DRIVING DEVICE FOR DRIVING TOUCH DISPLAY PANEL WITH FINGERPRINT SENSING FUNCTION AND DRIVING METHOD FOR TOUCH DISPLAY PANEL

摘要

A driving device for driving a touch display panel with fingerprint sensing function and a driving method therefore are provided. The circuit includes a plurality of touch sensing input terminals, a plurality of fingerprint sensing input terminals, a first touch sensing circuit, a fingerprint sensing circuit, and a second touch sensing circuit. The second touch sensing circuit is coupled to a plurality of second touch sensing electrodes in a fingerprint sensor array of the touch display panel through at least a part of the plurality of fingerprint sensing input terminals. The second touch sensing circuit is configured to perform the second touch sensing operation according to the second touch sensing electrodes in the fingerprint sensor array for compensating a touch sensing result of the first touch sensing operation by the first touch sensing circuit.
