Abstract
A shift register includes first and second stages for sequentially outputting scan pulses to drive first and second gate lines. One of the first and second stages includes a pull-up switching device connected to an enabling node of the one of the first and second stages; a first pull-down switching device connected to a first disabling node of the one of the first and second stages; a second pull-down switching device connected to a second disabling node of the one of the first and second stages; and a node controller. The node controller of the first stage controls the logic state of each of the enabling node of the first stage, the first disabling node of the first stage and the first disabling node of the second stage. The node controller of the second stage controls the logic state of each of the enabling node of the second stage, the second disabling node of the second stage and the second disabling node of the first stage.
