction and · γ direction). In this embodiment, the moving pattern shown in FIG. 62 is used. In one cycle of the moving pattern, six sub-frame images are composed of a pattern that moves four positions on the same straight line. In addition, the size of each movement is 丨 pixel portions. The moving pattern shown in FIG. 62 is equivalent to the private moving pattern in FIG. 44 in the corresponding Fourier space. Therefore, the “partial spectrum” of the moving pattern shown in FIG. 62 is the same as that shown in FIG. 42 (b). That is, this embodiment can obtain the effects of the thirteenth embodiment. Furthermore, this embodiment also The effect of halving the outline color from ± 2 pixels to 1 pixel can be obtained.

Description of the invention (77). This image moving element includes a glass plate 22e having transparent areas A to F. The glass material only uses cheap bk7 glass. The thickness of transparent area a is 0.7 mm, the thickness of transparent areas B and F is 1.4 mm, the thickness of transparent areas c and E is 2.1 mm, and the thickness of transparent area D is 2.8 mm. . The refractive index of each transparent region was 1.5 2. The optical axis of the main surface of the disc-shaped glass plate 22e having such a structure was 83.8. Angle. Therefore, the time of the transversal optical path of each transparent region is synchronized with the time of switching to the corresponding sub-frame, and the glass plate 22e is rotated. As a result, the optical path of the transparent region B moves only 2 6 · 0 am to the transparent regions A and F ', and the transparent region c and E moves to the transparent regions B and F, and the optical path moves only 2 6 · 0 &quot; m, the transparent region D For the transparent areas C and E ', the optical path is moved only by 2 6 · 0 # ~ m. The transparent area A corresponds to, for example, the first sub-frame shown in FIG. 44. At this time, the transparent area B corresponds to the next sub-frame, and the transparent area c also corresponds sequentially in the future. Of course, the image display device may use the image moving device described in the other embodiments. In this embodiment, the pixel arrangement of FIG. 46 is adopted as the pixel arrangement of the image display panel. Similar to the thirteenth embodiment, although the line-of-sight movement is roughly consistent with the sub-frame image movement, the pixel arrangement of the image display panel can be recognized, but it has less adverse effect on the image quality. Adopting a projection-type image display device that is inherently resentful, the image display panel using an achromatic filter also generates three child images during each period, and these images are optically moved, Compared with the single-plate projection image display device using the previous color filter, it can be substantially -80- This paper size applies the Chinese National Standard (CNS) A4 specification (210X 297 mm) Ϊ227338 A7 B7

Description of the invention (Improve the light utilization rate, and can reach 3 times the resolution. Of course, it is also possible to generate 2 sub-frame images during each frame, so that these images are optically moved. In the center, the right stem movement is not smooth, but because the sub-frame switching rate in this part is slow, the LCD fully responds and can get better penetration. Also, it can suppress the gap between image movement and sub-frame switching. The image contour caused by the time deviation caused by color mixing within a pixel portion. (18th embodiment) The projection type image display device, which has always been shaped, basically has the same implementation as the 17th embodiment. The structure with the same shape is mainly different in the moving pattern of the sub-frame image. Therefore, only the differences will be described below. In the 17th embodiment, as shown in FIG. 62, one period of the moving pattern of the sub-frame image is 6 The sub-frame image is composed, and this embodiment is shown in the figure. As shown, the period of the moving pattern of the sub-frame image is composed of 2 sub-frame images. The Fourier space state of the moving pattern in FIG. 63 and FIG. 62 Fu ^ ye space of moving pattern Compared with the state, its local points are more scattered. Therefore, compared with the 17th embodiment, this embodiment is less likely to cause the above-mentioned phenomenon due to a specific line of sight movement speed. The movement pattern of the sub-frame image used in this embodiment, Since a pattern that does not move between subframes must be from an even subframe to an odd subframe, it may be composed of 2 subframes or 1 or 3 subframes. An image suitable for this embodiment An example of a moving element is shown in Figure 50. The moving element is equipped with a broken glass plate 22k, which has transparent areas A to L. The glass material uses only cheap BK7 glass, and the thickness of the transparent area A and L is -81- This paper size is applicable China National Standard (CNS) A4 specification (210X297 mm) 1227338 A7 _______ B7 V. Description of the invention (79) 0.7 mm, thickness of transparent area B and B, D, I, K is 1.4 mm, transparent area C, E, That is, the thickness of J is 2.1 mm, the thickness of transparent area F, and G is 2.8 mm. The refractive index of each transparent area is 1.52. The main surface of the disc-shaped glass plate 22k of this structure is 83.8 to the optical axis. Angle. Therefore, make each through The time of the cross-section of the area is synchronized with the time of switching to the corresponding sub-frame, and the glass plate is rotated 22k. With this, the