Method for manufacturing glass light guide plate

Abstract

The invention provides a method for manufacturing a glass light guide plate. The method includes the following steps: preparing a glass substrate with a preset size, preferably an ultra clear glass in order to increase the properties of the light guide plates, cleaning and edging the ultra clear glass, one side of the glass substrate serving as a lattice point side, coating a protection film to the lattice point side; using a laser engraving machine to print dots of a predetermined lattice point pattern on the lattice point side, adjusting the laser intensity to the maximum level upon printing dots so that the glass substrate does not generate fine cracks; performing printing or coating on the lattice point side or spraying a printing ink to the lattice point side and curing the printing ink which can be selected from an UV curing printing ink or a thermal curing printing ink; and unveiling the protection film to obtain the glass light guide plate. The method herein uses a laser dotting method to form light guide points, uses the protection film, and synchronously perforates in the process of the laser dotting, obviates the need for silk screen printing in coating the printing ink and can perform direct printing, unveils the protection film after performing curing and can form recessed light guide lattice points which are coated with light guide printing ink. The method herein increases production efficiency and light guide properties.

Description

technical field [0001] The invention relates to the technical field of light guide plates, and specifically discloses a production method of a glass light guide plate. Background technique [0002] In the production of glass light guide plates, silk screen printing is generally used to form light guide points. In the production of organic light guide plates, laser dots are generally used to form light guide points. On the other hand, the light guide efficiency of the sunken light guide point formed on the glass plate is not good, so how to improve the light guide efficiency and solve the small cracks around the light guide point while applying laser dot processing is an existing problem. Weaknesses in technology. Contents of the invention [0003] Based on this, it is necessary to address the existing technical problems and provide a method for producing a glass light guide plate, which uses laser dots to form dots, and uses ink to fill the formed fine cracks, and at the ...
