摘要： A display device is provided. The display device includes: a display panel provided with a plurality of display electrodes, where the display electrodes are configured for displaying images, display electrodes located within a predetermined region of the display panel are defined as first electrodes, the first electrodes are configured for 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, and provide a fingerprint sensing signal to the first electrodes during the fingerprint sensing stage and perform a self-capacitance detection on the first electrodes, to implement the fingerprint sensing. A driving circuit, a method for driving the display device, a liquid crystal display device and an electronic apparatus including the display device are provided.
