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: 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: The present disclosure relates to the field of display technologies, and provides an OLED light emitting module, a manufacturing method thereof, and a display device. The OLED light emitting module includes a base substrate, an OLED light emitting device on the base substrate, and a metal stack on the OLED light emitting device. The metal stack includes a first metal layer, a second metal layer and a third metal layer arranged in stack. The second metal layer includes an invar alloy. The first metal layer and the third metal layer include a metal material different from the invar alloy.

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: A film forming apparatus, including a base having a first chamber, an upper cover for at least covering an opening of the first chamber, and a first seal ring between the upper cover and the base, wherein the upper cover has an inclined slope, an orthographic projection of the slope in a plane where a bottom surface of the base is located overlaps with a region surrounded by an orthographic projection of the first seal ring in the plane where the bottom surface of the base is located, the orthographic projection of the slope is located is outside an orthogonal projection of the first chamber, and a portion of the slope close to the first chamber is away from the bottom surface of the base with respect to a portion of the slope away from the first chamber.
