Description

垂直排列型液晶顯示模組Vertical Alignment LCD Module

本發明是有關於一種顯示模組，且特別是有關於一種垂直排列型液晶顯示模組。The present invention relates to a display module, and in particular to a vertically aligned liquid crystal display module.

在液晶顯示器運作時，雖然使用垂直排列（vertical alignment, VA）或橫向電場效應（in-plane switching, IPS）等廣視角等技術中，使用補償膜或相位差膜等材料來補償大視角之顏色偏誤，但因訊號出射角不同而無法完美補償。雖然大視角的顏色因補償膜或相位差膜已作部分修正，但仍有程度不同之顏色訊號偏誤，其中以扭曲向列型（twisted nematic, TN）及VA技術最為嚴重。In the operation of liquid crystal displays, although technologies such as vertical alignment (VA) or in-plane switching (IPS) are used for wide viewing angles, materials such as compensation films or retardation films are used to compensate the color of large viewing angles. Bias, but it cannot be perfectly compensated due to different signal exit angles. Although the color of the large viewing angle has been partially corrected by the compensation film or retardation film, there are still different degrees of color signal deviation, among which twisted nematic (TN) and VA technology are the most serious.

若以顯示器各視角的紅、綠及藍色彩穩定度來看，可以發現VA的顯示技術即使加上補償膜，仍然可以發現在大於45度視角時，會有嚴重之色偏現象，即會有偏綠泛白之問題，尤以膚色畫面為甚。如此一來，造成許多品牌業者在高階產品不願使用VA技術。If we look at the red, green and blue color stability at different viewing angles of the display, we can find that even if the VA display technology is added with a compensation film, it can still be found that there will be serious color shift when the viewing angle is greater than 45 degrees, that is, there will be The problem of greenish and white, especially in the skin color picture. As a result, many brand owners are reluctant to use VA technology in high-end products.

然而，VA技術仍有正視角高對比之顯色性強之優點，因此如何改善VA液晶顯示器的大視角色偏問題，是可以投入的研發方向。However, VA technology still has the advantages of high front viewing angle, high contrast and strong color rendering. Therefore, how to improve the problem of large viewing angle deviation of VA liquid crystal display is a research and development direction that can be invested.

在本發明的實施例的垂直排列型液晶顯示模組中，由於採用影像色彩調整膜來讓大視角的可見光穿透光譜的短波長的一端的平均穿透率小於在可見光穿透光譜的長波長的一端的平均穿透率，因此可以有效改善大視角時畫面偏綠泛白或偏藍泛白之問題，進而改善膚色畫面的顏色準確度。也就是說，本發明的實施例的垂直排列型液晶顯示模組能夠有效改善大視角色偏的問題。In the vertically aligned liquid crystal display module of the embodiment of the present invention, since the image color adjustment film is used to allow the average transmittance at one end of the short-wavelength end of the visible light transmission spectrum with a large viewing angle to be smaller than that at the long-wavelength end of the visible light transmission spectrum Therefore, it can effectively improve the problem of greenish or bluish whitening of the picture at large viewing angles, thereby improving the color accuracy of the skin tone picture.

FIG. 2 is an optical simulation transmittance spectrum diagram of the image color adjustment film 300 of two embodiments of the present invention when the viewing angle is 75 degrees. Please refer to FIG. 1A , FIG. 1B and FIG. 2 , the image color adjustment film 300 can adjust the original hue and frequency spectrum at various viewing angles, and has the following optical characteristics for the large viewing angle of the vertical alignment liquid crystal panel 200 . Specifically, the image color adjustment film 300 has the following optical characteristics in each viewing direction between 60 degrees and 75 degrees from its normal line: at one end E1 of the short wavelength of the visible light transmission spectrum of the image color adjustment film 300 The average transmittance is less than the average transmittance of E2 at one end of the long wavelength end of the visible light transmission spectrum. In this embodiment, the average transmittance at one end E1 of the short-wavelength end E1 of the visible light transmission spectrum of the image color adjustment film 300 refers to the average transmittance corresponding to the wavelength of 300 nm to 495 nm, and The average transmittance at the long-wavelength end E2 of the visible light transmission spectrum of the image color adjustment film 300 refers to the average transmittance corresponding to 570 nm to 750 nm. In FIG. 2 , the two transmittance spectral curves of the dotted line and the solid line belong to two different embodiments.

