When humanity enters the era of intelligent technology, the full touch LCD screen with capacitors and resistors makes our lives and work more convenient. However, there may be times when the screen malfunctions, and the next step is to repair the malfunction. The editor summarized the knowledge about damage, repair, and maintenance of touch LCD screens, which can help everyone learn better care for touch LCD screens without delaying normal work demonstrations and daily needs.
1. The cause of static electricity generation. Usually touchable LCD screens are capacitive screens, and the positioning of the touch screen is achieved through an electric field, resulting in static electricity and discharge. LCD touch screens can produce a "drift" screen effect.
2. Physical reasons. The so-called physical damage refers to the direct impact of hard objects on the LCD screen, such as impact. This is the cause of direct damage to the touch LCD screen, and even the occurrence of direct scrapping of the touch LCD screen.
3. Other reasons. Other conductive substances can also cause damage to the touch LCD screen, and water, steam, and sweat stains can damage the touch screen circuit, resulting in the screen not working properly.
1. It is necessary to maintain the touch LCD screen professionally. First, determine the cause of the accident - which aspect is the cause of the damage to the touch LCD screen, in order to accurately determine where the LCD screen needs to be repaired, and then repair or replace internal parts;
2. If the LCD screen is damaged due to a circuit malfunction, the external connection line of the LCD screen can be repaired; If the LCD screen is damaged, the capacitor LCD screen or internal structural components can be replaced according to the situation; The problem of LCD screen damage caused by liquid and gas infiltration requires cleaning the LCD screen and replacing some burnt out parts if necessary.
1. Film protection.
The tempered glass film developed for LCD screens has the best protective effect. Strong external impacts can damage tempered glass, but the touch LCD screen will still be as user-friendly as before; In addition, the film can also prevent dust from entering the screen, thereby avoiding damaging the touch sensitivity of the LCD screen.
2. Waterproof protection.
Water can bring great harm to the screen, and this harm will be fatal; The consequences of turning on water and electricity simultaneously are terrifying. Remember to keep your hands moist and avoid direct contact with the screen; Where there is a water vapor LCD screen, it cannot be accessed. The water vapor flows freely, making it easy for the LCD screen to float in the water
In daily life, it is an inseparable helper for us, so we must cherish it during use!
