Optical prism sheet for backlight module

Abstract

The invention relates to the field of liquid crystal displays, and provides an optical prism sheet for a backlight module. The optical prism sheet comprises a base material layer, a light condensing layer and an anti-scratching layer, wherein the base material layer is made of a light-transmitting material; the light condensing layer is formed on the upper side of the base material layer and comprises a plurality of structured graphs at predetermined intervals; and the anti-scratching layer is on the lower side of the base material layer and forms a thickness of 0.1 to 3mu m by using a nanoparticle-containing ultraviolet curing adhesive. The scratch resistance of the lower side of the prism sheet is improved and the rigidity, distortion resistance and bend resistance of the improved prism sheet for the backlight module are improved by coating the nanoparticle-containing curing adhesive on the lower side of the base material layer with the structured graphs.

Description

technical field [0001] The present invention relates to the field of liquid crystal displays, in particular to an optical prism sheet for a backlight module. Background technique [0002] Generally speaking, in order to improve the back surface of not only electronic light-emitting panels, notebook computer monitors, word processors, desktop computer monitors, televisions, video cameras, but also liquid crystal display devices (LCDs), including automobile and aircraft monitors, etc. The brightness of the flat panel display is illuminated by backlight modules with various structures. The backlight module includes a light source, a light guide plate and a plurality of optical sheets. The light from the light source passes through the light guide plate and the plurality of optical sheets and then exits the display. [0003] figure 1 It is a schematic diagram of the existing backlight module. like figure 1 As shown, the backlight module includes: a light source 4; a light gui...
