Are you facing a black screen on your LCD display? This problem can be frustrating, and it can be challenging to identify the root cause and resolve it. In this article, we will discuss some common reasons for this problem and share some tips on how to fix it.

Ordinary LCD screens use CCFL light sources, that is, cold-cathode fluorescent lamps (similar to the scanning lamps in the copy), with one on each side of the screen and a backlight on the back of the display, which is composed of fluorescent substances. The light sources on both sides can be evenly distributed on the back of the entire screen, so that the entire screen can be evenly illuminated. However, due to technical limitations, the brightness of such a display is not completely uniform, but it is difficult to find it. At the same time, the lamp also has a certain lifespan, and it will turn yellow after a long time.

How to choose between amorphous silicon (a-Si) and low temperature polysilicon (LTPS) for project development with display
