A shift register unit and a drive method therefor, and a gate drive circuit and a display apparatus. In the shift register unit, an input module (1) is configured to output a pull-up control signal to a pull-up module (4) according to a first DC voltage signal (VDF) and a turn-on signal (Input); the pull-up module (4) is configured to output a shift signal (Gn) via a first output end (out1) and to output a turn-on signal (Input) for the next stage of the shift register unit via a second output end (out2) according to a second DC voltage signal (VDD) and a clock signal (CLK); a pull-down control module (2) is configured to output a pull-down control signal to a pull-down module (3) according to the second DC voltage signal (VDD), a third DC voltage signal (VSS) and the clock signal (CLK); the pull-down module (3) is configured to output, to the pull-up module (4), a pull-down signal for the first output end (out1), the second output end (out2) and a pull-up point (PU); and a reset module (5) is configured to reset the pull-up module (4) according to a fourth DC voltage signal (VDB) and a reset signal (Reset). Using a DC voltage as the input signal for the pull-up module (4) and the pull-down control module (2), the present invention is stable and consumes little power. |
