Problems solved by technology

[0005] In addition, since the light-emitting materials in OLED displays are organic substances, they are prone to denaturation after being irradiated by ultraviolet rays, and the luminous efficiency and lifespan are reduced, which limits the wide application of OLED displays outdoors.

Abstract

The invention provides an OLED displayer and a manufacturing method thereof. The OLED displayer comprises a substrate, an OLED device which is arranged on the substrate and a thin-film packaging layer which is arranged on the substrate and the OLED device and covers the OLED device. The thin-film packaging layer comprises at least two inorganic material passivation layers and at least one organic material buffer layer. The inorganic material passivation layers and the organic material buffer layers in the thin-film packaging layer are alternately arranged in a laminated way, and at least one organic material buffer layer in the thin-film packaging layer is an ultraviolet-resistant film layer containing inorganic nanoparticles so as to have the effect of resisting ultraviolet radiation and enhancing the mechanical property of the organic material buffer layer, and thus the ultraviolet-resistant and photoaging-resistant performance of the OLED displayer can be enhanced and the service life can be prolonged.

Description

technical field [0001] The invention relates to the field of flat panel display technology, in particular to an OLED display and a manufacturing method thereof. Background technique [0002] Organic Light-Emitting Diode (OLED) display has the characteristics of self-illumination, high brightness, wide viewing angle, high contrast, flexibility, low energy consumption, etc. Has begun to gradually replace the traditional liquid crystal display. At present, the application of OLED display panels has become a high-end symbol from small-sized mobile phone display screens to large-sized high-resolution flat-panel TVs. [0003] Unlike traditional liquid crystal display technology, OLED display technology does not require a backlight, and uses very thin coatings of organic materials and glass substrates that emit light when an electric current passes through them. However, because organic materials are easy to react with water vapor or oxygen, as a display device based on organic m...
