Abstract

The invention provides a shifting register unit, a driving method, a grid driving circuit and a display device. The shifting register unit comprises an initial module, a first capacitance module, a first node control module, an electric potential control module, a second capacitance module, a second node control module, an output module and a third node control module, wherein the initial module is used for controlling a first node to connect with or disconnect from an initial voltage input end under the control of the input end of a first clock signal; the first end of the first capacitance module is connected with the input end of a second clock signal and the second end of the first capacitance module is connected with the first node; the first node control module is used for controlling the first node to connect with or disconnect from a first electrical level input end under the control of a third node; and the electric potential control module is used for controlling a second node to connect with or disconnect from a second electrical level input end under the control of the first node. Normal transmission of signals under narrow pulse width can be 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] In the field of display, in order to continuously improve display images and enhance user experience, high-definition and high-ppi (pixel perinch, number of pixels per inch) display has become a research hotspot. However, as the number of pixels increases, the number of lines to be scanned by the gate drive circuit including the multi-stage shift register unit increases within one frame display time, and the average pulse width of each line of the gate drive signal is continuously narrowed. The requirements for the drive capability of bit registers are constantly increasing. Contents of the invention [0003] The main purpose of the present invention is to provide a shift register unit, a driving method, a gate drive circuit and a display device, so as to...
