Embodiment Construction

[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0043] As mentioned in the background, the scanning circuit in the existing display panel occupies a relatively large frame area, making it difficult for the display panel to achieve a narrow frame. The inventors found that in the existing display panel, the scanning circuit usually includes a relatively large number of thin film transistors and capacitors, such as the commonly used 8T2C scanning circuit, that is, a scanning circuit including 8 thin film transistors and 2 capacitors, and the scanning circuit The l...

Abstract

The embodiment of the present invention discloses a scanning circuit and its driving method, a display panel and a display device, wherein the scanning circuit includes a first output control module, a second output control module, and an output module; through the first output control module and the second output The control module controls the output module to complete the stable output of the scan signal, and the number of components required by each module is small, which is conducive to the realization of a narrow frame.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular, to a scanning circuit and a driving method thereof, a display panel and a display device. Background technique [0002] With the development of display technology, narrow bezels of display panels have become a major development trend. [0003] A display panel generally includes a scanning circuit, which occupies a frame area. In existing display panels, the scanning circuit occupies a large frame area, making it difficult for a display panel to achieve a narrow frame. Contents of the invention [0004] Embodiments of the present invention provide a scanning circuit and its driving method, a display panel and a display device, so as to reduce the number of devices in the scanning circuit and realize narrow borders. [0005] In the first aspect, an embodiment of the present invention provides a scanning circuit, including a first output control modul...
