ABSTRACT:
A shift register circuit having shift registers comprising a first transistor having a gate and a first source/drain for receiving an output signal of a pre-stage shift register, a second transistor having a gate coupled to a second source/drain of the first transistor, a first source/drain coupled to a first clock signal, and a second source/drain coupled to a output, a first pull-down module coupled to the output terminal, for receiving the first clock signal, wherein the output is coupled to a first voltage level when the output signal of pre-stage shift register and the first clock signal are at low voltage level, and a second pull-down module coupled to the output and a second clock signal, wherein the output is coupled to a first voltage level when the output signal of pre-stage shift register and the second clock signal are at low voltage level.
