A gate scanning circuit and a display panel

Abstract

The invention discloses a gate scanning circuit and a display panel. The gate scanning circuit comprises N shift registers arranged sequentially in the first direction, wherein N is a positive integer more than 4; the shift register has a first scanning sequence control end, a second scanning sequence control end, a first input end, a second input end and an output end; the N shift registers are sequentially a first-stage shift register to an N-stage shift register in the first direction; for the n-stage shift register, the first scanning sequence control end is connected with the output end of the n-c-stage shift register, the second scanning sequence control end is connected with the output end of the n+d-stage shift register, the first input end is connected with the output end of the n-a-stage shift register, and the second input end is connected with the output end of the n+b-stage shift register. The technical solution solves the problem of direct current bias of the gate scanning circuit, and improves the stability and the reliability.

Description

technical field [0001] The present invention relates to the technical field of display devices, and more specifically, to a grid scanning circuit and a display panel. Background technique [0002] With the continuous development of science and technology, more and more display devices are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become an indispensable and important display device for people today. tool. [0003] The main component of the display device to realize the display function is the display panel. The display panel needs to use the gate scanning circuit to scan the gate lines one by one according to a preset scanning sequence, so as to drive the pixels of the display panel for image display. The gate scanning circuit is composed of a plurality of cascaded shift registers, and the shift registers are connected to the gate lines in one-to-one correspondence. [0004] When scanning the gate ...

AI Technical Summary

Problems solved by technology

[0005] In the existing gate scanning circuit, whether the forward scanning sequence or the reverse scanning sequence is adopted, a transistor controlling the scanning direction in the shift register will be in a DC bias state. During the long-time display driving process, The DC bias problem will cause the threshold voltage of the transistor to drift, affecting the stability and reliability of the gate scanning circuit
