Five wires resistive touch screen
Dec 13, 2018


Five wires resistive touch screen use five-wire resistor technology the base of the touch screen adds the voltage field in two directions to the conductive face of the glass through a precise resistor network. We can simply understand that the voltage field in two directions is time-sharing and working on the same face, while the outer layer of nickel and gold conducting is only used as a pure conductor. The position of the touch point is measured by the method of detecting the X axis and Y axis voltage of the inner ITO contact point with touch time. The five-wire resistance touch screen inner layer ITO needs four lead wires, the outer layer is only one conductor, the touch screen leads the wire to have a total of 5. 


Five wires resistive touch features: high resolution, high speed transmission reaction. High surface hardness, reduce scratch, scratch and chemical treatment. The same point contact 30 million times can be used. Conductive glass as the substrate medium, one-time correction, high stability, never drift. Five-wire resistance touch screen has high price and high environmental requirements.

Different with five wires resistive touch, there is another type common four wires resistive touch screen.

The two layers of transparent metal layer of four-wire resistance technique work at a constant voltage of 5V: one vertical direction and one horizontal direction. A total of four cables are needed. 

Four wires resistive touch features: high resolution, high speed transmission reaction. Surface hardness treatment, reduce scratch, scratch and chemical treatment. With smooth surface and fog surface treatment. A correction, high stability, never drift.
