In detail, the light-shielding unit 3 is disposed on the light-emitting side 211 of the display unit 2 , and is determined by the angle between the absorption axes of the polarizing layer 22 disposed on the light-emitting side 211 and the linear polarizing film 31 of the light-shielding unit 3 . It is not greater than 45 degrees to ensure that the total transmittance of light passing through the stacked linear polarizing film 31 and the polarizing layer 22 is not less than 45% when the display unit 2 is activated. Preferably, the included angle between the absorption axis of the linear polarizing film 31 and the absorption axis of the polarizing layer 22 adjacent to the display unit 2 (equivalent to the included angle I in FIG. 2 ) is between 30 degrees and 45 degrees, and the light passes through the phase. The total transmittance of the stacked linear polarizing film 31 and the polarizing layer 22 is between 45% and 68%, which can avoid the problem of insufficient brightness.

該抗反射單元4具有可透光性，並包括一設置在該遮光單元3反向於該顯示單元2一側的保護層41，及一設置在該保護層41上的抗反射層42。在本實施例中，該保護層41選自一玻璃蓋板，而該抗反射層42選自一表面塗佈有一抗眩硬化層(Anti glare-hard coating，AGHC)的對苯二甲酸乙二酯(PET)薄膜。該保護層41覆蓋於該線偏光膜31上，以避免該線偏光膜31毀損或自該顯示單元2脫落。該抗反射層42可減緩自該顯示單元2發出的光線發生內反射的情形，進而提高出光率，並提升該顯示模組所顯示影像的亮度、色度或對比值。The anti-reflection unit 4 has light transmittance, and includes a protective layer 41 disposed on the side of the shading unit 3 opposite to the display unit 2 , and an anti-reflection layer 42 disposed on the protective layer 41 . In this embodiment, the protective layer 41 is selected from a glass cover plate, and the anti-reflection layer 42 is selected from a surface of ethylene terephthalate coated with an anti-glare-hard coating (AGHC). Ester (PET) film. The protective layer 41 covers the linear polarizing film 31 to prevent the linear polarizing film 31 from being damaged or falling off from the display unit 2 . The anti-reflection layer 42 can slow down the internal reflection of the light emitted from the display unit 2 , thereby increasing the light extraction rate and improving the brightness, chromaticity or contrast of the image displayed by the display module.

詳細地說，由於自該顯示層21用於顯示出光的一面疊置了由具有不同折射率的材質所構成的該偏光層22、該線偏光膜31，以及該保護層41，而光線在通過不同材質的膜層界面時會發生不同程度的內反射與折射，而對該顯示單元2的顯示影像造成干擾(例如：色度、亮度或是對比值)。因此，本新型藉由設置該抗反射層42，使光線通過該抗反射層42，所造成的反射光對其他的反射光產生破壞性干涉，進而抵消不同膜層間反射光所造成的影響。In detail, since the polarizing layer 22, the linear polarizing film 31, and the protective layer 41 made of materials with different refractive indices are stacked from the side of the display layer 21 for displaying light, the light passes through Different degrees of internal reflection and refraction will occur at the interface of the film layers of different materials, which will interfere with the displayed image of the display unit 2 (eg, chromaticity, brightness or contrast). Therefore, by disposing the anti-reflection layer 42 in the present invention, the light passes through the anti-reflection layer 42, and the reflected light causes destructive interference to other reflected light, thereby offsetting the influence of the reflected light between different film layers.

該接合單元5包括一用以黏接該顯示單元2與該遮光單元3的第一接合層51，及一用以黏接該遮光單元3與該抗反射單元4的第二接合層52。本實施例中，該第一接合層51選自液態光學膠(Liquid optical clear adhesive，LOCA)，該第二接合層52選自感壓型黏著劑(Pressure sensitive adhesive，PSA)。The bonding unit 5 includes a first bonding layer 51 for bonding the display unit 2 and the light-shielding unit 3 , and a second bonding layer 52 for bonding the light-shielding unit 3 and the anti-reflection unit 4 . In this embodiment, the first bonding layer 51 is selected from liquid optical clear adhesive (LOCA), and the second bonding layer 52 is selected from pressure sensitive adhesive (PSA).

要說明的是，於一些實施例中，也可依需求僅設置該遮光單元3在該顯示單元2上，而無須設置該接合單元5及/或抗反射單元4。It should be noted that, in some embodiments, only the shading unit 3 may be provided on the display unit 2 as required, and the bonding unit 5 and/or the anti-reflection unit 4 need not be provided.

茲將前述該顯示模組在未顯示影像時(即該顯示單元2未啟動時)，進行色度值檢測，並將色度值檢測結果整理於表1。Herein, when the display module is not displaying an image (ie, when the display unit 2 is not activated), the chromaticity value detection is performed, and the chromaticity value detection results are arranged in Table 1.

