A. It may be that the reflective stripe around the acoustic screen is covered with dust after being used for a period of time. Please wipe it with a dry soft cloth. Then power off and restart the computer and recalibrate.
B. It is possible that the reflected fringes of the sonic screen have been slightly damaged and cannot be completely repaired
2. Why can't the touch screen be calibrated?
B. It is possible that after the acoustic wave screen has been in use for a period of time, the reflective stripe around the screen is covered with a large amount of dust. Although some areas can be operated, it cannot be calibrated.
3. Why does the touch screen not respond to touch?
A. It may be that in the connection of the touch screen, one of the connections connecting the keyboard port of the host is not connected. Please check the connection.
B. It may be that the driver of the touch screen does not have the serial port number corresponding to the actual installation of the touch screen, so please reinstall the driver.
C. It may be that the host machine is the originally installed machine made in China and the operating system installed is the OEM version, which has been adjusted by the manufacturer, resulting in non-standard serial port communication and incompatible with the touch screen drive. If feasible, please format the hard disk and drive the touch screen after installing the system.
D. Check whether the host machine has crashed. Check that the reflective stripes on the four edges of the touch screen surface have been scraped flat. Check whether the connection between the touch screen control cable and the host or control card is loose. For the surface acoustic screen, check the four sensors located at three corners of the screen for damage, cracks, or contamination with foreign matter. Check that the control cable is not broken, especially the control cable located around the screen and connected to the sensor. Uninstall the touch screen driver and reinstall it. Check to see if the host is infected by a virus.
4. Why does the touch screen have a long response time?
A. Moving water droplets may be stuck on the touch screen, and the touch screen responds to the operation of the water droplets. Please wipe with a dry soft cloth.
B. It may be that the host is too low grade and the clock frequency is too low. Please replace the host.
5. Why is there no local reaction on the touch screen?
A. It is possible that the reflective fringes of the touch screen are partially covered. Please wipe them with a dry soft cloth.
B. It is possible that the reflective fringes of the touch screen have been partially scraped off by hard objects and cannot be repaired.
6. Why is there nothing wrong with the touch screen, but it can't operate the computer?
A. It may be that before the host starts to load the touch screen driver, the touch screen control card receives the operation signal. Please restart the computer by power off.
