Abstract

A display device according to the present disclosure comprises a substrate including a display area and a non-display area, pixel circuits each including at least one n-type transistor and at least one p-type transistor and arranged in the display area, and a gate driving circuit included in the non-display area and outputting a first scan signal for applying a data voltage to driving transistors of the pixel circuits for an initialization time and a second scan signal that represents a same logic voltage as the first scan signal for the initialization time and represents a logic voltage reverse to the first scan signal for a sampling time. A first scan signal generator and a second scan signal generator are integrated using nodes Q / QB of a logic circuit to reduce a bezel size.

Description

technical field [0001] The present disclosure relates to a gate drive circuit and a display device using the gate drive circuit, in particular, to a first scan signal generator and a second scan signal generator integrated by using a node Q / QB of a logic circuit A gate drive circuit for a display device with a narrow bezel and a display device using the gate drive circuit. Background technique [0002] Currently, various display devices are being developed and have entered the market. For example, there are devices such as liquid crystal display (LCD) devices, field emission display (FED) devices, electrophoretic display (EPD) devices, electrowetting display (EWD) devices, organic light emitting display (OLED) devices, and quantum dot display (QD) devices. display device. [0003] In the development of various technologies for realizing mass production of display devices and various products, technological enhancement is realized based on technologies for realizing designs...
