偏光眼鏡型立體影像顯示器Polarized glasses type stereoscopic image display

本發明涉及一種立體影像顯示器，尤其涉及一種能夠改善立體影像垂直視角的偏光眼鏡型立體影像顯示器。The present invention relates to a stereoscopic image display, and more particularly to a polarized glasses type stereoscopic image display capable of improving a vertical viewing angle of a stereoscopic image.

立體影像顯示器是藉由利用立體技術或自由立體技術來顯示立體影像。The stereoscopic image display is to display a stereoscopic image by using a stereoscopic technique or an autostereoscopic technique.

所述的立體技術是利用使用者左右眼之間的雙眼視差影像並且具有高立體效果，這種技術包括已經在實際應用中之眼鏡式與裸眼式。在所述的眼鏡式中，所述雙眼視差影像通過改變偏振方向或利用分時方式顯示在一個直接基於視圖的顯示設備上或顯示在投影儀上，然後利用偏光眼鏡或液晶快門眼鏡實現立體的影像。在所述裸眼式中，通常將為了分離所述雙眼視差影像的光軸的光學面板(例如視差屏障等等)設置在顯示螢幕的前面或背面。The stereoscopic technology utilizes binocular parallax images between the left and right eyes of the user and has a high stereoscopic effect, and the technology includes glasses and naked eyes that have been in practical use. In the above-mentioned eyeglass type, the binocular parallax image is displayed on a direct view-based display device or displayed on a projector by changing the polarization direction or using a time-sharing manner, and then realizing the stereoscopic image by using polarized glasses or liquid crystal shutter glasses. Image. In the naked eye type, an optical panel (for example, a parallax barrier or the like) for separating the optical axis of the binocular parallax image is generally disposed on the front or the back of the display screen.

第1圖為顯示先前技術的偏光眼鏡型立體影像顯示器的視圖。Fig. 1 is a view showing a prior art polarized glasses type stereoscopic image display.

參考第1圖，該眼鏡型立體影像顯示器1包括顯示面板以及與結合到該顯示面板的圖案相位差膜17。Referring to Fig. 1, the glasses-type stereoscopic image display 1 includes a display panel and a pattern retardation film 17 coupled to the display panel.

所述顯示面板包括薄膜電晶體陣列基板10、包括濾色片13及黑色矩陣14的濾色片基板12、形成在薄膜電晶體陣列基板10與濾色片基板12之間的液晶層15、貼附在薄膜電晶體陣列基板10底部的第二偏光板16b以及貼附在濾色片基板12頂部的第一偏光板16a。The display panel includes a thin film transistor array substrate 10, a color filter substrate 12 including a color filter 13 and a black matrix 14, a liquid crystal layer 15 formed between the thin film transistor array substrate 10 and the color filter substrate 12, and a sticker. A second polarizing plate 16b attached to the bottom of the thin film transistor array substrate 10 and a first polarizing plate 16a attached to the top of the color filter substrate 12 are attached.

圖案相位差膜17包括選擇性地只傳送第一偏振光的第一相位差膜圖案以及選擇性地只傳送第二偏振光的第二相位差膜圖案，並且圖案相位差膜17貼附在第一偏光板16a上。第一相位差膜圖案與第二相位差膜圖案逐行交替地形成。表面處理保護膜18可貼附在圖案相位差膜17上。The pattern retardation film 17 includes a first retardation film pattern that selectively transmits only the first polarized light and a second retardation film pattern that selectively transmits only the second polarized light, and the pattern retardation film 17 is attached to the first A polarizing plate 16a. The first retardation film pattern and the second retardation film pattern are alternately formed row by row. The surface treatment protective film 18 can be attached to the pattern retardation film 17.

這種類型的立體影像顯示器1交替顯示左右眼影像並通過圖案相位差膜17切換入射到偏光眼鏡的偏振特性。因此，所述眼鏡型立體影像顯示器可藉由空間地劃分左右眼影像來實現立體影像。This type of stereoscopic image display 1 alternately displays left and right eye images and switches the polarization characteristics incident on the polarized glasses through the pattern retardation film 17. Therefore, the glasses-type stereoscopic image display can realize stereoscopic images by spatially dividing left and right eye images.

所述偏光眼鏡型立體影像顯示器可能會在顯示立體影像時遭受到由觀 看位置決定的3D串擾。當左眼影像與右眼影像通過單只眼睛(左眼或右眼)看到彼此互相重疊時3D串擾就出現了。當從正面光看顯示面板時，左眼影像只通過相應的第一相位差膜圖案傳送並被看到，右眼影像只通過相應的第二相位差膜圖案傳送並被看到，藉此不會察覺到3D串擾。然而，當從垂直方向觀看顯示面板時，左眼影像可通過第一相位差膜圖案以及與右眼影像對應的第二相位差膜圖案傳送從而看到左眼影像與右眼影像混合，右眼影像可通過第二相位差膜圖案以及與左眼影像對應的第一相位差膜圖案傳送從而看到右眼影像與左眼影像混合，藉此就會察覺到3D串擾。The polarized glasses type stereoscopic image display may suffer from the view when displaying a stereoscopic image Look at the 3D crosstalk determined by the location. 3D crosstalk occurs when the left eye image and the right eye image are seen to overlap each other by a single eye (left eye or right eye). When the display panel is viewed from the front light, the left-eye image is transmitted and seen only through the corresponding first retardation film pattern, and the right-eye image is transmitted and seen only through the corresponding second retardation film pattern, thereby not Will be aware of 3D crosstalk. However, when viewing the display panel from the vertical direction, the left-eye image can be transmitted through the first retardation film pattern and the second retardation film pattern corresponding to the right-eye image to see that the left-eye image and the right-eye image are mixed, the right eye. The image can be transmitted through the second retardation film pattern and the first retardation film pattern corresponding to the left eye image to see that the right eye image and the left eye image are mixed, whereby 3D crosstalk is perceived.

通常，立體影像顯示器上的垂直視角係定義為察覺到3D串擾的可能性在10%以下的上下視角的和。所述垂直視角與黑色矩陣的寬度、所述濾色片與所述圖案相位差膜之間的距離等等密切相關。藉由增加所述黑色矩陣的寬度，3D串擾可以得到改善，垂直視角也就可以變寬，但是孔徑比和亮度則可能會降低。Typically, the vertical viewing angle on a stereoscopic image display is defined as the sum of the top and bottom viewing angles where the probability of 3D crosstalk is less than 10%. The vertical viewing angle is closely related to the width of the black matrix, the distance between the color filter and the retardation film of the pattern, and the like. By increasing the width of the black matrix, 3D crosstalk can be improved, and the vertical viewing angle can be widened, but the aperture ratio and brightness may be reduced.

先前技術的偏光眼鏡型立體影像顯示器已經通過增加黑色矩陣的寬度而獲得了所需的垂直視角，但卻忽視了降低了孔徑比與亮度。The prior art polarized glasses type stereoscopic image display has obtained the desired vertical viewing angle by increasing the width of the black matrix, but neglects to reduce the aperture ratio and brightness.

本發明一方面是為了提供一種能夠最小限度地降低孔徑比與亮度且展寬垂直視角的偏光眼鏡型立體影像顯示器。One aspect of the present invention is to provide a polarized glasses type stereoscopic image display capable of minimizing aperture ratio and brightness and widening a vertical viewing angle.

在下文中，下面將參考第2圖至第28圖詳細描述本發明的示範性實施例。Hereinafter, an exemplary embodiment of the present invention will be described in detail below with reference to FIGS. 2 through 28.

