4-, 5-, and 8-Wire Technology
Resistive analog touch screens are normally available with 4-, 5-, and 8-wire circuitry.
4-Wire Touch Screen
4-wire touch screens are suitable for small or medium sized products such as PDAs and hand-held systems. These panels utilize X+, X-, Y+ and Y- lead outs at the four edges of the screen. When contact is made, X/Y read-outs are then read by the controller and converted into the correct coordinates.
5-Wire Touch Screen
5-wire touch screens can be produced in screen sizes from 3” to 24”. Resistive touch screens are suitable in many different systems and environments.
In a 5-wire touch screen, the top layer is a sensor layer while the main circuitry is located in the layer underneath.
8-Wire Touch Screen
The 8-wire circuit structure is well suited for screens from 6” to 22”. Functionality is much like that of 4-wire circuitry; with the major difference being that an 8-wire structure offers 4 additional screen read-outs and circuit protection. These additional read-outs can be used to further adjust for possible distortion on the corners or edges of a larger screen.
