Fault 1: Touch deviation
Phenomenon: The position of the finger does not coincide with the mouse arrow.
Analysis: After installing the driver, there was no vertical touch to the bullseye center position when correcting the position. Solution: Recalibrate the position.
Fault 2: Touch deviation
Phenomenon: The touch in some areas is accurate, and the touch in some areas is biased.
Analysis: Surface sound wave touch screen Acoustic wave on the four periphery of the acoustic wave reflection stripes accumulated on a large amount of dust or scale, affecting the transmission of sound wave signals.
Solution: Clean the touch screen, pay special attention to clean the sound wave reflection stripes on the four sides of the touch screen, and disconnect the power supply of the touch screen control card when cleaning.
Fault 3: No response to touch
Phenomenon: When touching the screen, the mouse arrow does not move, and the position does not change.
Analysis: There are many reasons for this phenomenon, which are explained one by one:
(1) The dust or scale accumulated on the sound wave reflection stripes on the four periphery of the surface sound wave touch screen is very serious, resulting in the touch screen not working.
(2) The touch screen is malfunctioning.
(3) The touch screen control card is faulty.
(4) The touch screen signal line is faulty.
(5) The serial port of the computer host fails.
(6) The computer's operating system malfunctions.
(7) The touch screen driver is installed incorrectly.

Kunlun Tongtai touch screen - the advantages of surface acoustic wave touch screen
1. The optical performance is the best. The clarity and light transmittance are the highest, the reflection is the least, and there is no color distortion, this is because the sound wave screen body is pure glass, unlike the resistive screen with multiple layers of composite film; The capacitive screen is coated with a layer of film on the surface, and the light transmittance is worse.
2. Anti-scratch and anti-barbaric use ...
