The five-wire resistive touch screen and the four-wire resistive touch screen both adopt the principle of analog resistance, and their conventional fault characteristics are exactly the same as those of the four-wire resistor. If you are using a five-wire resistive touch screen, when there is an installation and maintenance problem, please determine and solve the problem in the following order.
Inaccurate screen position: Repositioning can be done via driver software.
Touch position and screen cursor upside down: When installing the touch screen, the position of the screen is reversed, please adjust the touch screen position according to the principle of right-hand position out.
The touchscreen display icon is always moved to a fixed corner: when the touchscreen monitor is installed, the display frame of that corner is pressed into the touch area, and the touchscreen position is adjusted or the screws are loosened at that position.
Touch screen cursor jumping in fixed position: A power supply or other high-frequency device is affecting the screen or controller. First, confirm that the outgoing wire of the touch screen leaves the high-voltage coil and is insulated from the display device; Second, confirm that the control card is insulated and leave the high-radiation parts such as the display circuit board and the deflection coil inside the display.
When the touchscreen control card is not installed in the LCD display, the screen produces a cursor jump: it may be the PIN of the touchscreen, i.e., the flat cable that connects from the touchscreen next to the discharged part of the edge source of the display. Workaround: See if you can move out of the PIN's location; If you have difficulty moving the PIN out, use thickened insulating tape under the PIN to isolate the PIN from the discharge portion of the monitor.
