Abstract: A display panel includes: a substrate; a display function layer located on the substrate, where the display function layer includes multiple light-emitting elements; and a light-shielding layer arranged above an emission surface of the display function layer. The display panel includes an active area and a non-active area. The light-shielding layer in the active area is thinner than the light-shielding layer in the non-active area. The light-shielding layer is provided with multiple openings. In a thickness direction of the display panel, the openings expose the light-emitting elements. Groove structures are formed in the light-shielding layer in at least part of the non-active area.

Abstract: A display panel and a display device are provided. A part of a border area of the display panel surrounds an active area of the display panel. The border area includes a fan-out area located on a side of the active area and a bonding area located on a side of the fan-out area away from the active area. The display panel includes a substrate, a first metal layer arranged on a side of the substrate and including a signal wire, an organic layer arranged on a side of the first metal layer away from the substrate and including an opening defined in the border area, and a second metal layer including a shielding electrode arranged on a first section. The signal wire includes the first section located in the opening.

Abstract: An array substrate and a display device are provided. The array substrate includes a substrate, a first metal layer, a second metal layer and a semiconductor layer. The first metal layer is located on a side of the semiconductor layer away from the substrate. The first metal layer includes first wiring. The semiconductor layer includes second wiring. The second metal layer includes jumper wiring. The array substrate includes an active area and a non-active area. In the non-active area, the second wiring includes a first segment and a second segment located on both sides of the first wiring respectively in a first direction, and connected through the jumper wiring. In a direction perpendicular to a plane in which the array substrate extends, the jumper wiring at least partially overlaps the second wiring.

Abstract: Provided a touch display panel includes a signal transmission layer, an insulation layer, and a touch layer disposed in stack. A surface of the signal transmission layer is provided with first concave-convex structure. The insulation layer covers the first concave-convex structure, and a surface thereof is provided with a second concave-convex structure at least partially overlapping the first concave-convex structure in a light exit direction. The second concave-convex structure includes a second convex portion, a second concave portion, and a second connecting portion, thickness of the second connecting portion smaller than either thickness of the second convex portion or thickness of the second concave portion. A connection via hole is further provided, penetrates at least the second connecting portion, exposes part of the signal transmission layer, and the touch layer electrically connected to the signal transmission layer through the connection via hole.
