TOUCH SENSOR FOR A DISPLAY SCREEN OF AN ELECTRONIC DEVICE

摘要

A touch sensor for mounting over a display screen of an electronic device is provided. The touch senor includes: an elongate input pad formed in a layer of transparent conductive material on a transparent substrate, the input pad tapering from a broad end to a narrow end to provide an input pad capacitance that varies with location of a touch over the input pad; and, a contact for coupling the input pad to a processor.
