1. Why does the embedded industrial tablet computer touch screen all-in-one machine do not respond to touch?
1. It may be that the driver of the touch screen is not installed corresponding to the serial port number actually installed on the touch screen. Please reinstall the driver.
2. It may be that in the connection of the touch screen, one of the mainframe keyboard ports is not connected, please check the connection.
3. 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 drive the touch screen after installing the system.
2. Why does the embedded touch screen all-in-one have a long response time?
1. It is possible that the host grade is too low and the frequency is always too low. Please replace the host.
2. It may be 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.
3. Why is the embedded touch screen all-in-one machine inaccurate?
1. It is possible that the reflection stripes of the sonic screen have been slightly damaged and cannot be completely repaired.
2. After the sound wave screen has been used for a period of time, the reflective stripes around the screen are covered by dust. Please wipe it with a clean soft cloth, then restart the computer and recalibrate after power off.
4. Why can't the embedded touch screen all-in-one be calibrated?
1. It is possible that the touch screen control card does not receive the operation signal before the host starts to load the touch screen program. Please power off and restart the computer and recalibrate.
2. After using the sonic screen 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, then restart the computer and recalibrate after power off.