transparent areas B, D, I, and K are transparent to the transparent areas A and L, and the optical distance is only 26.0 am, transparent. Areas C, E, Η, and J are transparent areas b, d, I, and K, and the optical path is shifted by only 26.0 // m, and transparent areas F and G are through the transparent areas C, E, Η, and J, and the optical path are moved by only 2 6.0. am. Transparent area A corresponds, for example, to the first sub-frame shown in FIG. 49. At this time, transparent area B corresponds to the next sub-frame, and transparent area c also corresponds sequentially. (The second modified example of the image moving element ) Next, another modified example of the image moving element will be described. As described above, the image moving element having a liquid crystal layer is an image moving element which is also suitable for an image display panel of a uniform writing method of a screen and an image display panel of a line scanning method. When the position of the sub-frame image is moved at three places on the same straight line in the projected plane, as described above, only two image moving elements need to be arranged directly on the optical axis. Just fine. In addition, when the positions of the sub-frame images are moved around on the same straight line in the projection plane, it is only necessary to set the movement amounts of the two image moving elements to be different. -8 2-This paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) 1227338 A7 B7 V. Description of the invention (80) The driving method of this type of image moving element will be described below. (19th Embodiment) The image moving element according to this embodiment can move the position of a sub-frame image on a same line in the projected plane, one pixel at a time, and is suitable for achieving the movement of FIGS. 62 and 64. pattern. This image moving element has two elements shown in FIG. 32 (or FIG. 33), which can be obtained by arranging the two elements in series on the optical path as shown in FIG. 53 and changing the amount of each image movement. In this embodiment, since the crystal plate g3 and the crystal plate g4 having birefringence are used to constitute the image moving element, the amount of image movement can be changed by changing the thickness of these crystal plates. With this image moving element, by placing two or more liquid crystal layers on the light entrance end and the light exit end of the optical path in a state of applying a voltage, four different positions on the projected surface can be selected. The four different positions selected are the voltage applied state (ON / OFF) to the first liquid crystal layer (light emitting end) and the voltage applied state (0N / OFF). The movement state at this time varies depending on whether the amount of image movement at the light entrance end is larger or smaller than the amount of image movement at the light exit end. When the amount of image movement at the light emitting end is relatively large, as shown in Fig. 65, and when the amount of image movement at the light emitting end is relatively large, as shown in Fig. 66. The models in Fig. 65 and Fig. 66 show changes in the state of applying a voltage to the liquid crystal layer at the light entrance end and the light exit end. For example, there are two states in which a voltage is applied or not applied to the liquid crystal layer at the light input end, and the states are further subdivided by continuing to apply a voltage state to the liquid crystal layer at the light output end. At this time, because the light input end is in a state of voltage application, it enters the light output end. -83- The paper size is in accordance with the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 1227338 A7 B7 V. Description of the invention (81) The direction of the plane of polarization of the light of the liquid crystal layer changes by 90 °. Therefore, the state of the voltage applied to the light emitting end is changed in exactly the opposite relation with the state of the voltage applied to the light incident end. Therefore, the state changes of the composition of the voltage-applied end and the light-exited end are the two compositions shown above and below each of FIG. 65 and FIG. 66. The above two components are also referred to herein as "Type A" and "Type B". Therefore, the positions of the four different sub-frame images are represented by states A, B, C, and D. In addition, in order to indicate the voltage application state of the two liquid crystals, if the liquid crystal application voltage state of the light input terminal is ON and the voltage output state of the light output terminal is OFF, it is noted as Γ ON · OFF ". At this time, "-OFF · ON" of Type A in Fig. 65 is state A, "OFF · OFF" is state B, "ON · OFF" is state C, and "ON · ON" is state D. In addition, Γ OFF · OFF of TypeB is state A, "OFF · ON" is state B, "ON · ON" is state C, and "ON · OFF" is state D. In addition, states A, B, C, and D may also correspond to any of four different positions on the same plane of the projected surface. Figure 6-6 can also be considered the same. Consider the state transition from "ON · OFF" to "OFF · ON", or the state transition from "OFF · ON" to Γ ON · OFF ". In the example in Fig. 65, the state changes from "ON · OFF" to "OFF · ON", or from "OFF · ON" to Γ ON · OFF ", corresponding to the change of state Ao and state C in Type A. , In Type B corresponds to the change in state Bo state D. Similarly, in the example in FIG. 66, the above-mentioned state change is corresponding to the change of state A «state B in Type A, and -84 in Type B.

