Abstract: 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.

Abstract: Discussed are a built-in gate driver capable of improving output characteristics of the gate driver by reducing load of clock lines and a display device using the same. The built-in gate driver can include a shift register, a first clock group and a second clock group located in a non-display region of a display panel. The shift register includes a plurality of stages for individually driving gate lines of a display region. The first clock group includes clock lines arranged at a first side of the shift register. The second clock group includes clock lines arranged at a second side of the shift register. Each of the clock lines includes a main line and a branch line branched from the main line and connected to a corresponding stage. A branch line belonging to a corresponding clock group of any one of the first and second clock groups does not overlap a main line belonging to the other clock group.

Abstract: A shift register is provided in which leakage of charges from a voltage at a set node is prevented to stabilize an output from a stage. The shift register includes stages for sequentially outputting scan pulses. An nth one of the stages includes a node controller for controlling voltages at nodes, and an output unit for outputting any one of a corresponding one of the scan pulses and a first discharging voltage according to the voltages at the nodes. The nodes include set and reset nodes. The node controller of the nth stage includes a first switching device controlled by a voltage supplied to the reset node for supplying a second discharging voltage to the set node, and an inverter circuit controlled by a voltage supplied to the set node for supplying any one of a charging voltage and a third discharging voltage to the reset node.
