Third, the common fault and elimination of the resistance screen

- Jul 26, 2019-

1. The touch screen touch mouse only moves in a small area or the resistive touch screen is not allowed. Generally, this happens when the driver is installed for the first time. Please run the touch screen calibration program. The touch screen calibration procedure (start-program) must also be run after changing the display resolution. 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, and clicking on the non-touch area is not responsive) is the display case or the cabinet case. Pressed, it is equivalent to a point that has been touched. If the cabinet case is pressed against the touch area, you can increase the distance between the cabinet and the monitor screen. If the display case is pressed against the touch area, you can try to loosen the screws on the display case. If not, please Contact our technical department.

    3. The mouse moves in the opposite direction to the hand, which is the four-wire connector connected to the touch screen control box and the touch screen.

    4. Touch no response to check whether the connection of the touch screen is connected. One of the connections to the keyboard port of the host (take the 5 volt touch screen working voltage from the keyboard port) is not connected. Please check the connection to observe the touch screen control box light, if not If the light is on or off, the control box is broken. Please replace it. If the confirmation is not the above, please remove the touch screen driver and restart the computer to reinstall the driver, or replace the driver with a newer version.

    Whether the device conflicts with the serial port resource in the host to check each hardware device and adjust it. For example, after some NICs are installed, the default IRQ is 3, which conflicts with the IRQ of COM2. In this case, the IRQ of the NIC should be changed to the unused IRQ. It may also be that the computer motherboard and the touch screen control box are not compatible. Please replace the host or motherboard. If the touch screen is used for a long period of time and some areas of the touch screen cannot be touched, it may be that the touch screen is broken, please replace the touch screen.
