How to repair the touch failure of industrial touch screen display?

by:Toponetech     2021-11-01
With the continuous development and innovation of technology, people’s living standards are getting higher and higher, touch screens are also widely used by people, bringing a lot of convenience to people’s work and life, and their applications in the market are also very hot. You can see it. So how to fix the problem of touch failure when industrial touch screen monitors are used in industry with touch function? 1. Failure analysis and treatment methods of resistive touch screen Failure 1: The mouse and arrow are inconsistent phenomenon: The position of the finger touch is inconsistent with the mouse arrow. Analysis: After installing the driver, the bullseye is not touched vertically when performing the calibration position. The signal line on the touch screen is in poor contact or disconnected. Solution: recalibrate the position; find the breakpoint and reconnect or replace the touch screen. Fault 2: Touch screen accuracy and deviation Phenomenon: the mouse arrow stays at a certain position when it is not touched, and the mouse arrow is located at the midpoint between the contact point and the original stay point when it is touched. Analysis: A foreign object (non-active touch) is pressing the effective working area of u200bu200bthe resistive touch screen. Treatment method: remove foreign objects in the effective working area of u200bu200bthe resistive touch screen. Fault 3: No response when touching the industrial display. Phenomenon: When touching the screen, the mouse arrow will not move and the position will not change. Analysis: There are many reasons for this phenomenon: (1) Touch screen failure (2) Touch screen control card failure. (3) The touch screen signal cable is faulty. (4) The serial port of the host is malfunctioning. (5) The computer's operating system is malfunctioning. (6) The touch screen driver is installed incorrectly. 2. Common faults and troubleshooting methods of resistive screens 1. The resistive screen touch mouse can only move in a small area, or when the driver is not allowed to be installed for the first time, this usually happens. Please run the touch screen calibration program. After changing the display resolution (startup process), you must also run the touch screen calibration procedure 2. The mouse is located at a certain point on the four sides of the display. This is because the touch area of u200bu200bthe resistive screen (the surface of the resistive screen is divided into a touch area and a non-touch area. There is no response when the non-touch area is clicked). The equivalent has been touched to a certain point. If the case shell presses the touch area, you can increase the distance between the case and the monitor screen. If the display case presses down on the touch area, you can try to loosen the screws of the display case. If it still does not work, please contact the supplier. The above is the fault analysis and solutions for the poor touch of the industrial display touch screen. The operator must standardize the operation, and when a fault is encountered, it must be solved by a professional. Do not disassemble the machine for inspection.
