Due to improper operation or the influence of external factors during the operation of the industrial tablet computer, sometimes it will have a certain impact on the touch screen. How to solve the problem when there is a problem? What are the main problems?
1. Accurate touch in some areas, and deviation in some areas.
This phenomenon is caused by the accumulation of a large amount of dust or scale on the sound wave reflection stripes on the periphery of the surface acoustic wave touch screen, which affects the transmission of the sound wave signal.
Solution: Clean the touch screen, paying special attention to clean the sound wave reflection stripes on the four sides of the touch screen. When cleaning, disconnect the power supply of the touch screen control card.
2. The position touched by the finger does not overlap with the mouse arrow.
This phenomenon is mainly caused by not touching the center of the bullseye vertically when correcting the position after installing the driver. Solution: Re-correct the position.
When performing the first calibration after installing the driver, pay attention to the details of the system error. "No control card found", "Touch screen not connected", etc., check the corresponding parts according to the prompts.
