How to Clean the TFT Module

After the TFT module is used for a period of time, dust is often absorbed on the TFT screen (it is more obvious from the side after the power is turned off), and various water stains are sometimes accidentally stained. These have a great influence on the visual effect.


As a professional TFT display supplier, we will share some useful knowledge of the TFT LCD display with you.


Ⅰ. The method of cleaning TFT LCD screen


1. First, turn off the power of the TFT LCD display, and remove the power cord plug and the display cable plug.


2. Move the TFT LCD screen to a place with good natural light so that you can see the location of the dust. This is more targeted, so as to achieve a better cleaning effect.


3. TFT module cleaning does not require any special solution or wipes. Experience tells us that clean water, soft lint-free cloth or pure cotton lint-free cloth are the best cleaning tools for TFT displays. When cleaning, you can use a cotton lint-free cloth dipped in clean water and wring it dry, and then gently wipe the dust on the display with a slightly damp soft lint-free cloth. When wiping, it is recommended to wipe from one side of the display to the other side, until it is completely wiped clean, do not wipe randomly.


4. After cleaning the TFT module with a damp and soft damp cloth, you can clean it again with a wrung out damp cloth. Finally, dry the moisture of the TFT LCD screen naturally in a ventilated place.


Ⅱ. Other maintenance points of TFT LCD screen


1. Avoid vibration


The TFT LCD screen is very fragile, so strong shocks and vibrations should be avoided. Do not apply pressure to the TFT LCD screen, and do not bump or squeeze the back cover of the TFT module.


2. Avoid using the screen for a long time


Long working hours are not good for LCD. If not in use, be sure to turn off the power to the display. Similarly, use wallpaper and screen protectors with caution when using TFT screens. Most wallpapers and screensavers have bright colors and strong light and dark changes. Long-term use will distort the color of the LCD screen and affect the service life of the LCD screen.


3. Prevent electromagnetic interference


Whether it is a CRT or a TFT display, keep it away from objects with strong magnetic fields. The surrounding strong magnetic field will generate extra voltage inside the display, thereby affecting 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 service life of the TFT screen.


4. Pay attention to humidity


Do not let any moisture enter the TFT module. If the indoor humidity is too high, frost may form inside the TFT module. This will cause the LCD screen to leak and short-circuit, and in severe cases, it will burn the display. For some areas with high air humidity, the LCD screen can be placed in a warm and dry place, or the back of the TFT module can be baked with a low-power desk lamp on a regular basis to evaporate water.
