SHIFT REGISTER, GATE DRIVING CIRCUIT AND REPAIRING METHOD THEREFOR, AND DISPLAY DEVICE

摘要

A shift register (10), a gate driving circuit and a repairing method therefor, and a display device. The shift register (10) comprises a shift register module (21), a repairing module (22), a first connectable link (L1) arranged between the exciting signal input terminal (P100) of the shift register (10) and the exciting signal input terminals (P210, P220) of these two modules, and a second connectable link (L2) arranged between the output terminal (P101) of the shift register (10) and the output terminals (P211, P221) of these two modules; the shift register module (21) is configured to output a clock signal inputted at the first clock signal input terminal via its own output terminal (211) according to an exciting signal received at its own exciting signal input terminal (P210); the repairing module (22) is configured to output an exciting signal received at its own exciting signal input terminal (P220) after delaying the same by a half clock period via its own output terminal (P221) in a case in which a malfunction occurs in the shift register module (21). Since the shift register module (21) is replaced by the repairing module (22) in a case in which the shift register module (21) has a malfunction, the subsequent shift registers can operate properly.