在本實施例的垂直排列型液晶顯示模組100中，由於採用影像色彩調整膜300來讓大視角的可見光穿透光譜的短波長的一端E1的平均穿透率小於在可見光穿透光譜的長波長的一端E2的平均穿透率，也就是讓較多的紅光與黃光通過，並抑制部分藍光與綠光通過，因此可以有效改善大視角時畫面偏綠泛白或偏藍泛白之問題，進而改善膚色畫面的顏色準確度。也就是說，本實施例的垂直排列型液晶顯示模組100能夠有效改善大視角色偏的問題。此外，垂直排列型液晶顯示技術仍有正視角高對比之顯色性強之優點，本實施例能夠改善大視角色偏且保留垂直排列型液晶顯示技術高對比特性，就可以超越IPS技術而變成顯色效果更優越之顯示技術。In the vertically aligned liquid crystal display module 100 of this embodiment, since the image color adjustment film 300 is used to allow the visible light with a large viewing angle to transmit the spectrum, the average transmittance at the short wavelength end E1 is smaller than that at the long end of the visible light transmittance spectrum. The average transmittance of E2 at one end of the wavelength is to allow more red light and yellow light to pass through, and to suppress part of the blue light and green light to pass through, so it can effectively improve the greenish white or blueish white of the screen when the viewing angle is large. problem, thereby improving the color accuracy of the skin tones picture.

The problem of greenish white or bluish whitening can be solved, thereby improving the color accuracy of skin tones images. In this embodiment, the ratio of the blue light, green light and red light components refers to the ratio of the areas of the blue light, green light and red light under the spectral curve.

圖1D為圖1C的垂直排列型液晶顯示模組的平行偏振光與垂直偏振光的立體示意圖。請參照圖1C與圖1D，在本實施例中，偏光板110的穿透軸X1平行於垂直排列型液晶面板200的短邊方向，而偏光板120的穿透軸X2例如是平行於垂直排列型液晶面板200的長邊方向，其中穿透軸X1與穿透軸X2彼此垂直（如圖1C所繪示）。若偏光板110之穿透軸X1為垂直於垂直排列型液晶面板200的長邊方向（此長邊方向例如平行於桌面方向），則在垂直排列型液晶顯示模組100水平方向之大視角可觀察得到垂直偏振光。其中，若以來自背光模組400的入射光50、反射光52所形成的一平面PLN來看，僅有可符合偏光板110的穿透軸X1且偏振方向PS垂直於平面PLN之偏振光（即垂直偏振光）可以穿透。因此，在干涉設計上，可以垂直偏振光來設計影像色彩調整膜300的參數（例如膜厚、折射率等），也就是專為垂直偏振光量身訂作而以上述的方式來調整其光譜，使其具有上述光學特性。其中，部分的入射光50穿過偏光板120、垂直排列型液晶面板200、偏光板110及影像色彩調整膜300而成為透射光54，而部分入射光50則被影像色彩調整膜300反射成反射光52。然而，在另一實施例中，則是影像色彩調整膜300位於偏光板120之上，若其穿透軸X2為平行於垂直排列型液晶面板200的短邊方向（此短邊方向垂直於桌面），入射光50從背光模組400射入垂直排列型液晶面板200後，碰到影像色彩調整膜300後產生反射光52，入射光50與反射光52形成平面PLN，則偏振方向PS垂直於平面PLN之偏振光可以大部分穿透穿透軸X2，則影像色彩調整膜300則同樣以垂直偏振方向PS來設計。反之，若是穿透軸X2的方向為平行於垂直排列型液晶面板200的長邊方向且影像色彩調整膜300位於偏光板120之上，同樣在水平大視角的影像調整上，則以平行偏振方向PP來設計（其中平行偏振方向PP平行於平面PLN，且偏振方向PP平行於平面PLN的偏振光稱為平行偏振光）。一般而言，當影像色彩調整膜300的參數依據垂直偏振光來設計時會比較好設計，且可以用較少的膜層數量就能夠達到良好的上述光學特性。FIG. 1D is a three-dimensional schematic diagram of parallel polarized light and vertical polarized light of the vertically aligned liquid crystal display module in FIG. 1C . Please refer to FIG. 1C and FIG. 1D. In this embodiment, the transmission axis X1 of the polarizer 110 is parallel to the short side direction of the vertical alignment liquid crystal panel 200, and the transmission axis X2 of the polarizer 120 is, for example, parallel to the vertical alignment. The longitudinal direction of the type liquid crystal panel 200 , wherein the transmission axis X1 and the transmission axis X2 are perpendicular to each other (as shown in FIG. 1C ). If the transmission axis X1 of the polarizer 110 is perpendicular to the long side direction of the vertical alignment type liquid crystal panel 200 (the long side direction is parallel to the desktop direction, for example), then the large viewing angle in the horizontal direction of the vertical alignment type liquid crystal display module 100 can be Vertically polarized light is observed. Among them, if viewed from the plane PLN formed by the incident light 50 and reflected light 52 from the backlight module 400, there are only polarized lights that can meet the transmission axis X1 of the polarizer 110 and whose polarization direction PS is perpendicular to the plane PLN ( That is, vertically polarized light) can pass through. Therefore, in terms of interference design, the parameters of the image color adjustment film 300 (such as film thickness, refractive index, etc.) can be designed for vertically polarized light, that is, it is tailored for vertically polarized light and its spectrum can be adjusted in the above-mentioned manner , so that it has the above-mentioned optical properties. Wherein, part of the incident light 50 passes through the polarizer 120, the vertically aligned liquid crystal panel 200, the polarizer 110, and the image color adjustment film 300 to become the transmitted light 54, and part of the incident light 50 is reflected by the image color adjustment film 300 to become a reflection Light 52. However, in another embodiment, the image color adjustment film 300 is located on the polarizer 120, if its transmission axis X2 is parallel to the short side direction of the vertically aligned liquid crystal panel 200 (the short side direction is perpendicular to the desktop ), after the incident light 50 enters the vertical alignment liquid crystal panel 200 from the backlight module 400, and hits the image color adjustment film 300, the reflected light 52 is generated. The incident light 50 and the reflected light 52 form a plane PLN, and the polarization direction PS is perpendicular to The polarized light of the plane PLN can mostly pass through the transmission axis X2, and the image color adjustment film 300 is also designed with the vertical polarization direction PS. On the contrary, if the direction of the transmission axis X2 is parallel to the long side direction of the vertically aligned liquid crystal panel 200 and the image color adjustment film 300 is located on the polarizer 120, also in the image adjustment of the horizontal large viewing angle, the parallel polarization direction PP (where the parallel polarization direction PP is parallel to the plane PLN, and the polarized light whose polarization direction PP is parallel to the plane PLN is called parallel polarized light). Generally speaking, when the parameters of the image color adjustment film 300 are designed according to the vertically polarized light, it is better to design, and the above-mentioned good optical properties can be achieved with fewer film layers.

