Information

The structure of the capacitive touch panel is mainly to coat a transparent film body layer on the glass screen, and then add a protective glass outside the conductor layer. The double glass design can completely protect the conductor layer and the sensor, and at the same time, the light transmittance is higher and also Can better support multi-touch.

Precautions and common problems of capacitive touch panel:
1. If the user is using a capacitive touch panel, it is recommended that the user first install the driver required by the capacitive touch panel according to the requirements of the relevant manual when using it for the first time, and then click on the screen with a finger. "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, and there is no need to calibrate the screen again after restarting the system. .
2. If you change the resolution or display mode of the touch screen during the operation of the capacitive touch panel, or adjust the refresh frequency of the touch screen controller by yourself, you must re-align it if you feel that the cursor cannot correspond to the touch point. The touch screen 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, it is also necessary to remember not to install two or more touch screen drivers on a host, which will easily cause problems during system operation. Conflict, so that the touch screen system cannot be used normally.
4. Capacitive touch panel manufacturers tell you that when the touch screen is using a resistive touch screen, if you find that the cursor does not move or can only move in a local area, the user can check whether the touch area of ​​the touch screen is always pressed by other touch objects, such as once The touch screen is pressed by the display shell or the cabinet shell, which is equivalent to a certain point being touched all the time, then the coordinate position feedback to the controller is not accurate.
5. As mentioned earlier, 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 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. Capacitive touch panel manufacturers tell you not to let water droplets or other soft things stick to the surface of the touch screen, 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, the user 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 droplets on the touch screen surface.
9. Capacitive touch panel manufacturers tell you that touch screens generally use serial ports for signal transmission, and get signals from the PS/2 port, while TPS screens get power directly from the host's power supply. If the indicator light is not on, it means that the signal has not been obtained, and the PS/2 line on the control box may be broken. If the light is on but still does not flash, the control box is broken, so users must replace the control box. If the replacement of the control box still does not work, it may be that the screen is pressed too tightly, and the screws around it need to be loosened slightly. Because the touch screen is made of special materials, its body is not easily damaged. If the serial port is broken or disabled, the driver cannot be installed because the serial port will be searched automatically when the driver is installed. Even if it can be installed, the mouse does not move or cannot be positioned. The capacitive touch panel manufacturer tells you that it is best not to use a serial mouse to judge the quality of the serial port for the touch screen. It may be that the 9 serial ports use different methods for them. If the screen is pressed, or the ground wire is not connected properly, it will be unable to locate. If there are some areas that cannot be clicked or the response is slow, it may be affected by dust, and the casing needs to be disassembled to remove the dust.
10. When there is no response on the touch screen when touching a certain position of the capacitive touch panel with a finger, it is very likely that the corresponding touch position is inaccurate, and of course the cursor cannot be positioned correctly. The capacitive touch panel manufacturer tells you that if the touch screen is the cabinet shell pressing the touch area, users can increase the distance between the cabinet and the display screen. If the display shell presses the touch area, the user can try to screw the display shell Loosen it a little and try it.
