Description
本發明是有關於一種顯示單元及其裝置，特別是有關於一種裸眼3D顯示像素單元及具有2D/3D模式同時間不同區顯示或全屏相互切換功能的顯示裝置。The present invention relates to a display unit and a device thereof, and more particularly to a naked-eye 3D display pixel unit and a display device having a 2D/3D mode simultaneous different area display or full screen mutual switching function.
由於一般人左眼與右眼瞳孔相距約為6.0 cm ~ 7.0 cm，導致兩眼視網膜所接收到的影像訊息因為視角差異而有些微不同，而人腦有融合兩個不同視角影像訊息產生深度知覺之功能，故人眼觀看物體時會形成立體視覺效果。Because the average left eye and the right eye pupil are about 6.0 cm ~ 7.0 cm apart, the image information received by the two retinas is slightly different because of the difference in viewing angle, and the human brain has two different perspective images to generate depth perception. Function, so the human eye will form a stereoscopic effect when viewing the object.
在立體顯示技術領域中，習知技術主要分為：眼鏡式以及裸眼式3D顯示技術。而裸眼式3D顯示技術又以柱鏡光柵（lenticular lens）和視差光柵（parallax barrier）為大多數顯示產品所採用。In the field of stereoscopic display technology, the prior art is mainly divided into: glasses type and naked eye type 3D display technology. The naked-eye 3D display technology is also used in most display products with a lenticular lens and a parallax barrier.
一般而言，裸眼3D顯示技術需搭配液晶顯示面板呈現立體圖像，不僅製程繁複、成本高，且光柵與液晶面板的像素對準和組裝精准度要求極高。尤其對大尺寸的顯示屏幕而言，搭配光柵的裸眼3D顯示產品，不良率和製造組裝成本都相對高出許多，且因為液晶面板和光柵透鏡的製程有其面積尺寸的限制因素，不適合大面積顯示產品的應用。In general, the naked-eye 3D display technology needs to be presented with a liquid crystal display panel to present a stereoscopic image, which is not only complicated in process, high in cost, but also requires high precision in pixel alignment and assembly precision of the grating and the liquid crystal panel. Especially for large-size display screens, the naked-eye 3D display products with gratings are relatively high in defect rate and manufacturing assembly cost, and because the process of liquid crystal panel and grating lens has limitations in area size, it is not suitable for large areas. Display the application of the product.
因液晶面板前裝置光柵透鏡是為實現裸眼3D，因此2D的影像或文字便受到影響。現有切換2D/3D顯示模式的習知技術，大多運用光電元件或移動光學器件來實現，但並未普遍運用於現今產品中。同樣，LED 顯示屏幕若利用與液晶面板前面加裝光柵透鏡如柱鏡光柵和視差光柵等相似方法實現2D/3D顯示模式切換也會出現類似的缺點。Since the grating lens in front of the liquid crystal panel is for the naked eye 3D, the 2D image or text is affected. Existing conventional techniques for switching 2D/3D display modes are mostly implemented using optoelectronic components or moving optics, but are not commonly used in today's products. Similarly, LED display screens have similar disadvantages when using 2D/3D display mode switching by using a grating lens such as a lenticular grating and a parallax barrier in front of the liquid crystal panel.
在CN203930226U利用一種裸眼3D顯示像素單元組成多視圖裸眼3D顯示裝置。其光學封裝體包含光學導引區域及混光區域，該混光區域能夠將該子像素單元發出的光透過反射、折射或全反射作用于該光學封裝體內混合，並且導引至該光學導引區域，該光學導引區域與該子像素單元相互對應，該光學導引區域可導引子像素單元發出的光使其偏轉匯聚至不同方向，或經由擋板遮擋作用，導引出該光學封裝體外，使像素單元有效發出左、右眼視差圖像，後至觀看者的兩眼，讓人腦感知該視差圖像後並融合成立體圖像。In CN203930226U, a naked-eye 3D display pixel unit is used to form a multi-view naked-eye 3D display device. The optical package includes an optical guiding region and a light mixing region, wherein the light mixing region can transmit light emitted by the sub-pixel unit to the optical package through reflection, refraction or total reflection, and guide to the optical guide. a region, the optical guiding region corresponding to the sub-pixel unit, the optical guiding region guiding the light emitted by the sub-pixel unit to deflect the beam to different directions, or guiding the optical package through the baffle blocking function In vitro, the pixel unit is effectively caused to emit left and right eye parallax images, and then to the two eyes of the viewer, the brain perceives the parallax image and merges to form a volume image.
