Abstract

The invention relates to a diffusion sheet for a backlight module. The diffusion sheet comprises a base material layer and a diffusion layer, wherein the base material layer is made of a light-transmitting material; and the diffusion layer is laminated on the upper part of the base material layer and comprises an adhesive, nanoparticles and microparticles. Through the diffusion sheet with the structure, the rigidity of the diffusion layer can be improved so as to avoid the distortion and curling phenomena of the diffusion layer. In addition, the diffusion sheet has excellent diffusion effect according to the nanoparticle content of the diffusion layer, so that the defects of a light guide plate and an optical sheet can be effectively concealed or overcome and the luminance loss can be avoided.

Description

technical field

[0001] The invention relates to the field of liquid crystal displays, in particular to a diffusion sheet used in a backlight module. Background technique

[0002] In general, in order to improve the back surface of liquid crystal display devices (Liquid Crystal Display, LCD) including not only electronic light-emitting panels, notebook computer monitors, word processors, desktop computer monitors, TVs, video cameras, but also automotive and aircraft displays, etc. To illuminate the brightness of flat panel displays, backlight modules of various structures are used. The backlight module includes a light source, a light guide plate, and multiple optical sheets. The light from the light source passes through the light guide plate and multiple optical sheets and then exits to the display.

[0003] figure 1 It is a schematic diagram of an existing backlight module. Such as figure 1 As shown, the backlight module includes: a light source 4; a light guide plate 5...
