The maintenance points of TFT display screen mainly include the following aspects:

1、 Cleaning and maintenance

Regular cleaning: The surface of TFT display screens is prone to absorbing dust, fingerprints, and dirt, and regular cleaning is the key to maintaining their appearance and performance. When cleaning, a clean microfiber cloth or soft cotton cloth should be used to gently wipe, avoiding the use of hard cloths or cleaning agents containing alcohol, acetone, and other chemical components to avoid scratching the screen or damaging the screen coating.

Cleaning method: Before cleaning, turn off the power of the display screen and remove the power cord plug and graphics card connection cable plug. You can use clean water (or professional cleaning agents, if conditions permit) and a soft cloth for wiping, but make sure the cloth does not drip and gently wring it out to prevent liquid from seeping into the inside of the screen. When wiping, wipe from one side of the display screen to the other, avoiding shaking or squeezing the screen forcefully.

2、 Usage environment

Avoid direct sunlight: Prolonged exposure to sunlight may cause a decrease in brightness, color distortion, and even pixel damage to TFT displays. Therefore, it is advisable to avoid placing the display screen in direct sunlight or using sunshades or other obstructions.

Appropriate temperature and humidity: Both high temperature and humid environments may cause damage to TFT displays. High temperature can accelerate screen aging, while high humidity may cause internal circuit short circuits. Therefore, the display screen should be kept working in a suitable temperature and humidity environment, avoiding use under extreme conditions.

3、 Usage habits

Avoid prolonged continuous use: Prolonged continuous use can cause the screen temperature to rise, thereby affecting its lifespan. Therefore, when using TFT display screens, appropriate rest time should be arranged to allow the screen to cool down.

Avoid excessive pressure and vibration: TFT displays are relatively fragile, and excessive pressure or vibration should be avoided. When moving or installing the display screen, handle it gently to avoid collision or compression.

Avoid static electricity and electromagnetic interference: Static electricity and electromagnetic interference may interfere with the normal operation of TFT displays. Therefore, it is advisable to avoid placing objects that generate static electricity near the display screen as much as possible, and to place them away from strong magnetic fields.

4、 Other precautions

Regularly check and update drivers: Drivers are crucial for the proper functioning of TFT displays. Regularly checking and updating drivers can solve some display issues such as flickering, distortion, etc.

Pay attention to the stability of the connecting wire: Loose or poor contact of the connecting wire may cause signal interference or noise. Therefore, it is necessary to regularly check whether the connecting wires are well connected to ensure that the plug is firmly inserted into the interface.

Avoid displaying static images for extended periods of time: Prolonged display of static images may result in "image retention" or "burn-in" issues. Therefore, when displaying static images, the screen brightness and contrast should be adjusted appropriately, and the display content should be replaced regularly.

In summary, the maintenance points of TFT display screens include regular cleaning and maintenance, paying attention to the usage environment, developing good usage habits, and paying attention to other precautions. By proper maintenance and upkeep, the lifespan of TFT displays can be extended and their good performance can be maintained.