第2圖為示意性地顯示依據本發明知偏光眼鏡型立體影像顯示器的視圖。Fig. 2 is a view schematically showing a polarized glasses type stereoscopic image display according to the present invention.

參考第2圖，依據本發明的偏光眼鏡型立體影像顯示器100包括顯示面板DP、圖案相位差膜180以及偏光眼鏡195。Referring to FIG. 2, a polarized glasses type stereoscopic image display 100 according to the present invention includes a display panel DP, a pattern retardation film 180, and polarizing glasses 195.

顯示面板DP可以為液晶顯示器(Liquid Crystal Display，LCD)，但不限於此。該顯示面板DP可以為場發射顯示器(Field Emission Display，FED)、電漿顯示面板(Plasma Display Panel，PDP)、有機發光二極體(Organic Light Emitting Diode，OLED)、電致發光裝置(Electroluminescence Device，EL)等。The display panel DP may be a liquid crystal display (LCD), but is not limited thereto. The display panel DP can be a Field Emission Display (FED), a Plasma Display Panel (PDP), an Organic Light Emitting Diode (OLED), or an Electroluminescence Device (Electroluminescence Device). , EL) and so on.

當以液晶顯示面板作為顯示面板DP實施時，立體影像顯示器100可以進一步包括位於顯示面板DP與圖案相位差膜180之間的第一偏光板170、配置在顯示面板DP下的背光單元(圖未示)、以及配置在顯示面板DP與背光單元之間的第二偏光板(圖未示)。圖案相位差膜180與偏光眼鏡195為立體影像顯示元件，其藉由空間地劃分左右眼影像來實現雙眼視差。When the liquid crystal display panel is implemented as the display panel DP, the stereoscopic image display 100 may further include a first polarizing plate 170 between the display panel DP and the pattern retardation film 180, and a backlight unit disposed under the display panel DP (not shown) And a second polarizing plate (not shown) disposed between the display panel DP and the backlight unit. The pattern retardation film 180 and the polarized glasses 195 are stereoscopic image display elements that realize binocular parallax by spatially dividing left and right eye images.

顯示面板DP具有兩塊玻璃基板以及形成在它們之間的液晶層。一濾色片陣列形成在第一玻璃基板上，一薄膜電晶體陣列形成在第二玻璃基板上。濾色片陣列包括黑色矩陣、濾色器等。第一偏光板170貼附在第一玻璃基板上。左眼影像L與右眼影像R以逐行的方式交替顯示在顯示面板DP上。偏光板170只傳送來源於穿過顯示面板DP的液晶層的入射光的特定線性偏振光。The display panel DP has two glass substrates and a liquid crystal layer formed therebetween. A color filter array is formed on the first glass substrate, and a thin film transistor array is formed on the second glass substrate. The color filter array includes a black matrix, a color filter, and the like. The first polarizing plate 170 is attached to the first glass substrate. The left-eye image L and the right-eye image R are alternately displayed on the display panel DP in a row-by-row manner. The polarizing plate 170 transmits only specific linearly polarized light originating from incident light passing through the liquid crystal layer of the display panel DP.

圖案相位差膜180貼附於顯示面板DP的第一偏光板170上。第一相位差膜圖案形成在圖案相位差膜180的奇數行，第二相位差膜圖案形成在圖案相位差膜180的偶數行。第一相位差膜圖案設置以面對用於在顯示面板DP上顯示左眼影像L的行。第二相位差膜圖案設置以面對用於在顯示面板DP上顯示右眼影像R的行。第一相位差膜圖案的光吸收軸與第二相位差膜圖案的光吸收軸彼此不同。第一相位差膜圖案將通過入射至第一偏光板170 的左眼影像L的線性偏振光的相位延遲了1/4個波長使得該入射光作為第一偏振光通過(例如，左圓偏振光)。第二相位差膜圖案將通過入射至第一偏光板170的右眼影像R的線性偏振光的相位延遲了3/4個波長使得該入射光作為第二偏振光通過(例如，右圓偏振光)。第一相位差膜圖案可通過用以傳送左圓偏振分量並阻擋右圓偏振分量的偏振濾光片來實現，第二相位差膜圖案可通過藉由用於傳送右圓偏振分量並阻擋左圓偏振分量的偏振濾光片來實現。The pattern retardation film 180 is attached to the first polarizing plate 170 of the display panel DP. The first retardation film pattern is formed in odd rows of the pattern retardation film 180, and the second retardation film pattern is formed in even rows of the pattern retardation film 180. The first retardation film pattern is disposed to face a row for displaying the left-eye image L on the display panel DP. The second retardation film pattern is disposed to face a row for displaying the right-eye image R on the display panel DP. The light absorption axis of the first retardation film pattern and the light absorption axis of the second retardation film pattern are different from each other. The first retardation film pattern will pass through to the first polarizing plate 170 The phase of the linearly polarized light of the left-eye image L is delayed by 1/4 wavelength such that the incident light passes as the first polarized light (for example, left circularly polarized light). The second retardation film pattern delays the phase of the linearly polarized light incident to the right-eye image R of the first polarizing plate 170 by 3/4 wavelengths so that the incident light passes as the second polarized light (for example, right circularly polarized light) ). The first retardation film pattern can be realized by a polarizing filter for transmitting a left circularly polarized component and blocking a right circularly polarized component, and the second retardation film pattern can be used by transmitting a right circularly polarized component and blocking the left circle Polarization filter with polarization component is implemented.

只允許第一偏振分量由此通過的偏光膜緊密結合於偏光眼鏡195的左眼上，而只允許第二偏振分量由此通過的偏光膜緊密結合於偏光眼鏡195的右眼上。因此，配戴偏光眼鏡195的觀看者左眼只看到了左眼影像L，右眼只看到了右眼影像R，從而感受到的顯示在顯示面板DP的影像是立體影像。The polarizing film that allows only the first polarization component to pass therethrough is tightly bonded to the left eye of the polarizing glasses 195, and only the polarizing film through which the second polarizing component passes is tightly bonded to the right eye of the polarizing glasses 195. Therefore, the viewer wearing the polarizing glasses 195 sees only the left-eye image L in the left eye, and only the right-eye image R in the right eye, so that the image displayed on the display panel DP is a stereoscopic image.

