After knowing the working principle of the touch screen, let's talk about how to operate the touch screen in detail! In order to better help you operate the touch screen, the author summarizes the following operation methods and techniques:
1. If you are using a capacitive touch screen, it is recommended that when you use it for the first time, first install the drivers required for the capacitive touch screen according to the instructions, and then click "start" on the screen with your finger. /"Program"/"Microtouch Touchware" to run the screen calibration program. After the calibration is completed, the system automatically stores the calibrated data in the register of the controller. After restarting the system, there is no need to calibrate the screen again.
2. If you change the display resolution or display mode of the touch screen when you operate the capacitive touch screen in the middle, or adjust the refresh frequency of the touch screen controller by yourself, you must re-align the touch screen when you feel that the cursor and the touch point cannot correspond to each other. The system performs calibration operations.
3. In order to ensure the normal operation of the touch screen system, in addition to ensuring the correct installation of the system software, you must also remember not to install two or more touch screen drivers on a host, which will easily cause the system to run. Conflict occurred, so that the touch screen system cannot be used normally.
4. When using a resistive touch screen, if you find that the cursor does not move or can only move in a partial area, you can check whether the touch area of the touch screen is always pressed by other touch objects, for example, once the touch screen is pressed by the display shell or cabinet shell Live, it is equivalent to a certain point has been touched, then the coordinate position feedback to the controller is not accurate, of course the cursor cannot be positioned correctly. If the cabinet shell presses the touch area, you can increase the distance between the cabinet and the monitor screen. If the monitor shell presses the touch area, you can try to loosen the screws of the monitor shell a bit.
5. The author mentioned earlier that once the system changes the display resolution, adjusts the screen size, and the first installation, there will be inaccurate clicks or drift. You need to start the positioning program in the application to reposition it, but When you are positioning, it is best to use a thinner pen or fingertip for positioning, so that it is more accurate.
6. The surface acoustic wave touch screen requires high working environment. It must work in a clean and dust-free environment, and the dust on the surface of the touch screen must be cleaned regularly. Otherwise, the dust in the air covers the surrounding area of the touch screen. When reflecting stripes or transducers, it will affect the correct positioning of the system.
7. Do not let the touch screen surface have water droplets or other soft things sticking to the surface, otherwise the touch screen is easy to mistakenly believe that the surface acoustic wave screen is inaccurate due to hand touch. In addition, when removing dirt on the surface of the touch screen, you can wipe the surface of the touch screen carefully with a soft dry cloth or detergent from the center of the screen, or use a dry soft cloth dipped in industrial alcohol or glass cleaning fluid to clean the surface of the touch screen.
8. If you touch the surface acoustic wave touch screen with your hands or other touch objects, the touch screen responds very slowly. This indicates that the touch screen system is probably out of date, the internal clock frequency is too low, or the water drops on the surface of the touch screen are moving. If you want the touch screen to respond quickly, you must replace or upgrade the system again, or use a rag to dry the water drops on the touch screen surface
