Patent ID: 8154528

Claim:
A matrix sensing apparatus comprising: a plurality of driving lines for receiving a plurality of driving signals; a plurality of sensing lines for outputting a plurality of sensing signals; and a matrix sensing region comprising a plurality of sensing areas, each of the sensing areas comprising: a sensing unit for generating a corresponding sensing signal of the plurality of sensing signals; a first transistor comprising a first end electrically coupled to the sensing unit for receiving the corresponding sensing signal, a second end electrically coupled to a corresponding sensing line of the plurality of sensing lines, and a gate; and a second transistor comprising a first end electrically coupled to the gate of the first transistor, a gate electrically coupled to a first driving line of the plurality of driving lines for receiving a first driving signal of the plurality of driving signals, and a second end electrically coupled to a second driving line of the plurality of driving lines for receiving a second driving signal of the plurality of driving signals; wherein the first transistor and the second transistor control a signal connection between the sensing unit and the corresponding sensing line based on the first driving signal and the second driving signal.
