Detailed introduction to the working principle of four-wire resistive touch screen
I believe that many people have encountered situations where the touch screen cannot be used due to malfunction when using the touch
screen. This is mainly because the touch screen is a relatively sophisticated device. In addition, the touch screen is mostly open to the public. It
is used frequently and the quality of the users varies, resulting in frequent faults. Here are some common faults of the touch screen. Solutions and maintenance methods:
When the touch screen fails, you should first check whether the power supply of the control card is normal, whether the Windows driver is
installed normally, and then check whether the touch screen calibration under Windows is completed and whether the parameters in “Touchscreen
Control” are correct. You also need to check whether the serial port is normal and Is the serial port cable connected properly?
The following uses some examples to illustrate the diagnosis and treatment methods of touch screen faults.
1. The touch screen is not accurate
For a surface acoustic wave touch screen, the corresponding operation cannot be completed normally by touching the part of the display screen with your finger.
[Fault analysis and processing]
This phenomenon may be that after the sonic touch screen has been used for a period of time, the reflective stripes around the screen are covered with dust.
You can wipe it with a dry soft cloth, then cut off the power, restart the computer, and recalibrate. It is also possible that the reflective stripes of the sound wave screen
are slightly damaged, and if this happens it will not be completely repairable.
If it is a capacitive touch screen, you can run the screen calibration program under the following circumstances: (Start–Programs–Microtouch Touchware)
1) Complete the installation of the driver software for the first time.
2) After every time you change the resolution or display mode of your monitor.
3) Each time the displayed display area is changed.
4) After adjusting the frequency of the controller each time.
5) Every time the cursor and the touch point cannot correspond.
After calibration, the calibrated data is stored in the controller”s register, so there is no need to calibrate the screen every time the system is started.
2. The touch screen is unresponsive
One touch screen does not work and does not respond to any touch.
[Fault analysis and processing]
First check whether each wiring interface is loose, and then check whether there is a conflict between the serial port and interrupt number. If there is a
conflict, adjust the resources to avoid the conflict. Then check whether there are cracks on the surface of the touch screen. If there are cracks, replace them in
time. You also need to check whether there is dirt on the surface of the touch screen. If there is any dirt, use a soft cloth to remove it. Observe and check whethe
r the indicator light on the control box is working normally. When normal, the indicator light is green and flashes.
If the above parts are normal, you can use the replacement method to check the touch screen. First replace the control box, then replace the touch screen,
and finally replace the host.
If it is a surface acoustic wave touch screen, you can perform the following maintenance:
If it is a resistive touch screen, you can perform the following maintenance:
1) Check whether the touch screen connections are connected correctly, and whether one of the connections connected to the keyboard port of the host
computer (take the 5 volt touch screen operating voltage from the keyboard port) is connected. Please check the connections.
2) Observe the light of the touch screen control box. If it does not light up or lights up red, it means the control box is broken and please replace it.
3) If it is confirmed that the above situation is not the case, please delete the touch screen driver and restart the computer to reinstall the driver, or replace it with a newer and higher version driver.
