Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0041] As mentioned in the background art, the frame area of ​​the existing display device includes a gate drive circuit for providing gate drive signals to the pixel units in the display area to scan the pixel units in the display area to achieve the purpose of image display. However, the existing gate driving circuit has relatively large driving delay, which reduces the performance of the display device.

[0042] Based on this, the embodiment of the present ...

Abstract

According to a gate driving circuit, a driving method thereof and a display device provided by the invention, a forward scanning trigger signal is directly accessed to a first-stage shifting register, so that the forward scanning trigger signal directly acts on the first-stage shifting register without passing through a first virtual shifting register, the driving delay problem of the gate driving circuit during forward scanning is reduced; and the Nth-stage shifting register is in direct contact with the reverse scanning trigger signal, so that the reverse scanning trigger signal directly acts on the Nth-stage shifting register without passing through the second virtual shifting register, and the problem of driving delay of the gate driving circuit during reverse scanning is solved. Therefore, according to the technical scheme provided by the invention, on the basis of ensuring that the gate driving circuit can realize bidirectional scanning, the driving delay of the gate driving circuit is reduced, and the performance of the display device is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a gate driving circuit, a driving method thereof, and a display device. Background technique [0002] The frame area of ​​the existing display device includes a gate drive circuit for providing gate drive signals to the pixel units in the display area to scan the pixel units in the display area to achieve the purpose of image display. However, the existing gate driving circuit has relatively large driving delay, which reduces the performance of the display device. Contents of the invention [0003] In view of this, the present invention provides a gate drive circuit and its drive method and display device, which effectively solve the technical problems existing in the prior art, and reduce the gate drive circuit on the basis of ensuring that the gate drive circuit can realize bidirectional scanning. The driving delay of the electrode driving circuit is improv...
