    Abstract: Disclosed herein includes a method, an apparatus, a display device and storage medium storing computer executable instructions for fingerprint recognition. The method may comprise turning on a first subset of a plurality of light sources located on an apparatus, capturing a first fingerprint acquisition frame using a plurality of image sensors on the apparatus, turning on a second subset of the plurality of light sources, and capturing a second fingerprint acquisition frame using the plurality of image sensors. The first fingerprint acquisition frame may include a first set of valid image zones and a first set of invalid image zones. The second fingerprint acquisition frame may include a second set of valid image zones and a second set of invalid image zones. The second set of valid image zones at least partially covers areas of a finger touching interface different from the first set of valid image zones.

    Abstract: The present disclosure provides a fingerprint sensing sub-circuit, a fingerprint sensing circuit, a fingerprint recognition method, a sensor, a touch display panel and a display device. The fingerprint sensing sub-circuit includes an acoustic wave generation circuit and an acoustic wave reception circuit. The acoustic wave generation circuit is configured to generate an ultrasonic wave. The acoustic wave reception circuit is configured to collect a voltage signal, convert the voltage signal into a current signal, and output the current signal to a signal output end. The acoustic wave generation circuit and the acoustic wave reception circuit are separated from each other, so that the fingerprint sensing sub-circuit operates in a mode where a transmitting operation and a receiving operation are separated from each other.
