When all human beings enter the era of intelligent technology, the capacitive and resistive full-touch LCD screen makes our life and work more convenient. However, when the screen also fails, the next step is to repair the fault. The editor summed up the knowledge about damage, repair and maintenance of touch LCD screens, which can help everyone learn better care of touch LCD screens, and it will not delay normal work presentations and life needs.

Cause of Damage

1. Reasons for static electricity: Usually touchable LCD screens are capacitive screens, and the positioning method of the touch screen is carried out through an electric field, so static electricity and discharge will be generated, and the LCD touch screen will produce a "drift" screen effect.

2. Physical reasons: The so-called physical damage is that hard objects directly affect the LCD screen, such as impact. This is the cause of direct damage to the touch LCD screen, and even the direct scrapping of the touch LCD screen.

3. Other reasons: Other conductive substances can also cause damage to the touch LCD screen, water stains, water vapor and sweat stains can damage the touch screen circuit, thus causing the screen to not work properly.

Screen Maintenance Procedures

1. It is necessary to professionally maintain the touch LCD screen, first determine the cause of the accident, and then find out from which aspect the touch LCD screen is damaged, so as to accurately determine where the LCD screen needs to be repaired, and then repair or replace internal parts.

2. The cause of damage to the LCD screen caused by circuit failure can be repaired to the external connection line of the LCD screen. The LCD screen is damaged by the penetration of liquid and gas. The LCD screen needs to be cleaned and air-dried, and some burnt parts should be replaced if necessary.

Maintenance

1. Film protection

The protective effect of the tempered glass film developed for the LCD screen is the best. Strong external shocks can damage the tempered glass, but the touch screen LCD will still work just as well as before. In addition, the film prevents dust from entering the screen, there by avoiding damage to the touch sensitivity of the LCD screen.

2. Waterproof protection

Water will bring great harm to the screen, which will be fatal, and the consequences of turning on water and electricity at the same time are unimaginable. Remember to keep your hands dry and avoid touching the screen directly.
