Abstract
A matrix sensing apparatus with architecture having reduced quantity of required sensing lines is disclosed. The matrix sensing apparatus includes a plurality of driving lines, a plurality of sensing lines and a matrix sensing region. The matrix sensing region includes a plurality of sensing areas. Each sensing area includes a first transistor, a second transistor, and a sensing unit for generating a sensing signal. The first transistor is coupled to the sensing unit and a corresponding sensing line. The second transistor is coupled to the first transistor, a first corresponding driving line and a second corresponding driving line. The first transistor together with the second transistor functions to control the signal connection between the sensing unit and the corresponding sensing line based on the driving signals of the first and second corresponding driving lines.
