Abstract:
An electronic device and a fingerprint sensing method are provided. The electronic device includes a display panel, a fingerprint sensor, and an integrated driver chip. The display panel includes a plurality of pixel units arranged in an array. The integrated driver chip integrates a display driver circuit and a fingerprint sensing circuit. When the pixel units of the display panel are in an undriven state and a finger object is in contact with a sensing area of the display panel to perform a fingerprint unlock operation, the display driver circuit drives at least a portion of the pixel units corresponding to the sensing area, so that at least a portion of the pixel units provide illumination light to the sensing area. The fingerprint sensing circuit drives the fingerprint sensor to capture a fingerprint feature image of the finger object.
