Abstract

The invention provides a gate drive circuit, a drive method and a display device. The gate drive circuit comprises A gate drive sub-circuits and (A-1) signal transmission sub-circuits, wherein each signal transmission sub-circuit is arranged between every two adjacent gate drive sub-circuits; each gate drive sub-circuit comprises an output control unit and cascaded B-stage shifting register units which are sequentially arranged; each signal transmission sub-circuit comprises cascaded C-stage signal transmission units, and A, B and C are integers larger than one; each output control unit provides gate drive signals to corresponding B*D rows of gate lines according to output control signals input from an output control terminal and gate drive signals output from gate drive signal output ends of the B-stage shifting register units, and D is an integer larger than 1. The number of transistors in the gate drive circuit can be reduced, and realization of narrow bezel is facilitated.

Description

technical field [0001] The present invention relates to the technical field of display driving, in particular to a gate driving circuit, a driving method and a display device. Background technique [0002] With the rapid development of LCD (Liquid Crystal Display, liquid crystal display) technology, higher requirements are placed on the aesthetic requirements of the LCD panel. The width of the frame is also more and more valued by consumers. In a traditional gate drive circuit, each shift register unit has the same structure, and each shift register unit drives a row of gate lines. Due to the large number of TFT (Thin Film Transistor, Thin film transistor) tube, it is difficult to further compress the space occupied. Contents of the invention [0003] The main purpose of the present invention is to provide a gate drive circuit, a drive method and a display device, which solve the problems in the prior art that the number of transistors in the gate drive circuit cannot be...
