Abstract

A manufacture method for a light conducting plate includes the following steps: providing a material base plate, and a die base plate with a recess pattern composed of a side and a bottom, utilizing said die base plate to ho-press said material one in which, the bottom of the recessed pattern has a gap with the material plate, which forms a related convex pattern by the pressure of the die plate and the surface tension of the material base plate and removing said die base plate from a light conducting plate. This invention applies a non-contact hot-press method to produce the light conducting plates to prolong the lift time of die sets.

Description

【Technical field】 [0001] The invention relates to a method for manufacturing a light guide plate, in particular to a method for manufacturing a light guide plate for a liquid crystal display. 【Background technique】 [0002] In recent years, with the colorization and enlargement of liquid crystal displays, their application fields are more extensive, such as notebook computers, various desktop computers, and LCD TVs. Because the liquid crystal display is a passive component, it cannot emit light by itself, so it is necessary to use a light source system as the light source of the liquid crystal display, such as the backlight module (BacklightModule), wherein the light guide plate is an important component in the backlight module to guide The transmission direction of the light beam emitted from the light source, converting the line light source or point light source into a surface light source to emit. [0003] In order to improve the uniformity of light output, dots are gen...
