Analog 5-Wire Resistive Touch Screen
Unlike 4-wire Resistive touch screens, where the voltage is measured by both top and bottom layer, in case of 5-wire Resistive touch screens voltage is measured only by the bottom layer. It allows this type of touch screens to be comparatively more reliable and accurate.
