Patent ID: 8416213

Claim:
A resistive sensing apparatus, comprising: a plurality of first electrodes; a plurality of second electrodes; a sensing element array, disposed between the first electrodes and the second electrodes, for outputting at least one first inductive voltage after being touched; a first electrode scan driving circuit for sequentially scanning and driving the first electrodes, wherein the first electrode being driven is set to a constant high level output state, and the first electrode not being driven is set to a constant low level output state or a grounding state; a second electrode scan driving circuit for sequentially scanning and driving the second electrodes, wherein the second electrode being driven is set to a high impedance input state, and the second electrode not being driven is set to the constant low level output state or the grounding state; and a control circuit for controlling scan driving methods of the first electrode scan driving circuit and the second electrode scan driving circuit, wherein the at least one first inductive voltage changes when the first and second electrodes are scanned.
