  • Patent number: 12224289
    Abstract: An array substrate includes gate lines, data lines and an insulating layer. The data lines all extend in a first direction, and the gate lines all extend in a second direction, the first direction intersecting the second direction. A data line includes first line segments and second line segments that all extend in the first direction and are arranged alternately. The second line segments are disposed at a side of the gate lines proximate to the base, and the first line segments are disposed at a side of the gate lines away from the base. There is no overlap among orthographic projections of the first line segments on the base and orthographic projections of the gate lines on the base. The insulating layer includes first vias. In the first direction, any two adjacent first line segments are electrically connected to a second fine segment through at least two first vias.

  • Publication number: 20250048871
    Abstract: A display substrate and a display device are provided. The display substrate includes a base substrate, organic light-emitting elements, a data line, and an electrode line. The organic light-emitting element includes a first electrode, a light-emitting layer and a second electrode sequentially stacked; the data line is located between the base substrate and the organic light-emitting element; the electrode line is on the same layer as the data line and located in a region outside a light-emitting region of the organic light-emitting element. The display substrate further includes at least one connection portion, which is in the region outside the light-emitting region and is configured to connect the electrode line and the first electrode, the connection portion is spaced apart from the second electrode, and the light-emitting layer covers the second electrode and the at least one connection portion.
