Problems solved by technology
However, injection molds and physical impact molds are both machine-processed. The disadvantages are: 1) the dots must not be less than 0.03mm; 2) high injection molding temperature and mold flow may easily cause local yellowing of the light guide plate, resulting in end-use 3) Physical collision points can easily cause damage to the base material of the light guide plate and generate debris. If the debris is not cleaned cleanly, it will cause scratches on the light guide plate and the backlight film, resulting in bright lines and bright spots when the terminal is used. 4) high manufacturing cost

The invention discloses a manufacturing method of light guide plate lattice points, and belongs to the technical field of light guide plates. The manufacturing method of the light guide plate lattice points comprises the following steps that S1, transparent UV glue is smeared on the first end face of a light guide plate base material; s2, the light guide plate base material is placed on a light guide plate dot transfer printing mold, and the transparent UV glue is located between the light guide plate base material and the light guide plate dot transfer printing mold; s3, rolling the second end face of the light guide plate base material by adopting rolling equipment; and S4, irradiating the light guide plate base material by adopting a UV irradiation furnace. The transparent UV glue is uniformly distributed, the UV irradiation furnace is used for irradiation after rolling is completed, the transparent UV glue is cured on the light guide plate base material, needed light guide plate net points are formed, timeliness is good, high temperature and mechanical stress do not exist, the surface of the light guide plate cannot be scratched, and poor display of a terminal is avoided.
Description
technical field [0001] The invention relates to the technical field of light guide plates, in particular to a method for manufacturing dots of light guide plates. Background technique [0002] At this stage, the manufacturing technology of light guide plate dots is basically high-temperature injection molding or physical impact forming. However, injection molds and physical impact molds are both machine-processed. The disadvantages are: 1) the dots must not be less than 0.03mm; 2) high injection molding temperature and mold flow may easily cause local yellowing of the light guide plate, resulting in end-use 3) Physical collision points can easily cause damage to the base material of the light guide plate and generate debris. If the debris is not cleaned cleanly, it will cause scratches on the light guide plate and the backlight film, resulting in bright lines and bright spots when the terminal is used. 4) The manufacturing cost is high. [0003] Therefore, there is an urge...
