Due to technical limitations and poor environmental adaptability, especially the surface acoustic wave screen, the screen will not be able to be used normally due to pollution such as water droplets and dust, so the touch screen also needs regular maintenance like ordinary machines. And since the touch screen is a highly integrated touch all-in-one machine with a variety of electrical equipment, the following issues should be paid attention to during use and maintenance.
1) Wipe the screen with a dry cloth every day before turning it on.
2) Water droplets or beverages falling on the screen will make the software stop responding. This is because water droplets and fingers have similar characteristics and need to be wiped off.
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 with a dry cloth.
4) Use glass cleaner to clean dirty fingerprints and oil stains on the touch screen.
5) Turn on and off the power in strict accordance with the regulations, that is, the order of turning on the power is: display, audio, host. Power off is done in reverse order.
6) A large number of temporary files are generated on the hard disk. If you frequently break points or directly shut down without exiting Windows, it will soon lead to hard disk errors. Therefore, it is necessary to run scandisk regularly to scan the hard disk for errors, and it is better to set a secret way in the application to exit the application and power off the windows, for example: click the four corners in the specified order.
7) Pure touch screen programs do not need a mouse cursor, and the cursor will only distract the user's attention.
8) The simplest anti-mouse mode that is enough for the application should be selected, because the complex mode needs to sacrifice delay and system resources.
9) In Windows, the user has a chance to enter other systems when launching slower applications. The solution is to modify the system. ini file: set shell=progman. exe (under windows3.x) or shell=explorer. exe (on windows95) is directly changed to . EXE. But the application should be able to exit windows directly, otherwise the system cannot exit.
10) Depending on the harsh environment, open the machine head regularly to clean the reflective stripes and inner surface of the touch screen. The specific method is: open the cover on both sides of the machine, you can find the mechanism that releases the lock tongue at the front of the machine head, and open the mechanism to release the lock tongue. Lift the front of the handpiece to see the touchscreen control card, unplug the touchscreen cable, and move the handpiece back to remove the handpiece and touchscreen. After carefully looking at the method of fixing the touch screen, remove the touch screen for cleaning, be careful not to use hard paper or hard cloth, and do not scratch the reflective stripes. Finally, restore the handpiece in reverse order and with the original structure.
