Embodiment Construction

[0036] 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 part of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0037] In the prior art, by adding a clock signal line (CLK line), the pre-charging and charging time of the GOA circuit is lengthened, and the pre-charging time of the pixels is also lengthened, which can improve the display effect of the display device. However, in the connection mode of the existing gate drive circuit in the multi-phase circuit (that is, multiple CLK signal lines are respectively connected to the shift register unit), the four-phase ...

Abstract

The invention provides a grid driving circuit and a driving method thereof, and a display device. The grid driving circuit comprises N stages of orderly cascaded shifting register units; the grid driving circuit further comprises 2M clock signal lines, and a frame starting signal line, wherein clock signal ends of the N stages of orderly cascaded shifting register units are connected with 2M clocksignal lines; M continuous clock signa lines are orderly connected with input ends of front M stages of shifting register units and used for providing pull-up signals for the front M stages of shifting register units, N is the integer time of the 2M, and M is positive integer greater than or equal to 1; the frame starting signal line is used for controlling the on or off between M continuous clock signa lines and the input ends of front M stages of shifting register units. Through the grid driving circuit and the driving method thereof and the display device provided by the invention, a narrow-frame design of the display device can be convenient.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a gate driving circuit, a driving method thereof, and a display device. Background technique [0002] Gate Drive on Array (GOA for short) refers to a shift register in which a gate drive of a Liquid Crystal Display (LCD for short) is integrated on a glass substrate. The GOA circuit is connected to the gate lines of the array substrate, and serves as a shift register to control gate line signals. [0003] In the prior art, by adding a clock signal line (CLK line), the pre-charging and charging time of the GOA circuit is prolonged, and the pre-charging time of the pixels is also lengthened, which can improve the display effect of the display device. However, the existing connection method needs to increase the frame start signal line (STV line) correspondingly while increasing the CLK line, which is not conducive to the narrow frame trend of the display device.
