For the liquid crystal display, the light throughput is controlled by the design of the backlight module and the deflection of the liquid crystal. Therefore, light exposure is difficult to avoid. However, this light leakage will cause poor contrast of the display, especially in the dark area.
In this regard, adjustment by the provision of a light diffusion film has been made. However, the effect of the light diffusion film is still not effective in suppressing light leakage, and when a plurality of light diffusion films are used, interference fringes (Moire) are likely to occur due to mutual interference of light diffusion light rays.

Detailed Description
In the drawings, the widths of some of the elements, regions, etc. are exaggerated for clarity. Like reference numerals refer to like elements throughout the specification. It will be understood that when an element such as it is referred to as being "on" or "connected to" another element, it can be directly on or connected to the other element or intervening elements may also be present. In contrast, when an element is referred to as being "directly on" or "directly connected to" another element, there are no intervening elements present.
It will be understood that, although the terms first, second, third, etc. may be used herein to describe various elements, components, regions, or sections, these elements, components, regions, and/or sections should not be limited by these terms. These terms are only used to distinguish one element, component, region, or section from another element, component, region, layer, or section. Thus, a "first element," "component," "region," or "portion" discussed below could be termed a second element, component, region, or portion without departing from the teachings herein.
Furthermore, relative terms, such as "lower" or "bottom" and "upper" or "top," may be used herein to describe one element's relationship to another element, as illustrated. It will be understood that relative terms are intended to encompass different orientations of the device in addition to the orientation depicted in the figures. For example, if the device in one of the figures is turned over, elements described as being on the "lower" side of other elements would then be oriented on "upper" sides of the other elements. Thus, the exemplary term "lower" can include both an orientation of "lower" and "upper," depending on the particular orientation of the figure. Similarly, if the device in one of the figures is turned over, elements described as "below" other elements would then be oriented "above" the other elements. Thus, the exemplary terms "below" or "beneath" can encompass both an orientation of above and below.
FIG. 1 is a schematic cross-sectional view of a light leakage preventing film assembly. As shown in FIG. 1, the light leakage preventing film assembly 1 comprises 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 contacting the light diffusion layer 10. The light L incident from the bottom of the light diffusion layer 10 is scattered around the light diffusion layer 10, and after the scattered light L enters the anti-glare and anti-reflection layer 20, a part of the light L is refracted or reflected by the rough surface of the second surface 203. Thus, the external haze of the anti-glare anti-reflection layer 20 is 50% to 85%, as measured from the outside of the anti-glare anti-reflection layer 20.
Referring to fig. 1 again, the anti-glare and anti-reflection layer 20 includes an anti-glare portion 21 and an anti-reflection portion 23, the anti-glare portion 21 is disposed on the light diffusion layer 10, a lower surface of the anti-glare portion 21 is a first surface 201 contacting the light diffusion layer 10, and another side of the anti-glare portion 21 opposite to the light diffusion layer 10 is an uneven surface 211 having a rugged topography. The anti-reflection part 23 is disposed on the uneven surface 211, and the anti-reflection part 23 is disposed along the uneven surface 211 in an undulated manner to form a second surface 203 having a rough surface.
Here, the thickness of the antireflection portion 23 is 50 to 140 nm. Thus, at this thickness, the antireflection portion 23 is substantially undulated along the uneven surface 211. However, this is only a preferred embodiment and is not limited thereto in practice. The anti-glare anti-reflection layer 20 can be adjusted to have a desired external haze by adjusting the relief of the uneven surface 211 or adjusting the material and thickness of the anti-reflection portion 23. In more detail, the external haze is preferably 55% to 80%.
More specifically, when the light scattered in the light diffusion layer 10 enters the anti-glare part 21, a portion of the light L is refracted or reflected by the uneven surface 211, and a portion of the light L enters the anti-reflection part 23 through the anti-glare part 21, and is refracted or reflected by the anti-reflection part 23, or is refracted or reflected when reaching the second surface 203 with a rough surface. Therefore, the light leakage phenomenon of the horizontal visual angle can be improved, and a better contrast effect can be provided when the liquid crystal display is used in a dark state of a display. In other words, dark portions appear closer to black.
Fig. 2 is a detailed cross-sectional view of the light diffusion layer 10 of fig. 1. As shown in fig. 2, the light diffusion layer 10 includes a first diffusion 11 and a second diffusion 13.

