1. If you are using a capacitive LCD screen, it is recommended that you first correctly install the required driver program for the capacitive LCD screen according to the instructions when using it for the first time. Then, use your fingers to click on "Start"/"Program"/"Microtouchware" on the screen to run the screen calibration program. After calibration is completed, the system automatically stores the calibrated data in the controller's register. After restarting the system in the future, there is no need to calibrate the screen again.

2. When using a resistive LCD screen, if you find that the cursor is not moving or can only move in a local area, you can check whether the touch area of the LCD screen is pressed by other touch objects. For example, once the LCD screen is pressed by the display housing or cabinet housing, it is equivalent to a point being constantly touched, and the coordinate position feedback to the controller will be inaccurate, and the cursor will naturally not be positioned correctly. If the cabinet shell is pressing against the touch area, you can increase the distance between the cabinet and the monitor screen. If the monitor shell is pressing against the touch area, you can try loosening the screws of the monitor shell a little.

3. In order to ensure the normal operation of the LCD screen system, in addition to ensuring the correct installation of system software, it is also important to remember not to install two or more LCD screen drivers on a single host. This can easily lead to conflicts during system operation, making the LCD screen system unusable.

4. If during the operation of the capacitive LCD screen, the display resolution or mode of the LCD screen is changed again, or the refresh rate of the LCD screen controller is adjusted by oneself, and it is felt that the cursor and touch points cannot correspond, the LCD screen system must be recalibrated.

5. Once the system experiences inaccurate or drifting clicks when changing display resolution, adjusting screen size, or during the first installation, it is necessary to launch the built-in positioning program in the application to reposition. However, it is best to use a thinner pen or fingertip for accurate positioning.

6. If the surface acoustic wave LCD screen is touched with hands or other objects, and the LCD screen responds slowly, it is likely that the LCD screen system is outdated, the internal clock frequency is too low, or there are water droplets moving on the surface of the LCD screen. In order to restore fast response, the system must be replaced or upgraded, or the water droplets on the surface of the LCD screen must be wiped dry with a cloth.

7. Do not let water droplets or other soft objects stick to the surface of the LCD screen, otherwise the LCD screen is easily mistaken for being touched by hands, causing the surface acoustic wave screen to be inaccurate. In addition, when removing dirt from the surface of the LCD screen, you can carefully wipe it outwards from the center of the screen with a soft dry cloth or cleaning agent, or use a dry soft cloth dipped in industrial alcohol or glass cleaning solution to clean the surface of the LCD screen.
