Abstract

The invention provides a display device, a driving circuit and method therefor, and electronic equipment. The method comprises the steps: providing a fingerprint sensing signal to a part of a first electrode at a fingerprint sensing stage, carrying out the self-capacitance detection of the part of the first electrode till the fingerprint sensing signal is supplied to all first electrodes through a plurality of fingerprint sensing stages which are carried out sequentially, and carrying out the self-capacitance detection of all first electrodes, so as to achieve the fingerprint sensing; enabling each two fingerprint sensing stages to form one group of adjacent fingerprint sensing stages, and providing a display signal for a second electrode which is located in a row different from the plurality of first electrodes between at least one group of fingerprint sensing stages, so as to drive the second electrode located in the row different from the plurality of first electrodes to achieve image display. The circuit and method can improve the integration degree of the electronic equipment, and can prolong the service life of the electronic equipment.

Description
