  • Patent number: 11362301
    Abstract: A display panel and a display device are provided. The display panel includes a display region, a hole-digging region, and a boundary region disposed between the display region and the hole-digging region. The display panel also includes an array substrate and a light-emitting function layer. The array substrate includes a dam structure disposed between the display region and the boundary region. The light-emitting function layer covers the array substrate, and includes a first light-emitting component disposed over the display region and a second light-emitting component disposed over the boundary region. The array substrate further includes a base substrate and a driving device layer, and the driving device layer includes a first thin-film transistor device layer and a boundary driving circuit layer.

  • Patent number: 11088350
    Abstract: A display device and a method for manufacturing the same are provided. The display device has a display area and a non-display area and includes: a substrate; a driving circuit layer including pins located in the non-display area; a light-emitting device layer; a thin film encapsulation layer including a first inorganic encapsulation layer; a touch sensing unit including a touch insulation layer; and a protective layer. Projections of the first inorganic encapsulation layer and the protective layer onto the substrate have coincident edges and do not cover the pins; or projections of the first inorganic encapsulation layer and the touch insulation layer onto the substrate have same outlines and do not overlap with the pins.
