Abstract

The invention relates to a manufacturing method of a transparent glass light guide plate. The manufacturing method comprises the following steps of (1) selecting a transparent glass substrate and placing the transparent glass substrate on a platform for negative-pressure leveling; (2) manufacturing a screen plate, and placing the screen plate on the glass substrate for adjustment and fixation; (3)uniformly coating a screen plate with a prepared anti-corrosion glass solvent such that the anti-corrosion glass solvent permeates into an original glass sheet through through holes in the screen plate, and completing the curing of the glass substrate; (4) taking away the screen plate, etching the cured glass substrate through a corrosion solvent, enabling the corrosion solvent to be in contact with a surface of the glass without the corrosion-resistant glass solvent, and forming a plurality of concave net points after reaction; and (5) cleaning a residual solvent on the glass substrate to finish the manufacturing of the light guide plate. The manufacturing method disclosed by the invention is relatively low in cost, the probability of lattice points on the glass and micro cracks around the lattice points is little, and so the quality of the light guide plate is improved.

Description

Technical field [0001] The invention relates to the technical field of light guide plates, and in particular to a method for manufacturing a transparent glass light guide plate. Background technique [0002] Existing light guide plates are used in backlights to convert point light sources into surface light sources to provide brightness to the LCD screen, making the display screen brighter and the colors of the screen more vivid and saturated. At present, most light guide plates are made of plastic plates or glass light guide plates. When plastic plates are used, they have large expansion and contraction properties. When the size is too large, the support is poor. Back plates and diaphragms are used to provide support and increase brightness. Back plates and diaphragms None of them are transparent, and there are certain limitations in the application field. Since the glass light guide plate is used for transparent display, there is no backplane or diaphragm, and it is mainl...
