The touch screen may be disturbed by power interference when working, which may cause the touch screen to not work properly or produce problems such as false touch. Here are some solutions as following.
>>Make sure the power line is correct.
Touch screens require stable power supply. We must make sure the power lines are properly connected and not damaged. Moreover, the power line should be away from other high-power equipment, such as motors, frequency converters, etc., to avoid electromagnetic interference.
>>Use an anti-interference power supply.
Anti-interference power supply can be used to provide a stable power supply and prevent external power interference from affecting the touch screen work. Anti-interference power supply usually use special filters and suppression circuits to reduce power supply noise and electromagnetic interference.
>>Add EMI shielding material.
Shielding materials, such as aluminum foil or electromagnetic wave shielding materials, can be added between the touch screen and other devices to prevent electromagnetic waves from interfering the normal operation of the touch screen.
>>Modify the software.
In terms of software, we can try to modify the driver software of the touch screen controller, and add some anti-interference code to cope with problems such as power interference.
>>Use capacitive touch screen.
Compared with the resistive touch screen, the capacitive touch screen has stronger anti-interference ability because it detects the touch signal by sensing the object being touched, does not require physical pressure trigger, and is not easily affected by external physical forces.
In short, in order to solve the problem of touch screen power interference, it is necessary to take a series of measures from the aspects of hardware, software and materials to improve the stability and anti-interference ability of touch screen.
