Abstract
A shift register unit and driving method thereof, a gate driving circuit and a display apparatus are provided. The potential of the pull-up control node is continuously raised by the output signals of multiple stages of shift register circuits. The high level of the pull-up control node can be used to release output noise of the shift register unit, such as to improve the quality of the display apparatus product, and ensures the life and the long time stable operation of the GOA circuit. The shift register unit provided by embodiments of the present disclosure comprises an input module, a pull-up module, a pull-down control module, a pull-up control module and a pull-down module.
