Abstract
A shift register circuit includes plural shift register stages for providing plural gate signals. The Nth shift register stage of the shift register stages includes an input unit, a pull-up unit and a pull-down unit. The input unit is put in use for outputting an Nth driving control voltage according to an (N−1)th gate signal and an (N−2)th driving control voltage which are generated respectively by the (N−1) th shift register stage and the (N−2) th shift register stage of the shift register stages. The pull-up unit pulls up an Nth gate signal according to the Nth driving control voltage and a system clock. The pull-down unit pulls down the Nth gate signal and the Nth driving control voltage according to an (N+2)th gate signal generated by the (N+2)th shift register stage of the shift register stages.
