Abstract:
A fingerprint sensing device comprises a plurality of sensing pads, a plurality of data lines, a shielding layer, and a plurality of auxiliary voltage lines. The data lines are separately and electrically connected to the sensing pads, and configured to provide a sensing voltage to the sensing pads. The shielding layer is disposed between the sensing pad and the data lines. The auxiliary voltage lines are separately and electrically connected to the sensing pads, configured to provide an auxiliary voltage to the sensing pads. The auxiliary voltage is different from the sensing voltage. When a first sensing pad receives the sensing voltage, a second sensing pad adjacent to the first sensing pad receives the auxiliary voltage.
