ABSTRACT:
A touch sensor device is provided that that uses an edge electrode set to provide an improved effective area. Specifically, the touch sensor device includes an edge electrode set that together substantially surround a perimeter of sensing. The edge electrode set increases the effective sensing area of the touch sensor device, and thus can be used to improve the space efficiency of the touch sensor device.
