Abstract

The invention provides a light guide plate substrate and a manufacturing method thereof. The light guide plate substrate comprises a fixing layer and a technological layer obtained by using a mother substrate for conducting sedimentation and detachment through the sedimentation technique, wherein the mother substrate has the same surface features with a light guide plate, the technological layer comprises a technological face and a fixing face which are opposite, the technological face is used for processing the light guide plate, and the fixing face is used for fixing the technological face to the fixing layer. By means of the light guide plate substrate and the manufacturing method thereof, only the mother substrate having the same surface features as the light guide plate needs to be obtained through the technology of laser engraving or mechanical impact or the like; compared with the light guide plate with convex diffusion point patterns, the mother substrate with concave diffusion point patterns is low in design and processing difficulty, in other words, the mother substrate having the same surface features as the light guide plate is used for conducting the processing such as sedimentation processing to obtain the light guide plate substrate, and thus the design and processing difficulty of the light guide plate substrate is lowered.

Description

technical field [0001] The invention relates to the field of manufacturing light guide plates, in particular to a light guide plate substrate for processing a light guide plate and a manufacturing method thereof. Background technique [0002] As users have higher and higher requirements for terminal display performance, traditional light guide plate manufacturing processes, such as screen printing / injection molding, can no longer meet the requirements of display technology due to problems such as uneven thickness / yellowing of light guide plates; Therefore, the prior art provides thermoforming technology, which requires a light guide plate substrate. After the material of the light guide plate is heated and softened, the pattern on the light guide plate substrate is embossed on the light guide plate, and the pattern on the light guide plate substrate is consistent with The patterns on the light guide plate are complementary. If it is necessary to emboss the concave diffusion ...
