How to Maintain Industrial Touch Screen Display

Ⅰ. Overview of industrial touchscreen displays

The touch screen system generally includes two parts: a touch screen controller and a touch detection device. The main function of the touch screen controller is to receive touch information from the touch point detection device, convert it into contact coordinates, then send it to the CPU. It can also receive and execute the commands sent by the CPU. The touch detection device is generally installed at the front end of the display, its main function is to detect the user's touch position and send it to the touch screen control card.

The industrial touch screen display has strong flexibility. It can replace or add functional modules according to the design requirements. It has strong scalability and can meet the complex process control process. It can even directly communicate with the PLC through the network system, which greatly facilitates the processing and transmission of control data, reducing the maintenance time.

Industrial touchscreen displays have provided great convenience to our work and life, and it has merged with our lives. The lifespan of the cost-effective touch screen display is relatively long, but we still need to maintain it.

Ⅱ. How to maintain industrial touchscreen displays

1. Do not use the industrial touch screen at high temperature

Do not use TFT color screen in a high temperature environment. When the ambient temperature reaches 40°C or above, LCD display panel will easily cause the capacitive screen of the touch screen to drift. If this is the case for a long time, it will cause serious damage or even scrapping of the touch screen, which will cause the company or individual It is very inconvenient to cause economic losses.

2. The industrial touch screen should not be at close distances to the strong magnetic field

The electromagnetic field must be avoided when the magnetic field is used, because the magnetic field will cause the temporary failure of the capacitive screen. However, you also need to pay attention to magnetic things such as audio, so as far as possible, don't let it close to the industrial touch screen display.

3. Avoid static effect of the industrial touch screen

The electrostatic effect is easy to penetrate the capacitive screen. Although the glass on the surface of the capacitive screen of the touch screen display has a certain anti-static treatment, it can only withstand static electricity under a certain strength, so when choosing a touch screen protective film, it must be Pay more attention to choosing protective films with strong anti-static ability as much as possible.

4. Be away from oil or sweat

If oil, sweat touch the industrial touch screen, a dense conductive layer will be formed on and cause the screen to drift. Therefore, the touch screen display should be kept away from oil and sweat.
