In the field of industrial engineering, after the industrial touch display is used for a period of time, the click accuracy sometimes decreases, and the cursor is difficult to locate, resulting in the situation that it cannot be used normally. Failure analysis and handling method:
1. Run the touch screen calibration program.
2. If this problem occurs with a newly purchased industrial touch display, it may be that the touch display driver is installed abnormally. You can delete the driver, disconnect the power supply for more than 5 seconds, and reinstall the driver after booting.
3. If the above two methods cannot eliminate the fault, it may be that the industrial touch display has been damaged during transportation or the working environment and cannot be completely repaired; it can deviate from the calibration in the opposite direction (relative to the direction that deviates from the cursor). Bullseye for positioning.
4. There are water droplets, oil stains or other things sticking to the surface of the industrial touch display, and the touch screen mistakenly judges that there is a hand touch and the action signal is received incorrectly, just remove it.
5. Resistive industrial touch displays have certain limitations. ITO on the surface of the film will lead to a change in resistance after a long time and will be cheaper.
