What are the maintenance methods and precautions for industrial capacitive touch screens?

Today's life is inseparable from the electronic age, so many industrial capacitive touch screens have appeared around us. Its arrival has brought us a great deal in our lives, so we are very familiar with it. No matter what we use, we must pay attention to its maintenance, just like people need maintenance to maintain good skin. So, today I will come to learn with you the maintenance methods and precautions of industrial capacitive touch screens, which are as follows:

1. Capacitive screens usually need to be pasted, and a better film (double film) should be pasted. The SD20.20 specification that meets the ESD specification is approved by the US ESDA (Electrostatic Discharge Protection Association); the manufacturer’s approval specification is fully promoted in North America, It is common in Europe and Asia, and it is a control plan for electrostatic discharge (ESD) protection.

2. Organize the capacitive screen regularly, use the computer’s liquid crystal cleaning fluid (cannot use alcohol, furniture cleaning fluid) (PS: Originally, the capacitive screen can also be scrubbed with alcohol, but you should use pure medical alcohol to scrub the wine at home. Too much water is very simple to cause the capacitive screen to enter water. So don't complain about the machine oil scrubbed with alcohol. In addition, the scrubbing method must also be paid attention to, and a few must be scrubbed quietly.

3. Extremely afraid of static electricity: static electricity can easily break down the capacitive screen. Although the glass on the surface of the capacitive screen mobile phone has passed certain anti-static treatment, it does not mean that it can resist the static electricity of the human body in winter, and many people like to paste a defective screen sticker that simply causes static electricity on it... …Be careful if you run naked with your pockets. (A cloth cover is a good choice.)

4. Fear of conductive media such as oil and sweat: covering the screen will form a conductive layer, which will then cause the screen to drift. (So wash your hands clean when you are playing with your mobile phone)

5. Afraid of "high" temperature. The "high" temperature here is not to bake with fire, but to reach a temperature of about 40 degrees, which may cause the capacitive screen to drift. If it is at this temperature for a long time, the capacitive screen will be warped. Don't sunbathe, and don't stay in the high temperature sun for a long time. Usage (recommended, if the screen temperature is high during charging, please use the phone less to charge)

6. Fear of magnetic fields. Especially in the electromagnetic field, if the small magnet is placed on the capacitive screen for a while, the capacitive screen will temporarily fail (it may also cause damage). Do not approach the speakers or magnetic screwdrivers. (When you get home, don't just put your phone on the speaker.)

7. Fear of unstable voltage. Usually when the finger touches the capacitive screen, it will "suck" away a little bit of current, and then the screen will evenly transmit electricity from the four corners to the position where the thumb is, and use this for positioning, so the capacitive screen is unstable in the transmission voltage. Down, it will "drift" or even fail. (Charge immediately if the battery is less than 20%.)