因為將裸眼3D顯示像素單元最小化到零件級，故可以依據用途和室內/戶外安裝現場需要，將3D顯示像素單元縱橫排列組成顯示單元模組或箱體，並將多個顯示單元模組拼接成不同面積尺寸、外凸弧形、內凹弧形或自由曲面形狀的大型面積顯示屏幕，無須在顯示屏幕前平行裝設光學透鏡、完全不受透鏡面積尺寸限制，自由擴展無縫拼接成符合不同形狀與大小需要的顯示屏幕。Because the naked-eye 3D display pixel unit is minimized to the part level, the 3D display pixel unit can be vertically and horizontally arranged to form a display unit module or a box according to the purpose and indoor/outdoor installation site requirements, and multiple display unit modules can be spliced. Large-area display screens with different area sizes, convex curved shapes, concave curved shapes or free-form surface shapes, without the need to install optical lenses in parallel in front of the display screen, completely independent of the lens area size, freely expand seamlessly into a matching Display screens that are required for different shapes and sizes.
另可將裸眼3D顯示像素單元搭配全彩LED，分別行列相鄰交替排布在電路基板上組成顯示單元模組，並組裝成大面積屏幕。此系統便可以經由裸眼3D顯示像素單元和全彩LED交互點亮或滅燈，切換2D和3D圖像顯示模式。當全彩LED點亮時裸眼3D顯示像素單元熄滅，此時屏幕顯示2D圖像。反之，當裸眼3D顯示像素單元點亮時，此時屏幕顯示3D圖像。In addition, the naked-eye 3D display pixel unit is matched with the full-color LED, and the rows and columns are alternately arranged adjacent to each other on the circuit substrate to form a display unit module, and assembled into a large-area screen. The system can alternately turn on or off the light through the naked-eye 3D display pixel unit and the full-color LED to switch the 2D and 3D image display modes. When the full-color LED is lit, the naked-eye 3D display pixel unit is turned off, and the screen displays a 2D image. On the contrary, when the naked-eye 3D display pixel unit is lit, the screen displays a 3D image at this time.
因此，可以同一時間在顯示屏幕全彩LED區域播放2D內容，而在裸眼3D顯示像素單元區域播放裸眼3D內容。或依據節目內容全屏幕實時切換2D/3D顯示模式，此種裝置需要裸眼3D顯示像素單元和LED兩種顯示器件相鄰搭配組成，但控制兩相鄰不同元件之亮度和色彩的一致性有其困難，另因裸眼3D顯示像素單元和LED兩者相鄰排佈各自分別顯示3D和2D訊息，結果將導致2D和3D圖像分辨率的降低。Therefore, the 2D content can be played in the full-color LED area of the display screen at the same time, and the naked-eye 3D content can be played in the naked-eye 3D display pixel unit area. Or switch the 2D/3D display mode in real time according to the content of the program. This device requires the naked eye 3D display pixel unit and the LED display device to be adjacent to each other, but controls the brightness and color consistency of two adjacent different components. Difficulty, because the naked-eye 3D display pixel unit and the LED are arranged adjacent to each other to display 3D and 2D messages, respectively, and the result will be a reduction in 2D and 3D image resolution.
有鑑於此，如何使一種裸眼3D顯示像素單元同時具備發送2D訊息和3D視差圖像，並可以極小的間距均勻排佈組成的高解析度的大面積顯示裝置，使其具備2D或3D圖像隨播放，內容顯示動態相互功能切換，以及具備2D和3D內容同一時間在顯示屏幕不同區域顯示之功能。此種功能在混合撥放各種2D或3D視頻內容時其必要性，也是現今眼鏡式3D何其他習知立體顯示技術不足之處。In view of this, how to make a naked-eye 3D display pixel unit have a high-resolution large-area display device that can simultaneously transmit a 2D message and a 3D parallax image, and can be evenly arranged at a very small pitch, so as to have a 2D or 3D image. With playback, the content display dynamic mutual function switching, and the function of displaying 2D and 3D content in different areas of the display screen at the same time. This kind of function is necessary when mixing and placing various 2D or 3D video content, and it is also a shortcoming of today's glasses-type 3D and other conventional stereo display technologies.
