Abstract
A shift registers circuit having a series of cascading shift registers comprises a first transistor coupling to an output signal of a pre-stage shift register, a second transistor coupling to the first transistor, an output and a first clock signal, and a pull-down module coupling to the output, output signals of pre-stage and post-stage shift register, a second and a third voltage level. When the second transistor turns on and the first clock signal is at high voltage level, the output is at a first voltage level. When the signal of post-stage shift register is at first voltage level, the output is at the third voltage level.