在依據本發明的偏光眼鏡型立體影像顯示器100中，為了使孔徑比與亮度的減少最小化並展寬垂直視角，而將從顯示器100上側向顯示器100下側的方向上排列成行的黑色條紋圖案165形成在顯示面板DP與圖案相位差膜180之間與黑色矩陣圖案130相對應的特定位置上，如第3圖、第4圖所示。當黑色條紋圖案165如上述形成時，為了均勻地使取決於視角的亮度的降低最小化，依據本發明的偏光眼鏡型立體影像顯示器100可設計為黑色條紋圖案165的寬度在顯示面板DP的中部相對較大，而在顯示面板DP的上部與下部相對較小，如第9圖、第11圖、第24圖及第25圖所示。當黑色條紋圖案165如上所述地形成時，為了獲得足夠的垂直視角，依據本發明的偏光眼鏡型立體影像顯示器100可設計為黑色條紋圖案165的寬度在顯示面板DP的中部相對較小，而在顯示面板DP的上部與下部相對較大。當黑色條紋圖案165如上述形成時，為了展寬垂直視角以及均勻地使取決於所述視角的亮度的降低最小化，依據本發明的偏光眼鏡型立體影像顯示器100可設計為黑色條紋圖案165在與亮度均勻度測量範圍相對應的顯示面板DP的中心區塊寬度為一致的，而在顯示面板的上下區塊寬度為逐漸變化的。在本發明中，所述的上部、上區塊、中部、中心區塊、下部及下區塊係沿著從顯示器100上側向顯示器100下側的方向定義的。In the polarized glasses type stereoscopic image display 100 according to the present invention, in order to minimize the reduction in aperture ratio and luminance and widen the vertical viewing angle, black stripe patterns 165 arranged in a row from the upper side of the display 100 toward the lower side of the display 100 are arranged. It is formed at a specific position corresponding to the black matrix pattern 130 between the display panel DP and the pattern retardation film 180, as shown in FIGS. 3 and 4. When the black stripe pattern 165 is formed as described above, in order to minimize the reduction in brightness depending on the viewing angle uniformly, the polarized glasses type stereoscopic image display 100 according to the present invention may be designed such that the width of the black stripe pattern 165 is in the middle of the display panel DP It is relatively large, and is relatively small in the upper and lower portions of the display panel DP, as shown in FIG. 9, FIG. 11, FIG. 24, and FIG. When the black stripe pattern 165 is formed as described above, in order to obtain a sufficient vertical viewing angle, the polarized glasses type stereoscopic image display 100 according to the present invention may be designed such that the width of the black stripe pattern 165 is relatively small in the middle of the display panel DP, and The upper portion and the lower portion of the display panel DP are relatively large. When the black stripe pattern 165 is formed as described above, in order to broaden the vertical viewing angle and uniformly minimize the decrease in brightness depending on the viewing angle, the polarized glasses type stereoscopic image display 100 according to the present invention may be designed as a black stripe pattern 165 The central block width of the display panel DP corresponding to the brightness uniformity measurement range is uniform, and the upper and lower block widths of the display panel are gradually changed. In the present invention, the upper, upper, middle, central, lower, and lower blocks are defined along the direction from the upper side of the display 100 to the lower side of the display 100.

這將在下面詳細描述。在下文中，與第2圖相同的組成部分將配以同第2圖的元件符號一樣的元件符號作表示，它們的說明將被簡化。This will be described in detail below. In the following, the same components as those of Fig. 2 will be denoted by the same component symbols as those of Fig. 2, and their description will be simplified.

第3圖、第4圖為顯示依據本發明示範性實施例之具有黑色矩陣及彼此對應形成的黑色條紋的立體影像顯示器的視圖。第5圖舉例說明依據本發明通過最小限度地減少孔徑比與亮度來展寬垂直視角並與先前技術做比較。第6圖為顯示依據本發明之被展寬的垂直視角的實例視圖。3 and 4 are views showing a stereoscopic image display having a black matrix and black stripes formed corresponding to each other according to an exemplary embodiment of the present invention. Figure 5 illustrates the broadening of the vertical viewing angle by minimizing the aperture ratio and brightness in accordance with the present invention and comparing with prior art techniques. Figure 6 is a diagram showing an example of a widened vertical viewing angle in accordance with the present invention.

參考第3圖與第4圖，立體影像顯示器100包括顯示面板DP以及貼附在顯示面板DP上的圖案相位差薄膜185，顯示面板DP具有形成在與黑色矩陣圖案130相對應的特定位置上的黑色條紋圖案165。Referring to FIGS. 3 and 4, the stereoscopic image display 100 includes a display panel DP and a pattern phase difference film 185 attached to the display panel DP, the display panel DP having a specific position formed corresponding to the black matrix pattern 130. Black stripe pattern 165.

顯示面板DP包括薄膜電晶體陣列基板110、面對薄膜電晶體陣列基板110的濾色片陣列基板120、以及形成在該等基板110與120之間的液晶層150。薄膜電晶體陣列基板110包括複數條施加有R、G、B資料電壓的資料線、複數條與資料線相交且相繼提供有閘極脈衝的閘極線、複數個形成在資料線與閘極線的交叉點的薄膜電晶體、複數個用於在液晶單元中充電資料電壓的像素電極、以及連接到像素電極以維持液晶單元電壓的儲存電容器。The display panel DP includes a thin film transistor array substrate 110, a color filter array substrate 120 facing the thin film transistor array substrate 110, and a liquid crystal layer 150 formed between the substrates 110 and 120. The thin film transistor array substrate 110 includes a plurality of data lines to which R, G, and B data voltages are applied, a plurality of gate lines intersecting the data lines and sequentially providing gate pulses, and a plurality of gate lines formed on the data lines and the gate lines. A thin film transistor at the intersection, a plurality of pixel electrodes for charging the data voltage in the liquid crystal cell, and a storage capacitor connected to the pixel electrode to maintain the voltage of the liquid crystal cell.

面對像素電極以形成一個電場的共同電極在例如扭曲向列(Twisted Nematic，TN)模式及垂直配向(Vertical Alignment，VA)模式的垂直電場驅動類型下配置在濾色片陣列基板120上，且連同像素電極在例如平面轉換(In Plane Switching，IPS)模式及邊界電場轉換(Fringe Field Switching，FFS)模式的水平電場類型下配置在薄膜電晶體陣列基板110上。A common electrode facing the pixel electrode to form an electric field is disposed on the color filter array substrate 120 in a vertical electric field driving type such as a twisted nematic (TN) mode and a vertical alignment (VA) mode, and The thin film transistor array substrate 110 is disposed along with the pixel electrode in a horizontal electric field type such as an In Plane Switching (IPS) mode and a Fringe Field Switching (FFS) mode.

R、G、B濾色片135、黑色矩陣圖案130以及保護層140形成在濾色片陣列基板120上。濾色片135將從背光單元發射的光與經過液晶層150傳送的光轉變成紅、綠、藍。黑色矩陣圖案130遮蔽了鄰近的濾色片135之間的光從而防止濾色片135之間的光干涉(optical interference)。保護層140保護濾色片135與黑色矩陣圖案130。The R, G, and B color filters 135, the black matrix pattern 130, and the protective layer 140 are formed on the color filter array substrate 120. The color filter 135 converts light emitted from the backlight unit and light transmitted through the liquid crystal layer 150 into red, green, and blue. The black matrix pattern 130 shields light between adjacent color filters 135 to prevent optical interference between the color filters 135. The protective layer 140 protects the color filter 135 and the black matrix pattern 130.

在薄膜電晶體陣列基板110與濾色片陣列基板120中，用來設置液晶預傾角(pre-tilt angle)的配向層(alignment layer)分別形成在與液晶層150接觸的內表面，以及形成用來留有液晶單元的單元間隙的柱狀間隔145。In the thin film transistor array substrate 110 and the color filter array substrate 120, an alignment layer for setting a liquid crystal pre-tilt angle is formed on the inner surface in contact with the liquid crystal layer 150, respectively, and is formed. A columnar space 145 in which the cell gap of the liquid crystal cell is left is left.

