Abstract

The invention provides a shifting register unit, a driving method, a grid drive circuit and a display device. The shifting register unit comprises a pull-up node control subunit, a pull-down node control subunit and an output subunit, wherein the output subunit comprises N output modules, an nth output module controls an nth grid drive signal output end to be connected with an nth clock signal output end under control of a pull-up node in an output phase, the nth grid drive signal output end is controlled to output a second electric level in an nth output time segment of the output phase, and n is a positive integer which is less than or equal to N. The shifting register unit can help solve a problem that a conventional grid drive circuit is large in transistor quantity, and a narrow frame cannot be easily realized.

Description

technical field [0001] The invention relates to the technical field of display driving, in particular to a shift register unit, a driving method, a gate driving circuit and a display device. Background technique [0002] As mobile products such as mobile phones, tablet computers and other products become thinner and more refined, the frame of the screen is required to be narrower and narrower, and the development of circuits with fewer TFTs (Thin Film Transistors, thin film transistors) is essential for realizing ultra-narrow Borders are very important. However, in a traditional gate drive circuit, the first-stage shift register unit can only drive one row (stage) of gates. Therefore, the traditional gate drive circuit uses a large number of TFTs, which is not conducive to realizing a narrow border. Contents of the invention [0003] The main purpose of the present invention is to provide a shift register unit, a driving method, a gate driving circuit and a display device...
