Mar 30, 2022
I don't know how the result of the backlight source is not clear. Then let me tell you, first of all, the backlight source is composed of light guide plate, film, shading edge paper and other materials. Every material is extremely important and indispensable. If the quality of one party is affected, the entire backlight source will be bad. Today we will introduce the light guide plate in the backlight and see what its characteristics are.
1. The raw material light guide plate of the backlight is made of acrylic, which is not very hard, so be careful when picking and placing, do not tear off the protective film in advance, otherwise it will be easily scratched when stacking, pay attention to reduce drag when picking up, Thereby reducing the possibility of scratches.
2. The light guide plate will also undergo thermal expansion and contraction at different temperatures, so the place where the light guide plate is stored should ensure that the temperature is appropriate, preferably around 25 °C, and the installation should also avoid contact with high temperatures, otherwise it will cause the board If it becomes longer and the thickness becomes thinner, or the plate becomes shorter and the thickness becomes thicker, it will not meet the requirements of the backlight product, resulting in scrap.
3. Many backlight sources will find some dirt and black spots during detection. In addition to the problem of the diaphragm, many of them are dirty and black spots on the light guide plate itself. Therefore, when cutting the light guide plate and making it, The environment should be kept as clean as possible. It is best to install it in a clean room. At the same time, the staff should wear masks and gloves to avoid dark spots and shadows caused by fingerprints and hand sweat, resulting in poor backlight products.
4. After the light guide plate is cut, once the film on the surface is torn off, it should be assembled as soon as possible, otherwise it will be easily contaminated with dust, resulting in black spots, which will affect the quality of the backlight.
