SHIFT REGISTER UNIT, DRIVING METHOD, GATE DRIVING CIRCUIT AND DISPLAY DEVICE

摘要

There is provided a shift register unit and driving method thereof, a gate driving circuit and display device. By setting the voltage stabilizing capacitor (C) connected to the pull-up node (P), the shift register unit utilizes the voltage stabilizing capacitor (C2) to stabilize the potential at the pull-up node (P), so as to make the signal output from the shift register unit more stable; and at the same time, uses a very small quantity of transistors and capacitors to compose the shift register unit, so that the wiring area of the gate driving circuit is greatly reduced to provide a technical support for the design of a liquid crystal display device with a narrower frame. In the meantime, since the structure of the gate driving circuit is simplified, the manufacturing process of the gate driving circuit is simplified and the cost for manufacturing is reduced. Further, the shift register unit quickly and effectively pulls down the output signal to the low potential through two pull-down processes, thereby enhancing the pull-down capability of the gate driving circuit.
