ABSTRACT:
A shift register includes a plurality of stages each generating an output signal in sequence and including a buffering section, a driving section, a first charging section, and a charging control section. The buffering section receives one of a scan start signal and an output signal of a previous stage so that the driving section generates the output signal of a present stage. The first charging section includes a first terminal electrically connected to the driving section and a second terminal electrically connected to a first source voltage. The charging control section applies the output signal of a next stage to the first charging section. Therefore, a gradual failure of TFT is reduced.