圖4為本發明的另一實施例的垂直排列型液晶顯示模組的剖面示意圖。本實施例的垂直排列型液晶顯示模組100a與圖1A的垂直排列型液晶顯示模組100類似，而兩者的差異在於在圖1A的垂直排列型液晶顯示模組100中，第一透光膜310及第二透光膜320是形成於偏光板110上。然而，在本實施例的垂直排列型液晶顯示模組100a中，影像色彩調整膜300的第一透光膜310及第二透光膜320是先形成於透光基材330上，然後透光基材330再透過膠材340貼附於偏光板110上。FIG. 4 is a schematic cross-sectional view of a vertically aligned liquid crystal display module according to another embodiment of the present invention. The vertical alignment liquid crystal display module 100a of this embodiment is similar to the vertical alignment liquid crystal display module 100 of FIG. 1A, and the difference between the two is that in the vertical alignment liquid crystal display module 100 of FIG. The film 310 and the second transparent film 320 are formed on the polarizer 110 . However, in the vertical alignment liquid crystal display module 100a of this embodiment, the first light-transmitting film 310 and the second light-transmitting film 320 of the image color adjustment film 300 are formed on the light-transmitting substrate 330 first, and then light-transmitting The base material 330 is attached to the polarizer 110 through the adhesive material 340 .

圖5為本發明的又一實施例的垂直排列型液晶顯示模組的剖面示意圖。請參照圖5本實施例的垂直排列型液晶顯示模組100b與圖1A的垂直排列型液晶顯示模組100類似，而兩者的差異如下所述。在圖1A的垂直排列型液晶顯示模組100中，影像色彩調整膜300是配置於偏光板110外側，然而，在本實施例的垂直排列型液晶顯示模組100b中，影像色彩調整膜300可以整合至偏光板110內部。具體而言，在本實施例中，影像色彩調整膜300配置於第一透明基材112與垂直排列型液晶面板200之間，第二透明基材114配置於影像色彩調整膜300與垂直排列型液晶面板200之間，偏光層116配置於影像色彩調整膜300與第二透明基材114之間，且相位差補償膜118配置於偏光層116與第二透明基材114之間。FIG. 5 is a schematic cross-sectional view of a vertical alignment liquid crystal display module according to another embodiment of the present invention. Please refer to FIG. 5 . The vertical alignment liquid crystal display module 100 b of this embodiment is similar to the vertical alignment liquid crystal display module 100 of FIG. 1A , and the differences between the two are as follows. In the vertical alignment type liquid crystal display module 100 of FIG. 1A , the image color adjustment film 300 is arranged outside the polarizer 110, however, in the vertical alignment type liquid crystal display module 100b of this embodiment, the image color adjustment film 300 can be integrated into the inside of the polarizer 110 . Specifically, in this embodiment, the image color adjustment film 300 is arranged between the first transparent substrate 112 and the vertical alignment type liquid crystal panel 200, and the second transparent substrate 114 is arranged between the image color adjustment film 300 and the vertical alignment type liquid crystal panel 200. Between the liquid crystal panels 200 , the polarizing layer 116 is disposed between the image color adjustment film 300 and the second transparent substrate 114 , and the retardation compensation film 118 is disposed between the polarizing layer 116 and the second transparent substrate 114 .

