    Abstract: The present disclosure provides a gate driving unit, a gate driving method, a gate driving circuitry and a display device. The gate driving unit includes a reverse-phase gate driving signal output end, a normal-phase gate driving signal output end, an input circuitry, an output control circuitry, an input node control circuitry and an output circuitry. The input circuitry is configured to control an input end to be electrically connected to an input node under the control of a first clock signal. The output control circuitry is configured to control a potential at an output node under the control of a potential at the input node and a second clock signal. The input node control circuitry is configured to control the potential at the input node in accordance with the potential at the output node under the control of the second clock signal. The output circuitry is configured to output a reverse-phase gate driving signal and output a normal-phase gate driving signal in accordance with the potential at the output node.

    Abstract: A shift register unit, a driving method, a gate driving circuit and a display device are provided. The shift register unit includes a first gate driving output circuit and a second gate driving output circuit. The first gate driving output circuit is used to output a first gate driving signal through the first gate driving signal output terminal; the second gate driving output circuit is used to generate a second gate driving signal outputted simultaneously with the first gate driving signal based on the first gate driving signal, a first clock signal and a second clock signal. In the present disclosure, the second gate driving output circuit is added, the first gate driving signal, the first clock signal, and the second clock signal are used to generate an inverted second gate driving signal, so that positive and negative switching control signals are generated by one stage of shift register unit.

    Abstract: The present disclosure provides an array substrate, a manufacturing method thereof, and a display device. The array substrate includes: a base substrate, a gate on the base substrate, a conductive wire above the base substrate, a first insulating layer on the gate and the base substrate, and a shielding structure on the base substrate. A first orthographic projection of the conductive wire on the base substrate is spaced apart from a second orthographic projection of the gate on the base substrate. A third orthographic projection of the shielding structure on the base substrate is located between the first orthographic projection and the second orthographic projection. The shielding structure is used to at least partially shield a crosstalk of the conductive wire to the gate.
