1. There is no response to touch after using it for a period of time
The touch screen will not respond after a period of normal use after being turned on. Touch screen fault analysis and processing are divided into the following three situations:
1) In some applications, due to poor grounding performance, the shell of the control box will be covered with a large amount of static electricity, which will affect the working electric field inside the control box, resulting in the gradual failure of the touch. At this time, use a wire to ground the shell of the control box and restart it.
2) Because the surface sound wave touch screen is covered with sound waves on the surface of the touch screen when working, if the touch screen is not wiped for a long time, it will cause too much dust to accumulate and block the reflection stripes of the wave, which will cause the touch screen to not work normally. For touch monitors, you can use a clean business card or paper to gently wipe off the dust from the surrounding reflective streaks through the gap between the front cover of the monitor and the industrial touch screen, and then start the computer fresh. For All-in-One Touchscreens, open the front cover of the monitor, wipe the dust off the surrounding reflective streaks with a clean towel, and then restart the computer.
3) Many touch all-in-one touch screen control boxes use the way of taking power from the all-in-one power supply instead of taking power from the host, so you should also check whether the 5V output of the all-in-one power supply is correct, sometimes the instantaneous current is too large, resulting in the fuse being burned, and the fuse needs to be replaced at this time.
Second, the touch screen is partially unresponsive
Touch screen, after touching the monitor screen with your finger, there is no response in some places. Analysis and treatment of local unresponsive faults of the touch screen: It may be that the reflective stripes of the touch screen are partially covered, and you can wipe them clean with a dry soft cloth. It is also possible that the reflective stripes of the touch screen are partially scraped off by a hard object and cannot be repaired.
3. The touch screen is normal but the computer cannot be operated
The touch screen is tested to be normal, but after connecting to the host, the computer cannot be operated. The touch screen is normal but the computer cannot be operated Fault analysis and processing: It may be that the touch screen control card receives the operation signal before the host starts to load the touch screen driver, and only needs to power off again and then start the computer. It's also possible that the touchscreen driver version is too low and you need to install the latest driver.
Fourth, the touch screen response time is very long
Touch screen, after touching the monitor screen with your finger, it takes a longer time to react. The touch screen has a long response timeFault analysis processing: It may be that there are moving water droplets stuck to the touch screen, just wipe them with a dry soft cloth. It is also possible that the grade of the host is too low, such as the clock frequency is too low, if this is the case, it is best to replace the host.
5. The first time the touch screen is activated, there is no response
The first time the touch screen is started after installing the driver, it is unresponsive, and the first time the touch screen is started after installing the driver, it is unresponsive. Touch screen fault analysis and processing: first confirm whether the touch screen line connection is correct, if not, should be turned off and connect all lines correctly. Then check whether there are any devices in the host that conflict with serial port resources, check each hardware device and adjust them.
6. The touch screen is not responding
The touch screen does not work, and there is no response to touch any part. Touch screen unresponsive fault analysis and processing: first check whether the wiring interface is loose, and then check whether there is a conflict between the serial port and the interrupt number, if there is a conflict, the resources should be adjusted to avoid the conflict. Then check whether there are cracks on the surface of the touch screen, and replace them in time if there are any. Check the surface of the touchscreen for dirt and dirt, and if so, remove it with a soft cloth. Check if the indicator light on the control box is working properly, when it is normal, the indicator light is green and flashing. If the above parts are normal, you can use the replacement method to check the touch screen, first replace the control box, then replace the industrial touch screen, and finally replace the main unit.
