Resistance technology, touch screen

(1) Four-wire resistance touch screen

The touch screen is attached to the surface of the display and is used in conjunction with the display. Resistive touch screen is a piece of 4 layers of transparent composite film screen, is at the bottom of organic glass, glass or at the grass-roots level, the top layer is the outside surface after hardening treatment to smooth the scratch-resistant plastic layer, the middle one is two layers of metal conductive layer, respectively on grassroots inner surface, and the plastic layer in between two conductive layer, there are many small transparent isolation point separates them. When a finger touches the screen, the two conductive layers touch each other at the touch point. The two metal conductive layers of the touch screen are the two working faces of the touch screen. Each end of each working face is coated with a silver glue, which is called a pair of electrodes of the working face. If voltage is applied to the electrodes of a working face, uniform and continuous parallel voltage distribution will be formed on the working face.

(2) Five-wire resistive touch screen

Five line resistance touch screen technology base the voltage field of two direction by precision resistor network is added in conductive glass, we can simply interpreted as the direction of the two voltage field work time and work in the same plane, and the outer conductor used as more than just pure nickel gold conductive layer, five line of resistance touch screen is another proprietary technology by precision resistor network to adjust the inner ITO linear problems: caused by conductive coating thickness uneven likely voltage is not evenly distributed.