有鑑於上述習知技術待解決之問題，本發明的目的在於提供一種裸眼3D顯示像素單元及具有2D和3D內容可以同一時間不同區域顯示或全屏相互切換播放功能的顯示裝置。In view of the above-mentioned problems to be solved by the prior art, an object of the present invention is to provide a naked-eye 3D display pixel unit and a display device having a 2D and 3D content display at different times and a full-screen mutual playback function.

The unit 110c includes a substrate 111, a first electrode layer 112, a first doped layer 113, a second doped layer 114, and a plurality of second electrode layers 115, respectively.
更詳細地說，第一電極層112設於基板111上，第一摻雜層113設於第一電極層112上，第二摻雜層114設於第一摻雜層113上，複數個第二電極層115分別相對且不連接地設於第二摻雜層114上。In more detail, the first electrode layer 112 is disposed on the substrate 111, the first doped layer 113 is disposed on the first electrode layer 112, and the second doped layer 114 is disposed on the first doped layer 113. The two electrode layers 115 are respectively disposed on the second doping layer 114 oppositely and unconnected.
值得一提的是，於本發明的圖式中第二電極層115之數量係以兩個為例；此外，第一電極層112為N型電極層時，第二電極層115則為P型電極層；反之，若第一電極層112為P型電極層時，第二電極層115則為N型電極層。It is to be noted that, in the drawings of the present invention, the number of the second electrode layers 115 is exemplified by two; in addition, when the first electrode layer 112 is an N-type electrode layer, the second electrode layer 115 is a P-type. The electrode layer; conversely, when the first electrode layer 112 is a P-type electrode layer, the second electrode layer 115 is an N-type electrode layer.
續言之，本發明之裸眼3D顯示像素單元1所包含之光學混光區120設於像素單元110上；而光學導引區130則設於光學混光區120之上；於本發明中，控制電路用以電性連結像素單元110，且依據2D影像訊號或3D影像訊號控制像素單元110投射形成對應之2D影像或3D影像。Continuingly, the optical mixing region 120 included in the pixel-receiving pixel unit 1 of the present invention is disposed on the pixel unit 110; and the optical guiding region 130 is disposed on the optical mixing region 120. In the present invention, The control circuit is configured to electrically connect the pixel unit 110, and control the pixel unit 110 to project a corresponding 2D image or 3D image according to the 2D image signal or the 3D image signal.
進一步地，本發明可以使用微透鏡設計和製造技術將柱鏡光柵、視差光柵或其他光學透鏡設計等應用於光學導引區130中。本實施例中，該光學導引區130以及該光學混光區120可以由不同的材料組合而成，或是由同一種材料一體成形製造而成，可依據製造的製程或視顯示需求效果予以調整和設計。光學導引區130的出光面可以是：平面、斜面、曲面或雙層的組合，如：柱鏡光柵、視差光柵或雙層的透鏡設計等組合結構，用以導引像素單元110所發出的光至不同的方向或經由擋板產生遮擋作用由縫隙中間發出光線。Further, the present invention can apply a lenticular grating, a parallax barrier or other optical lens design, etc., to the optical guiding region 130 using microlens design and fabrication techniques. In this embodiment, the optical guiding area 130 and the optical mixing area 120 may be made of different materials or integrally formed from the same material, and may be processed according to the manufacturing process or the visual display demand effect. Adjustment and design. The light-emitting surface of the optical guiding area 130 may be a combination of a plane, a bevel, a curved surface or a double layer, such as a lenticular grating, a parallax grating or a double-layer lens design, for guiding the pixel unit 110 to emit Light is emitted in different directions or through the baffle to illuminate the middle of the gap.
更詳細地說，當控制電路傳送2D影像訊號至像素單元110時，像素單元110會經由光學混光區120及光學導引區130以直射角度投射光(2D影像訊息)；進而，觀看者之雙眼將接收到像素單元110所投射之2D影像訊息。In more detail, when the control circuit transmits the 2D video signal to the pixel unit 110, the pixel unit 110 projects the light (2D image information) at a direct angle through the optical light mixing area 120 and the optical guiding area 130; Both eyes will receive the 2D image information projected by the pixel unit 110.
