Abstract

The invention discloses a shift registering unit, a shift register, a driving method of the shift register and a display device. The shift registering unit comprises a first transistor, a second transistor, a third transistor, a fourth transistor, a fifth transistor, a sixth transistor, a seventh transistor, a first capacitor, a second capacitor, a third capacitor, an input signal end, a first clock signal end, a second clock signal end, a first voltage signal end, a second voltage signal end and a first output end. According to the invention, shift output of grid signals can be achieved via quite few transistors, power consumption of the shift register is reduced; a circuit failure caused by potential competence of nodes and threshold value drifting of the transistors can be avoided; and stability of circuit operation is enhanced.

Description

technical field [0001] The present application relates to the field of display technology, in particular to a shift register unit, a shift register and a driving method thereof, and a display device. Background technique [0002] In a conventional design of a display panel, a pixel array, a plurality of gate lines, and a data line insulated and intersecting with the plurality of gate lines may be arranged on the display panel. In addition, a gate driving circuit may also be arranged on the display panel. After the gate drive circuit shifts the input single pulse signal step by step, each gate line is turned on in turn to realize the row scanning of the pixel array on the display panel. [0003] figure 1 A schematic structural diagram of a driving unit of an existing gate driving circuit is shown, and the driving unit is used to drive a gate line. like figure 1 As shown, the driving unit 100 includes a shift register unit 11 and an inverter 12 . The shift register unit 1...
