The touch screen is not sensitive to the processing skills of low sensitivity and slow response.
1. Why is the touch screen not allowed?
a. It may be that the reflective stripes around the screen are covered by dust after the sonic screen has been used for a period of time. Please wipe it with a dry soft cloth, then restart the computer and recalibrate after power off.
b. It is possible that the reflection stripes of the sound wave screen have been slightly damaged and cannot be completely repaired
2. Why can't the touch screen be calibrated?
a. It is possible that the touch screen control card receives an operation signal before the host starts to load the touch screen driver. Please power off and restart the computer and recalibrate.
b. It is possible that after the sonic screen has been used for a period of time, the reflective stripes around the screen are covered by a lot of dust. Although some areas can be operated, they cannot be calibrated. Please wipe with a dry soft cloth and then break it. Restart the computer and recalibrate
3. Why doesn't the touch screen respond to touch?
a. It is possible that one of the wires connected to the keyboard port of the host is not connected in the connection of the touch screen. Please check the connection.
b. It is possible that the driver of the touch screen is not installed corresponding to the serial port number actually installed on the touch screen. Please install the driver again.
c. It is possible that the host is a domestic original machine, and the installed operating system is an OEM version, which has been adjusted by the manufacturer, resulting in non-standard serial communication and incompatibility with the touch screen driver. If possible, please format the hard disk and install the system to drive touch screen.
d. Check whether the host is crashed. Check whether the reflective stripes on the four borders of the touch screen surface are scratched. Check whether the connection between the touch screen control cable and the host or control card is loose. For the surface acoustic wave screen, check whether the four sensors located on the three corners of the screen are damaged, cracked, or contaminated by foreign objects. Check whether the control cable is damaged, especially whether the control cable located around the screen of the surface acoustic wave touch screen and the part connected with the sensor are open. After uninstalling the touch screen driver, install it again. Check whether the host is infected by a virus
4. Why does the touch screen have a long response time?
a. It is possible that there are moving water droplets on the touch screen. The touch screen responds to the operation of the water droplets. Please wipe it with a dry soft cloth.
b. It is possible that the host grade is too low and the clock frequency is too low. Please replace the host.
5. Why doesn't the touch screen respond locally?
a. It is possible that the reflective stripes of the touch screen are partially covered. Please wipe it with a dry soft cloth.
b. It is possible that the reflective stripes of the touch screen are partially scraped off by hard objects and cannot be repaired.
6. Why is there no problem with the touch screen, but it just can't operate the computer?
a. It may be that the touch screen control card receives an operation signal before the host starts loading the touch screen driver. Please power off and restart the computer.
