    Abstract: A display substrate has sub-pixels. Each column of sub-pixels includes first and second sub-pixels alternately arranged. The display substrate includes a base, a second source-drain metal layer including first and second connection portions, and a first source-drain metal layer including first and second data lines alternately arranged. A pixel driving circuit of each first sub-pixel is connected to a second end of a first connection portion, and a first end there is connected to a corresponding first data line. A pixel driving circuit of each second sub-pixel is connected to a second end of a second connection portion, and a first end thereof is connected to a corresponding second data line. In a same column of sub-pixels, an extension direction of a first line connecting a second end of a first connection portion and a second end of a second connection portion is substantially parallel to a second direction.

    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.