From the above investigation, it can be seen that in the example of FIG. 65, the state is changed from "On · OFF" to "r0FF · 0N", or the status from "〇ff · On" to "ON · OFF", and two pixels are performed. Part of the movement. In addition, in the example of Figure ^, the state is changed from ΓΟΝ · 0FF "to" 〇FF · ON ", and the state is changed from" OFF · ON "to" 〇Ν · 〇FF ", so that one image ^ is moved. 'Because the image movement amount of the movement patterns of FIG. 62 and FIG. 64 is i pixel portion, the structure of FIG. 65 does not generate a state from "ON. FF" to "OFF. ON", and the status from "〇. "FF. ON" turns into "ON · OFF". Therefore, problems caused by the slow response of the image element can be avoided. Using the image moving element shown in FIG. 53, if the crystal plate g3 having birefringence at the light entrance end and the crystal plate having birefringence at the exit end are related to each other, the relationship is positive birefringence and negative Type A can be achieved when the birefringence relationship is reached. That is, as shown in FIG. 59, when the light moving direction is the same at the light entrance end (left side in the figure) and the light exit end (right side in the figure), it is only necessary to make the light moving at the light entrance end and the light The polarization direction of the light moving at the exit end can be maintained in a 9 &quot; different relationship. In addition, when the crystal plate g3 and the crystal plate g4 are aligned in the directions of the light entrance end and the light exit end, it can be achieved ... B 〇 Furthermore, if the thickness of the crystal plates g3 and g4 is 2 ··}, Then the image movement amount of each image movement t1 is 2 ·· i. In this way, the moving positions A, B, C, and D of Figure 65 and Figure 66 are equally spaced, and can be shifted by a pixel pitch of -85. V. Description of the invention (83) Motion 0 (20th embodiment) The image moving element of this embodiment has the same two components as shown in FIG. 36 as in the 16th embodiment. Obtained with the configuration shown in Figure 54. This image moving element is similar to the 15th type of image moving element in that it determines the image moving direction by turning ON and OFF a voltage to each liquid crystal layer. The features of this embodiment will be described below with reference to Figs. 67 and 68. Fig. 67 is a model showing the state change of the voltage applied to the liquid crystal layer at the light input end and the light output end. For example, there are two states in which a voltage is applied or not applied to the liquid crystal layer at the light input end, and then these states are determined to be subdivided by continuing to apply a voltage to the liquid crystal layer at the light output end. At this time, it is also considered to change from "ON · OFF" to Γ OFF · ON ", or the state from" OFF · ON "to Γ ON · OFF". In the example in FIG. 67, the state changes from "ON · OFF" to Γ OFF · ON ", or from" OFF · ON "to Γ ON · OFF", resulting in a change in state Bo state C in Type A. A change in state A &lt; = &gt; state D occurs in Type B. Similarly, in the example shown in FIG. 68, a change in state 6 &lt; = &gt; state C occurs in Type A and a change in state A &lt; = &gt; state D occurs in Type B by the state change described above. As can be seen from the above, in the examples of FIGS. 67 and 68, in Type A, the movement of one pixel portion causes the state to change from "ON · _OFF" to Γ OFF · ON ", or the state from" OFF · ON "to Γ ON · OFF ", but in Type B, it occurs only when moving three pixels. -86- This paper size applies the Chinese National Standard (CNS) A4 specification (210 X 297 mm) 1227338 A7 B7 5. Description of the invention (84) The state changes from "ON · OFF" to "OFF · ON", or the state changes from "OFF · ON" to "ON · OFF". When the moving patterns in Fig. 62 and Fig. 64 are used, since the moving amount of the image is one pixel portion, if the structure of Type B is used, other states can be prevented during the transfer process, and the deterioration of image quality can be avoided. The foregoing has described various embodiments of the present invention with respect to a projection-type image display device using a liquid crystal display element (LCD) as an image display panel, but the present invention is not limited thereto. The present invention can also be applied to a projection type image display device using a display element other than a liquid