在本實施例中，影像色彩調整膜300的第一透光膜310與第二透光膜320的順序可上下對調，可以是第一透光膜310在第二透光膜320下，也可以是第二透光膜320在第一透光膜310下。In this embodiment, the order of the first light-transmitting film 310 and the second light-transmitting film 320 of the image color adjustment film 300 can be reversed up and down, the first light-transmitting film 310 can be under the second light-transmitting film 320, or The second transparent film 320 is under the first transparent film 310 .

第一透光膜310的折射率為1.6以下，且第二透光膜320的折射率為1.8至2.5。在本實施例中，第一透明基材112的折射率低於1.7。The refractive index of the first transparent film 310 is less than 1.6, and the refractive index of the second transparent film 320 is 1.8 to 2.5. In this embodiment, the refractive index of the first transparent substrate 112 is lower than 1.7.

在本實施例中，垂直排列型液晶顯示模組100b更包括一表面處理層119，其中第一透明基材112配置於表面處理層119與影像色彩調整膜300之間。舉例而言，表面處理層119的折射率低於1.5。表面處理層119例如為抗眩光層（anti-glare layer）、抗反射層（anti-reflection layer）或硬膜層（hard-coating layer）。In this embodiment, the vertical alignment liquid crystal display module 100 b further includes a surface treatment layer 119 , wherein the first transparent substrate 112 is disposed between the surface treatment layer 119 and the image color adjustment film 300 . For example, the refractive index of the surface treatment layer 119 is lower than 1.5. The surface treatment layer 119 is, for example, an anti-glare layer, an anti-reflection layer or a hard-coating layer.

此外，與圖1A的實施例相同的是，相位差補償膜118與第二透明基材114可合為一體，也就是第二透明基板114即為一相位差補償膜，而偏光板110b中可以不設置額外的相位差補償膜118。In addition, the same as the embodiment of FIG. 1A, the phase difference compensation film 118 and the second transparent substrate 114 can be integrated, that is, the second transparent substrate 114 is a phase difference compensation film, and the polarizer 110b can No additional retardation compensation film 118 is provided.

在本實施例中，偏光層116的穿透軸X1例如是平行於垂直排列型液晶面板200的短邊方向（即進入圖5的紙面的方向），因此在當使用者的眼睛在水平方向的大視角觀看垂直排列型液晶顯示模組100b，會看到垂直偏振光，若將大視角的入射光50及反射光52設為平面PLN來看（請參照圖1D），受制於垂直排列型液晶顯示模組100b之偏光板110之穿透軸X1為平行於垂直排列型液晶顯示模組100b的短邊方向，入射光50中僅偏振方向PS平行於短邊方向之偏振光可以大部分穿過垂直排列型液晶面板200，因此影像色彩調整膜300可以依據偏光板110之穿透軸X1方向來進行設計，以達到上述光學特性。然而，在其他實施例中，偏光層116的穿透軸X1也可以是平行於垂直排列型液晶面板200的長邊方向。In this embodiment, the transmission axis X1 of the polarizing layer 116 is, for example, parallel to the short side direction of the vertical alignment liquid crystal panel 200 (that is, the direction entering the paper of FIG. 5 ), so when the user's eyes are in the horizontal direction When looking at the vertically aligned liquid crystal display module 100b at a large viewing angle, you will see vertically polarized light. If the incident light 50 and the reflected light 52 at a large viewing angle are viewed as a plane PLN (please refer to FIG. 1D ), the vertically aligned liquid crystal The transmission axis X1 of the polarizer 110 of the display module 100b is parallel to the short side direction of the vertically aligned liquid crystal display module 100b, and among the incident light 50, only the polarized light whose polarization direction PS is parallel to the short side direction can mostly pass through For the vertically aligned liquid crystal panel 200 , the image color adjustment film 300 can be designed according to the direction of the transmission axis X1 of the polarizer 110 to achieve the above optical properties. However, in other embodiments, the transmission axis X1 of the polarizing layer 116 may also be parallel to the longitudinal direction of the vertically aligned liquid crystal panel 200 .