值得一提的是，當控制電路傳送3D影像訊號至像素單元110時，控制電路將交替地控制各第二電極層115a、115b與第一電極層112形成對應之電場，以使像素單元110可依時序交錯地以相對之二偏射角度分別投射光(3D影像訊息)，各3D影像訊息分別經由光學混光區120及光學導引區130至觀看者之左眼及右眼，觀看者藉由兩眼視差將3D影像訊息於腦中結合形成為3D影像。It is worth mentioning that when the control circuit transmits the 3D video signal to the pixel unit 110, the control circuit alternately controls the electric fields corresponding to the second electrode layers 115a, 115b and the first electrode layer 112 to make the pixel unit 110 Each of the 3D image information is respectively transmitted to the left eye and the right eye of the viewer via the optical light mixing area 120 and the optical guiding area 130 through the optically mixed light area 120 and the optical guiding area 130, respectively, by the viewer. The 3D image information is combined into the brain by the binocular parallax to form a 3D image.
更進一步地說，當控制電路於第一時間點T 1控制第二電極層115a與第一電極層112形成電場後，像素單元110可依對應第二電極層115a之偏射角度投射3D影像訊息（如第2圖（a）所示，朝偏左的角度投射3D影像訊息），而當控制電路於第二時間點T 2控制另一個第二電極層115b與第一電極層112形成電場後，像素單元110便可依對應第二電極層115b之另一個偏射角度投射3D影像訊息（如第2圖（b）所示，朝偏右的角度投射3D影像訊息）。 More particularly, when the control circuit T 1 controls the second electrode layer 115a and the first electrode layer 112 is formed at a first time point of an electric field, the pixel unit 110 corresponding to the second electrode layer to follow the deflection angle of the projected 3D image posts 115a (e.g., FIG. 2 (a), the angle of the projected toward the left 3D video message), and when the control circuit T 2 controlled at a second time point and the another second electrode layer 115b of the first electrode layer 112 is formed an electric field The pixel unit 110 can project a 3D image message according to another deflection angle of the second electrode layer 115b (as shown in FIG. 2(b), project a 3D image message toward a right angle).
承上所述可知，本發明之像素單元110之所以可以在顯示3D影像時依時序交錯地輪流從兩個不同的角度投射3D影像訊息，是因為當其中一個第二電極層115與第一電極層112之間形成電場時，像素單元110之投射角度便會偏向該第二電極層115之方向；因此，僅需藉由控制電路切換不同的第二電極層115與第一電極層112形成電場，便可交錯地以不同角度投射3D影像訊息。As can be seen from the above, the pixel unit 110 of the present invention can alternately project 3D image information from two different angles in a time-interleaved manner when displaying 3D images because one of the second electrode layers 115 and the first electrode When an electric field is formed between the layers 112, the projection angle of the pixel unit 110 is biased toward the second electrode layer 115; therefore, only the second electrode layer 115 and the first electrode layer 112 are switched by the control circuit to form an electric field. , you can interlace 3D image information at different angles.
此外，雖像素單元110在交錯投射3D影像訊息時，就以一偏射角度進行投射，然為使投射3D影像訊息之偏移角度可以再加大，故使得3D影像訊息需進一步通過光學混光區120及光學導引區130，以藉由光學混光區120及光學導引區130加大其偏移角度。In addition, although the pixel unit 110 is projected at a different angle when interlacing the 3D image information, the offset angle of the projected 3D image information can be further increased, so that the 3D image information needs to be further optically mixed. The region 120 and the optical guiding region 130 are used to increase the offset angle thereof by the optical mixing region 120 and the optical guiding region 130.
需說明的是，本發明之像素單元110是經由半導體製程所製成的，而在半導體製程中，第一電極層112及複數個第二電極層115皆是經由打線步驟所形成的。裸眼3D顯示像素單元1可進一步包含有機發光二極體（OLED）或無機發光二極體等，如有機發光材料或III-V族化合物半導體材料等。光學封裝體的材料可包含：聚碳酸酯（PC）、聚甲基丙烯酸甲酯（PMMA）、樹脂（Resin）、矽膠（Silicon）、玻璃、環氧樹脂（Epoxy）等材料，利用熱固化成形或利用紫外光固化成型，且光學封裝體可以為中空或實心結構，或運用芯片級封裝(chip scale packaging)完成。It should be noted that the pixel unit 110 of the present invention is fabricated through a semiconductor process, and in the semiconductor process, the first electrode layer 112 and the plurality of second electrode layers 115 are formed through a wire bonding step. The naked-eye 3D display pixel unit 1 may further include an organic light emitting diode (OLED) or an inorganic light emitting diode or the like, such as an organic light emitting material or a III-V compound semiconductor material or the like. The material of the optical package may include: polycarbonate (PC), polymethyl methacrylate (PMMA), resin (Resin), silicone (Silicon), glass, epoxy (Epoxy) and the like, formed by heat curing. Or by UV curing, and the optical package can be hollow or solid structure, or can be completed by chip scale packaging.
