Abstract

The present disclosure relates to a shift register, a gate driving circuit and a display apparatus, wherein the shift register outputs an output signal of each stage in a forward direction according to a forward scanning signal and outputs the output signal of each stage in a reverse direction according to a reverse scanning signal, each stage of the shift register includes a forward scanning switch module, a reverse scanning switch module, a pull-up driving module; a pull-up module; a pull-down driving module; a first pull-down module; and a second pull-down module. A bi-directional scanning can be achieved by using the forward scanning switch module and the reverse scanning switch module to control to input different signals to different modules.
