Problems solved by technology

[0003] At present, thin-film encapsulation technology is generally used to block water and oxygen during the production of organic light-emitting display panels, but water and oxygen may still penetrate from the gap between the encapsulation layer and the light-emitting layer and the array substrate, corroding the light-emitting materials and the array substrate. Cathode materials, reducing the efficiency and lifetime of OLED devices

Embodiment Construction

[0052] 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.

[0053] In OLED devices, the light-emitting materials in the organic light-emitting structure array are usually polymers or small organic molecules, and the cathode materials are usually active metals with low work functions such as magnesium-aluminum, etc. These light-emitting materials and cathode materials are very sensitive to water vapor and oxygen. The penetration of water / oxygen will greatly reduce the lifespan of OLED devices. In order to meet the requirements of commercialization for the lifespan and stabil...

Abstract

The invention discloses an organic light-emitting display panel, a preparation method and a display device, wherein the organic light-emitting display panel comprises a display area and a non-displayarea surrounding the display area, the display panel comprises a substrate, an organic light-emitting structure array layer, a plurality of film layers, and a hydrophobic structure; the organic light-emitting structure array layer is located in the display area of the substrate; the plurality of film layers are located on one side of the substrate facing the organic light-emitting structure arraylayer and extend to the non-display area; and the hydrophobic structure is located between any two adjacent film layers of the plurality of film layers in the non-display area. According to the organic light-emitting display panel, the preparation method and the display device provided by the embodiment of the invention, water and oxygen can be effectively prevented from seeping into the gaps of the film layers in the non-display area, the light-emitting material and the cathode material in the organic light-emitting display panel are prevented from being corroded, effective blocking of waterand oxygen is realized, and the packaging effect of the organic light-emitting display panel is guaranteed.

Description

technical field [0001] Embodiments of the present invention relate to display technology, and in particular to an organic light emitting display panel, a manufacturing method and a display device. Background technique [0002] Organic Light Emitting Display (OLED) has self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, wide viewing angle, wide operating temperature range, and can realize flexible display and large area With many advantages such as full-color display, it is recognized by the industry as a display device with the most potential for development. [0003] At present, thin-film encapsulation technology is generally used to block water and oxygen during the production of organic light-emitting display panels, but water and oxygen may still penetrate from the gap between the encapsulation layer and the light-emitting layer and the array substrate, corroding the light-emitting materials and the array s...
