What Is The Injection Principle Of LED Light Guide Plate?
Jan 20, 2022
The LED light guide plate is based on optical grade acrylic, using LCD display and backlight module technology, through the full high light transmittance of the light guide point, and the computer design of the light guide point makes the light of the LED light guide plate converted into a surface light source. The light state is manufactured and formed, so what is the injection principle of the LED light guide plate?
The injection molding of the LED light guide plate is the best way to control the deformation. The LED light guide plate is now mainly a wedge-shaped plate, which is thick at the light entrance and thin at the light exit. The common warping is positive warping, reverse warping, and S-shaped warping.
For the upturn and inversion of the LED light guide plate, it is often adjusted by adjusting the mold temperature, that is, adjusting the temperature of the male and female molds to adjust. When adjusting the temperature of the male and female molds, you should pay attention to it. Usually, it is not recommended to adjust the biting surface. The reason is that the temperature of the bite surface has a great influence on the optical characteristics. If the temperature of the mirror surface is still warped, the mold temperature of the bite surface can also be adjusted, but pay attention to the optical characteristics. In addition to the mold temperature, it can also be adjusted by To modify the forming conditions, you can test the holding pressure, the body speed, and the compression.
For the S-shaped warping of the LED light guide plate, it is mainly caused by overfilling or shrinking. It is necessary to consider the shooting distance, firing rate, pressure holding time, and compression conditions.
