Problems solved by technology

The thin film encapsulation layer used in thin film encapsulation technology includes at least one inorganic layer. The inorganic layer mainly plays the role of blocking water and oxygen. However, due to the small elastic modulus of the inorganic layer, bending cracks are prone to occur, resulting in encapsulation failure.

Abstract

The invention provides an organic light-emitting display panel and a display device. The organic light-emitting display panel comprises a substrate, an organic light-emitting structure layer, a thin film packaging layer, at least one retaining wall and at least one protective device, wherein the substrate comprises a display area, a non-display area, at least one special-shaped edge located in thenon-display area and at least one special-shaped area corresponding to the at least one special-shaped edge; the special-shaped area is an area in the non-display area adjacent to the special-shapededge on the substrate; the organic light-emitting structure layer is located on one side of the substrate and located in the display area; the thin film packaging layer is located on one side, far away from the substrate, of the organic light-emitting structure layer; the thin-film packaging layer comprises at least one inorganic layer; the inorganic layers in the thin film packaging layer cover the organic light-emitting structure layer in the display area and extend to cover part of the substrate in the non-display area; the at least one retaining wall is located in the non-display area; theinorganic layers cover the at least one retaining wall; and the at least one protective device is located in the special-shaped area and is located on one side, far away from the display area, of theat least one retaining wall. The water and oxygen resistance of the thin film packaging layer can be improved, so that the occurrence of package failure can be prevented.

Description

technical field [0001] Embodiments of the present invention relate to display technology, and in particular to an organic light emitting display panel and a display device. Background technique [0002] The flat panel display device has many advantages such as thin body, power saving, and no radiation, and has been widely used. Existing flat panel display devices mainly include liquid crystal display devices and organic light emitting display devices. The display panel mainly performs the display function in the flat panel display device. [0003] Existing organic light-emitting display panels usually use thin-film packaging technology to package display elements on a substrate. The thin film encapsulation layer used in thin film encapsulation technology includes at least one inorganic layer. The inorganic layer mainly plays the role of blocking water and oxygen. However, due to the small elastic modulus of the inorganic layer, bending cracks are prone to occur, resulting ...
