TOUCH SENSOR WITH CONDUCTIVE POLYMER SWITCHES

摘要

The present invention is directed to touch sensors with arrays (140) of thin-film conductive polymer switches (e.g., diodes (145) or transistors (545)) that can be used to selectively apply voltage gradients across a resistive touch region (130) of the touch sensor substrate (120). Touches on the touch sensor can then be sensed by measuring the voltage at the touch location on the resistive touch region.
