SHIFT REGISTER, GATE DRIVING CIRCUIT, ARRAY SUBSTRATE AND DISPLAY DEVICE

摘要

Embodiments of the present disclosure disclose a shift register, a gate driving circuit, an array substrate and a display apparatus capable of effectively eliminating a drifting phenomenon of an output signal and increasing an output stability of the shift register. The shift register comprises input terminals of the shift register comprising a start signal input terminal, a first clock signal input terminal and a second clock signal input terminal; a pre-charging circuit which is in response to a start signal and a first clock signal; a first pulling-up circuit which is in response to an enable level of the start signal and an enable level of the first clock signal; a pulling-down circuit which is in response to a disable level of the first clock signal and an enable level of the second clock signal; a second pulling-up circuit; and an output terminal of the shift register.

主权项

1. A shift register, comprising:
input terminals of the shift register, comprising a start signal input terminal, a first clock signal input terminal and a second clock signal input terminal; a pre-charging circuit for outputting a first turn-on voltage and a second turn-on voltage in response to a start signal and a first clock signal; a first pulling-up circuit for outputting a high level in response to an enable level of the start signal and an enable level of the first clock signal under a control of the first turn-on voltage; a pulling-down circuit for outputting a low level in response to a disable level of the start signal, a disable level of the first clock signal and an enable level of a second clock signal under a control of the second turn-on voltage; a second pulling-up circuit for outputting the high level when the second turn-on voltage is at a disable level; and an output terminal of the shift register, connected to an output terminal of the first pulling-up circuit, an output terminal of the pulling-down circuit and an output terminal of the second pulling-up circuit, for outputting a voltage signal.
