Abstract

An anti-light leakage film assembly includes a light diffusion layer and an anti-glare anti-reflection (AGAR) layer. One side of the AGAR layer is in contact with the light diffusion layer, and the AGAR layer is a rough surface with respect to the other side contacting the light diffusion layer. The light beam entered from the bottom of the light diffusion layer is scattered. Then, the light beam scattered enters the AGAR layer, and part of the light is refracted or reflected by the rough surface. The outer haze of the anti-glare anti-reflection layer is 50% to 85% which is measured by the outside of the anti-glare anti-reflection layer. Thereby, the light leakage phenomenon of the horizontal viewing angle can be greatly improved without causing light interference ripple. At the same time, it can enhance the anti-glare effect of a display device, and provides a clear visual experience, and the display device has better contrast in the dark state.

防漏光膜總成及應用該防漏光膜總成的顯示器Anti-leakage film assembly and display using the anti-leakage film assembly

本發明涉及顯示領域，尤其是一種防漏光膜總成及應用該防漏光膜總成的顯示器。The invention relates to the field of display, in particular to a light leakage prevention film assembly and a display using the light leakage prevention film assembly.

對於液晶顯示器，由於是透過背光模組的設計，且以液晶的偏轉來控制光線的通過量。因此，難以避免地有光線露出的現象。然而，這種漏光現象，將造成顯示器的對比效果不佳，尤其是在暗態的區域。For the liquid crystal display, because it is designed through the backlight module, and the deflection of the liquid crystal is used to control the amount of light passing. Therefore, it is difficult to avoid the phenomenon of light exposure. However, this light leakage phenomenon will cause poor contrast of the display, especially in dark areas.

對於此，現在已有透過光擴散膜的設置來調整。但是光擴散膜的效果仍然無法有效抑制漏光，若以多層光擴散膜，則容易因為光擴散光線相互干涉，而產生了干涉波紋(Moire)。For this, the setting through the light diffusion film has now been adjusted. However, the effect of the light diffusion film still cannot effectively suppress light leakage. If a multi-layer light diffusion film is used, it is easy to generate interference moire due to the interference of light diffusion light rays.

有鑑於此，在此提供一種防漏光膜總成。防漏光膜總成包含光擴散層以及抗眩光抗反射層。抗眩光抗反射層設置於光擴散層上，且抗眩光抗反射層相對於接觸光擴散層的一側為粗糙表面。由光擴散層底部入射的光線，在光擴散層中朝向四周散射，散射的光線進入抗眩光抗反射層後，部分的光線經粗糙表面產生折射或反射，由抗眩光抗反射層的外部所量測，抗眩光抗反射層之外霧度為50%至85%。In view of this, a light leakage prevention film assembly is provided here.

在此，還提供一種顯示器。顯示器包含背光模組、面板總成、及防漏光膜總成。背光模組產生光線。面板總成包含第一偏光膜、顯示面板、以及第二偏光膜。第一偏光膜及第二偏光膜分別貼附於顯示面板的相對兩側。第一偏光膜位於背光模組上方，將背光模組產生的光線導向顯示面板，第二偏光膜將通過顯示面板的光線導向視角方向。防漏光膜總成包含光擴散層及抗眩光抗反射層，光擴散層設置於第二偏光膜上，抗眩光抗反射層設置於光擴散層上。抗眩光抗反射層的一側與光擴散層接觸，而抗眩光抗反射層相對於接觸光擴散層的另一側為一粗糙表面，通過第二偏光膜的光線射入光擴散層中，並在光擴散層中朝向四周散射。散射的光線進入抗眩光抗反射層後，部分的光線經粗糙表面產生折射或反射，由抗眩光抗反射層的外部所量測，抗眩光抗反射層之一外霧度為50%至85%。Here, a display is also provided.

圖1為防漏光膜總成的剖面示意圖。如圖1所示，防漏光膜總成1包含光擴散層10及抗眩光抗反射層20。抗眩光抗反射層20的第一表面201接觸光擴散層10，且抗眩光抗反射層20相對於接觸光擴散層10的第二表面203為粗糙表面。由光擴散層10底部入射的光線L，在光擴散層10中朝四周散射，且散射的光線L進入抗眩光抗反射層20後，部分的光線L經第二表面203的粗糙表面產生折射或反射。因而，由抗眩光抗反射層20的外部所量測，抗眩光抗反射層20之外霧度為50%至85%。FIG. 1 is a schematic cross-sectional view of the light leakage prevention film assembly. As shown in FIG. 1, the light leakage prevention film assembly 1 includes a light diffusion layer 10 and an anti-glare anti-reflection layer 20. The first surface 201 of the anti-glare anti-reflection layer 20 contacts the light diffusion layer 10, and the anti-glare anti-reflection layer 20 is a rough surface with respect to the second surface 203 that contacts the light diffusion layer 10. The light L incident from the bottom of the light diffusion layer 10 is scattered around in the light diffusion layer 10, and after the scattered light L enters the anti-glare anti-reflection layer 20, part of the light L is refracted by the rough surface of the second surface 203 or reflection. Therefore, as measured from the outside of the anti-glare anti-reflection layer 20, the haze outside the anti-glare anti-reflection layer 20 is 50% to 85%.

