摘要： A display panel includes a base substrate, an active pattern layer and a first conductive layer. The active pattern layer is disposed on the base substrate, and includes at least one first conductive connection line. The first conductive layer is disposed on a side of the active pattern layer away from the base substrate. The first conductive layer includes at least one connection line extending along a first direction, and a plurality of initialization signal lines arranged along the first direction and extending along a second direction. An end of each initialization signal line is coupled to a connection line in the at least one connection line. The first direction and the second direction intersect. A first conductive connection line in the at least one first conductive connection line is coupled to at least two initialization signal lines that are coupled to a same connection line.

摘要： A display panel having a hole running through the display panel includes: a base substrate; a plurality of light-emitting devices, organic light-emitting functional layers of the light-emitting devices extending to an edge region; an isolation spacer located on the base substrate within the edge region and which are annular structures that surround the hole, the organic light-emitting functional layers are interrupted at the isolation spacer; and an encapsulation layer covering the plurality of light-emitting devices. An inorganic layer in the encapsulation layer extends to the edge region and covers the isolation spacer and the organic light-emitting functional layers. The isolation spacer includes: an inner layer structure and an outer layer structure. The side of the inner layer structure away from the base substrate is provided with a groove-shaped structure, and the outer layer structure includes a through hole.