圖6A與圖6B為本發明的三個實施例的影像色彩調整膜在視角為60度時的反射率光譜與穿透率光譜。在圖6A與圖6B中，「H=60-70 nm/L=130-140 nm」是指此對應曲線是指影像色彩調整膜的第二透光膜320的膜厚為60奈米至70奈米且第一透光膜310的膜厚為130奈米至140奈米的光譜數據，其他曲線的意義以此類推。此外，在圖6A與圖6B中，第二透光膜320的折射率例如為1.8至2.4，而第一透光膜310的折射率例如為1.6至1.3。影像色彩調整膜的設計目標為以一般白光之穿透率光譜來看，在影像色彩調整膜的設計上，會使波長600～800奈米的光之平均穿透率大於400～600奈米的光之平均穿透率，以形成短波長穿透率低而長波長穿透率高的趨勢。6A and 6B are reflectance spectra and transmittance spectra of image color adjustment films of three embodiments of the present invention when the viewing angle is 60 degrees. In FIG. 6A and FIG. 6B, "H=60-70 nm/L=130-140 nm" means that this corresponding curve means that the film thickness of the second light-transmitting film 320 of the image color adjustment film is 60 nm to 70 nm. nanometer and the thickness of the first transparent film 310 is 130nm to 140nm, the meaning of other curves can be deduced by analogy. In addition, in FIG. 6A and FIG. 6B , the refractive index of the second transparent film 320 is, for example, 1.8 to 2.4, and the refractive index of the first transparent film 310 is, for example, 1.6 to 1.3. The design goal of the image color adjustment film is to look at the transmittance spectrum of general white light. In the design of the image color adjustment film, the average transmittance of light with a wavelength of 600-800 nm is greater than that of 400-600 nm. The average transmittance of light, in order to form a trend that the transmittance of short wavelength is low and the transmittance of long wavelength is high.

圖7是4區域垂直排列型液晶面板在未加上影像色彩調整膜時的紅光分量、綠光分量及藍光分量在多種不同視角的比例的折線圖。在本實施例中，藍光、綠光及紅光分量比例是指藍光、綠光及紅光在光譜曲線下方的面積的比例。圖8為圖4的垂直排列型液晶顯示模組中的影像色彩調整膜300與透光基材330在各種不同視角的反射率光譜。請參照圖4、圖7及圖8，本發明的實施例的影像色彩調整膜利用建設性干涉反射頻譜，設計「反射率相對高峰隨著視角增加往圖8左上方移動」作為主要設計重點。觀察垂直排列型液晶顯示面板之各個視角光譜分布，發現4區域垂直排列型液晶顯示面板在隨著視角增加紅光比例快速下降，而綠光與藍光比例上升，且8區域垂直排列型液晶顯示面板亦有類似問題。FIG. 7 is a broken-line diagram of ratios of red light components, green light components and blue light components at various viewing angles when the 4-area vertically aligned liquid crystal panel is not provided with an image color adjustment film. In this embodiment, the ratio of the blue light, green light and red light components refers to the ratio of the areas of the blue light, green light and red light under the spectral curve. FIG. 8 is a reflectance spectrum of the image color adjustment film 300 and the light-transmitting substrate 330 in the vertical alignment liquid crystal display module of FIG. 4 at various viewing angles. Please refer to FIG. 4, FIG. 7 and FIG. 8. The image color adjustment film of the embodiment of the present invention utilizes constructive interference reflection spectrum, and the design "relative peak of reflectance moves to the upper left of Fig. 8 with the increase of viewing angle" is the main design focus. Observing the spectral distribution of each viewing angle of the vertical alignment type liquid crystal display panel, it is found that the proportion of red light decreases rapidly with the increase of the viewing angle of the 4-area vertical alignment type liquid crystal display panel, while the ratio of green light and blue light increases, and the 8-area vertical alignment type liquid crystal display panel There are also similar problems.

在影像色彩調整膜中，利用薄膜（單層或是多層，每層膜厚約10～750 nm ) 之建設性干涉（constructive interference）之反射作用，在大視角反射藍光或部分綠光而由偏光板進入液晶顯示面板內部，使觀察者所觀察到的光譜，紅光相對能量比原有未有影像色彩調整膜時為高。因此，大視角的紅光比例調整成與正視角接近，以確認大視角的影像品質與正視角相近。In the image color adjustment film, the reflection of constructive interference (constructive interference) of the thin film (single layer or multi-layer, each layer thickness is about 10-750 nm) is used to reflect blue light or part of the green light at a large viewing angle and be polarized The plate enters the interior of the liquid crystal display panel, so that the spectrum and the relative energy of the red light observed by the observer are higher than those without the original image color adjustment film. Therefore, the red light ratio of the large viewing angle is adjusted to be close to the front viewing angle to confirm that the image quality of the large viewing angle is similar to that of the front viewing angle.

