Patent Images

1. A display device, comprising:

  • a display panel provided with a plurality of display electrodes, the display electrodes configured to display images, wherein the display electrodes located within a predetermined region of the display panel are defined as first electrodes, the first electrodes are further configured to implement a fingerprint sensing, and a stage during which the first electrodes perform the fingerprint sensing is defined as a fingerprint sensing stage; and

    a driving circuit configured to provide display signals to the display electrodes to display the images, provide a fingerprint sensing signal to the first electrodes and perform a self-capacitance detection on the first electrodes during the fingerprint sensing stage, to implement the fingerprint sensing.
