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.
