Nowadays, various companies may encounter the purchase of industrial LCD screens. Do you know what methods are available when choosing industrial LCD screens? Here is a detailed introduction:
1. If you are using a capacitive LCD screen, it is recommended that you first install the drivers required for the capacitive LCD screen correctly according to the requirements of the manual, and then use your finger to click on the screen in turn. Start"/"Program"/"Microtouch Touchware" to run the screen calibration program. After the calibration is completed, the system will automatically store the calibrated data in the register of the controller. After restarting the system, there is no need to calibrate the screen.
2. When using a resistive LCD 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 LCD screen is pressed by other touch objects, for example, once the LCD screen is touched by the display housing or cabinet housing When pressed, it is equivalent to a certain point being touched all the time, then the coordinate position feedback to the controller is not accurate, and 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.
3. In order to ensure the normal operation of the LCD screen system, in addition to ensuring the correct installation of the system software, you must also remember not to install two or more LCD screen drivers on a host, which will easily lead to the system A conflict occurred during operation, which made the LCD screen system unable to work normally.
4. If you change the resolution or display mode of the LCD screen when you operate the capacitive LCD screen in the middle, or adjust the refresh frequency of the LCD screen controller yourself, you must feel that the cursor and the touch point cannot correspond to each other. Re-calibrate the LCD screen system.
5. 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, but when you are positioning, the most It is better to use a thinner pen or fingertip for positioning, so that it is more accurate.
6. If you touch the surface acoustic wave LCD screen with your hands or other touch objects, the LCD screen responds very slowly, which means that the LCD screen system is probably out of date, the internal clock frequency is too low, or the surface of the LCD screen has water drops. When moving, if you want the LCD screen to respond quickly, you must replace or upgrade the system again, or wipe off the water drops on the surface of the LCD screen with a cloth.
7. Do not let the surface of the LCD screen have water droplets or other soft things sticking to the surface, otherwise the LCD screen is easy to mistakenly believe that the surface acoustic wave screen is inaccurate due to hand touch. In addition, when cleaning the dirt on the surface of the LCD screen, you can use a soft dry cloth or cleaner to wipe from the center of the screen carefully, or use a dry soft cloth dipped in industrial alcohol or glass cleaning fluid to clean the surface of the LCD screen.
