Abstract
A shift register having individual driving nodes is disclosed. The shift register includes a first clock pull-down module, a second clock pull-down module, a key pull-down module, a self feedback module, and a driving output unit. The first clock pull-down module is used to pull-down the potential of a gate line to a low voltage when the first clock signal is in a high voltage level. The second clock signal pull-down module pulls down the potential of the gate line to the low voltage when the second clock signal is in a high voltage level. The key pull-down module rapidly pulls down the potential of the gate line to the low voltage level after the gate line outputs an output signal. The self feedback module is used to output a driving signal to the key pull-down module. The driving signal output unit outputs a next stage driving signal which is irrelative to the operation of the previous stage shift register.