The first diffusion 11 includes a plurality of first microstructures 111, and the second diffusion 13 includes a plurality of second microstructures 131. The first microstructures 111 and the second microstructures 113 are arranged periodically, and the first microstructures 111 are assembled with each other corresponding to the second microstructures 131. Here, the first microstructure 111 is represented by a bump corresponding to the second microstructure 131, and the first microstructure 111 is clamped between two bumps of the second microstructure 131. This is for example only and not limiting in nature.
The refractive index of the second diffusion 13 is greater than or equal to the refractive index of the first diffusion 11, and the refractive indices of the first diffusion 11 and the second diffusion 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, and preferably, the refractive index is designed to be gradually increased from the light diffusion layer 10 to the anti-glare anti-reflection layer 20, in other words, the refractive index can be gradually increased from the first diffusion 11, the second diffusion 13, the anti-glare portion 21 to the anti-reflection portion 23, but this is merely an example and is not limited thereto.
Fig. 3 is a schematic cross-sectional view of a display. As shown in FIG. 3, display 100 comprises backlight module 3, panel assembly 4, and 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 two opposite sides of the display panel 50. The first polarizing film 41 is positioned 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 light leakage prevention film assembly 1 includes a light diffusion layer 10 and an anti-glare anti-reflection layer 20, the light diffusion layer 10 is disposed on the second polarizing film 43, and the anti-glare anti-reflection layer 20 is disposed 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 with respect to the second surface 203 contacting the light diffusion layer 10, and the light L passing through the second polarizing film 43 enters the light diffusion layer 10 and is scattered toward the periphery in the light diffusion layer 10. After the scattered light L enters the anti-glare anti-reflection layer 20, a part of the light is refracted or reflected by the rough surface of the second surface 203, and the external haze of the anti-glare anti-reflection layer 20 is 50% to 85%, as measured from the outside of the anti-glare anti-reflection layer 20.

Here, the scan view angle is selected to be-80 to 80 degrees. In FIGS. 4A to 4C, a test curve of a display to which the light leakage preventing film assembly of the first embodiment is attached is shown by a thin solid line in order from the bottom to the top of the figure; indicated by a thin dashed line is a test curve for a display to which the light leakage prevention film assembly of the second embodiment is attached; the test curve of the display to which the light leakage preventing film assembly of comparative example 1 was attached is shown by one dot chain line; the test curve of the display to which the light leakage preventing film assembly of comparative example 2 was attached is shown by a short chain line; the test curve of the display to which the light leakage preventing film assembly of comparative example 3 was attached is shown by a two-dot chain line; the thick dotted line represents the test curve of the display to which the light leakage preventing film assembly of comparative example 4 was attached; and a test curve shown in bold solid lines for a display to which the light leakage prevention film assembly is not attached.
Here, the light leakage preventing film assembly of the first embodiment is composed of a light diffusion layer and an anti-glare and anti-reflection layer with an external haze of 70%. The light leakage preventing film assembly of the second embodiment is composed of a light diffusion layer and an anti-glare and anti-reflection layer with an external haze of 55%. The light leakage preventing film assembly of comparative example 1 was composed of a light diffusion layer and an anti-glare anti-reflection layer having an external haze of 40%. The light leakage preventing film assembly of comparative example 2 was composed of two light diffusion layers. The light leakage preventing film assembly of comparative example 3 has only a light diffusion layer; the anti-glare film assembly of comparative example 4 only had an anti-glare anti-reflective layer with an external haze of 70%.
As shown in fig. 4A to 4C, it can be clearly understood that, during the light leakage test at the dark state viewing angle, the scanning viewing angle corresponds to the intensity of light leakage, so that the display attached with the light leakage prevention film assembly of the first embodiment is the lowest, the display attached with the light leakage prevention film assembly of the first embodiment is the second lowest, which indicates that the degree of light leakage is less, and the display not attached with the light leakage prevention film assembly is the highest, which indicates that the light leakage is more serious.
FIGS. 5A to 5C are comparison graphs of Gamma curve tests according to different embodiments. Fig. 5A is a comparison graph of gray scale values versus intensity regression values at a viewing angle Φ (PHI) of 0 degrees and a scanning viewing angle θ of 30 degrees. Fig. 5B is a comparison graph of gray scale values and intensity regression values at a viewing angle Φ (PHI) of 0 degree and a scanning viewing angle θ of 60 degrees. Fig. 5C is a comparison graph of gray scale values versus intensity regression values at a viewing angle Φ (PHI) of 0 degrees and a scanning viewing angle θ of 45 degrees. In fig. 5A to 5C, the broken line is an ideal value representing a positive viewing angle (Gamma 2.2); the solid line shows the gamma test curve of the display to which the light leakage prevention film assembly of the first embodiment (light diffusion film and anti-glare anti-reflection layer with an external haze of 70%) was attached; the short chain line is a gamma test curve of the display to which the light leakage prevention film assembly of comparative example 3 (only one light diffusion film is attached); and a chain line is a gamma test curve of the display to which the light leakage prevention film assembly is not attached.
As shown in fig. 5A to 5C, the deviation value of the gamma test curve from the ideal curve of the display to which the light leakage film assembly is not attached is large. The gamma test curve of the display to which the light diffusion film assembly of the first embodiment (light diffusion film and anti-glare anti-reflection layer having an external haze of 70%) was attached and the gamma test curve of the display to which the light diffusion film assembly of the second embodiment 3 (only one light diffusion film was attached) was attached both approached the ideal curve.
The experimental results of the other examples are shown in table 1 below. As such, the effect of the external haze of the light diffusion layer 10 and the anti-glare anti-reflection layer 20 on the related effects can be observed.
The anti-glare anti-reflection layer 20 with an external haze of 50% to 85% and the light diffusion layer 10 are combined to form the anti-light-leakage film assembly 1, so that a dark area is not formed at a large viewing angle in a bright state, and a light leakage phenomenon at a horizontal viewing angle is greatly improved in a dark state, and light interference ripples in a display area are not generated. Meanwhile, for the user, the anti-glare effect and the contrast effect of the display 100 can be improved, thereby providing a clearer visual experience.