再次參閱圖1，抗眩光抗反射層20包含抗眩光部21及抗反射部23，抗眩光部21設置於光擴散層10上，抗眩光部21的下表面為與光擴散層10接觸的第一表面201，且抗眩光部21相對於光擴散層10的另一側為不平整表面211，具有凹凸起伏的地貌。抗反射部23設置於不平整表面211上，且抗反射部23的沿著不平整表面211起伏設置而形成具有粗糙表面的第二表面203。Referring again to FIG. 1, the anti-glare anti-reflection layer 20 includes an anti-glare portion 21 and an anti-reflection portion 23. The anti-glare portion 21 is provided on the light diffusion layer 10, and the lower surface of the anti-glare portion 21 is the first surface in contact with the light diffusion layer 10 A surface 201, and the other side of the anti-glare portion 21 with respect to the light diffusion layer 10 is an uneven surface 211, which has uneven topography. The anti-reflection portion 23 is provided on the uneven surface 211, and the anti-reflection portion 23 is undulated along the uneven surface 211 to form a second surface 203 having a rough surface.

在此，抗反射部23的的厚度為50至140nm。因而，在此厚度下，抗反射部23基本上沿著不平整表面211而起伏。然而，這僅為較佳的實施方式，實際上並不限於此。透過調整不平整表面211之凹凸起伏的地貌，或是調整抗反射部23的材料、厚度，均可以調整抗眩光抗反射層20為所需的外霧度。更詳細地，外霧度較佳地為55%至80%。Here, the thickness of the anti-reflection portion 23 is 50 to 140 nm. Thus, at this thickness, the anti-reflection portion 23 basically undulates along the uneven surface 211. However, this is only a preferred embodiment and is not actually limited to this. By adjusting the uneven topography of the uneven surface 211, or adjusting the material and thickness of the anti-reflection portion 23, the anti-glare anti-reflection layer 20 can be adjusted to a desired external haze. In more detail, the outer haze is preferably 55% to 80%.

更詳細地，在光擴散層10中散射的光線:進入抗眩光部21，部分的光線L經不平整表面211產生折射或反射，而部分的光線L會通過抗眩光部21進入抗反射部23，在抗反射部23產生折射或反射，或是到達具有粗糙表面的第二表面203時產生折射或反射。如此，能改善水平視角的漏光現象，並且用於顯示器的暗態時，能提供更佳的對比效果。換言之，暗處部分會更呈現更接近黑色。In more detail, light scattered in the light diffusion layer 10: entering the anti-glare portion 21, part of the light L is refracted or reflected through the uneven surface 211, and part of the light L will enter the anti-reflection portion 23 through the anti-glare portion 21 When the anti-reflection part 23 is refracted or reflected, or when it reaches the second surface 203 having a rough surface, it is refracted or reflected. In this way, the light leakage phenomenon of the horizontal viewing angle can be improved, and when used in the dark state of the display, a better contrast effect can be provided. In other words, the dark parts will appear closer to black.

圖2為圖1中光擴散層10的細部剖面示意圖。如圖2所示，光擴散層10包含第一擴散部11及第二擴散部13。第二擴散部13位於第一擴散部11與抗眩光抗反射層20之間。第一擴散部11包含複數個第一微結構111，第二擴散部13包含複數個第二微結構131。第一微結構111及第二微結構113呈周期性排列，且第一微結構111對應第二微結構131而相互組接。在此，第一微結構111對應第二微結構131是以凸塊來呈現，第一微結構111卡設於第二微結構131的兩凸塊之間。但此僅用以示例，實際上並不限於此。FIG. 2 is a detailed cross-sectional schematic diagram of the light diffusion layer 10 in FIG. 1. As shown in FIG. 2, the light diffusion layer 10 includes a first diffusion part 11 and a second diffusion part 13. The second diffusion portion 13 is located between the first diffusion portion 11 and the anti-glare anti-reflection layer 20. The first diffusion portion 11 includes a plurality of first microstructures 111, and the second diffusion portion 13 includes a plurality of second microstructures 131. The first microstructure 111 and the second microstructure 113 are periodically arranged, and the first microstructure 111 corresponds to the second microstructure 131 and is assembled with each other. Here, the first microstructure 111 corresponding to the second microstructure 131 is represented by bumps, and the first microstructure 111 is stuck between the two bumps of the second microstructure 131. However, this is only used as an example, and is not limited to this.

