The present application claims priority to Chinese patent application No. 201710585221.3, filed on Jul. 18, 2017, the entire disclosure of which is incorporated herein by reference as part of the present application.

TECHNICAL FIELD

Embodiments of the present disclosure relate to a scan driving circuit and a driving method thereof, and a display device.

BACKGROUND

Driving modes for a display panel mainly include an active matrix driving mode and a passive matrix driving mode. A main feature of the active matrix driving mode is to configure one active component for each pixel unit, to separately control each pixel unit. The active matrix driving mode has advantages such as low driving voltage, low power consumption, short response time, applicability to high-definition and large-sized display, and the like.

With development of a display technology, a display using an active matrix driving technology is getting matured day by day. Scanning modes of a gate active drive scanning circuit of the display are all co-directional sequential scanning, for example, progressive scanning or interlaced scanning, so that display frequencies of all display regions on the display panel of the display are fixed.

SUMMARY

At least an embodiment of the present disclosure provides a scan driving circuit, which comprises: a control circuit, a scanning circuit group and a first processing circuit group. The control circuit is configured to generate and output a keyword signal to the first processing circuit group, to control a scan order of respective scanning circuits in the scanning circuit group; and the first processing circuit group is configured to generate a scan enable signal according to the keyword signal, and output the scan enable signal to a scanning circuit corresponding to the keyword signal in the scanning circuit group.

At least an embodiment of the present disclosure further provides a display device, which comprises a display panel and the scan driving circuit according to any one of the embodiments of the present disclosure.

At least an embodiment of the present disclosure further provides a driving method for the scan driving circuit according to any one of the embodiments of the present disclosure, comprising: generating and outputting a keyword signal; and generating a scan enable signal according to the keyword signal, the scan enable signal being used for selecting a scanning circuit corresponding to the keyword signal to perform a scan operation.
