Embodiment Construction

[0035] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0036] figure 1 is a schematic diagram of a display panel, figure 2 yes figure 1 A schematic cross-sectional view of the middle display panel along the section line A1-A2. refer to figure 1 and figure 2 , the display panel includes a substrate 10, an organic light-emitting structure 20, and a thin-film encapsulation layer 30. In order to avoid overflow of the organic layer 32 of the thin-film encapsulation layer 30, a circle of retaining walls 40 is generally provided in the non-display area 12 of the substr...

Abstract

The embodiment of the invention discloses a display panel, a display device and a display panel manufacturing method. The display panel comprises a substrate, an organic light-emitting structure, a film packaging layer and a polymerization inhibiting substance, wherein the substrate includes a display area and a non-display area; the organic light-emitting structure is arranged in the display areaof the substrate; the film packaging layer covers the organic light-emitting structure; the film packaging layer includes inorganic layers and an organic layer which are arranged at intervals; the polymerization inhibiting substance is arranged in the non-display area of the substrate and surrounds the display area; and the polymerization inhibiting substance is arranged in the same layer as theorganic layer and used for preventing the polymerization reaction of organic monomers contacted with the polymerization inhibiting substance in the process of forming the organic layer and confining the organic layer in an area surrounded by the polymerization inhibiting substance. The embodiment of the invention provides a method for preventing overflow of the organic monomers without setting a retaining wall, and improves the bending characteristics of the display panel.

Description

technical field [0001] Embodiments of the present invention relate to organic light-emitting display technologies, and in particular, to a display panel, a display device, and a method for manufacturing a display panel. Background technique [0002] For Organic Light Emitting Diode (OLED) display technology, since OLED light emitting materials and electrodes are very sensitive to water vapor and oxygen, packaging is required. Common packaging methods are divided into glass cover packaging and film packaging. The common thin film encapsulation structure is generally a combined laminated structure of organic layers and inorganic layers. [0003] Usually, in order to ensure the flatness of the organic film layer and the requirements of the organic film layer spraying equipment, organic monomers with lower viscosity are often used. In order to prevent the overflow of organic monomers, a retaining wall structure is designed outside the display area of ​​the display panel. Howe...
