Infrared touch screen fault type and troubleshooting method

Source: KONWHAI TOUCHAuthor: nick Date: 2019-02-26 Click:

  •      The infrared technology touch screen is composed of infrared emitting and receiving sensing elements mounted on the outer frame of the touch screen. On the surface of the screen, an infrared detecting net is formed, and any touch object can change the infrared rays on the contacts to realize the touch screen operation.
  •  
  •      The infrared touch screen is implemented in a similar way to surface acoustic wave touch, using infrared emitting and receiving sensing components. These components form an infrared detection net on the surface of the screen, and an object (such as a finger) that is touch-operated can change the infrared rays of the electric shock, and is converted into a coordinate position of the touch to achieve an operational response. In the infrared touch screen, the circuit board device arranged on the four sides of the screen has an infrared transmitting tube and an infrared receiving tube, corresponding to forming an infrared matrix intersecting horizontally and vertically.

  •      Touch one machine will encounter various faults when it is used. KONWHAI Xiaobian introduces the fault type and troubleshooting method of infrared touch screen.

  • Infrared touch screen fault type and troubleshooting method

  •  
  •   Infrared touch screen fault type and troubleshooting method:  
  •  
  • 1. Infrared can not be identified
  •  
  •      Cause of the fault: The USB cable is too long to cause a voltage drop, the signal quality is degraded or the data is lost.
  •  
  •      Processing method: The USB cable is controlled within 5m. If the USB cable is more than 5m, it is recommended to use the USB HUB.
  •  
  • 2. Infrared disconnection
  •  
  •      The cause of the failure:
  •  
  •      a. The performance of the receiving tube is degraded, resulting in incomplete reception;
  •  
  •      b. During the booting process of the PC, there may be foreign matter blocking the infrared rays on the filter strip of the infrared touch screen.
  •  
  • 3. Infrared jumper
  •  
  •      The cause of the fault: It may be that the PC hardware and the system cause an infrared jumper.
  •  
  •      Processing method:
  •  
  •      a. Do not use the touch screen during the boot process, and the system will run normally after 60 seconds;
  •  
  •      b. Clean the surface and the foreign matter and dust on the infrared filter strip every day;
  •  
  •      c. Replace the receiving tube with reduced performance or the launch tube.
  •  
  •      The above is the explanation of the type and troubleshooting of the infrared touch screen. When the user purchases the touch-one machine and the touch-type fault occurs during use, it can be easily solved by following the above steps. If you want to know more about the technical problems related to the touch-one machine, please collect our official website and pay attention to it from time to time.
