Abstract: In a gate driver, a Q node is shared by two channels to output a scan signal at high level, and a QB node is shared by four channels to output a scan signal at low level. Accordingly, the number of thin-film transistors required to configure four channels of a gate-in-panel (GIP) is reduced, such that the bezel size can be reduced. Further, the gate driver includes a compensation capacitor or a discharge transistor disposed in some of the channels sharing the Q node, such that deviation in output characteristics among the channels sharing the Q node can be reduced.
