<p>The present disclosure discloses a shift register unit and a driving method thereof, a shift register and a display apparatus. The shift register unit includes a carry signal output terminal; a driving signal output terminal; a staged output module connected to the pulling-up node, the pulling-down node, the carry signal output terminal and the driving signal output terminal, respectively, for outputting a carry signal and a driving signal in stages so that the driving signal maintains a high level in the evaluating phase and a low level in the resetting phase; a pulling-up node level maintaining module for, in the evaluating phase, maintaining the level at the pulling-up node at a high level via the first output control module so that the driving signal maintains the high level. The present disclosure removes the effect of the leakage current of the depletion type TFT on the shift register by using staged output and maintaining the pulling-up node level, which increases stability and reliability thereof and decreases power consumption.</p> |
