Abstract

The invention discloses an intraplate gate type gate driver and a display device. 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.

Description

technical field [0001] The present disclosure relates to a display device, and more particularly, to a gate driver and a display device including the gate driver. Although the present disclosure is applicable to a wide range of applications, it is particularly suitable for gate drivers having reduced bezel size by reducing the number of thin film transistors. Background technique [0002] With the development of various portable electronic devices such as mobile terminals and notebook computers, demand for flat panel display devices employed in such devices is increasing. [0003] Research is being conducted on flat panel display devices including liquid crystal display (LCD) devices, plasma display panel (PDP) devices, field emission display (FED) devices, and organic light emitting diode display (OLED) devices. [0004] Among these flat panel display devices, LCD devices have more applications because they can be mass-produced, can be easily driven, and can realize high i...
