Problems solved by technology

However, when applying this patented technology, an additional light source alignment design must be proposed; moreover, this design also has the problems of difficulty in manufacturing and difficulty in controlling manufacturing errors, resulting in poor light uniformity
[0009] Furthermore, when traditional LCDs display dynamic images, blurred afterimages are often found. As far as the designs of the above-mentioned patented technologies are concerned, most of them solve

Abstract

The invention is a backlight module comprising a transparent substrate partitioned into multi areas, a grating structure located at the incident face of each area, and astigmatism structure of optical face used for receiving the incident light. The transparent substrate can be used to make partition sequential scan so as the grating structure can shorten the light-mixing distance; said astigmatism structure can evenly scatter the light out of the light-guiding plate.

Description

technical field [0001] The invention relates to an optical technology, in particular to a light guide plate applied to a backlight module and a backlight module with the light guide plate. Background technique [0002] Due to the continuous improvement of technology in recent years, the new generation of digital products can not only come from the technologies of the three major fields of information, consumption and communication, but also have the characteristics of multimedia performance. In this feature, image processing technology has gradually become a development area that attracts consumers' attention along with the maturity of various component technologies and increasing application areas. Fueled by the sharp increase in demand for imaging applications, there are more and more digital products with various overall display functions, which relatively makes the demand for displays also increase significantly. Among them, the most eye-catching one is Liquid Crystal Di...
