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.

The LCD screen itself does not emit light, and a backlight needs to be added to the back of the glass for normal display. This involves how to test the surface brightness and backlight uniformity of the LCD screen. The brightness of the LCD screen surface and backlight brightness are measured through BM -7 equipment test, the test is more accurate when the display is powered normally and displays a solid color picture.

Liquid crystal display is a kind of flat panel display. It is used for the screen display of TV and computer. The advantages of the display are low power consumption, small size and low radiation.

TFT-LCD liquid crystal displays or LCD monitors have become a popular choice for a wide range of applications. However, LCD monitors can be divided into two categories: industrial and consumer. While both types of monitors offer excellent display quality, their designs differ. Industrial LCD monitors are often deployed in places such as factories, outdoor kiosks, digital signage, military and naval applications, food processing, and hospitals. On the other hand, consumer monitors are usually used in office and home environments.
