Abstract
A fingerprint-touch sensing apparatus includes a substrate, a sensing electrode layer, a plurality of electrode switch circuits, a plurality of capacitance-signal switch circuits respectively connected to a plurality of data lines and a capacitance-signal line, and a fingerprint-touch sensing control integrated circuit. The sensing electrode layer includes a plurality of sensing electrodes arranged in multiple columns and multiple rows. The fingerprint-touch sensing control integrated circuit controls the capacitance-signal switch circuits and the electrode switch circuits to select one or more sensing electrodes to conduct sensing, thus providing the flexible function of fingerprint sensing or touch sensing.
