The main material of light guide plate is PMMA plate, its chemical name is methyl methacrylate, its specific gravity is 1190kg per cubic meter. Transparent acrylic sheet is widely used because of its high light transmittance and strong impact capacity. At present, the quality of acrylic plate is different due to different processes of different manufacturers. In particular, although the recycled plate is cheap, it is easy to yellowing, and the light transmittance is also poor. The acrylic plate for light guide plate production should choose the transparent plate which is not easy to yellowing, and the light transmittance is more than 92% - 93%.
Methods and steps:
1. After special scientific processing, as long as the light-emitting body is installed on the side of the transparent acrylic plate (depending on the area of the light guide plate, ordinary fluorescent tubes, CCFL cold cathode lamps, light-emitting diodes and other light sources can be selected, generally installed on both sides of the length, and only one side can be installed when the width is relatively small), the whole plane of the acrylic plate will emit bright, uniform and soft light after power on, It is called light guide plate.
2. There are two ways to make light guide plate: screen printing and non printing. The screen printing light guide plate has the advantages of low investment, no equipment investment, complete manual operation, low cost, high production efficiency and easy to master technology; Nonprinting light guide plate has the advantages of large investment, professional equipment, high production cost, low production efficiency, and difficult technology for ordinary people to master (nonprinting light guide plate can be divided into several categories in terms of production methods. For details, please refer to the comprehensive information column (comparison of light guide plates with different production methods). The author focuses on the promotion of screen printing light guide plate manufacturing method.
3. Special reflective film, astigmatism film, brightening film and reflective aluminum film for backlight made in Japan and Taiwan