第一偏光板170貼附在濾色片陣列基板120的背面。黑色條紋圖案165形成在與濾色片陣列基板120的背面與第一偏光板170之間的黑色矩陣圖案130相對應的特定位置上。由透明金屬製成的背面金屬層160(下文中被稱作“背面ITO”)可進一步形成在濾色片陣列基板120的背面與第一偏光板 170之間用來釋放靜電。在這種情況下，如第3圖所示，黑色條紋圖案165可形成在濾色片陣列基板120的背面與背面ITO 160之間。像黑色矩陣圖案130一樣，黑色條紋圖案165由不透明/非透射材料形成。當黑色條紋圖案165由不透明樹脂形成時，黑色條紋圖案165的硬度低於背面ITO 160的硬度。因此，背面ITO 160除了有釋放靜電的作用，此外還能作用為保護膜來保護黑色條紋圖案165。也就是，背面ITO 160形成以覆蓋黑色條紋圖案165，如第3圖所示，從而防止在隨後的清洗等製程步驟中黑色條紋圖案165的丟失。The first polarizing plate 170 is attached to the back surface of the color filter array substrate 120. The black stripe pattern 165 is formed at a specific position corresponding to the black matrix pattern 130 between the back surface of the color filter array substrate 120 and the first polarizing plate 170. A back metal layer 160 (hereinafter referred to as "back ITO") made of a transparent metal may be further formed on the back surface of the color filter array substrate 120 and the first polarizing plate. Used between 170 to discharge static electricity. In this case, as shown in FIG. 3, a black stripe pattern 165 may be formed between the back surface of the color filter array substrate 120 and the back surface ITO 160. Like the black matrix pattern 130, the black stripe pattern 165 is formed of an opaque/non-transmissive material. When the black stripe pattern 165 is formed of an opaque resin, the hardness of the black stripe pattern 165 is lower than that of the back surface ITO 160. Therefore, the back surface ITO 160 functions as a protective film to protect the black stripe pattern 165 in addition to the action of releasing static electricity. That is, the back surface ITO 160 is formed to cover the black stripe pattern 165 as shown in FIG. 3, thereby preventing the loss of the black stripe pattern 165 in the subsequent cleaning and the like process steps.

另一方面，如第4圖所示，黑色條紋圖案165可直接與第一偏光板170接觸，而沒有背面ITO 160對其進行保護，這樣配置在濾色片陣列基板120的背面上。在這種情況下，黑色條紋圖案165可由不透明金屬形成從而達到足夠的硬度以防止在隨後的清洗等製程步驟中丟失以及能夠釋放由第一偏光板170的依附而產生的靜電。On the other hand, as shown in FIG. 4, the black stripe pattern 165 can be directly in contact with the first polarizing plate 170 without the back surface ITO 160 protecting it so as to be disposed on the back surface of the color filter array substrate 120. In this case, the black stripe pattern 165 may be formed of an opaque metal to achieve sufficient hardness to prevent loss in a process step such as subsequent cleaning and to release static electricity generated by the attachment of the first polarizing plate 170.

如果背面ITO 160由不透明金屬形成，那麼如第3圖所示，黑色條紋圖案165可形成在背面ITO 160與第一偏光板170之間。If the back surface ITO 160 is formed of an opaque metal, as shown in FIG. 3, a black stripe pattern 165 may be formed between the back surface ITO 160 and the first polarizing plate 170.

為了使亮度的減少最小化，第3圖與第4圖中的黑色條紋圖案165可與在對應於黑色矩陣圖案130的區域內的黑色矩陣圖案130重疊。In order to minimize the decrease in luminance, the black stripe pattern 165 in FIGS. 3 and 4 may overlap with the black matrix pattern 130 in the region corresponding to the black matrix pattern 130.

圖案相位差薄膜185包括貼附在第一偏光板170上的圖案相位差膜180以及用來保護圖案相位差膜180的保護膜182。圖案相位差膜180包括逐行圖案化的第一相位差膜圖案180a以及第二相位差膜圖案180b，其作用如上面所述。The pattern retardation film 185 includes a pattern retardation film 180 attached to the first polarizing plate 170 and a protective film 182 for protecting the pattern retardation film 180. The pattern retardation film 180 includes a first retardation film pattern 180a and a second retardation film pattern 180b which are patterned row by row, and functions as described above.

由於第5圖(a)所示的先前技術的立體影像顯示器沒有特殊的黑色條紋圖案，所以必須要使黑色矩陣圖案130的寬度夠大才能獲得所需的垂直視角(θ)。Since the prior art stereoscopic image display shown in Fig. 5(a) does not have a special black stripe pattern, it is necessary to make the width of the black matrix pattern 130 large enough to obtain a desired vertical viewing angle (?).

反之，第5圖(b)所示的依據本發明示範性實施例之立體影像顯示器提供的黑色矩陣圖案130的寬度小於先前技術黑色矩陣圖案130的寬度，並藉由在黑色矩陣圖案130的相應位置形成黑色條紋圖案165來獲得與先前技術相同的垂直視角(θ)。假設垂直視角被定義為察覺到3D串擾的可能性在10%以下的上下視角的和，那麼本發明能夠使孔徑比與亮度的減少最小化，並且能夠使垂直視角展寬到大約27.5度，如第6圖所示。On the other hand, the width of the black matrix pattern 130 provided by the stereoscopic image display according to the exemplary embodiment of the present invention shown in FIG. 5(b) is smaller than the width of the prior art black matrix pattern 130, and by the corresponding in the black matrix pattern 130. The position forms a black stripe pattern 165 to obtain the same vertical viewing angle (θ) as the prior art. Assuming that the vertical viewing angle is defined as the sum of the upper and lower viewing angles where the probability of 3D crosstalk is perceived to be less than 10%, the present invention can minimize the reduction in aperture ratio and brightness, and can widen the vertical viewing angle to approximately 27.5 degrees, as in Figure 6 shows.

如上所述，先前技術的立體影像顯示器為了展寬垂直視角而增加了黑色矩陣圖案的寬度；然而本發明的示範性實施例所具有的優點是：藉由在濾色片陣列基板的第一平面形成比先前技術狹窄的黑色矩陣圖案以及在與第一平面相對的濾色片陣列基板的第二平面上形成與黑色矩陣圖案重疊的黑色條紋這樣的方式來實現與先前技術相同的垂直視角並阻止孔徑比與亮度的減少。As described above, the prior art stereoscopic image display increases the width of the black matrix pattern in order to widen the vertical viewing angle; however, an exemplary embodiment of the present invention has an advantage of being formed in the first plane of the color filter array substrate. Realizing the same vertical viewing angle as the prior art and preventing the aperture by forming a black matrix pattern narrower than the prior art and forming a black stripe overlapping the black matrix pattern on the second plane of the color filter array substrate opposite to the first plane Ratio and brightness reduction.

儘管如此，依據本發明的示範性實施例，部分的亮度減少可取決於視角而出現。Nonetheless, in accordance with an exemplary embodiment of the present invention, a portion of the brightness reduction may occur depending on the viewing angle.

第7圖與第8圖為顯示取決於視角之亮度的部分減少的實例視圖。在第7圖與第8圖中，(a’)、(b’)與(c’)為觀看者的理想觀看範圍，(a)、(b)與(c)為實際有效觀看範圍。Figures 7 and 8 are example views showing partial reduction depending on the brightness of the viewing angle. In Figs. 7 and 8, (a'), (b') and (c') are ideal viewing ranges for the viewer, and (a), (b) and (c) are actual effective viewing ranges.

第7圖為觀看者使他或她的眼睛平行於立體影像顯示器的中部來觀看立體影像顯示器的情況的實例。Figure 7 is an example of a situation in which a viewer views his or her eyes parallel to the middle of the stereoscopic image display to view the stereoscopic image display.

