What are the common faults of capacitive touchscreen? These failures can be overhauled as follows:
Fault phenomenon 1: LCD capacitor touch screen response time is very long.
A capacitive touch screen, after touching the display screen with your finger, takes a long time to respond.
Fault analysis and treatment methods:
It is possible that there are moving water droplets stuck to the capacitive touch screen and can be wiped with a soft dry cloth. It is also possible that the host grade is too low, such as the clock rate is too low, if this is the case, it is best to replace the host.
Fault phenomenon 2: local no response of LCD capacitor touch screen.
A capacitive touch screen, after touching the display screen with your finger, there is no response in the local area.
Fault analysis and treatment methods:
It is possible that the touch screen reflection stripes are partially covered and can be wiped clean with a dry soft cloth. It is also possible that the touch screen reflection stripes are partially scraped off by hard objects and will not be able to repair.
Fault phenomenon 3: LCD capacitor touch screen is normal but the computer can not operate.
A capacitive touch screen, after testing its own normal, but connected to the mainframe, the computer can not operate.
Fault analysis and treatment methods:
This may be before the host starts to load the touchscreen driver, the capacitive touchscreen control card receives the operation signal, just reboot the power off, and then start the computer. It is also possible that the touchscreen driver version is too low and requires the latest driver to be installed.