另一方面，當顯示2D影像時，由於所有第二電極層115會同時與第一電極層112形成電場，因此像素單元110之投射角度將不會偏向某一邊，而是以直射的角度投射2D影像訊息。On the other hand, when the 2D image is displayed, since all the second electrode layers 115 simultaneously form an electric field with the first electrode layer 112, the projection angle of the pixel unit 110 will not be biased to one side, but the 2D is projected at a direct angle. Image message.

The difference between the naked-eye 3D display pixel unit 1 and the first embodiment described in the foregoing embodiment is that the naked-eye 3D display pixel unit 1 of the embodiment includes a plurality of pixel units 110.
續言之，上述中本發明之裸眼3D顯示像素單元1所包含之複數個像素單元110又分別包含紅色發光單元110a、綠色發光單元110b及藍色發光單元110c，紅色發光單元110a、綠色發光單元110b及藍色發光單元110c皆分別包含基板111、第一電極層112、第一摻雜層113、第二摻雜層114及複數個第二電極層115。其中，第一電極層112設於基板111上，第一摻雜層113設於第一電極層112上，第二摻雜層114設於第一摻雜層113上，複數個第二電極層115分別相對且不連接地設於第二摻雜層114上。Continuing to say, the plurality of pixel units 110 included in the pixel-receiving 3D display pixel unit 1 of the present invention respectively include a red light emitting unit 110a, a green light emitting unit 110b, and a blue light emitting unit 110c, and the red light emitting unit 110a and the green light emitting unit. Each of the 110b and the blue light emitting units 110c includes a substrate 111, a first electrode layer 112, a first doped layer 113, a second doped layer 114, and a plurality of second electrode layers 115.

續言之，於本發明的圖式中第二電極層115之數量同樣以兩個為例；此外，第一電極層112為N型電極層時，第二電極層115則為P型電極層；反之，若第一電極層112為P型電極層時，第二電極層115則為N型電極層。Continuingly, in the drawings of the present invention, the number of the second electrode layers 115 is also exemplified by two; in addition, when the first electrode layer 112 is an N-type electrode layer, the second electrode layer 115 is a P-type electrode layer. On the other hand, when the first electrode layer 112 is a P-type electrode layer, the second electrode layer 115 is an N-type electrode layer.
而上述中本發明之裸眼3D顯示像素單元1所包含之光學混光區120設於複數個像素單元110上；而光學導引區130則設於光學混光區120之上；於本發明中，控制電路用以電性連結複數個像素單元110，且依據2D影像訊號或3D影像訊號控制複數個像素單元110投射形成對應之複數個2D影像或複數個3D影像。The optical mixing region 120 included in the naked-eye 3D display pixel unit 1 of the present invention is disposed on the plurality of pixel units 110; and the optical guiding region 130 is disposed on the optical mixing region 120. In the present invention, The control circuit is configured to electrically connect the plurality of pixel units 110, and control the plurality of pixel units 110 to project a plurality of corresponding 2D images or a plurality of 3D images according to the 2D image signal or the 3D image signal.
承上述，當控制電路傳送2D影像訊號至複數個像素單元110時，各像素單元110會經由光學混光區120及光學導引區130以直射角度投射光(2D影像訊息)；進而，觀看者之雙眼將可接收到各像素單元110所投射之2D影像訊息，形成2D影像。In the above, when the control circuit transmits the 2D video signal to the plurality of pixel units 110, each of the pixel units 110 projects light (2D image information) at a direct angle through the optical light mixing area 120 and the optical guiding area 130; The two eyes will receive the 2D image information projected by each pixel unit 110 to form a 2D image.
