    Abstract: An electronic circuit adapted to drive a display panel is provided. The display panel includes touch sensors and fingerprint sensors. The electronic circuit includes a touch sensing circuit, a fingerprint sensing circuit and a display driving circuit. The touch sensing circuit senses a touch of a finger and determines a first area corresponding to the touch on the display panel. The fingerprint sensing circuit senses a fingerprint image of the finger corresponding to the first area. The display driving circuit drives pixels of the first area with respective first gray levels and pixels of a second area outside the first area with respective second gray levels. The display driving circuit processes respective third gray levels to obtain the respective second gray levels. The display driving circuit generates gamma voltages corresponding to the respective first gray levels and the respective second gray levels according to the same gamma curve.

    Abstract: 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.

    Abstract: An electronic circuit for driving a panel including touch sensors and fingerprint sensors is provided. The electronic circuit includes a touch sensing circuit, a fingerprint sensing circuit and a display driving circuit. The touch sensing circuit senses a touch of a finger and determines a first area corresponding to the touch on the panel. The fingerprint sensing circuit senses a fingerprint image of the finger corresponding to the first area of the panel. The display driving circuit drives pixels over the panel with respective first gray levels during a first phase, and drives pixels of the first area with respective second gray levels and pixels of a second area outside the first area with respective third gray levels during a second phase. The respective second gray levels are higher than the respective first gray levels, and the respective third gray levels are lower than the respective second gray levels.
