Dongchen is a light guide film manufacturer that provides light guide films. We have more than 10 years of experience in this industry and can meet all your requirements. We provide competitive prices and good services and accept customized processing.
Why choose our light guide film?
1. More uniform light guide area, no visible dots (granular) distribution! Dongchen has a proprietary light guide microstructure (patented technology) design method. The new microstructure is more conducive to the transparent design of the keypad and improves the light energy utilization rate of the keypad!
2. Our light guide film is made by a hot pressing process. The precise optical dots or micro prism structure on the mold are copied to the surface of the film such as PC. The optical microstructure can effectively refract the light that is totally reflected in the PC film and out of the PC. The surface of the film. It is more environmentally friendly than printing and has higher light guide efficiency.
3. Fast design and proofing ability: In the research and development and technology of light guide products, we can independently design ultra-thin light guide devices of different shapes and colors for customers according to different product requirements, and carry out optical simulation analysis and improvement of backlight structure. Using cutting-edge MEMS technology, for the mobile phone keypad light source; 4 LED lights, through the optical design method, make the key surface light and soft and can obtain high brightness. For other large keyboards, it supports the rapid design, proofing, and mass production of various large-size microstructure light guide devices.
4. Have the international leading level and independent precision mold manufacturing capabilities: have excellent LIGA process equipment and UV molding equipment (laser etching, precision mold molding, micro-optical lithography, nanoimprinting process, precision screen printing, UV nano-pressure Printing, precision punching and optical inspection, the largest format can reach 40".
