Title:
OLED ENCAPSULATION STRUCTURE, OLED ENCAPSULATION METHOD AND DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2018/192169
Kind Code:
A1
Abstract:
Disclosed are an OLED encapsulation structure (200, 400, 600), an OLED encapsulation method (300, 500, 700) and a display panel, wherein the OLED encapsulation structure (200, 400, 600) comprises: a substrate (210, 410, 610), an OLED structure to be encapsulated being arranged on a surface of the substrate (210, 410, 610); an inorganic covering layer (220, 420, 620) arranged on the substrate (210, 410, 610) and the OLED structure, such that an edge portion of the surface is covered by the inorganic covering layer (220, 420, 620); and a blocking layer (230, 430, 630) arranged on the inorganic covering layer (220, 420, 620) via an adhesion structure (240, 440, 640). The adhesion structure (240, 440, 640) comprises at least one protruding strip located on a part of the edge portion, the protruding strip is located between the inorganic covering layer (220, 420, 620) and the blocking layer (230, 430, 630) and/or located between the substrate (210, 410, 610) and the blocking layer (230, 430, 630) to form an airtight space between the inorganic covering layer (220, 420, 620) and the blocking layer (230, 430, 630) and/or an airtight space between the substrate (210, 410, 610) and the blocking layer (230, 430, 630).
