Abstract

A light guide plate and manufacturing method thereof, the light guide plate manufacturing method mainly comprising: forming a light guide plate body (1); then forming a plurality of light scattering units (2) within the light guide plate body (1), the light scattering units (2) being arranged according to a specific rule. The light scattering units (2) can reduce light guide plate color differences, avoid the generation of a dead pixel, and improve light emission efficiency.

Description

【Technical field】 [0001] The invention relates to a light guide plate, in particular to a light guide plate capable of reducing chromatic aberration and improving light emission efficiency and a manufacturing method thereof. 【Background technique】 [0002] Since the liquid crystal panel of the liquid crystal display does not have the function of self-illumination, the liquid crystal display needs to be further equipped with a backlight module to supply sufficient and evenly distributed surface light sources for the liquid crystal panel. Generally speaking, backlight modules can be mainly divided into two types: direct-type and side-type, and the light guide plate is a key component for the side-type backlight module to provide a uniform surface light source. The light guide plate uses the principle of total reflection to transmit the light entering from the side of the light guide plate to the far end of the light guide plate. [0003] In order to allow light to be evenly e...