crystal display element, such as a digital micromirror device (DMD), on an image display panel. -In addition, the present invention is also applicable to a direct-view image display device. At this time, an image display panel of a full color display type using a color filter may be used. A general direct-view type device that does not use an optical system for imaging does not require a projected surface such as a screen. However, in a direct-view type device that uses glasses to observe an image, the retina of the eye functions as the projected surface of the image. Furthermore, the present invention can also be applied to a direct-view type or projection-type image display device that does not require a special light source and uses a self-emission type image display element as an image display panel. In addition, the above description is based on an example in which an optical path is periodically changed by a refractive member to describe an embodiment of an image moving element. However, at least a part of a light source or an optical system may be moved to change the optical path. For example, by vibrating the projection lens tf shown in FIG. 1, the image can be moved.

This embodiment also mainly includes an image signal processing circuit 100, an illumination optical system (light source, etc.) 102, an image-display panel (liquid crystal display element) 104, an image moving element 106, and an image moving element control circuit. 108 and the projection lens 110. Since the illumination optical system 102, the image display panel 104, the image moving element 106, and the projection lens 110 have already been described, the following description will focus on the constituent elements of the image signal processing circuit 100 and the image moving element control circuit 108. The relationship is the same as that of Embodiment 11. The image signal processing circuit 100 of this embodiment includes an input signal selection circuit 120, an image demodulation circuit 122, a Y / C separation circuit 124, a concealment circuit 126, a frame rate conversion circuit 128, a system control circuit 132, and a color signal selection circuit. 1340, and frame memory circuit 1300.

Description of the invention (87) (Mapping) On the frame memory circuit 1300, each sub-frame image is stored in the corresponding frame memory. ? The data of the sub-frame images that have been recalled in each frame memory are sequentially read out. As described above, when a frame is composed of two sub-frames, if the method of the first embodiment is adopted, since all the shell materials of each frame are stored regardless of the number of sub-frames contained in the frame, it is necessary to use each color signal. Total 3 frame memories. However, in this embodiment, since the sub-frame image is directly mapped to the frame memory, it is only necessary to store necessary sub-frame image data in the frame memory. Therefore, when one frame is composed of two sub-frames, there is an advantage that the number of frame memories or the memory capacity is two-thirds of the second embodiment. (Twenty-second embodiment) _ Next, an image moving element having at least a combination of a liquid crystal element and a birefringent element is taken as an example to describe a preferred moving direction of an image. When the single-plate projection display device using the micro lens array shown in FIG. 2 is used, the angles at which the colors in the RGB enter the pixel area are different. Therefore, each color of RGB is emitted from the display panel, and the angle of light rays entering the birefringent element in the image moving element is also different. The birefringent element has an inclined optical axis from the light incident surface, and light rays perpendicularly incident on the light incident surface move in a direction parallel to a plane (main section) including the optical axis and the incident optical axis. At this time, the image moving direction is parallel to the main section of the birefringent element. However, when the incident angle of each RGB color to the incident surface of the birefringent element is different, the direction or amount of light movement changes. First, consider when the RGB color separation direction is consistent with the image movement direction. At this time, the main section of the birefringent element is caused by the rays of each color of RGB in parallel. —-90- I Paper G applies the Chinese National Standard (CNS) A4 specification (21G X 297 public love)
