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: 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.