另一方面，當控制電路傳送3D影像訊號至複數個像素單元110時，控制電路將交替地控制各像素單元110之各第二電極層115a、115b與第一電極層112形成對應之電場，以使各像素單元110可依時序交錯地以相對之二偏射角度分別投射光(3D影像訊息)，各像素單元110所投射之各3D影像訊息分別經由光學混光區120及光學導引區130傳至觀看者之左眼及右眼，觀看者藉由兩眼視差將3D影像訊息於腦中結合形成為3D影像。On the other hand, when the control circuit transmits the 3D video signal to the plurality of pixel units 110, the control circuit alternately controls the electric fields corresponding to the second electrode layers 115a and 115b of each of the pixel units 110 to form a corresponding electric field with the first electrode layer 112. Each of the pixel units 110 can respectively project light (3D image information) at a relative two-offset angle, and each of the 3D image information projected by each pixel unit 110 passes through the optical light mixing area 120 and the optical guiding area 130 respectively. Passed to the left and right eyes of the viewer, the viewer combines the 3D image information into the brain to form a 3D image by binocular parallax.
更進一步地說，當控制電路於第一時間點T 1控制各像素單元110之第二電極層115a與第一電極層112形成電場後，各像素單元110可依對應第二電極層115a之偏射角度投射3D影像訊息（如第5圖所示，朝偏左的角度投射3D影像訊息），而當控制電路於第二時間點T 2控制各像素單元110之另一個第二電極層115b與第一電極層112形成電場後，各像素單元110便可依對應第二電極層115b之另一個偏射角度投射3D影像訊息（如第6圖所示，朝偏右的角度投射3D影像訊息）。 More particularly, when the control circuit 1 controls each unit pixel is formed at a first time point T field 110 of the second electrode layer 115a and the first electrode layer 112, each pixel corresponding to the biasing unit 110 to follow the second electrode layer 115a 3D image projected exit angle posts (as shown in Figure 5, the angle of the projected toward the left 3D video message), while when the second control unit control circuit of each pixel at a second time point T 110 of the second electrode layer 115b and the other After the first electrode layer 112 forms an electric field, each pixel unit 110 can project a 3D image message according to another deflection angle of the corresponding second electrode layer 115b (as shown in FIG. 6 , project a 3D image message toward a right angle) .
承上所述可知，本發明之像素單元110之所以可以在顯示3D影像時依時序交錯地輪流從兩個不同的角度投射3D影像訊息，是因為當其中一個第二電極層115與第一電極層112之間形成電場時，像素單元110之投射角度便會偏向該第二電極層115之方向；因此，僅需藉由控制電路切換不同的第二電極層115與第一電極層112形成電場，便可交錯地以不同角度投射3D影像訊息。如第8圖所示，其所示意的是於第一時間點及第二時間點之後，複數個像素單元110所投射之3D影像訊息之呈現，在第一時間點時，複數個像素單元110係同時朝左投射3D影像訊息，且如同中所示，像素單元110之數量為三個，進而在同一時間點中，裸眼3D顯示像素單元1可同時投射三個3D影像訊息；反之，於第二時間點時，複數個像素單元110便同時朝右投射而產生三個3D影像訊息。As can be seen from the above, the pixel unit 110 of the present invention can alternately project 3D image information from two different angles in a time-interleaved manner when displaying 3D images because one of the second electrode layers 115 and the first electrode When an electric field is formed between the layers 112, the projection angle of the pixel unit 110 is biased toward the second electrode layer 115; therefore, only the second electrode layer 115 and the first electrode layer 112 are switched by the control circuit to form an electric field. , you can interlace 3D image information at different angles. As shown in FIG. 8, the first embodiment shows the presentation of the 3D image information projected by the plurality of pixel units 110 after the first time point and the second time point. At the first time point, the plurality of pixel units 110 The 3D image information is projected to the left at the same time, and as shown in the figure, the number of the pixel units 110 is three, and in the same time point, the naked eye 3D display pixel unit 1 can simultaneously project three 3D image messages; At two time points, a plurality of pixel units 110 are simultaneously projected to the right to generate three 3D image messages.
此外，雖像素單元110在交錯投射3D影像訊息時，就以一偏射角度進行投射，然為使投射3D影像訊息之偏移角度可以再加大，故使得3D影像訊息需進一步通過光學混光區120及光學導引區130，以藉由光學混光區120及光學導引區130加大其偏移角度。因此，配合時序播放控制，請參閱第9圖，本發明可藉由持續快速地改變投射方向，將3D影像訊息投射至下一視區(Viewing zone)，以達到多視點(Multi-view)觀看之功效。In addition, although the pixel unit 110 is projected at a different angle when interlacing the 3D image information, the offset angle of the projected 3D image information can be further increased, so that the 3D image information needs to be further optically mixed. The region 120 and the optical guiding region 130 are used to increase the offset angle thereof by the optical mixing region 120 and the optical guiding region 130. Therefore, in conjunction with the timing playback control, referring to FIG. 9, the present invention can project a 3D image message to a next viewing zone by continuously and rapidly changing the projection direction to achieve multi-view viewing. The effect.
