The TFT liquid crystal display screen is a thin film field effect transistor, which means that each liquid crystal pixel point on the liquid crystal display is driven by a thin film transistor integrated behind it. Thus, high-speed, high-brightness, high-contrast display screen information can be achieved, and TFT belongs to an active matrix liquid crystal display. TFT LCD display is more delicate than CRT display. How to maintain it?

1.How to clean TFT LCD

After using the TFT liquid crystal display for a period of time, it will be found that a layer of dust is often adsorbed on the display (it is more obvious when the LCD is turned off), and sometimes various water stains are accidentally stuck, which greatly affects the visual effect and how to clean it. How about it?

① Turn off the LCD power first, and remove the power cord plug and the graphics card cable plug.

② Move the LCD to a place with better natural light so that you can see where the dust is, which is more conducive to targeted, so as to achieve a better cleaning effect.

③ No special solution or wiping cloth is needed to clean the TFT LCD screen. Water + soft lint-free cloth or cotton lint-free cloth is a good tool for cleaning the TFT LCD screen (it is also possible to remove paper towels). When cleaning, you can use a cotton lint-free cloth dipped in water and wring it a little, and then gently wipe the dust on the display with a slightly damp and soft lint-free wet cloth (do not squeeze the display forcefully). Wipe from one side to the other until everything is clean.

Tip: Do not wipe with a hard cloth or paper. At the same time, never use a cleaning solution containing alcohol or acetone or a cleaning agent containing chemical components, and never spray the liquid directly onto the screen to prevent the liquid from penetrating into the protective film.

④ After cleaning the LCD screen with a damp, soft, damp cloth, use a damp cloth that has been wrung dry to clean it again. Then let the air and water on the LCD screen dry naturally in a ventilated place.

2. Other maintenance points

① Avoid vibration. The LCD's LCD screen is very fragile. Avoid strong shocks and vibrations. Do not put pressure on the LCD screen or bump or squeeze it on the LCD screen back cover.

② Avoid using the screen for a long time. Long-term work is not a good thing for LCD. If you are not using it, you must turn off the power of the display. For the same reason, use wallpapers and screen savers with caution when using the LCD. Most wallpapers and screen saver programs have bright colors, and the contrast between light and dark changes is strong. Long-term use will distort the LCD color and affect the life of the LCD display. Therefore, it is better to use a monochrome screen and cancel the screen saver when using the LCD.

③ Prevent electromagnetic interference. Whether it is a CRT or TFT LCD display, keep it away from objects with strong magnetic fields. The strong magnetic field around it will cause extra voltage inside the display, which will affect the stability of the display voltage. Being in a strong magnetic field for a long time will also cause color distortion, which will affect the display effect and life of the LCD.

④ Pay attention to humidity. Do not allow any moisture to enter the LCD. If the humidity in the room is too high, condensation may occur inside the LCD, resulting in leakage and short circuit of the LCD, and serious damage to the display. For some southern regions with high humidity, the LCD can be placed in a warmer and dry place, or the back of the LCD screen can be baked regularly with a low-power desk lamp to allow the water in it to evaporate.
