Industrial touch display is a display with touch function used in industry. When the industrial touch display is working, there will be some failures. How to solve the problem when the touch is not sensitive?


       1. Analysis and treatment methods for the failure phenomenon of resistive touch screen


       Fault 1: The mouse does not coincide with the arrow


       Phenomenon: The position touched by the finger does not overlap with the mouse arrow.


       Analysis: After installing the driver, there is no vertical touch on the center of the bullseye when correcting the position. The signal line on the touch screen is in poor contact or open circuit.


       Solution: re-correct the position; find the breakpoint and reconnect or replace the touch screen.


       Fault 2: Accuracy and deviation of the touch screen

 

       Phenomenon: When not touching, the mouse arrow always stays at a certain position. When touching, the mouse arrow stays at the midpoint between the touch point and the original stay point.


       Analysis: A foreign body (non-active touch) is pressing the effective working area of the resistive touch screen.


       Treatment method: remove the foreign objects that are pressing on the effective working area of the resistive touch screen.


       Fault 3: No response to touch


       Phenomenon: When touching the screen, there is no movement of the mouse arrow and no position change occurs.


       Analysis: There are many reasons for this phenomenon. The following explains one by one:


       (1) The touch screen fails


       (2) The touch screen control card is malfunctioning.


       (3) The touch screen signal line is faulty.


       (4) The serial port of the host computer is malfunctioning.


       (5) The computer's operating system is malfunctioning.


       (6) The touch screen driver is installed incorrectly.


       2. Common faults and troubleshooting of resistive screens


       1. The resistive screen touch mouse only moves in a small area or the resistive touch screen is inaccurate


       Generally, this will happen when the driver is installed for the first time. Please run the touch screen calibration program. After changing the monitor resolution, you must also run the touch screen calibration program (start-program)


       2. The mouse always appears at a certain point on the four sides of the display because the touch area of the resistive screen (the surface of the resistive screen is divided into two parts, the touch area and the non-touch area, there is no response when clicking on the non-touch area) by the display shell or cabinet shell Suppressed, which is equivalent to a certain point being touched all the time. If the cabinet shell is pressing the touch area, you can increase the distance between the cabinet and the monitor screen. If the monitor shell is pressing the touch area, you can try to loosen the screws of the monitor shell a bit. If it still doesn't work, please Contact the industrial touch screen display manufacturer.
