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 the touch LCD screen, which can help everyone learn better care of the touch LCD screen, and it will not delay the normal work presentation 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. The touch LCD screen needs to be professionally maintained. First determine the cause of the accident and 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 the internal parts.
2. The cause of damage to the LCD screen caused by a circuit failure can repair the external connection circuit of the LCD screen. If the LCD screen is damaged, the capacitor LCD screen or internal structural parts can be replaced according to the situation. The LCD screen is damaged by liquid and gas penetration, the LCD screen needs to be cleaned and air-dried, and some burned-out 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 touching the LCD screen will still work just as well; in addition, the film will prevent dust from entering the screen, thereby avoiding compromising the touch sensitivity of the LCD screen.
2. Waterproof Protection
Water will bring great harm to the screen, which will be fatal; the consequences of turning on water and electricity at the same time are terrible. Remember to keep your hands moist and avoid touching the screen directly.
