Tiankun Information touch screen industrial display equipment summarizes common common fault solutions of touch screens;
1. Inaccurate touch screen: A five-wire resistive touch screen cannot perform the corresponding operation normally when touching the part of the display screen with a finger. Fault analysis and treatment: This phenomenon may be a problem with the proofreading of the resistive screen. The screen calibration program can be run under the following conditions: (download the calibration program on the official website of Tiankun Information http://tkun.com/download.html) 1.1. Complete the installation of the driver software for the first time. 1.2. After changing the resolution or display mode of the monitor each time. 1.3. After changing the displayed display area each time. 1.4. After adjusting the frequency of the controller each time. 1.5. Every time the cursor cannot correspond to the touch point. 1.6. After calibration, the calibrated data is stored in the register of the controller, so there is no need to calibrate the screen every time the system is started. 2. The touch screen does not respond: The touch screen of the monitor does not work, and there is no response when touching any part. Failure analysis and processing: First check whether the wiring interfaces are loose, and then check whether there is a conflict between the serial port and the interrupt number. If there is a conflict, adjust the resources to avoid the conflict. Then check whether there are cracks on the surface of the touch screen. If there are cracks, return to the factory for replacement. If the above parts are normal, you can use the replacement method to check the touch screen, first replace the touch cable, then replace the serial cable, and finally replace the host. The following maintenance can be carried out: 2.1. Check whether the connecting wires of the touch screen are connected correctly. One end is connected to the host and the other end is connected to the display. Please check whether the ports are loose or unrecognizable. 2.2. If the above conditions are not confirmed, please delete the touch screen driver and restart the computer to reinstall the driver. 2.3. If the touch screen has been used for a long time (3-4 years) and it is found that some areas of the touch screen cannot be touched, it may be that the touch screen is broken. Please replace the touch screen. 3. The touch screen has a long response time: A touch screen, after touching the monitor screen with a finger, it takes a long time to respond. Fault analysis and processing: This may be caused by a virus on the host or system chaos. 3.1. First check whether the host has a virus, if so, kill the virus first. 3.2. If there is a problem with the system, check whether it can be adjusted, if not, reload the system. 3.3. If the problem still occurs, it can be returned to the factory for repair. 4. Part of the touch screen does not respond: A touch screen, after touching the monitor screen with a finger, there is no response in some places. Failure analysis and processing: 4.1. It is possible that part of the touch screen is scraped off by hard objects, which cannot be repaired. Please replace the touch screen 5. The touch screen is normal but the computer cannot be operated: A touch screen, everything is normal after the test itself, but after connecting the host, the computer cannot operate. Failure analysis and processing: 5.1. It is possible that before the host starts loading the touch screen driver, the touch screen control card receives the operation signal, just restart the computer after power off. 6. There is no response when the touch screen is started for the first time after installing the driver: For a touch screen, the touch screen becomes unresponsive the first time after installing the driver. Failure analysis and processing: 6.1. First confirm whether the touch screen wiring is connected correctly. If not, connect all the wiring correctly after shutting down. Then check whether there is a conflict between the device and the serial port resource in the host, check the hardware devices and adjust them.
8. The touch screen cannot be calibrated:
9. The mouse always stays on a certain point of the touch screen:
