Patent number: 8867697Abstract: 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.Type: GrantFiled: March 18, 2013Date of Patent: October 21, 2014Assignee: LG Display Co., Ltd.Inventors: Yong-Ho Jang, Seung-Chan Choi, Jae-Yong You, Woo-Seok Choi
