Abstract

Disclosed are a shift register unit, an operation method for the shift register unit and a shift register comprising the shift register unit. The shift register unit comprises an input module configured to transmit a received input signal to a pull-up node, an output module configured to output a first control signal of a first control signal end to an output end when a pull-up signal at the pull-up node is in effective pull-up level, and a coupling module of which a first end is connected with a second control signal end and a second end is connected with the pull-up node, and configured to control the pull-up signal at the pull-up node according to a second control signal of the second control signal end in a voltage-coupling mode. By further increasing the voltage at the pull-up node during resetting of the output end, the resetting speed of the output end can be increased.

Description

technical field [0001] The present invention relates to the display field, and more particularly relates to a shift register unit, an operation method thereof, and a shift register including the shift register unit. Background technique [0002] Currently, in the circuit structure of the shift register unit, the output end of the shift register unit and the pull-up node are simultaneously reset by using a special output reset transistor and a node reset transistor. Such as figure 1 As shown, the gates of the output reset transistor T4 and the node reset transistor T2 of the shift register unit are connected to the reset input terminal, and the output terminal and the pull-up node are respectively reset under the control of the reset signal output from the reset input terminal. In order to reduce the reset time of the shift register unit, it is necessary to increase the area of ​​the output reset transistor T4 so that the turn-on voltage of the output reset transistor T4 is ...
