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.

LCD screen itself has problems. If it is indeed the screen itself that is at fault after testing with relevant instruments, in addition to replacing a new LCD screen, the device-related software should be debugged and optimized so that the screen can work with the motherboard's CPU. The best way is to increase the OSC frequency of the IC and see how the LCD screen flickers. Of course, if the TFT LCD screen has separate row and column drivers, you can also adjust it by setting the driver chip.

First, it should be clear that the main type of radiation produced by LCD monitors is low-frequency electromagnetic radiation, and its radiation level is far below international safety standards. Compared with the old cathode ray tube (CRT) monitors, LCDs have much less radiation. Therefore, the impact of LCD devices on the human body is very limited. However, there are ways to reduce the impact of this radiation. In this article, we will explore some effective ways to reduce LCD screen radiation.
