SHIFT REGISTER UNIT AND DRIVING METHOD THEREFOR, SHIFT REGISTER, AND DISPLAY DEVICE

摘要

A shift register unit comprises an input module (1), a pull-up module (3), an output control module (2), and an output pull-down module (4). The input module (1) is connected to a signal input end (INPUT), a first clock signal input end (CK), and a low-level signal end (VL). The output control module (2) is connected to a second clock signal input end (CKB) and a high-level signal end (VH). The pull-up module (3) is connected to the high-level signal end (VH). The output pull-down module (4) is connected to the first clock signal input end (CK), the second clock signal input end (CKB), the high-level signal end (VH), and the low-level signal end (VL). The shift register unit can solve the technical problem of the instability of an output signal. Also disclosed are a driving method for the shift register unit, a shift register, and a display device.