當觀看者觀看位於立體影像顯示器中部的影像時，觀看者的觀看範圍沒有被黑色條紋圖案165遮掩，如第7圖所示。因此，觀看者可以在沒有亮度減少的情況下觀看中部的影像。在這種情況下，觀看者的理想觀看範圍(b’)與實際有效觀看範圍(b)完全相同。When the viewer views the image located in the middle of the stereoscopic image display, the viewing range of the viewer is not obscured by the black stripe pattern 165, as shown in FIG. Therefore, the viewer can view the image of the middle without a decrease in brightness. In this case, the viewer's ideal viewing range (b') is exactly the same as the actual effective viewing range (b).

另一方面，當觀看者觀看位於立體影像顯示器上部的影像時，觀看者的觀看範圍被黑色條紋圖案165遮掩，如第7圖所示。在這種情況下，實際有效觀看範圍(a)與觀看者的理想觀看範圍(a’)相比變窄。結果，觀看者在低亮度下觀看位於上部的影像。同樣地，當觀看者觀看位於立體影像顯示器下部的影像時，觀看者的觀看範圍被黑色條紋圖案165遮掩，實際有效觀看範圍(c)與觀看者的理想觀看範圍(c’)相比變窄。結果，觀看者在低亮度下觀看位於下部的影像。On the other hand, when the viewer views the image located on the upper portion of the stereoscopic image display, the viewing range of the viewer is obscured by the black stripe pattern 165 as shown in FIG. In this case, the actual effective viewing range (a) is narrower than the viewer's ideal viewing range (a'). As a result, the viewer views the image located at the upper portion at low brightness. Similarly, when the viewer views the image located at the lower portion of the stereoscopic image display, the viewing range of the viewer is obscured by the black stripe pattern 165, and the actual effective viewing range (c) is narrower than the ideal viewing range (c') of the viewer. . As a result, the viewer views the image located at the lower portion at a low brightness.

第8圖為觀看者使他或她的眼睛平行於立體影像顯示器的下部來觀看立體影像顯示器的情況的舉例。Figure 8 is an illustration of a situation in which a viewer views his or her eyes parallel to the lower portion of the stereoscopic image display to view the stereoscopic image display.

當觀看者觀看位於立體影像顯示器下部的影像時，觀看者的觀看範圍沒有被黑色條紋圖案165遮掩，如第8圖所示。在這種情況下，觀看者的理想觀看範圍(c’)與實際有效觀看範圍(c)完全相同，從而觀看者可以在沒有亮度減少的情況下觀看下部的影像。When the viewer views the image located at the lower portion of the stereoscopic image display, the viewing range of the viewer is not obscured by the black stripe pattern 165, as shown in FIG. In this case, the viewer's ideal viewing range (c') is exactly the same as the actual effective viewing range (c), so that the viewer can view the lower image without the brightness reduction.

另一方面，當該觀看者觀看位於該立體影像顯示器中部的影像時，該觀看者的觀看範圍被黑色條紋圖案165遮掩。結果，實際有效觀看範圍(b)與該觀看者的理想觀看範圍(b’)相比變窄，因此造成亮度降低。而且，當該觀看者觀看位於該立體影像顯示器上部的影像時，該觀看者的觀看範圍被黑色條紋圖案165遮掩的範圍變寬。所以，實際有效觀看範圍(a)與該觀看者的理想觀看範圍(a’)相比變得更窄，這導致更明顯的亮度降低。On the other hand, when the viewer views an image located in the middle of the stereoscopic image display, the viewing range of the viewer is obscured by the black stripe pattern 165. As a result, the actual effective viewing range (b) is narrower than the viewer's ideal viewing range (b'), thus causing a decrease in brightness. Moreover, when the viewer views an image located on the upper portion of the stereoscopic image display, the range in which the viewer's viewing range is obscured by the black stripe pattern 165 is widened. Therefore, the actual effective viewing range (a) becomes narrower than the viewer's ideal viewing range (a'), which results in a more pronounced brightness reduction.

所以，即使黑色條紋圖案165在與黑色矩陣圖案130對應的區域內形成有比黑色矩陣圖案130小的面積，但是由於觀看立體影像顯示器的不同位置之間的視角差異還是會如第7圖所示導致在上部與下部而非中部的影像亮度降低，以及如第8圖所示導致在中部與上部而非下部的影像亮度降低。Therefore, even if the black stripe pattern 165 is formed with a smaller area than the black matrix pattern 130 in the area corresponding to the black matrix pattern 130, the difference in viewing angle between the different positions of the viewing stereoscopic image display will be as shown in FIG. This results in a reduction in the brightness of the image in the upper and lower portions rather than in the middle, and a decrease in the brightness of the image in the middle and upper portions rather than the lower portion as shown in Fig. 8.

第9圖為顯示依據本發明示範性實施例之被提供用來改善亮度均勻度的偏光眼鏡型立體影像顯示器的視圖。第10圖為顯示從立體影像顯示器的中部向其上部與下部逐漸變小的黑色條紋圖案的寬度的視圖。在第10圖中，縱軸代表顯示位置，橫軸代表該黑色條紋圖案的寬度。Fig. 9 is a view showing a polarized glasses type stereoscopic image display provided to improve brightness uniformity according to an exemplary embodiment of the present invention. Fig. 10 is a view showing the width of a black stripe pattern which gradually becomes smaller from the middle portion of the stereoscopic image display to the upper and lower portions thereof. In Fig. 10, the vertical axis represents the display position, and the horizontal axis represents the width of the black stripe pattern.

第9圖的配置基本上與第3圖、第4圖中所示的相同，除了黑色條紋圖案165的寬度是取決於該顯示面板上的顯示位置而變化之外。The configuration of Fig. 9 is basically the same as that shown in Figs. 3 and 4 except that the width of the black stripe pattern 165 varies depending on the display position on the display panel.

參考第9圖，在依據示範性實施例的偏光眼鏡型立體影像顯示器中，為了解決取決於每個位置的視角的亮度均勻度減少的問題，黑色條紋圖案165具有由顯示位置決定的不同寬度。在第9圖的示範性實施例中，黑色條紋圖案165的寬度在顯示面板的中部最大，然後從顯示面板的中部向其上部與下部變小。Referring to Fig. 9, in the polarized glasses type stereoscopic image display according to the exemplary embodiment, in order to solve the problem of reduction in luminance uniformity depending on the angle of view of each position, the black stripe pattern 165 has a different width determined by the display position. In the exemplary embodiment of FIG. 9, the width of the black stripe pattern 165 is largest in the middle of the display panel, and then becomes smaller from the middle of the display panel toward the upper and lower portions thereof.

如第10圖所示，假定位於顯示面板中部的黑色條紋圖案165的寬度為“X”，那麼黑色條紋圖案165的寬度可以向顯示面板的上部與下部逐漸減少，到上部與下部的最外側時變為“X/7~X/4”。例如，如果位於顯示面板中部的黑色條紋圖案165的寬度為50μm，那麼位於顯示面板上部與下部最外側的黑色條紋圖案165的寬度可在7.1μm至12.5μm範圍內變化。As shown in FIG. 10, assuming that the width of the black stripe pattern 165 located at the center of the display panel is "X", the width of the black stripe pattern 165 may gradually decrease toward the upper and lower portions of the display panel to the outermost sides of the upper and lower portions. It becomes "X/7~X/4". For example, if the width of the black stripe pattern 165 located at the center of the display panel is 50 μm, the width of the black stripe pattern 165 located at the outermost and lower outermost sides of the display panel may vary from 7.1 μm to 12.5 μm.

