Abstract

The present disclosure provides a driving circuit and a driving method thereof, an array substrate, a display device, and a driving method thereof, and belongs to the technical field of display. The driving circuit is configured to drive a light-emitting element and a fingerprint detecting component, and includes a driving sub circuit, a data writing sub circuit, a first energy storage sub circuit, a detecting sub circuit and a data output sub circuit, wherein the driving sub circuit is configured to output the light-emitting drive current to the light-emitting element under the control of a driving node; the data writing sub circuit is configured to in response to a scan signal on a scan signal end, electrically connect the data input end and the driving node; the first energy storage subcircuit connects the driving node and the control signal end; the detecting sub circuit is configured to output a detecting current under the control of the output end of the fingerprint detecting component; the data output sub circuit is configured to output the detecting current to the data output end in response to the scan signal on the scan signal end. The driving circuit can reduce the complexity of the circuit of the display device in the display area and improve the resolution of the display device.

Description

technical field [0001] The present disclosure relates to the field of display technology, and in particular to a driving circuit and a driving method thereof, an array substrate, a display device and a driving method thereof. Background technique [0002] In the field of display, fingerprint identification technology has been more and more widely used. In the in-cell display panel with fingerprint recognition function, the driving circuit of the fingerprint recognition sensor and the driving circuit of the pixel are integrated in the same driving circuit layer, and the circuit of the display area of ​​the display panel is complicated, making it difficult to realize high resolution. [0003] The above information disclosed in this Background section is only for enhancement of understanding of the background of the disclosure and therefore it may contain information that does not form the prior art that is already known in the art to a person of ordinary skill in the art.
