    Resistive Touch Panel 7inch 4 wire resistive touch screen for Industrial display

    4-wire resistive is the most basic sensing method of resistive technology.

    Top and bottom transparent conductive sheets that have uniform resistance value, are facing each other with a gap. When the top sheet is touched, the touched point of the top sheet yields, and contact the bottom sheet. The contacted point is conducted, and its location is sensed.

    As feature of analog 4-ire resistive technology, one sheet has electrodes for the vertical direction while the other sheet has electrodes for the horizontal direction. Voltage of a touched point is measured by the other sheet. In this way, the touched point in X and Y directions is detected.

    How does a resistive touch screen work?
    In simple terms, a Resistive Touch Screen is a touch-sensitive computer display that responds by applying pressure.When contact is made to the surface of the touchscreen, these two sheets are pressed together. Each sheet has horizontal and vertical lines that register the precise location of the touch.

    Is there structural difference between 4-wire and 5-wire technologies?

    Just same as analog 4-wire resistive technology, an analog 5-wire resistive sensor consists of top and bottom sheets which are facing each other with a gap in between. Unlike analog 4-wire resistive technology, electrodes are placed on four corners of the bottom sheet in analog 5-wire technology. The sensing process is as below
