1. If you re-change the display resolution or display mode of the touch screen when operating the capacitive touch screen in the middle, or adjust the refresh frequency of the touch screen controller by yourself, if you feel that the cursor and the touch point cannot correspond, you must reset the touch screen. The system performs a calibration operation.
2. Once the system changes the display resolution, adjusts the screen size, and installs for the first time, there will be inaccurate clicks or drifts. You need to start the positioning program that comes with the application to reposition. However, when positioning, the most important thing is It is better to use a relatively thin pen or fingertip for positioning, so that it is more accurate.
3. If you touch the surface acoustic wave touch screen with your hand or other touch objects, the touch screen responds very slowly, which indicates that the touch screen system is outdated, the internal clock frequency is too low, or there are water droplets moving on the touch screen surface. In order to restore the quick response of the touch screen, the system must be replaced or upgraded, or the water droplets on the surface of the touch screen must be wiped off with a rag.
4. Do not let water droplets or other soft things stick to the surface of the touch screen, otherwise the touch screen is easy to mistakenly think that the surface acoustic wave screen is inaccurate due to hand touch. In addition, when removing dirt on the touch screen surface, you can carefully wipe from the center of the screen outward with a soft dry cloth or detergent, or clean the touch screen surface with a dry soft cloth dipped in denatured alcohol or glass cleaning solution.