第二擴散部13的折射率大於或等於第一擴散部11的折射率，且第一擴散部11及第二擴散部13的折射率為1.4至1.6。此外，抗眩光抗反射層20的折射率為1.4至1.6，較佳地，折射率的設計由光擴散層10至抗眩光抗反射層20漸增，換言之，其折射率可以由第一擴散部11、第二擴散部13、抗眩光部21至抗反射部23逐漸地增加，但此僅為示例，實際上並不限於此。The refractive index of the second diffusion part 13 is greater than or equal to the refractive index of the first diffusion part 11, and the refractive indexes of the first diffusion part 11 and the second diffusion part 13 are 1.4 to 1.6. In addition, the refractive index of the anti-glare anti-reflection layer 20 is 1.4 to 1.6. Preferably, the design of the refractive index gradually increases from the light diffusion layer 10 to the anti-glare anti-reflection layer 20. In other words, the refractive index can be determined by the first diffusion 11. The second diffusion part 13, the anti-glare part 21 to the anti-reflection part 23 are gradually increased, but this is only an example, and is not actually limited to this.

圖3為顯示器的剖面示意圖。如圖3所示，顯示器100包含背光模組3、面板總成4、及防漏光膜總成1。背光模組3產生光線L。面板總成4包含第一偏光膜41、顯示面板50、以及第二偏光膜43。第一偏光膜41及第二偏光膜43分別貼附於顯示面板50的相對兩側。第一偏光膜41位於背光模組3上方，將背光模組3產生的光線導向顯示面板50。第二偏光膜43將通過顯示面板50的光線導向視角方向。防漏光膜總成1包含光擴散層10及抗眩光抗反射層20，光擴散層10設置於第二偏光膜43上，抗眩光抗反射層20設置於光擴散層10上。抗眩光抗反射層20的第一表面201接觸光擴散層10，且抗眩光抗反射層20相對於接觸光擴散層10的第二表面203為粗糙表面，通過第二偏光膜43的光線L射入光擴散層10中，並在光擴散層10中朝向四周散射。散射的光線L進入抗眩光抗反射層20後，部分的光線經第二表面203粗糙表面產生折射或反射，由抗眩光抗反射層20的外部所量測，抗眩光抗反射層20之外霧度為50%至85%。3 is a schematic cross-sectional view of a display. As shown in FIG. 3, the display 100 includes a backlight module 3, a panel assembly 4, and a light leakage prevention film assembly 1. The backlight module 3 generates light L. The panel assembly 4 includes a first polarizing film 41, a display panel 50, and a second polarizing film 43. The first polarizing film 41 and the second polarizing film 43 are respectively attached to opposite sides of the display panel 50. The first polarizing film 41 is located above the backlight module 3 and guides the light generated by the backlight module 3 to the display panel 50. The second polarizing film 43 guides the light passing through the display panel 50 to the viewing angle direction. The anti-light leakage film assembly 1 includes a light diffusion layer 10 and an anti-glare anti-reflection layer 20. The light diffusion layer 10 is provided on the second polarizing film 43, and the anti-glare anti-reflection layer 20 is provided on the light diffusion layer 10. The first surface 201 of the anti-glare anti-reflection layer 20 contacts the light diffusion layer 10, and the anti-glare anti-reflection layer 20 is a rough surface relative to the second surface 203 contacting the light diffusion layer 10, and the light L passing through the second polarizing film 43 is emitted It enters the light diffusion layer 10 and scatters around in the light diffusion layer 10. After the scattered light L enters the anti-glare anti-reflection layer 20, part of the light is refracted or reflected by the rough surface of the second surface 203, which is measured from the outside of the anti-glare anti-reflection layer 20. The degree is 50% to 85%.

Here, the selection of the scanning viewing angle is -80 degrees to 80 degrees.