設計上，反射率光譜之設計較佳之實施例，是希望相對高峰區可隨視角增大會往左上（藍光方向)移動為最佳。反射率光譜之藍光帶波峰隨視角變大時，反射率光譜設計上可往左上方移動，其目的是使得觀察者從正視角往大視角移動時, 由於藍光及綠光削減比例逐漸拉高，影像色彩調整膜設計也逐步提高「削減藍光之能力」（或增加紅光與黃光之能量佔比之能力），在垂直排列型液晶顯示面板上使用，可反向調整大視角紅光、綠光及藍光能量佔比。In terms of design, a better embodiment of the design of the reflectance spectrum is to hope that the relative peak area can move to the upper left (blue light direction) as the viewing angle increases. When the peak of the blue light band of the reflectance spectrum increases with the angle of view, the design of the reflectance spectrum can move to the upper left. The design of the image color adjustment film also gradually improves the "ability to reduce blue light" (or increase the energy ratio of red light and yellow light). When used on vertically aligned liquid crystal display panels, it can reversely adjust the large viewing angle of red light, green light and Proportion of blue light energy.

為確保干涉效應能夠發生，若以單層膜為例，所形成之薄膜厚度為d，折射率為n，視角為θ，則n．d．cos θ=1/4．m．λ，其中m為奇數，λ為光之波長，其中θ的具體定義為使用者的眼睛的位置至垂直排列型液晶顯示模組的出光面的中心的連線與垂直排列型液晶顯示模組的法線的夾角。In order to ensure that the interference effect can occur, if a single-layer film is taken as an example, the thickness of the formed film is d, the refractive index is n, and the viewing angle is θ, then n. d. cos θ=1/4. m. λ, where m is an odd number, λ is the wavelength of light, where θ is specifically defined as the line connecting the position of the user's eyes to the center of the light-emitting surface of the vertical alignment liquid crystal display module and the vertical alignment liquid crystal display module The included angle of the normal.

在圖8的實施例中，第二透光膜320的折射率例如為2至2.4，而第一透光膜310的折射率例如為1.3至1.5。In the embodiment of FIG. 8 , the refractive index of the second transparent film 320 is, for example, 2 to 2.4, and the refractive index of the first transparent film 310 is, for example, 1.3 to 1.5.

Please refer to FIG. 10 , the vertical alignment liquid crystal display module 100 d of this embodiment is similar to the vertical alignment liquid crystal display module 100 b of FIG. 5 , and the differences between the two are as follows. In this embodiment, the image color adjustment film 300 is arranged between the second transparent substrate 114 and the vertical alignment type liquid crystal panel 200, that is, between the polarizer 110 and the vertical alignment type liquid crystal panel 200, and the image color adjustment The film 300 is disposed above the vertical alignment liquid crystal panel 200 .

圖11A為本發明又一實施例的垂直排列型液晶顯示模組的剖面示意圖，而圖11B為圖11A的垂直排列型液晶顯示模組的立體分層圖。請參照圖11A與圖11B，本實施例的垂直排列型液晶顯示模組100e與圖1A及圖1C的垂直排列型液晶顯示模組100類似，而兩者的差異如下所述。在本實施例的垂直排列型液晶顯示模組100e中，影像色彩調整膜300配置於垂直排列型液晶面板200的下方，而偏光板120配置於影像色彩調整膜300與垂直排列型液晶面板200之間，然而，在其他實施例中，也可以是影像色彩調整膜300配置於偏光板120與垂直排列型液晶面板200之間。11A is a schematic cross-sectional view of a vertical alignment liquid crystal display module according to another embodiment of the present invention, and FIG. 11B is a three-dimensional layered view of the vertical alignment liquid crystal display module of FIG. 11A . Please refer to FIG. 11A and FIG. 11B , the vertical alignment liquid crystal display module 100 e of this embodiment is similar to the vertical alignment liquid crystal display module 100 in FIG. 1A and FIG. 1C , and the differences between the two are as follows. In the vertical alignment type liquid crystal display module 100e of this embodiment, the image color adjustment film 300 is arranged under the vertical alignment type liquid crystal panel 200, and the polarizer 120 is arranged between the image color adjustment film 300 and the vertical alignment type liquid crystal panel 200. However, in other embodiments, the image color adjustment film 300 may also be disposed between the polarizer 120 and the vertical alignment liquid crystal panel 200 .

在本實施例中，偏光板120包括一第三透明基材122、一第四透明基材124及一偏光層126。第三透明基材122配置於垂直排列型液晶面板200下方，且第三透明基材122配置於垂直排列型液晶面板200與第四透明基材124之間。偏光層126配置於第三透明基材122與第四透明基材124之間。第三透明基材122與第四透明基材124可選用的材質可比照上述第一透明基材112與第二透明基材114可選用的材質，而偏光層126可選用的材質可比照上述偏光層116可選用的材質。In this embodiment, the polarizing plate 120 includes a third transparent substrate 122 , a fourth transparent substrate 124 and a polarizing layer 126 . The third transparent substrate 122 is disposed under the vertical alignment liquid crystal panel 200 , and the third transparent substrate 122 is disposed between the vertical alignment liquid crystal panel 200 and the fourth transparent substrate 124 . The polarizing layer 126 is disposed between the third transparent substrate 122 and the fourth transparent substrate 124 . The optional materials for the third transparent substrate 122 and the fourth transparent substrate 124 can be compared with the optional materials for the above-mentioned first transparent substrate 112 and the second transparent substrate 114, and the optional materials for the polarizing layer 126 can be compared with the above-mentioned polarized materials. Optional materials for layer 116.

