SHIFT REGISTER UNIT, GATE DRIVING CIRCUIT AND DISPLAY APPARATUS

WIPO Patent Application WO/2023/097477

A1

A shift register unit, a gate driving circuit and a display apparatus, which belong to the technical field of display, and can solve the problem of a leakage current easily being generated due to an unstable threshold voltage of a thin-film transistor in an existing shift register unit. The shift register unit comprises: an input sub-circuit (101), an output sub-circuit (102), at least one pull-down control sub-circuit (103), at least one pull-down sub-circuit (104), at least one first noise reduction sub-circuit (105) and a reverse bias sub-circuit (111), wherein the reverse bias sub-circuit (111) is configured to, in response to the potential of a pull-up node (PU) and by means of a power-supply voltage signal, control a transistor in at least part of a sub-circuit connected to the pull-up node (PU) to be in a reverse bias state, or in response to the potential of a cascade signal end (OUT-C) and by means of a cascade signal, control the transistor in at least part of the sub-circuit connected to the pull-up node (PU) to be in a reverse bias state.
