How to clean the TFT LCD screen?

Sep 07, 2022

After using the TFT LCD screen for a period of time, you will find that a layer of dust is often adsorbed on the screen (it is more obvious when the LCD is turned off), and sometimes various water stains are accidentally stuck on, which will definitely greatly affect the visual effect. How to clean it?

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

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

No special solution or cloth is needed to clean the TFT LCD screen. Experience tells us that clean water + soft lint-free cloth or pure cotton lint-free cloth is the best TFT LCD screen cleaning tool (a paper towel that does not drop off). When cleaning, you can use a cotton lint-free cloth dipped in clean water and then wring it dry slightly, and then gently wipe the dust on the display with a slightly damp soft lint-free cloth (do not squeeze the display forcefully). It is recommended to wipe from the display Wipe one side to the other side until everything is wiped clean, don't wave it randomly.

Tips: Do not wipe with hard cloth or hard paper. At the same time, do not use cleaning fluids containing alcohol or acetone or cleaning agents containing chemical components, and do not spray the liquid directly onto the screen to prevent the liquid from penetrating into the protective film.

After cleaning the LCD screen with a damp, soft damp cloth, you can clean it again with a damp cloth that has been twisted dry. Finally, let the water vapor on the LCD screen dry naturally in a ventilated place.

Other maintenance points

Avoid vibration. LCD screens are very fragile, so strong shocks and vibrations should be avoided. Don't put pressure on the LCD screen or bump or squeeze the back cover of the LCD screen.

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, be careful with wallpapers and screensavers when using LCDs. The pictures of most wallpapers and screensavers are colorful, with a strong contrast between light and dark changes. Long-term use will distort the color of the LCD, which will affect the life of the LCD display. Therefore, it is best to use a monochrome screen and cancel the screen saver when using LCD.

Anti-electromagnetic interference. Whether it is a CRT or a TFT liquid crystal display, stay away from objects with strong magnetic fields. The surrounding strong magnetic fields will generate extra voltage inside the display, which affects 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 dot matrix LCD display.

Pay attention to humidity. Do not allow any moisture to enter the LCD. If the indoor humidity is too high, condensation may occur inside the LCD, which may cause leakage and short-circuit of the LCD, and even burn the display screen in severe cases. For some southern areas with high humidity, the LCD can be placed in a warm and dry place, or the back of the LCD screen can be baked with a low-power desk lamp on a regular basis to allow the moisture in it to evaporate.
