Industrial tablet computer is a type of industrial control computer, which is an all-in-one structure, with the host, LCD display, and touch screen integrated into one. Widely used in industrial automation, MES, robotics and other fields. The touch screen is the main input device for industrial tablets. Commonly used industrial tablets include capacitive screens and resistive screens. Capacitive screens work by sensing the human body's current, while resistive screens work by sensing pressure. What are the reasons for inaccurate touch control on industrial tablets?

1. System malfunction

If the system of an industrial tablet malfunctions, it may lead to inaccurate touch control. The reasons for system failures include installing incompatible applications, system upgrade failures, virus infections, etc.

2. Touch screen driver malfunction

The touch screen driver has been changed, uninstalled, or installed incorrectly.

3. Touch screen hardware malfunction

Touch screen hardware failure is a common cause of touch control failure. It may be a touch screen malfunction, loose or damaged connection wires, etc.

4. Hardware Conflict

The touch screen is based on the USB/serial protocol of an industrial motherboard. If a wireless mouse and keyboard are connected, touch screen functionality may be lost due to conflicting default input device settings. You can solve this by uninstalling the wireless device first and then having the system recognize it again.

How to solve the problem of inaccurate and unresponsive touch during operation?

1. Restart industrial tablet

If there is an inaccurate touch, you can try restarting the industrial tablet. If it is caused by a system malfunction, it is possible to solve the problem by restarting.

2. Reinstall touch screen driver

After restarting, the touch screen still doesn't work properly. Please reinstall the touch screen driver. When performing secondary calibration after installing the driver program, pay attention to the detailed content of the system error message. "Control card not found", "Touch screen not connected", etc. Check the corresponding components according to the prompts.

3. Check the touch screen wiring port

First, check whether the wiring interfaces of the touch screen are loose, connected correctly, and whether the wiring is damaged. Check if there are cracks or damages on the surface of the touch screen, and replace them promptly if found.

4. Replacing the touch screen

If the touch screen wiring is not faulty and the driver program is installed correctly, it may be a fault with the touch screen itself and a new touch screen needs to be replaced.
