AI Technical Summary

Problems solved by technology

The above two light guide plate designs do not require printing ink outlets, which solves the problems of difficult control of the printing process, high investment in equipment, and easy pollution
However, the preparation process of the light-guiding particle components added in these two light-guiding plate designs is complicated and difficult to control, and the research and development costs are high, and the use cost is also high
Although there are some light guide particles with simple and common components on the market, the effect that they can achieve on the light guide plate is not ideal

Abstract

The invention discloses an MS light guide plate with a single-side microstructure and a light emergent micro-prism structure. The MS light guide plate comprises a light transmitting plate which comprises a light emergent surface and a bottom surface. The light transmitting plate is made of MS material. A prism structure is arranged on the light emergent surface. The prism structure is provided with multiple bulges which are arranged in parallel with arc-shaped cross sections. A V-shaped groove is formed between the two adjacent bulges. The depth and the span of the V-shaped groove are respectively set in 7-95 microns and 75-350 microns according to different thicknesses of the light transmitting plate. Spherical bulge arrays are arranged on the bottom surface. The spherical bulge arrays comprise M rows and N columns. Spherical bulges are identical in size and uniformly distributed on the bottom surface. The spherical bulges of the two adjacent rows are arranged in a staggered way in a row direction. The center-to-center distance between the two adjacent spherical bulges is 0.465-0.520mm. Meanwhile, the basal diameter of each spherical bulge is 0.205-0.230mm, and bulge height is 0.155-0.175mm. The light guide plate is made of the MS material, and different microstructures are arranged on the light emergent surface and the bottom surface so that performance of the light guide plate can be substantially enhanced.

Description

technical field [0001] The invention relates to an optical film, in particular to an MS light guide plate with a single-sided microstructure and a light-emitting microprism structure. Background technique [0002] At present, liquid crystal display devices have been applied in many electronic products due to their prominent advantage of being thin, such as liquid crystal televisions, desktop display screens or notebook computers. [0003] Generally, a liquid crystal display device includes a liquid crystal display panel and a backlight module. The working principle of the liquid crystal display panel is to place liquid crystal molecules between two parallel glass substrates. There are many vertical and horizontal small wires between the two glass substrates. The direction of the liquid crystal molecules is controlled by electrifying or not, and the light of the backlight module Refracted out to produce a picture. Since the liquid crystal display panel itself does not emit ...
