Shifting register, gate drive circuit and display panel

Abstract

The embodiment of the invention discloses a shift register, a gate drive circuit and a display panel. The shift register comprises a node adjusting module, a following control module and a pull-up control module, the node adjusting module adjusts an output first node signal, a second node signal and a third node signal according to the trigger signal and the first clock signal; the pull-up controlmodule controls whether a shift signal output by the shift register follows a first power supply signal transmitted to the pull-up control module or not according to the first node signal and the second node signal; the following control module controls whether a shifting signal output by the shifting register follows a second clock signal transmitted to the following control module or not according to a third node signal, and the shifting register comprises seven switches or eight switches. By means of the technical scheme, seven switches or eight switches are used for achieving the shiftingfunction of the shifting register, meanwhile, the number of the switches in the shifting register is reduced, and implementation of a narrow frame of the display panel is facilitated.

Description

technical field [0001] The embodiments of the present invention relate to the field of display technology, and in particular to a shift register, a gate driving circuit and a display panel. Background technique [0002] With the development of organic light-emitting display technology, organic light-emitting display panels are widely used in mobile phones, computers, vehicles and wearable devices due to their advantages such as wide color gamut, high contrast, healthy eye protection, and fast response. For devices such as mobile phones and smart watches, narrow bezels have become a mainstream development trend in the display field. [0003] The non-display area of ​​the display panel is provided with a gate drive circuit, and the gate drive circuit includes a plurality of shift registers, and the number of transistors in the shift register directly affects the area of ​​the frame of the display panel. At present, the shift register in the gate drive circuit needs at least n...

AI Technical Summary

Problems solved by technology

At present, the shift register in the gate drive circuit needs at least nine transistors to realize the step-by-step shift function. The large number of transistors is not conducive to the realization of the narrow frame of the display panel.
