Shift register unit, grid driving circuit, and display device

Abstract

The invention provides a shift register unit, a driving method of the shift register unit, a grid driving circuit and a display device. In the shift register unit, an input module controls the potential of a first node according to an input signal, an output module controls an output signal of an output end according to the potential of the first node and a first clock signal, a pull-down control module controls the potential of a second node according to the potential of the first node and the first clock signal, and keeps the output end in a resetting state before that the input end receives a next input signal, and the resetting module enables a pull-down module to work, according to a resetting signal and the input signal, so as to reset the first node and the output end, and also resets the first node and the output end according to the resetting signal and a second clock signal. The shift register unit has an improved resetting capability, and can avoid resource waste caused by that components in the shift register unit are idle.

Description

technical field [0001] The present disclosure relates to a shift register unit with enhanced reset capability, a driving method thereof, a gate driving circuit including the shift register unit, and a display device. Background technique [0002] With the continuous development of display technology, more and more display devices adopt the GOA (Gate on Array, gate drive on array substrate) technology, that is, the gate drive circuit is formed on the display substrate of the display device through an array process. The use of GOA technology can save costs, and can achieve a symmetrical and beautiful design on both sides of the display panel. At the same time, it can save the bonding area of ​​the gate drive circuit and the wiring space of the fan-out, so that the narrow border design can be realized. In addition, GOA technology can also save the bonding process in the direction of the gate scanning line, thereby improving production capacity and yield. [0003] The gate driv...

AI Technical Summary

Problems solved by technology

[0010] In the above working process, the pull-down module only works during the hold phase and when the potential of the first clock signal terminal is the first potential, and is in an idle state at other times, thus causing a waste of resources

At the same time, the reset capability of such a shift register unit is not high
