Patent ID: 10573245

Abstract:
A shift register unit and a driving method thereof, shift register and display device. The shift register unit including an input circuit (P1), a pull-down control circuit (P2), a pull-up control circuit (P3), a pull-up circuit (P4) and a pull-down circuit (P5); wherein the input circuit (P1) is connected to a first trigger signal end (STU), a first clock signal end (CLK1), a power level end (VGL) and a pull-up control node (Q), and is for utilizing a bootstrap effect to transfer a signal of the first trigger signal end (STU) to the pull-up control node (Q) without a threshold voltage loss. The shift register unit is for use in a display device, and resolves the problem of a display device having a non-uniform display, resulting in a poor displaying effect of a display device.
