1. If you are using a capacitive touch screen, then it is recommended that you first install the driver required for the capacitive touch screen correctly according to the requirements of the manual, and then click "Start"/"Program"/"Microtouch Touchware" on the screen with your fingers to run the screen calibration program.
2. If you change the display resolution or display mode of the touch screen when you operate the capacitive touch screen in the middle of the operation, or if you feel that the cursor and the touch point cannot correspond to the touch point after adjusting the refresh rate of the touch screen controller by yourself, you must re-calibrate the touch screen system.
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 lead to conflicts when the system is running, so that the touch screen system can not be used normally.
4. When using the resistive touch screen, if you find that the cursor does not move or can only move in a local 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, it is equivalent to a certain point has been touched, then the coordinate position fed back to the controller is not accurate, and the cursor can not be positioned correctly. If the cabinet housing is pressing the touch area, you can adjust the distance between the cabinet and the monitor screen a little more, and if the monitor housing is pressing the touch area, you can try to loosen the screws of the monitor housing a little bit.
5. Once the system changes the display resolution, adjusts the screen size and installs for the first time, there will be inaccurate clicks or drift, you need to start the positioning program that comes with the application to reposition, 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 working environment of the surface acoustic wave touch screen is more demanding, it must work in a clean, no dust pollution environment, and the dust on the surface of the touch screen must be cleaned regularly, otherwise, when the dust in the air is covered on the reflective stripes or transducers around the touch screen, it will affect the correct positioning of the system.
7. 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 there is a hand touch, resulting in the inaccuracy of the surface sound wave screen. In addition, when removing dirt from the surface of the touchscreen, you can carefully wipe it from the center of the screen outward with a soft, dry cloth or detergent, or use a dry, soft cloth dipped in industrial alcohol or glass washer to clean the touchscreen surface.
8. If the touch screen is very slow to respond when touching the surface sound wave touch screen with hands or other touch objects, it is likely that the touch screen system is old, the internal clock frequency is too low, or because there are water droplets moving on the surface of the touch screen, in order to make the touch screen return to rapid response, the system must be replaced or upgraded, or the water droplets on the surface of the touch screen must be wiped dry with a rag.