在本實施例中，偏光板120的穿透軸X2（也就是偏光層126的穿透軸）平行於垂直排列型液晶面板200的短邊方向，因此對於水平方向大視角的光線而言，偏光板120允許來自影像色彩調整膜300的垂直偏振光通過，並阻擋來自影像色彩調整膜300的平行偏振光，故影像色彩調整膜300的參數可根據垂直偏振光來設計，以達到上述光學特性。當入射光50從背光模組400進入偏光板120時，若以入射光50與反射光52設為平面PLN（如圖1D所繪示）來看，入射光50中偏振方向PS之垂直於平面PLN之偏振光可大部分穿透偏光板120，而偏振方向PP平行於平面PLN之偏振光則為偏光板120所吸收，因此影像色彩調整膜300可為根據相對於平面PLN之垂直偏振光來設計，且膜層的數量可以較少就能夠達到上述光學特性。此外，將影像色彩調整膜300置於垂直排列型液晶面板200之下可提升垂直排列型液晶顯示模組100e的視覺品味，這是因為當垂直排列型液晶顯示模組100e不發光時，影像色彩調整膜300放置於下層將比較不容易反射外界的環境光，而讓使用者觀看到的螢幕呈現較黑的黑色，而提升了視覺品味。In this embodiment, the transmission axis X2 of the polarizing plate 120 (that is, the transmission axis of the polarizing layer 126) is parallel to the short side direction of the vertically aligned liquid crystal panel 200, so for light rays with a large viewing angle in the horizontal direction, the polarized light The plate 120 allows the vertically polarized light from the image color adjustment film 300 to pass through, and blocks the parallel polarized light from the image color adjustment film 300, so the parameters of the image color adjustment film 300 can be designed according to the vertically polarized light to achieve the above optical properties. When the incident light 50 enters the polarizing plate 120 from the backlight module 400, if the incident light 50 and the reflected light 52 are set as a plane PLN (as shown in FIG. 1D ), the polarization direction PS in the incident light 50 is perpendicular to the plane Most of the polarized light of PLN can pass through the polarizing plate 120, while the polarized light whose polarization direction PP is parallel to the plane PLN is absorbed by the polarizing plate 120, so the image color adjustment film 300 can be designed according to the vertical polarized light relative to the plane PLN , and the number of film layers can be less to achieve the above optical properties. In addition, placing the image color adjustment film 300 under the vertical alignment type liquid crystal panel 200 can improve the visual quality of the vertical alignment type liquid crystal display module 100e, because when the vertical alignment type liquid crystal display module 100e does not emit light, the image color When the adjustment film 300 is placed on the lower layer, it is less likely to reflect external ambient light, so that the screen displayed by the user is blacker, which improves the visual quality.

圖12為本發明再一實施例的垂直排列型液晶顯示模組的立體分層圖。請參照圖12，本實施例的垂直排列型液晶顯示模組100f與圖11A及圖11B的垂直排列型液晶顯示模組100e類似，而兩者的差異如下所述。在圖11A及圖11B的垂直排列型液晶顯示模組100e中，偏光板110的穿透軸X1平行於垂直排列型液晶面板200的長邊方向，而偏光板120的穿透軸X2平行於垂直排列型液晶面板200的短邊方向。與上述不同的是，在本實施例的垂直排列型液晶顯示模組100f中，偏光板110的穿透軸X1平行於垂直排列型液晶面板200的短邊方向，而偏光板120的穿透軸X2平行於垂直排列型液晶面板200的長邊方向。如此一來，此時偏光板120之穿透軸X2方向為平行於垂直排列型液晶面板200之長邊方向（長邊方向即水平方向），若以入射光50與反射光52為一平面PLN來看（請參照圖1D），其入射光50中偏振方向PP平行於平面PLN之偏振光可大部分穿透偏光板120，而偏振方向PS垂直於平面PLN的偏振光則被吸收，因此影像色彩調整膜300可根據相對於平面PLN之平行偏振光來設計，以達到上述光學特性。FIG. 12 is a three-dimensional layered view of a vertically aligned liquid crystal display module according to yet another embodiment of the present invention. Please refer to FIG. 12 , the vertical alignment liquid crystal display module 100 f of this embodiment is similar to the vertical alignment liquid crystal display module 100 e of FIGS. 11A and 11B , and the differences between the two are as follows. In the vertical alignment liquid crystal display module 100e shown in FIG. 11A and FIG. 11B, the transmission axis X1 of the polarizer 110 is parallel to the long side direction of the vertical alignment liquid crystal panel 200, and the transmission axis X2 of the polarizer 120 is parallel to the vertical direction. The short side direction of the alignment type liquid crystal panel 200 . Different from the above, in the vertical alignment liquid crystal display module 100f of this embodiment, the transmission axis X1 of the polarizer 110 is parallel to the short side direction of the vertical alignment liquid crystal panel 200, and the transmission axis X1 of the polarizer 120 is X2 is parallel to the long side direction of the vertical alignment liquid crystal panel 200 . In this way, the direction of the transmission axis X2 of the polarizer 120 is parallel to the long side direction of the vertically aligned liquid crystal panel 200 (the long side direction is the horizontal direction). If the incident light 50 and the reflected light 52 are regarded as a plane PLN See (please refer to FIG. 1D ), among the incident light 50, the polarized light whose polarization direction PP is parallel to the plane PLN can mostly pass through the polarizer 120, while the polarized light whose polarization direction PS is perpendicular to the plane PLN is absorbed, so the image color The adjustment film 300 can be designed according to the parallel polarized light relative to the plane PLN to achieve the above optical properties.