藉由取決於顯示位置來變化黑色條紋圖案165的寬度，即便觀看者在如第7圖所示的位置觀看立體影像顯示器的上部與下部，觀看者的觀看範圍被黑色條紋圖案165遮掩的範圍也變窄，從而使在上部與下部亮度最小 化地降低。結果，由每個位置上的視角決定的亮度均勻度減少的問題能夠得以解決。By varying the width of the black stripe pattern 165 depending on the display position, even if the viewer views the upper and lower portions of the stereoscopic image display at the position as shown in FIG. 7, the range in which the viewer's viewing range is hidden by the black stripe pattern 165 is also Narrowed to minimize brightness at the top and bottom Reduced. As a result, the problem of reduced brightness uniformity determined by the angle of view at each position can be solved.

作為一個典型的觀看者在如第7圖、第9圖及第10圖所示的位置(就座的狀態)觀看顯示器影像，是僅僅舉例說明對於這個位置的亮度均勻度的解決方案。但是，本發明並不限於此。儘管沒有明確地顯示，但在本發明中，黑色條紋圖案165的寬度可以在顯示面板的下部為最大，然後從顯示面板的下部向其上部逐漸表小。這種情況是觀看者使他或她的眼睛平行於立體影像顯示器的下部(平躺的狀態)觀看顯示器影像，如第8圖所示。Viewing the display image as a typical viewer at the position (sitting state) as shown in Figs. 7, 9, and 10 is merely a solution to the brightness uniformity at this position. However, the invention is not limited thereto. Although not explicitly shown, in the present invention, the width of the black stripe pattern 165 may be maximized at the lower portion of the display panel, and then gradually narrowed from the lower portion of the display panel toward the upper portion thereof. In this case, the viewer views his or her eyes parallel to the lower portion of the stereoscopic image display (in a flat state), as shown in FIG.

第11圖為顯示依據本發明示範性實施例之被提供用來改善亮度均勻度的偏光眼鏡型立體影像顯示器的視圖。第12圖為顯示從立體影像顯示器的中部向其上部與下部階梯式地變小的黑色條紋圖案165的寬度的視圖。Fig. 11 is a view showing a polarized glasses type stereoscopic image display provided to improve brightness uniformity according to an exemplary embodiment of the present invention. Fig. 12 is a view showing the width of the black stripe pattern 165 which becomes stepwise from the middle of the stereoscopic image display to the upper and lower portions thereof.

第11圖的配置基本上與第9圖中所示的相同，除了每個顯示區塊的黑色條紋圖案165的寬度是變化的。The configuration of Fig. 11 is basically the same as that shown in Fig. 9, except that the width of the black stripe pattern 165 of each display block is varied.

參考第11圖，在依據本發明示範性實施例的偏光眼鏡型立體影像顯示器中，顯示面板沿著顯示面板的垂直方向分成複數個區塊，而每個顯示區塊的黑色條紋圖案165具有不同的寬度，這是為了展寬垂直視角並改善由每個位置的視角決定的亮度均勻度減少的問題。黑色條紋圖案165的寬度在顯示面板的中心區塊最大，然後從顯示面板的中心區塊向其最上方與最下方的區塊逐漸變小。然而，在垂直方向上相鄰的複數個黑色條紋圖案165可被包含在一個區塊內，並且在同一區塊內的黑色條紋圖案165具有相同的寬度。Referring to FIG. 11, in a polarized glasses type stereoscopic image display according to an exemplary embodiment of the present invention, a display panel is divided into a plurality of blocks along a vertical direction of the display panel, and a black stripe pattern 165 of each display block has a different The width, which is to broaden the vertical viewing angle and improve the reduction in brightness uniformity determined by the angle of view of each position. The width of the black stripe pattern 165 is the largest in the central block of the display panel, and then gradually decreases from the central block of the display panel to the uppermost and lowermost blocks thereof. However, the plurality of black stripe patterns 165 adjacent in the vertical direction may be contained in one block, and the black stripe patterns 165 in the same block have the same width.

如第12圖所示，假定位於顯示面板中心區塊的黑色條紋圖案165的寬度為“X”，則黑色條紋圖案165的寬度可向顯示面板的上部與下部呈階梯式地逐漸減少，到最上方區塊及最下方區塊時變為“X/7~X/4”。As shown in FIG. 12, assuming that the width of the black stripe pattern 165 located in the central block of the display panel is "X", the width of the black stripe pattern 165 can be gradually reduced stepwise to the upper and lower portions of the display panel. The upper block and the lowermost block become "X/7~X/4".

第13圖顯示了依據本發明第9圖至第12圖的亮度測量結果。對本發明的測量，當黑色條紋圖案配置於中部時黑色條紋圖案的寬度為50μm，然後向上部與下部逐漸地或階梯式地變小，到最上側與最下側時變為10μm。Fig. 13 shows the results of luminance measurement according to Figs. 9 to 12 of the present invention. For the measurement of the present invention, the black stripe pattern has a width of 50 μm when the black stripe pattern is disposed in the middle portion, and then becomes gradually smaller or stepwise to the upper portion and the lower portion, and becomes 10 μm to the uppermost side and the lowermost side.

參考第13圖，如果黑色條紋圖案的寬度以固定比例從顯示面板的中部向其上部與下部減少，如第9圖至第12圖所示，那麼與寬度固定為50μm的黑色條紋圖案相比(參見第3圖、第4圖)而不管顯示位置，則在顯示面板的上部與下部獲得了高亮度。在第13圖中，“A”代表第9圖至第12圖 中顯示面板的上部與下部的亮度。“B”表示第3圖、第4圖中顯示面板的上部與下部的亮度。如第13圖中所說明的，“A”顯然高於“B”。Referring to Fig. 13, if the width of the black stripe pattern is reduced from the central portion of the display panel to the upper portion and the lower portion thereof at a fixed ratio, as shown in Figs. 9 to 12, it is compared with a black stripe pattern having a width fixed at 50 μm ( Referring to Fig. 3 and Fig. 4) regardless of the display position, high brightness is obtained at the upper and lower portions of the display panel. In Fig. 13, "A" stands for Fig. 9 to Fig. 12 The brightness of the upper and lower parts of the panel is displayed. "B" indicates the brightness of the upper and lower portions of the display panel in Figs. 3 and 4. As illustrated in Figure 13, "A" is clearly higher than "B".

第14A圖與第14B圖為顯示根據立體影像顯示器的大小而決定的合適的觀看距離的視圖。FIGS. 14A and 14B are views showing a suitable viewing distance determined according to the size of the stereoscopic image display.

如第14A圖中所示的小型式立體影像顯示器，合適的觀看距離相對較小，即大約1 H1到1.5 H1。這裏，“H1”表示小型影像顯示器100的垂直長度(H1)。在根據位置改變黑色條紋圖案的寬度時，應考慮到垂直視角和適合的觀看距離。對於小型立體影像顯示器所需的垂直視角相對較小，即12°至15°。這類小型立體影像顯示器具有小的觀看距離以及需要一個窄的垂直視角，即便當黑色條紋圖案的寬度在上部與下部減少時也不是極易能夠察覺到3D串擾。因此，本發明第9圖、第12圖的上述配置對於改善小型立體影像顯示器的亮度均勻度是有效的。As with the compact stereoscopic image display shown in Fig. 14A, a suitable viewing distance is relatively small, i.e., approximately 1 H1 to 1.5 H1. Here, "H1" indicates the vertical length (H1) of the small image display 100. When changing the width of the black stripe pattern according to the position, a vertical viewing angle and a suitable viewing distance should be considered. The vertical viewing angle required for a small stereoscopic image display is relatively small, ie 12° to 15°. Such small stereoscopic image displays have a small viewing distance and require a narrow vertical viewing angle, even when the width of the black stripe pattern is reduced in the upper and lower portions, and 3D crosstalk is not easily perceived. Therefore, the above arrangement of the ninth and twelfthth aspects of the present invention is effective for improving the brightness uniformity of the small-sized stereoscopic image display.

