Example Embodiment

[0025] The present invention will be described in detail below with reference to the embodiments shown in the drawings. However, these embodiments do not limit the present invention, and the structural, method, or functional changes made by those of ordinary skill in the art based on these embodiments are all included in the protection scope of the present invention.

[0026] Participate figure 1 , figure 2 versus image 3 As shown, the diffuser 100 provided by the present invention is a multi-layer diffuser. Compared with the existing single-layer diffuser, it can diffuse light in multiple levels, improve the diffusion effect, and improve the diffusion of the light-emitting surface of the single-layer diffuser. The microstructure can effectively improve the viewing angle of the diffuser plate and comprehensively improve the light quality.

[0027] In the present invention, the aforementioned diffuser plate 100 includes a diffuser single layer 10, and the diffuser single layer 10...

Abstract

The invention provides a diffuser plate which comprises at least two single diffusion layers, and each single diffusion layer comprises a diffusion particle layer and a light refracting layer arranged above the diffusion particle layer, and the light refracting layer comprises at least one protruding microstructure; the direction of the light penetrating the diffuser plate is defined as the first direction, and the diffusion particle layer comprises an initial single diffusion layer and a wide angle single diffusion layer distributed in the first direction; and the wide angle single diffusion layer comprises a wide angle protruding microstructure with a semicircular section. Compared with the prior art, the diffuser plate provided by the invention achieves multi-layer diffusion of the in-light by increasing the number of the single diffusion layer, the diffusion effect of the in-light is improved; and as the microstructure shape of the wide angle single diffusion layer of the out-light is changed, the positive visual angle of the diffuser plate is improved, and the out-light effect of the diffuser plate is further improved as well.

Description

technical field [0001] The invention relates to the field of optical materials, in particular to a diffuser plate. Background technique [0002] In the current field of display equipment and lighting equipment, in order to obtain uniform and soft display effects and lighting effects, light diffusion materials and technologies have been widely used, among which diffusion plates are widely used as a commonly used diffusion device at present. [0003] In the display device, take the liquid crystal display as an example, since the liquid crystal itself does not emit light, it needs to provide a backlight module to enable the liquid crystal display to display images normally, and the backlight module is required to provide a high-brightness and uniformly distributed light source, so it is often used in the backlight module. A diffuser plate is added in front of the light source of the group to allow the light to enter the liquid crystal panel evenly, thereby improving the display...
