Abstract

The invention discloses a shift register, a drive method thereof, a gate drive circuit and a display device. The shift register comprises a signal input unit, a pull-up node boosting unit, a pull-up node buck unit, a pull-down node boosting unit, a pull-down node buck unit, a pull-up unit and a pull-down unit. The charging time of a gate scanning line can be changed only by changing high-level input signal output time of a signal end without changing factors such as a clock signal, a circuit structure and a related production process, so that the shift register can be applied to a product with a large size, an ultrahigh resolution, a high-frame scanning frequency and a narrow frame, the gate drive difficulty of the product with the large size, the ultrahigh resolution, the high-frame scanning frequency and the narrow frame is effectively reduced, production cost is reduced, and product competitiveness is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a shift register, a driving method thereof, a gate driving circuit and a display device. Background technique [0002] In today's era of rapid technological development, liquid crystal displays have been widely used in electronic display products, such as televisions, computers, mobile phones and personal digital assistants. The liquid crystal display includes a data driving circuit (Source Driver), a gate driving circuit (Gate Driver), and a liquid crystal display. The liquid crystal display has a pixel array, and the gate drive circuit is used to sequentially turn on corresponding pixel rows in the pixel array, so as to transmit the pixel data output by the data drive circuit to the pixels, and then display the image to be displayed. At present, the gate driving circuit is mostly integrated inside the liquid crystal display to realize the narrow frame design of the liquid cry...