圖15為對照組、圖1A實施例及圖5實施例的垂直排列型液晶顯示模組當紅色、綠色及藍色子畫素都點亮時於60度視角的實際光譜圖。在圖15中，對照組的曲線是不具有本發明的實施例的影像色彩調整膜的垂直排列型液晶顯示模組。由圖15可明顯看出，圖1A實施例的垂直排列型液晶顯示模組100及圖5實施例的垂直排列型液晶顯示模組100b的紅光（長波長部分）的光譜強度明顯高出對照組的紅光的光譜強度，代表在60度視角時，膚色之紅光與黃光之能量占比均提昇（其中黃光波段是指波長約為570奈米至590奈米的波段），有效提升大視角影像的色彩品質。FIG. 15 is the actual spectrum diagram of the control group, the embodiment in FIG. 1A and the embodiment in FIG. 5 at a viewing angle of 60 degrees when the red, green and blue sub-pixels are all lit up. In FIG. 15 , the curve of the control group is a vertical alignment liquid crystal display module without the image color adjustment film of the embodiment of the present invention. It can be clearly seen from FIG. 15 that the spectral intensity of the red light (long wavelength part) of the vertical alignment liquid crystal display module 100 of the embodiment in FIG. 1A and the vertical alignment liquid crystal display module 100b of the embodiment of FIG. 5 is significantly higher than that of the control The spectral intensity of the red light in the group means that at a viewing angle of 60 degrees, the energy ratio of the red light and yellow light of the skin color is increased (the yellow light band refers to the band with a wavelength of about 570 nm to 590 nm), which effectively improves the The color quality of the perspective image.

綜上所述，在本發明的實施例的垂直排列型液晶顯示模組中，由於採用影像色彩調整膜來讓大視角的可見光穿透光譜的短波長的一端的平均穿透率小於在可見光穿透光譜的長波長的一端的平均穿透率，也就是讓較多的紅光與黃光通過，並抑制藍光與綠光通過，因此可以有效改善大視角時畫面偏綠泛白或偏藍泛白之問題，進而改善膚色畫面的顏色準確度。也就是說，本發明的實施例的垂直排列型液晶顯示模組能夠有效改善大視角色偏的問題。此外，垂直排列型液晶顯示技術仍有正視角高對比之顯色性強之優點，本發明的實施例能夠改善大視角色偏且保留垂直排列型液晶顯示技術高對比特性，就可以超越IPS技術而變成顯色效果更優越之顯示技術。To sum up, in the vertically aligned liquid crystal display module of the embodiment of the present invention, since the image color adjustment film is used to allow the visible light with a large viewing angle to penetrate the short-wavelength end of the spectrum, the average transmittance is lower than that at the end of the visible light transmittance. The average transmittance of the long-wavelength end of the transmission spectrum is to allow more red light and yellow light to pass through, and to suppress the passage of blue light and green light, so it can effectively improve the greenish white or blueish color of the screen when the viewing angle is large. The problem of whiteness can be solved, thereby improving the color accuracy of the skin tones picture. That is to say, the vertically aligned liquid crystal display module of the embodiment of the present invention can effectively solve the problem of large viewing angle deviation. In addition, the vertical alignment liquid crystal display technology still has the advantages of high contrast and strong color rendering at the front viewing angle. The embodiment of the present invention can improve the large viewing angle deviation and retain the high contrast characteristics of the vertical alignment liquid crystal display technology, which can surpass the IPS technology And become a display technology with superior color rendering effect.
