8-Wire Resistive Touch Screen
The 8-wire touch screen is basically a 4-wire on steroids. Each axes has 2 additional traces dividing the axes in half to improve accuracy and stability. These are typically glass bottom and film top. They can also be film + film. Applications where accuracy is crucial and recalibration is unacceptable are well suited for an 8 wire resistive touch screen. By having 4 additional traces the controller is able to automatically correct drift resulting from environmental issues and high usage.
