Title: SHIFT REGISTER UNIT, GATE DRIVE CIRCUIT, DISPLAY DEVICE, AND EXCEPTION HANDLING METHOD
Abstract:
A shift register unit, a gate drive circuit comprising the shift register unit, a display device, and an exception handling method applied to the shift register unit. The shift register unit comprises a pull-up node control circuit (101), an output circuit (102), a pull-down node control circuit (103), and an exception control circuit (104). The exception control circuit (104) is connected between an exception indication signal end (EN), an output end (OUTPUT), a pull-up node (PU), and a pull-down node (PD), and is configured to make the output end (OUTPUT) output high level and reset the pull-up node (PU) and the pull-down node (PD) under the control of an exception indication signal received by the exception indication signal end (EN) at the moment an exception occurs.
