    Abstract: Agate 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: An array substrate includes: a display area; a non-display area outside of the display area; a gate-in-panel (GIP) circuit in the non-display area; a plurality of clock signal lines in the non-display area and configured to transfer signals to the GIP circuit; and connection lines in the non-display area and configured to connect the plurality of clock signal lines to the GIP circuit. Each of the plurality of clock signal lines is a ring shaped line.

    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.
