Abstract: A packaging cover plate and a manufacturing method thereof, a display panel, and a display device are provided. The packaging cover plate includes: a packaging sheet including a first surface and a second surface opposite to each other. The first surface of the packaging sheet is provided with at least one first channel, the second surface of the packaging sheet is provided with at least one second channel, and an extension direction of the first channel is parallel to an extension direction of the second channel. An orthographic projection of the at least one first channel on the packaging sheet and an orthographic projection of the at least one second channel on the packaging sheet are arranged alternately, and a sum of a depth of the first channel and a depth of the second channel is not less than a thickness of the packaging sheet.

Abstract: An organic light-emitting display panel, a method of forming the same and a display device are provided. The method of forming an organic light-emitting display panel includes: providing a base substrate; forming an auxiliary cathode at a side of the base substrate and forming a pixel defining layer at a side of the auxiliary cathode away from the base substrate; filling a negative thermal expandable ball into the groove; forming a light-emitting layer at the side of the base substrate; performing a heating treatment and a vibrating treatment on the base substrate with the light-emitting layer; and forming a cathode layer at a side of the light-emitting layer away from the base substrate.

Abstract: A packaging cover plate and a manufacturing method thereof, a display panel, and a display device are provided. The packaging cover plate includes: a packaging sheet (00) including a first surface and a second surface opposite to each other. The first surface of the packaging sheet (00) is provided with at least one first channel (001), the second surface of the packaging sheet (00) is provided with at least one second channel (002), and an extension direction of the first channel (001) is parallel to an extension direction of the second channel (002). An orthographic projection of the at least one first channel (001) on the packaging sheet (00) and an orthographic projection of the at least one second channel (002) on the packaging sheet (00) are arranged alternately, and an sum of a depth (h1) of the first channel (001) and a depth (h2) of the second channel (002) is not less than a thickness (H) of the packaging sheet (00).

Abstract: Provided are an encapsulating thin film, a production method thereof, and a method for encapsulating a display panel. The encapsulating thin film has: a protective film; a plurality of discrete metal film units on the protective film; an adhesive layer on each of the metal film units; and optionally a release layer. This encapsulating thin film may be used to encapsulate a plurality of display panels simultaneously.

Abstract: The present disclosure discloses a film carrier, a film application apparatus, a film application, and a film to be applied used in a display panel. The film carrier comprises: a main body part and an attraction member. The main body part has a supporting surface and is configured to be rotatable to drive the supporting surface to swing about an axial direction of the main body part. The supporting surface has a curved projection in a plane perpendicular to the axial direction. The attraction member is disposed on the main body part for attracting the film to be applied on the supporting surface.
