5. The author mentioned before that once the system changes the display resolution, adjusts the screen size, or
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 it. However, When positioning, it is best to use a relatively thin pen or fingertips for positioning, so that it is more accurate.
6. The working environment of surface acoustic wave touch screen has high requirements. It must work in a clean
environment without dust pollution, and the dust on the surface of the touch screen must be cleaned regularly. Otherwise, the
dust in the air will cover the surroundings of the touch screen. Reflective streaks or transducers 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 will
easily mistakenly think that there is a hand touching it, causing the surface acoustic wave screen to be inaccurate. In addition,
when removing dirt on the touch screen surface, you can use a soft dry cloth or detergent to carefully wipe from the center of the
screen outward, or use a dry soft cloth dipped in industrial alcohol or glass cleaning fluid to clean the touch screen surface.
8. If the touch screen responds very slowly when you touch the surface acoustic wave touch screen with your hand or other
touching object, it means that the touch screen system is probably old, the internal clock frequency is too low, or there are water
droplets moving on the surface of the touch screen. If you want the touch screen to respond quickly, you must replace or upgrade
the system, or use a rag to wipe away the water droplets on the surface of the touch screen.
9. Touch screens generally use serial ports for signal transmission and take signals from the PS/2 port, while TPS screens
take power directly from the host power supply. If the indicator light does not light up, it means that the signal is not 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 we must replace the
control box. If replacing the control box still doesn”t work, it”s possible that the screen is pressed too tightly and you need to loosen the
screws around it slightly. Because the touch screen is made of special materials, it is not easily damaged. If the serial port is bad or disabled,
the driver will not be installed because the serial port will be automatically searched for when installing the driver. Even if it can be installed, the
mouse will not move or cannot be positioned. It is best not to use a serial port mouse to judge the
10. When you touch a certain position of the capacitive touch screen with your finger and the touch screen does not respond, it is
likely that the ITO coating corresponding to the touch position is damaged or scratched. The only way is to buy a new one. touchscreen.
11. When you touch a certain position of the surface acoustic wave touch screen with your finger and the touch screen does not respond,
it is likely that the reflection stripes corresponding to the touch position are partially covered or scraped off by a hard object. In the former case Just wipe
the touch location with a soft cloth. In the latter case, we can only buy a new touch screen.
12. If the direction of touch movement is to the left when the user is operating the touch screen, but the cursor of the system moves to the right, this fault may
be caused by the connector connecting the control box and the touch screen being connected incorrectly or the left and right positions of the touch screen being
13. After confirming that the connection to the keyboard port of the host is correctly connected, and that the serial port number selected during the driver installation
process and the serial port number actually connected to the touch screen are correct, if the surface acoustic wave screen touch screen still cannot work, you can reformat it.
hard drive and install the latest drivers required by the system.
