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.
