Abstract
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 (C), an input buffering module (), a pulling-up module (), a reset control module (), a pulling-down module () and a pulling-down enhancement module (); the pulling-down module () is configured to reduce the level at the signal output terminal (OUTPUT) and discharge the first capacitor (C) during a first noise-removal phase; the pulling-down enhancement module () is configured to control, in cooperation with the pulling-down module (), to continuously reduce the level at the signal output terminal (OUTPUT) and continuously discharge the first capacitor (C) 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.
