Patent ID: 8059780

Claim:
A shift register circuit comprising: a shift register, having a start pulse signal input terminal and a start pulse signal output terminal; a first switching circuit, comprising a first input switch unit and a second output switch unit, wherein the first input switch unit is electrically coupled to the start pulse signal input terminal, and the second output switch unit is electrically coupled to the start pulse signal output terminal; and a second switching circuit, comprising a second input switch unit and a first output switch unit, wherein the second input switch unit is electrically coupled to the start pulse signal input terminal, and the first output switch unit is electrically coupled to the start pulse signal output terminal; wherein on-off states of both the first input switch unit and the first output switch unit are opposite to on-off states of both the second input switch unit and the second output switch unit; and wherein: the first input switch unit and the first output switch unit are subject to the control of two first control signals, and the second input switch unit and the second output switch unit are subject to the control of two second control signals; when the first input switch unit and the first output switch unit are the on-state, the two first control signals are phase-inverted, while the two second control signals are fixed to a same constant voltage level; and when the second input switch unit and the second output switch unit are the on-state, the two second control signals are phase-inverted, while the two first control signals are fixed to a same constant voltage level.