如圖4A至圖4C所示，可以明顯的理解，在暗態視角漏光測試時，掃描視角對應漏光的強度，以貼附第一實施例之防漏光膜總成的顯示器最低、貼附第一實施例之防漏光膜總成的顯示器次低，表示漏光的程度較少，以未貼附防漏光膜總成的顯示器最高，表示漏光較為嚴重。As shown in FIGS. 4A to 4C, it can be clearly understood that in the dark state viewing angle light leakage test, the scanning viewing angle corresponds to the intensity of light leakage, and the display with the light leakage prevention film assembly of the first embodiment attached is the lowest and the first attached The display of the light leakage prevention film assembly of the embodiment is the second lowest, indicating that the degree of light leakage is less, and the display without the light leakage prevention film assembly is the highest, indicating that the light leakage is more serious.

圖5A至圖5C為不同實施方式迦瑪(Gamma)曲線測試的比對圖。圖5A為視角Φ(PHI)=0度、掃描視角θ=30度的灰階值-強度回歸值的比對圖。圖5B為視角Φ(PHI)=0度、掃描視角θ=60度的灰階值-強度回歸值的比對圖。圖5C為視角Φ(PHI)=0度、掃描視角θ=45度的灰階值-強度回歸值的比對圖。在圖5A至圖5C中，虛線是表示正視角(Gamma 2.2)的理想值；實線是表示貼附實施例一之防漏光膜總成(光擴散膜及外霧度為70%的抗眩光抗反射層)的顯示器之迦瑪測試曲線；短鏈線是貼附比較例3之防漏光膜總成(只貼附一層光擴散膜)的顯示器之迦瑪測試曲線；以及一點鏈線是指未貼附防漏光膜總成之顯示器的迦瑪測試曲線。5A to 5C are comparison diagrams of Gamma curve tests in different embodiments. FIG. 5A is a comparison diagram of gray scale value-intensity regression value of viewing angle Φ(PHI)=0 degrees and scanning viewing angle θ=30 degrees. FIG. 5B is a comparison diagram of the gray scale value-intensity regression value of the viewing angle Φ(PHI)=0 degrees and the scanning viewing angle θ=60 degrees. FIG. 5C is a comparison diagram of gray-scale value-intensity regression value of viewing angle Φ(PHI)=0 degrees and scanning viewing angle θ=45 degrees. In FIGS. 5A to 5C, the dotted line represents the ideal value of the positive viewing angle (Gamma 2.2); the solid line represents the anti-glare film assembly (light diffusion film and external haze of 70%) attached to the first embodiment Gamma test curve of the display with anti-reflection layer; the short chain line is the Gamma test curve of the display with the light leakage prevention film assembly of Comparative Example 3 (only one layer of light diffusion film attached); and the one-point chain line means Gamma test curve of the display without the light leakage prevention film assembly attached.

如圖5A至圖5C所示，未貼附漏光膜總成之顯示器的迦瑪測試曲線與理想曲線的偏離值較大。貼附實施例一之防漏光膜總成(光擴散膜及外霧度為70%的抗眩光抗反射層)的顯示器之迦瑪測試曲線、以及貼附比較例3之防漏光膜總成(只貼附一層光擴散膜)的顯示器之迦瑪測試曲線，都較趨近於理想曲線。As shown in FIGS. 5A to 5C, the deviation of the gamma curve of the display without the light leakage film assembly from the ideal curve is large. The gamma test curve of the display attached with the light leakage prevention film assembly of Example 1 (light diffusion film and antiglare antireflection layer with an external haze of 70%), and the light leakage prevention film assembly of Comparative Example 3 ( The Gamma test curve of the monitor with only one layer of light diffusion film attached to it is closer to the ideal curve.

另外，其他前述這些示例的實驗結果，如下表1所示。如此，可以觀看出光擴散層10及抗眩光抗反射層20的外霧度對於相關效果的影響。表1

In addition, the experimental results of the other aforementioned examples are shown in Table 1 below. In this way, the influence of the external haze of the light diffusion layer 10 and the anti-glare anti-reflection layer 20 on the related effects can be seen. Table 1

在此，以具有外霧度50%至85%的抗眩光抗反射層20與光擴散層10組合成防漏光膜總成1，在亮態時在大視角不會呈現暗區，而暗態時，能大幅改善水平視角的漏光現象，也不會產生顯示區域的光干涉波紋。同時，對於使用者，能提升顯示器100的抗眩光效果及對比效果，而提供更清晰的視覺感受。Here, the anti-glare anti-reflective layer 20 with an external haze of 50% to 85% and the light diffusion layer 10 are combined to form a light leak-proof film assembly 1, which does not show dark areas at a large viewing angle in the bright state, while the dark state At this time, the light leakage phenomenon at the horizontal viewing angle can be greatly improved, and the light interference ripple in the display area is not generated. At the same time, for the user, the anti-glare effect and the contrast effect of the display 100 can be improved while providing a clearer visual experience.
