Shift register unit and driving method therefor, shift register, display device
There is provided a shift register unit and driving method for the shift register unit, a shift register and a display device. The shift register unit comprises a first capacitor (C1), an input buffering module (31), a pulling-up module (32), a reset control module (33), a pulling-down module (34) and a pulling-down enhancement module (35); the pulling-down module (34) is configured to reduce the level at the signal output terminal (OUTPUT) and discharge the first capacitor (C1) during a first noise-removal phase; the pulling-down enhancement module (35) is configured to control, in cooperation with the pulling-down module (34), to continuously reduce the level at the signal output terminal (OUTPUT) and continuously discharge the first capacitor (C1) during a second noise-removal phase. Noise in the output signals of the shift register can be reduced and reliability of the shift register can be improved.
