Abstract

The invention relates to a method for making a large-size hot-pressed screen, which produces a large-sized hot-pressed screen on a laser screen dotting machine with a limited stroke by splicing dots, and is obtained through the manufacturing method. The large-size hot-pressed screen embossed out the taste of the large-sized light guide plate meets the requirements, the division marks on the light guide plate are not obvious, and the optical uniformity is good, so as to solve the problem that the existing laser screen dotting machine is limited by the stroke and cannot be directly produced There is a problem with large-sized heat-pressed screen plates.

Description

technical field [0001] The invention relates to the technical field of light guide plates, in particular to a method for making a large-size hot-pressed screen plate. Background technique [0002] With the continuous upgrading of consumer demand for high-end large-screen TVs, the high-end large-screen market demand is strong. At present, there are three main processes for large-size light guide plates used in the field of liquid crystal display. The first is the printing light guide plate process, the second is the laser light guide plate process, and the third is the hot-pressed light guide plate process. Light guide plate companies at home and abroad have invested heavily in research and development, and the second-generation light guide plate process (ie, laser light guide plate process) has been gradually replaced by the third-generation light guide plate process (ie, hot-pressed light guide plate process). [0003] When making large-size hot-pressed light guide plates,...
