3. Why does my touchscreen not respond to touch?
a. It may be that one of the wires connecting the touchscreen to the main unit is not connected. Please check the wiring.
b. It may be that the touchscreen driver was not installed with the corresponding serial port number of the actual installed touchscreen. Please reinstall the driver.
c. It may be that the host is a domestic original machine, and the operating system installed is an OEM version, adjusted by the manufacturer, causing non-standard serial communication, which is incompatible with the touchscreen driver. If possible, please format the hard drive and install the system before installing the touchscreen driver.
d. Check if the host has crashed. Check if the reflective stripes on the four edges of the touchscreen surface are scraped flat. Check if the connection between the touchscreen control cable and the host or control card is loose. For surface acoustic touchscreens, check if the four sensors located at the three corners of the screen are damaged, cracked, or contaminated by foreign objects. Check if the control cable is damaged, especially the control cable around the surface acoustic touchscreen and the parts connected to the sensors. Uninstall the touchscreen driver and reinstall it. Check if the host has been attacked by a virus.
4. Why is the response time of my touchscreen very long?
a. It may be that there are moving water droplets on the touchscreen that the touchscreen is responding to. Please wipe it with a dry, soft cloth.
b. It may be that the host is of too low a grade, and the clock frequency is too low. Please replace the host.
5. Why does my touchscreen have no response in certain areas?
a. It may be that the reflective stripes of the touchscreen are partially covered. Please wipe it with a dry, soft cloth.
b. It may be that the reflective stripes of the touchscreen have been scraped off in certain areas by hard objects, which cannot be repaired.
