Abstract: A gate driving circuit and a display device are disclosed. The gate driving circuit includes a shift register including a plurality of stages. Among the stages, an Nth stage includes a first transistor charging a Q node and a junction stress control circuit. A pull-up transistor using the Q node as a gate input controls an output signal of a stage output terminal. The junction stress control circuit includes a first, second, and third control transistors. The first control transistor, the second control transistor, the third control transistor, and the first transistor are connected to each other through a common node. The second control transistor adjusts junction stresses for the first control transistor and the first transistor by controlling a voltage of the common node. When the second control transistor is turned off, the third control transistor discharges the voltage of the common node.

Abstract: A display panel and a method of driving the same are disclosed. The display panel includes a shift register with a plurality of stages configured to shift and to output a scan pulse for a plurality of scan lines. Each stage includes a pull-up transistor and a pull-down transistor coupled in series and defining an output node therebetween, a driver with a first node coupled to a gate electrode of the pull-up transistor and a second node coupled to a gate electrode of the pull-down transistor; and a node controller coupled to the first node, the second node, and the output node. In each stage, the node controller is configured to selectively apply a reference voltage at the first node and the second node in response to a control signal.

Abstract: A touch sensor integrated display device includes a plurality of common electrode blocks serving as touch-sensing regions and/or touch-driving regions. Conductive lines connected to the common electrode blocks are placed under the common electrode blocks and the pixel electrodes of the pixels, and they are routed across the active area, directly toward an inactive area where drive-integrated circuits are located. The conductive lines are positioned under one or more planarization layers, and are connected to the corresponding common electrode blocks via one or more contact holes.
Abstract translation: 触摸传感器集成显示装置包括用作触摸感测区域和/或触摸驱动区域的多个公共电极块。 连接到公共电极块的导电线被放置在公共电极块和像素的像素电极之下，并且它们被直接穿过有源区域路由到驱动集成电路所在的无效区域。 导线位于一个或多个平坦化层之下，并且经由一个或多个接触孔连接到相应的公共电极块。

Abstract: A touch display device, a display panel, and a gate driving circuit are disclosed. A touch display device comprises a display panel having subpixels, a gate driving circuit including gate stages for applying a scan signal to the display panel through gate lines and dummy stages selectively disposed between the gate stages, and a touch driving circuit applying a touch driving signal to the display panel through touch lines and receiving a touch sensing signal generated by the display panel, wherein the dummy stages are divided into two or more dummy stage groups, and wherein a group control signal line for applying a group control signal based on dummy stage group and an individual control signal line for applying an individual control signal to each dummy stage included in the dummy stage group are disposed along a bezel area.