除上前述顯示3D影像之外，當顯示2D影像時，由於各像素單元110之所有第二電極層115會同時與第一電極層112形成電場，因此各像素單元110之投射角度將不會偏向某一邊，而是以直射的方式投射2D影像訊息。In addition to the foregoing display 3D image, when the 2D image is displayed, since all the second electrode layers 115 of each pixel unit 110 simultaneously form an electric field with the first electrode layer 112, the projection angle of each pixel unit 110 will not be biased. On one side, the 2D image message is projected in a direct manner.

承上述，於同一時間中所顯示之影像，顯示屏幕2之一部分區域中之複數個裸眼3D顯示像素單元1可由控制電路控制而投射形成對應2D影像訊號之複數個2D影像，而另一部分區域中之複數個裸眼3D顯示像素單元1則由控制電路控制而投射形成對應3D影像訊號之複數個3D影像。According to the image displayed at the same time, a plurality of naked-eye 3D display pixel units 1 in a partial region of the display screen 2 can be controlled by the control circuit to form a plurality of 2D images corresponding to the 2D image signals, and in another partial region. The plurality of naked-eye 3D display pixel units 1 are controlled by the control circuit to project a plurality of 3D images corresponding to the 3D video signals.
更進一步地， 具有2D/3D模式同時間不同區顯示或全屏相互切換功能的顯示裝置20可連結內容播放裝置3，內容播放裝置3用以接收由內容儲存裝置4所儲存之2D或3D影像資料，並譯碼所接收之2D或3D影像資料以產生多視圖影像訊號，再將多視圖影像訊號傳送至具有2D/3D模式同時間不同區顯示或全屏相互切換功能的顯示裝置20，而由顯示屏幕2投射顯示。Further, the display device 20 having the 2D/3D mode simultaneous different zone display or full screen mutual switching function can be connected to the content playback device 3 for receiving the 2D or 3D image data stored by the content storage device 4. And decoding the received 2D or 3D image data to generate a multi-view image signal, and then transmitting the multi-view image signal to the display device 20 having the 2D/3D mode simultaneous different zone display or full screen mutual switching function, and being displayed by the display device 20 Screen 2 is projected.
續言之，由於各裸眼3D顯示像素單元1可對應不同的影像訊號（2D影像訊號或3D影像訊號），而個別對應投射形成2D影像或3D影像，使得顯示屏幕2上之至少一部分區域可顯示2D影像，並搭配以其他區域顯示3D影像；亦或是，至少一部分區域顯示3D影像，而其他區域顯示2D影像。另，可全區域顯示2D影像或全區域顯示3D影像。In other words, since the naked-eye 3D display pixel unit 1 can correspond to different image signals (2D video signals or 3D video signals), and the corresponding corresponding projections form 2D images or 3D images, at least a part of the area on the display screen 2 can be displayed. 2D image and display 3D images in other areas; or, at least part of the area displays 3D images, while other areas display 2D images. In addition, 2D images can be displayed in all areas or 3D images can be displayed in a full area.
進一步地說，由於各裸眼3D顯示像素單元1皆能切換投射2D或3D影像訊息，因此，本發明裸眼3D顯示像素單元1組成之大面積顯示屏幕便可依據不同2D或3D內容，全屏2D/3D顯示動態相互功能切換，或在顯示屏幕不同區域同一時間分別播放2D及3D內容。不需限定特定區域僅能顯示2D或3D影像，進而大大增加顯示屏幕2切換2D/3D影像及調整變化2D或3D顯示影像區域的彈性，因此，使得節目內容製作更添加多元變化及觀賞性。Further, since each of the naked-eye 3D display pixel units 1 can switch between projecting 2D or 3D image information, the large-area display screen composed of the naked-eye 3D display pixel unit 1 of the present invention can be based on different 2D or 3D content, full-screen 2D/ 3D displays dynamic mutual function switching, or plays 2D and 3D content at the same time in different areas of the display screen. It is not necessary to limit the specific area to display only 2D or 3D images, thereby greatly increasing the flexibility of the display screen 2 to switch 2D/3D images and adjust the 2D or 3D display image areas. Therefore, the program content creation adds multi-variation and viewing.
