Problems solved by technology

[0004] The inventor found that the GOA circuit in the related art includes a pull-up node, a pull-down node, and a signal output terminal. In order to avoid noise from the GOA circuit, it is necessary to provide a high-level signal to some transistors to control the pull-up through the signal of the pull-down node. The signal at the node and the signal output terminal is low lev

Abstract

The invention discloses a shift register and a driving method thereof, and a gate driving circuit. The shift register comprises a pull-up sub-circuit which is used for providing a signal of a forwardscanning signal end for a pull-up node under the control of a first input end, and is also used for providing a signal of a reverse scanning signal end for the pull-up node under the control of a second input end; an output sub-circuit, used for providing a signal of a clock signal end for the signal output end under the control of the pull-up node; a pull-down sub-circuit, used for providing a signal of a first power supply end for the pull-down node under the control of the first control end or the second control end, and providing a signal of a second power supply end for the pull-down nodeunder the control of the first input end, the second input end and the pull-up node; and a noise reduction sub-circuit, used for providing signals of the second power supply end for the pull-up nodeand the signal output end under the control of the pull-down node. According to the technical scheme provided by the invention, the working stability, the use reliability and the display effect of thedisplay panel are improved.

Description

technical field [0001] This article relates to the field of display technology, in particular to a shift register, a driving method thereof, and a gate driving circuit. Background technique [0002] In recent years, flat panel displays, such as Thin Film Transistor-Liquid Crystal Display (TFT-LCD) and Active Matrix Organic Light Emitting Diode (AMOLED), have been It is widely used in electronic products such as TVs and mobile phones because of its advantages of thinness and low power consumption. [0003] With the development of display technologies, display panels with high resolution and narrow borders have become a development trend, for which Gate Driver on Array (GOA for short) circuits appear. GOA technology directly integrates the gate drive circuit of the display panel on the array substrate to replace the external drive chip, which has the advantages of low cost, less process and high production capacity. [0004] The inventor found that the GOA circuit in the rel...