在本實施例中，該色度值檢測是利用一分光式色差儀(Spectrophotometer，型號：CM700d，Konica Minolta)自該顯示模組靠近該遮光單元3的一面，並分別對應該可視區VA與該非可視區NA的位置進行量測，且在相同的位置分別以包含鏡面正反射光(Specular component include，SCI)模式，以及排除鏡面正反射光(Specular component exclude，SCE)模式兩種色度模式進行色度值檢測，而得到其色度值L、a、b。其中，色度值L代表亮度(數值越高，代表顏色越亮白)；色度值a代表紅綠色度(數值越高，代表顏色越偏向紅色(+)，數值越低，顏色越偏向綠色(-))；色度值b代表黃藍色度(數值越高，代表顏色越偏向黃色(+)，數值越低，顏色越偏向藍色(-))。In this embodiment, the chromaticity value is detected by using a spectrophotometer (Spectrophotometer, model: CM700d, Konica Minolta) from the display module close to the shading unit 3, and corresponding to the visible area VA and the non-contact area respectively. The position of the visible area NA is measured, and at the same position, the two chromaticity modes, the Specular component include (SCI) mode and the Specular component exclude (SCE) mode, are used respectively. The chromaticity value is detected, and its chromaticity value L, a, b is obtained. Among them, the chromaticity value L represents the brightness (the higher the value, the brighter the color is); the chromaticity value a represents the red-green degree (the higher the value, the more red (+) the color is, the lower the value, the more green the color is. (-)); the chromaticity value b represents the degree of yellow-blue (the higher the value, the more yellow (+) the color is, the lower the value, the more blue (-) the color is).

接著，再將分別於該可視區VA與該非可視區NA所測得的色度值(L、a、b)依照公式：△E=

進行計算，而得到一△E值，該△E值表示該顯示模組在該可視區VA與該非可視區NA所呈現的顏色差異。 Then, according to the formula: △E=

The calculation is performed to obtain a ΔE value, and the ΔE value represents the color difference presented by the display module in the visible area VA and the non-visible area NA.

表1 SCI SCE 可視區 L 9.86 2.20 a -1.3 -0.19 b -1.22 -0.91 非可視區 L 9.96 2.50 a -0.71 -0.17 b -0.84 -1.06 △E值 0.71 0.34 Table 1 SCI SCE viewable area L 9.86 2.20 a -1.3 -0.19 b -1.22 -0.91 non-visible area L 9.96 2.50 a -0.71 -0.17 b -0.84 -1.06 △E value 0.71 0.34

在本實施例中，該顯示模組透過該分光式色差儀是以兩種不同的色度模式(即包含鏡面正反射光模式，以及排除鏡面正反射光模式)進行色度值檢測，所測得該可視區VA與該非可視區NA的△E值皆不大於2，即可達到一體黑的視覺效果，而由表1可以得知，在該顯示單元2未啟動的情況下，兩個區域的顏色差異極小(兩種色度模式下所測得的△E值皆小於1)，而不易由肉眼區分出該可視區VA與該非可視區NA，因此本實施例的顯示模組具有良好的一體黑的視覺效果。In this embodiment, the display module performs chromaticity value detection through the spectrophotometer in two different chromaticity modes (that is, the specular specular reflection mode is included, and the specular specular reflection mode is excluded). It is obtained that the ΔE values of the visible area VA and the non-visible area NA are both not greater than 2, and the visual effect of one black can be achieved, and it can be known from Table 1 that when the display unit 2 is not activated, the two areas are The color difference is very small (the ΔE values measured in the two chromaticity modes are all less than 1), and it is difficult to distinguish the visible area VA and the non-visual area NA by the naked eye, so the display module of this embodiment has a good One black visual effect.

綜上所述，藉由在該顯示單元2上設置該線偏光膜31，且該線偏光膜31的吸收軸與該顯示單元2相鄰的偏光層22的吸收軸的夾角不大於45度，而令該線偏光膜31與相鄰的該偏光層22在該顯示單元2啟動時的能維持良好的穿透率，且在該顯示單元2未啟動時，該可視區VA與該非可視區NA的顏色差異極小，而達到一體黑的視覺效果，故確實能達成本新型的目的。To sum up, by disposing the linear polarizing film 31 on the display unit 2, and the included angle between the absorption axis of the linear polarizing film 31 and the absorption axis of the polarizing layer 22 adjacent to the display unit 2 is not greater than 45 degrees, So that the linear polarizing film 31 and the adjacent polarizing layer 22 can maintain good transmittance when the display unit 2 is activated, and when the display unit 2 is not activated, the visible area VA and the non-visual area NA The color difference is very small, and the visual effect of one black is achieved, so it can indeed achieve the purpose of this new model.

惟以上所述者，僅為本新型的實施例而已，當不能以此限定本新型實施的範圍，凡是依本新型申請專利範圍及專利說明書內容所作的簡單的等效變化與修飾，皆仍屬本新型專利涵蓋的範圍內。However, the above are only examples of the present invention, which should not limit the scope of implementation of the present invention.
