When all human beings enter the era of intelligent technology, the full-touch LCD screen of capacitive resistance makes our life and work more convenient. However, when the screen fails, the next step is to repair the fault. The editor summarizes the knowledge of touch LCD screen about damage, repair and maintenance can help everyone learn better care of touch LCD screen, it will not delay normal work presentations and life needs.
1: Cause of damage
1. The cause of static electricity. Usually touchable LCD screens They are capacitive screens, the positioning of the touch screen is done by an electric field, so static electricity and discharge are generated, and LCD touch screens have 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 screen, and water, water vapor and perspiration can damage the touch screen circuit, thus causing the screen to not work properly.
Two: screen maintenance steps
1. Professional maintenance of the touch LCD screen is required, first determine the cause of the accident - what is the cause of the damage to the touch LCD screen, so as to accurately determine where the LCD screen needs to be repaired, and then repair or replace the internal parts;
2. If the LCD screen is damaged due to circuit failure, the external connection circuit of the LCD screen can be repaired; and if the LCD screen is damaged, the capacitor LCD screen or internal structural components can be replaced according to the situation; the LCD screen is damaged due to liquid and gas penetration. Clean the LCD screen to dry and replace some burnt parts if necessary.
Three: maintenance
1. Film protection.
The tempered glass film developed for the LCD screen has the best protection effect. Strong external shocks can damage the tempered glass, but the touch LCD screen will still work as well as before; in addition, the film also prevents dust from entering the screen, thereby avoiding damage to the touch sensitivity of the LCD screen.
2. Waterproof protection.
Water will bring great harm to the screen, this harm will be fatal; the consequences of turning on the water and electricity at the same time are terrible. Remember to keep your hands wet and avoid direct contact with the screen; no water vapor can enter the LCD screen. The water vapor flows freely, and it is easy to float the LCD screen in the water
