ABSTRACT:
A shift register includes a plurality of stages, each of the stages generate an output signal, in sequence. Each of the shift register includes a present stage and a first capacitor. The present stage outputs an output signal based on one of a scan start signal and a carry signal of the previous stage. The first capacitor reduces a ripple component of the carry signal of the present stage which activates the next stage. Therefore, a carry signal having a reduced ripple component is supplied to the next stage, so that a transient current is intercepted at a transistor receiving the carry signal, which is arranged in the next stage, thus ensuring reliability of the shift register.
