SHIFT REGISTER

摘要

Disclosed is a shift register capable of preventing charges supplied to a Q node to turn on a pull-up transistor for outputting a scan pulse from leaking outwards. The shift register includes a plurality of stages connected to gate lines formed at a panel. Each stage includes a scan signal generator for generating a scan pulse or a turn-off signal, a scan pulse controller for generating a Q-node control signal for generation of the scan pulse, a Q-node adjuster for preventing the Q-node control signal from leaking outwards during supply of the Q-node control signal to a Q-node connected to the scan signal generator, and a turn-off signal controller for transferring a Qb-node control signal for generation of the turn-off signal to the scan signal generator via a Qb-node when no scan pulse is generated from the scan signal generator.
