A kind of shift register and its driving method, gate driving circuit

Abstract

A shift register and its driving method, and a gate drive circuit, wherein the shift register includes: a first input sub-circuit for providing a signal of a first power supply terminal to a first pull-up node under the control of a signal input terminal; An output sub-circuit is used to provide the signal of the first clock signal terminal to the first output terminal under the control of the first pull-up node; the second input sub-circuit is used to supply the signal of the second upper clock signal terminal to the second The pull node provides the signal of the first clock signal terminal; the second output subcircuit is used to provide the first output terminal and the second output terminal under the control of the second pull-up node, the first clock signal terminal and the second clock signal terminal. The signal of the second clock signal terminal; the node control subcircuit is used to provide the signal of the third power supply terminal to the first pull-up node and the first output terminal under the control of the second power supply terminal, the first pull-up node and the second pull-up node . The technical solution provided by the present application can realize the driving of the transflective display panel.

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] With the continuous development of display technology, transflective liquid crystal display panels have been widely used due to their advantages of low power consumption and strong environmental adaptability. The transflective liquid crystal display panel includes: an array substrate gate driver (Gate Driver on Array, referred to as GOA) circuit for realizing display, a plurality of scan lines and a plurality of pixels, wherein the GOA circuit includes a plurality of shift registers , each pixel is driven by three scanning lines, and includes two sub-pixels, each sub-pixel is provided with a double-gate thin film transistor, and the driving signal of each scanning line is provided by a shift register. [0003] The inventors found that under odd-even driving conditions, pixels in...

Problems solved by technology

figure 1 The timing diagram for the drive signal of the scan line in the related art, such as figure 1 As shown, the scanning line Gate3 needs to complete two outputs before it can be driven. In the related art, the output of the shift register is relatively single, which cannot realize two pulse outputs, and thus cannot realize the driving of the transflective display panel.
