  • Publication number: 20230363218
    Abstract: The present disclosure provides a display panel, a manufacturing method thereof, and a display device. The display panel includes: a base substrate including a through hole penetrating through the base substrate, an encapsulation region of the base substrate including an edge surrounding the through hole; and a post spacer arranged between the edge of the encapsulation region surrounding the through hole and the through hole. The post spacer includes a first portion made of metal and a post body made of an insulating material, a distance between the first portion and the base substrate is greater than a distance between the post body and the base substrate, and an area of an orthogonal projection of the first portion onto the base substrate is greater than an area of an orthogonal projection of the post body onto the base substrate.

  • Patent number: 11647646
    Abstract: A method for encapsulating openings in a display area includes: forming an intermediate layer having an isolation hole and an assembly via on a substrate, the isolation hole dividing the intermediate layer into separate display portion and isolation portion and the assembly via being spaced apart from the isolation hole by the isolation portion; forming a groove on a side of the isolation portion facing the display portion and/or on a side of the isolation portion away from the display portion; forming a light emitting layer including a first light emitting portion, a second light emitting portion, a third light emitting portion, and a fourth light emitting portion, wherein the third light emitting portion is separate from at least one of the second light emitting portion and the fourth light emitting portion; and forming an encapsulation layer that covers the light emitting layer and the isolation portion, and is filled in a groove.

  • Patent number: 11443661
    Abstract: A flexible display substrate and a method for manufacturing the same are provided. The method includes: forming a first insulating layer on a flexible base substrate; forming an etching barrier layer on a side of the first insulating layer away from the flexible base substrate; forming a second insulating layer covering the etching barrier layer on the side of the first insulating layer away from the flexible base substrate; and forming a first opening in the first insulating layer and a second opening in the second insulating layer through one patterning process, so that an orthographic projection of the first opening on the flexible base substrate falls within an orthographic projection of the second opening on the flexible base substrate, so as to form a step portion at a connection position where the first opening is connected to the second opening.