如第14B圖中所示的大型式立體影像顯示器，合適的觀看距離相對較大，即大約3 H2到5 H2。這裏，“H2”表示大型影像顯示器100的垂直長度(H2)。對於大型立體影像顯示器所需的垂直視角相對較大，即20°至26°。這類大型立體影像顯示器具有大的觀看距離以及需要一個寬的垂直視角，當黑色條紋圖案的寬度在該上部與下部減少時可能容易察覺到3D串擾。因此，對於大型立體影像顯示器而言，減少在上部與下部的3D串擾是非常重要的，即使亮度均勻度被降低到某種程度。As with the large-scale stereoscopic image display shown in Fig. 14B, a suitable viewing distance is relatively large, i.e., approximately 3 H2 to 5 H2. Here, "H2" represents the vertical length (H2) of the large-sized image display device 100. The vertical viewing angle required for large stereoscopic image displays is relatively large, ie 20° to 26°. Such large stereoscopic image displays have a large viewing distance and require a wide vertical viewing angle, which may be easily perceived when the width of the black stripe pattern is reduced at the upper and lower portions. Therefore, for a large stereoscopic image display, it is very important to reduce the 3D crosstalk at the upper and lower portions, even if the brightness uniformity is lowered to some extent.

第15圖為顯示依據本發明示範性實施例之被提供用來減少3D串擾的偏光眼鏡型立體影像顯示器的視圖。第16圖為顯示從立體影像顯示器的中部向其上部與下部逐漸變大的黑色條紋圖案165寬度的視圖。Figure 15 is a view showing a polarized glasses type stereoscopic image display provided to reduce 3D crosstalk according to an exemplary embodiment of the present invention. Fig. 16 is a view showing the width of the black stripe pattern 165 which gradually becomes larger from the middle portion of the stereoscopic image display toward the upper and lower portions thereof.

參考第15圖，在依據示範性實施例的該偏光眼鏡型立體影像顯示器中，為了減少在該上部與下部的3D串擾，黑色條紋圖案165的寬度從中部向上部與下部逐漸增加。在第15圖的示範性實施例中，黑色條紋圖案165的寬度在顯示面板的中部最小，然後從顯示面板的中部向其上部與下部逐漸變大。Referring to Fig. 15, in the polarized glasses type stereoscopic image display according to an exemplary embodiment, in order to reduce 3D crosstalk at the upper and lower portions, the width of the black stripe pattern 165 gradually increases from the central portion to the upper portion and the lower portion. In the exemplary embodiment of Fig. 15, the width of the black stripe pattern 165 is the smallest in the middle of the display panel, and then gradually increases from the middle of the display panel toward the upper and lower portions thereof.

如第16圖所示，假定位於顯示面板中部的黑色條紋圖案的寬度為“Y“，那麼黑色條紋圖案165的寬度可向顯示面板的上部與下部逐漸增加，到上部與下部的最外側時變成“5Y/4~6Y/4”。如第15圖與第16圖所示之本發明的示範性實施例在減少大型立體影像顯示器的3D串擾這方面是有效的。As shown in FIG. 16, assuming that the width of the black stripe pattern in the middle of the display panel is "Y", the width of the black stripe pattern 165 may gradually increase toward the upper and lower portions of the display panel, and become the outermost portion of the upper and lower portions. "5Y/4~6Y/4". The exemplary embodiment of the present invention as shown in Figs. 15 and 16 is effective in reducing 3D crosstalk of a large stereoscopic image display.

第17圖至第21圖為顯示依據本發明示範性實施例之被提供用來改善亮度均勻度以及減少3D串擾的偏光眼鏡型立體影像顯示器的視圖。本發明接下來的示範性實施例能夠應用於小型和大型兩類立體影像顯示器中。17 to 21 are views showing a polarized glasses type stereoscopic image display provided to improve luminance uniformity and reduce 3D crosstalk according to an exemplary embodiment of the present invention. The following exemplary embodiment of the present invention can be applied to both small and large types of stereoscopic image displays.

參考第17圖，在本發明的示範性實施例中，顯示面板DP被分成三個區塊。所述三個區塊包括一個中心區塊，包括複數個用來測量亮度均勻度的亮度測量點；一個上區塊，設置在中心區塊上面；以及一個下區塊，設置在中心區塊的下面。中心區塊可擁有比上區塊與下區塊大的面積。假設顯示面板DP的垂直長度為“H”，則中心區塊的垂直長度可為7H/9，上區塊與下區塊的垂直長度可分別為1H/9。中心區塊對應一個亮度均勻度測量範圍。上區塊與該下區塊可以具有相同的面積或不同的面積。Referring to Fig. 17, in an exemplary embodiment of the present invention, the display panel DP is divided into three blocks. The three blocks include a central block including a plurality of brightness measurement points for measuring brightness uniformity; an upper block disposed above the central block; and a lower block disposed at the central block below. The central block can have a larger area than the upper block and the lower block. Assuming that the vertical length of the display panel DP is "H", the vertical length of the central block may be 7H/9, and the vertical length of the upper block and the lower block may be 1H/9, respectively. The central block corresponds to a brightness uniformity measurement range. The upper block and the lower block may have the same area or different areas.

本發明的示範性實施例具有如下優點：藉由在佔據相對較大面積的中心區塊形成寬度一致的黑色條紋圖案165以及在佔據相對較小面積的上區塊與下區塊形成寬度逐漸變化的黑色條紋圖案165來改善亮度均勻度以及抑制3D串擾。An exemplary embodiment of the present invention has an advantage of forming a gradual change in width by forming a black stripe pattern 165 having a uniform width in a central block occupying a relatively large area and forming an upper block and a lower block occupying a relatively small area. The black stripe pattern 165 improves brightness uniformity and suppresses 3D crosstalk.

在本發明的示範性實施例中，如第18圖與第19圖所示，黑色條紋圖案165在中心區塊可形成具有一致的寬度，且在上區塊與下區塊具有向顯示面板的最外側逐漸減少的寬度。利用這種配置，3D串擾可以被最小化。In an exemplary embodiment of the present invention, as shown in FIGS. 18 and 19, the black stripe pattern 165 may be formed to have a uniform width in the center block, and have a display panel in the upper block and the lower block. The outermost gradually decreasing width. With this configuration, 3D crosstalk can be minimized.

在本發明的示範性實施例中，如第20圖與第21圖所示，黑色條紋圖案165在中心區塊可形成具有一致的寬度，且在上區塊與下區塊具有向顯示面板的最外側逐漸增大的寬度。利用這種配置，亮度均勻度的減少可以被最小化。In an exemplary embodiment of the present invention, as shown in FIGS. 20 and 21, the black stripe pattern 165 may be formed to have a uniform width in the center block, and have a display panel in the upper block and the lower block. The outermost gradually increasing width. With this configuration, the reduction in brightness uniformity can be minimized.

