There are usually four reasons for the failure of the touch display switch:

1. The switch button of the touch display has not been operated for a long time, and its internal contacts are oxidized, resulting in excessive contact resistance;

2. The touch display switch has poor contact caused by solder joints or loose connections or loose connectors;

3. The inside of the touch display button or the button board is stained, and there is a leakage point;

4. There is an error in the control program inside the touch display.

What should I do if the touch monitor switch fails? The supplier recommends that everyone try to repeatedly press the failed switch button many times, so that the switch contacts will operate frequently, which will promote the wear of the oxide layer and improve the contact. If it still doesn't work, you need to find a professional to solve it. In addition, the touch display also needs to be calibrated, specifically there are two situations where calibration is required:

①Calibration is required when the resolution of Industrial Touch Monitors is changed or replaced. The monitor sizes of different brands and models are obviously different, corresponding to different optimal resolutions. When the resolution is changed, the displayed image will be stretched horizontally or vertically, so that the touch screen coordinates do not correspond to the program coordinates, and calibration is required at this time.

②Replace the computer host, the relative position of the touch screen and the display has not changed. However, after the computer host is replaced, the corresponding coordinates cannot be guaranteed to be consistent with the original host. In this case, the touch display also needs to be calibrated.

The above content is about the cause analysis and solutions of the touch display switch failure, as well as the problem of calibration. Through these contents, everyone should have a better understanding of touch monitors. If you have any doubts or need to buy Industrial Monitors, please feel free to contact us.
