Document Type and Number:
WIPO Patent Application WO/2021/218394
Kind Code:
A1
Abstract:
Provided in the present disclosure are a display panel, a fabrication method therefor, and a display apparatus. The display panel comprises openings that pass through the display panel, and comprises: a base substrate; a plurality of light-emitting devices, an organic light-emitting functional layer within the light-emitting devices extending to an edge region; isolation posts, which are located above the base substrate within the edge region and which are annular structures that surround the openings, the organic light-emitting functional layer that extends to the edge region being separated at the location of the isolation posts; and an encapsulation layer, which covers the plurality of light-emitting devices. An inorganic layer in the encapsulation layer extends to the edge region and covers the isolation posts and the organic light-emitting functional layer. Each isolation post comprises: an inner layer structure, and an outer layer structure that covers the inner 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 comprises a through hole that passes through the outer layer structure; the area of the through hole is smaller than the area of the largest opening of the groove-shaped structure, and the orthographic projection of the through hole on the base substrate falls within the range of the orthographic projection of the opening of the groove-shaped structure on the base substrate.
