Methods of cleaning TFT LCD
After using TFT LCD for a period of time, you will find that there is a layer of dust adsorbed on the display screen (it is more obvious when you turn off the LCD, and sometimes you will accidentally stick various water stains, which will greatly affect the visual effect. How to clean it?
① First turn off the LCD power, and remove the power cord plug and the graphics card connector 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 better cleaning effect.
③ It doesn’t need any special solution or cloth to clean TFT LCD. Experience tells us that water + soft velvet free cloth or pure cotton velvet free cloth is the best cleaning tool for TFT LCD. When cleaning, you can use pure cotton non fluffy cloth dipped in water, and then slightly dry, and then gently wipe the dust on the display screen with a slightly wet soft non fluffy wet cloth (do not squeeze the display screen with force). When wiping, it is recommended to wipe from one side of the display screen to the other side until it is completely wiped clean, and do not wave casually.
Tips: do not wipe with hard cloth or paper. At the same time, do not use cleaning solution containing alcohol or acetone or cleaning agent containing chemical composition, and do not spray the liquid directly to the screen, so as to avoid the liquid penetrating into the protective film.
④ After cleaning the LCD screen with a wet soft wet cloth, use a dry wet cloth to clean it again. Finally, let the water and air on the LCD screen dry naturally in the ventilation place.
Other maintenance points
① Avoid vibration. LCD screen is very fragile, to avoid strong shock and vibration. Do not put pressure on the LCD screen or impact or squeeze on the back cover of the LCD screen.
② Avoid using the screen for a long time. Long term work is not a good thing for LCD. If you don’t use it, be sure to turn off the monitor. In the same way, use wallpaper and screen saver carefully when using LCD. Most of the wallpaper and screen saver programs are colorful, and the light intensity changes strongly. Long time use will cause LCD color distortion, which will affect the life of LCD display. Therefore, when using LCD, it is better to use monochrome screen and cancel screen saver.
③ Anti electromagnetic interference. Both CRT and TFT LCD should be far away from objects with strong magnetic field. The strong magnetic field around the display will generate extra voltage inside the display, which will affect the stability of the display voltage. Long time in a strong magnetic field, will also make the color distortion, thus affecting the LCD display effect and life.
④ Pay attention to the humidity. Do not let any moisture into the LCD. If the indoor humidity is too high, condensation may occur inside the LCD, resulting in leakage and short circuit of the LCD, and even burning the display. For some southern areas with high humidity, the LCD can be placed in a warm and dry place, or the back of the LCD can be baked regularly with a table lamp with low power, so as to let the water evaporate.
