Due to technical limitations and poor adaptability to the environment, especially the surface acoustic screen, due to water droplets, dust and other pollution, the screen can not be used properly, so the touch screen also needs regular maintenance like ordinary machines. As the touch screen is a highly integrated touch machine with a variety of electrical equipment, the following problems should be paid attention to in the process of use and maintenance.

Use and maintenance should pay attention to:

1) Wipe the screen with a dry cloth every day before starting it.

2) Water droplets or drinks falling on the screen will cause the software to stop responding. This is because water droplets and fingers have similar characteristics, so they need to be wiped.

3) The touch screen controller can automatically judge the dust, but too much dust will reduce the sensitivity of the touch screen, just wipe the screen clean with a dry cloth.

4) Use glass cleaner to clean dirty hand marks and oil stains on the touch screen.

5) Strictly in accordance with the provisions of the switching power supply, that is, the order of opening the power supply is: display, audio, host. Turn off the power in reverse order.

6) A large number of temporary files are generated on the hard disk. If you break frequently or simply close Windows without exiting, hard disk errors can quickly result. Therefore, you need to run the ScanDisk command periodically to scan for disk errors. It is recommended to set up a secret way in the application to exit the application and close Windows. For example, tap all four corners in the prescribed order.

7) Pure touch screen applications do not require a mouse cursor, which will only distract the user.

8) A simple mouse-resistant mode should be selected, which is sufficient for the application, since the complex mode requires the sacrifice of latency and system resources.

9) In Windows, when a slower application starts, the user has the opportunity to enter another system. The solution is to modify the SYSTEM. Set up the shell= progman.ini file. Exe (on Windows 3.x) or shell= Explorer. Exe (on Windows 95) directly to. Exe file. But applications should be able to exit Windows directly, otherwise the system cannot exit.

10) Depending on the bad environment, open the nose regularly and clean the reflective strip and inner surface of the touch screen. The specific method is: open the lid on both sides of the machine, you can find the mechanism in front of the machine head to loosen the lock tongue, open the mechanism to loosen the lock tongue. Lift the front part of the nose, the touch screen control card can be seen, unplug the touch screen cable, move the nose backward, and remove the nose and touch screen. After carefully checking the fixing method of the touch screen, remove the touch screen and clean it. Be careful not to use stiff paper or cloth or scratch the reflective stripes. Then, the nose is restored to its original structure in reverse order.