前述的示範性實施例顯示了因為黑色條紋圖案與和其彼此對應的黑色矩陣圖案彼此完全重疊，所以黑色條紋圖案與黑色矩陣圖案於彼此互相平行的方向被排列成行，此時沒有考慮觀看位置。然而，黑色條紋圖案與和其彼此對應的黑色矩陣圖案可以在顯示面板的上部與下部彼此部分重疊，並且可以彼此偏斜地向顯示面板的中部，即觀看位置排列成行，以便保證所需的垂直視角以及改善亮度均勻度。The foregoing exemplary embodiment shows that since the black stripe pattern and the black matrix pattern corresponding to each other completely overlap each other, the black stripe pattern and the black matrix pattern are arranged in a line in a direction parallel to each other, and the viewing position is not considered at this time. However, the black stripe pattern and the black matrix pattern corresponding to each other may partially overlap each other at the upper and lower portions of the display panel, and may be aligned with each other obliquely toward the middle of the display panel, that is, the viewing position, in order to ensure the required vertical. Angle of view and improved brightness uniformity.

第22圖為顯示偏斜地向顯示面板的中部排列成行的黑色條紋圖案與黑色矩陣圖案的實例的視圖。第23圖為顯示依據第22圖在顯示面板中部被展寬的可視範圍的視圖。Fig. 22 is a view showing an example of a black stripe pattern and a black matrix pattern which are arranged obliquely in the middle of the display panel in a row. Fig. 23 is a view showing a visible range which is widened in the middle of the display panel in accordance with Fig. 22.

參考第22圖，為了展寬相對於顯示面板中部的可視範圍，圖案相位差膜180的整體垂直間距P1可以設計為小於像素陣列的整體垂直間距P2。在這種狀態下，當圖案相位差膜180與像素陣列相對於它們的中心排列成行的時候，黑色條紋圖案165與黑色矩陣圖案130被偏斜地從顯示面板的上部與下部向與觀看位置對應的中部排列成行。Referring to Fig. 22, in order to broaden the visible range with respect to the middle of the display panel, the overall vertical pitch P1 of the pattern retardation film 180 may be designed to be smaller than the entire vertical pitch P2 of the pixel array. In this state, when the pattern phase difference film 180 and the pixel array are arranged in a row with respect to their centers, the black stripe pattern 165 and the black matrix pattern 130 are obliquely shifted from the upper and lower portions of the display panel to the viewing position. The middle of the line is arranged in a row.

由上述不同間距設計以及斜排列而帶來的可視區域對應於如第23圖所示的三個實線區域之間的重疊部分。這裏，該可視區域指的是3D串擾的值在10%以下時所顯示的立體影像顯示器100影像的區域，是不需要考慮到顯示位置。同時，由相等間距設計(P1=P2)而帶來的可視區域對應於如第23圖所示的虛線區域之間的重疊部分。通過第23圖可以清楚地看到，由所述不同間距設計而帶來的可視區域比由相等間距設計而帶來的可視區域寬得多。可視區域一旦被展寬，就改善了亮度均勻度並減少了3D串擾。The visible area resulting from the above-described different pitch design and oblique arrangement corresponds to the overlapping portion between the three solid line areas as shown in FIG. Here, the viewable area refers to an area of the image of the stereoscopic image display 100 displayed when the value of the 3D crosstalk is 10% or less, and it is not necessary to consider the display position. At the same time, the visible area brought about by the equal pitch design (P1 = P2) corresponds to the overlapping portion between the broken line areas as shown in Fig. 23. As can be clearly seen from Fig. 23, the viewable area resulting from the different pitch designs is much wider than the viewable area resulting from the equal pitch design. Once the viewable area is widened, brightness uniformity is improved and 3D crosstalk is reduced.

第24圖至第28圖是關於提供不同間距設計與斜排列以改善亮度均勻度並減少3D串擾的本發明示範性實施例。Figures 24 through 28 are diagrams of exemplary embodiments of the present invention that provide different pitch designs and oblique alignments to improve brightness uniformity and reduce 3D crosstalk.

第24圖至第26圖為顯示將不同間距設計應用到第9圖、第11圖、第15圖中之本發明的偏光眼鏡型立體影像顯示器的視圖。第27圖與第28圖為顯示將不同間距設計應用到第18圖、第20圖中之本發明的偏光眼鏡型立體影像顯示器的視圖。Figs. 24 to 26 are views showing a polarized glasses type stereoscopic image display of the present invention in which different pitch designs are applied to Figs. 9, 11 and 15. Figs. 27 and 28 are views showing a polarized glasses type stereoscopic image display of the present invention in which different pitch designs are applied to Figs. 18 and 20.

參考第24圖至第28圖，上述不同間距設計與斜排列允許黑色條紋圖案165與黑色矩陣圖案130偏斜地從顯示面板的上部與下部向對應於觀看位置的中部排列成行。利用這種配置，本發明使在不考慮面板大小及其解析度的情況下改善亮度均勻度以及加寬相對於顯示面板的中部的可視範圍至一所需範圍成為可能。Referring to FIGS. 24 to 28, the above-described different pitch design and oblique arrangement allow the black stripe pattern 165 and the black matrix pattern 130 to be aligned in a row from the upper portion and the lower portion of the display panel to the middle portion corresponding to the viewing position. With this configuration, the present invention makes it possible to improve the brightness uniformity and widen the visible range with respect to the middle portion of the display panel to a desired range without considering the panel size and its resolution.

如上所述，依據本發明的偏光眼鏡型立體影像顯示器藉由形成黑色矩陣圖案與黑色條紋圖案以對應於與其彼此相對的濾色片基板的兩邊，使為了讓孔徑比與亮度的減少最小化而相比於先前技術降低黑色矩陣圖案的寬度以及實現與先前技術相同的垂直視角成為可能。As described above, the polarized glasses type stereoscopic image display according to the present invention forms a black matrix pattern and a black stripe pattern to correspond to both sides of the color filter substrate opposed to each other, so as to minimize the reduction in aperture ratio and brightness. It is possible to reduce the width of the black matrix pattern and achieve the same vertical viewing angle as the prior art compared to the prior art.

而且，本發明藉由根據顯示位置而改變黑色條紋圖案寬度的方式，對展寬垂直視角以及降低由每個位置上的視角決定的亮度均勻度的減少作出了貢獻。Moreover, the present invention contributes to the widening of the vertical viewing angle and the reduction of the brightness uniformity determined by the viewing angle at each position by changing the width of the black stripe pattern according to the display position.

更進一步地，本發明藉由設計圖案相位差膜的整體垂直間距使其小於像素陣列的整體垂直間距並且從顯示面板的上部與下部向對應於觀看位置的中部偏斜地將黑色條紋圖案與黑色矩陣排列成行的方式，對在不考慮面板大小及其解析度的情況下改善亮度均勻度以及加寬相對於顯示面板中部的可視範圍至一所需的範圍作出了貢獻。Furthermore, the present invention makes the black stripe pattern and black from the upper and lower portions of the display panel obliquely from the upper portion and the lower portion of the display panel to the middle portion corresponding to the viewing position by designing the overall vertical pitch of the pattern retardation film to be smaller than the overall vertical pitch of the pixel array. The arrangement of the matrices in a row contributes to improving brightness uniformity and widening the visible range relative to the middle of the display panel to a desired range without regard to panel size and resolution.

綜上所述，應當理解的是本領域技術人員可以做出各種改變以及修飾，但這些改變及修飾均沒有脫離本發明的技術範圍。因此，本發明的技術範圍不應當被限制在說明書的具體實施方式，而應被限定於申請專利範圍中。In view of the above, it should be understood that various changes and modifications may be made by those skilled in the art without departing from the scope of the invention. Therefore, the technical scope of the present invention should not be limited to the specific embodiments of the specification, but should be limited to the scope of the patent application.
