Title:
OLED DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/076483
Kind Code:
A1
Abstract:
An OLED display device, a thin-film packaging layer (400) thereof comprising an inorganic passivation layer (401), an organic buffer layer (402), and a water-oxygen quenching layer (403), wherein the inorganic passivation layer and the organic buffer layer jointly form a stacked structure, and the water-oxygen quenching layer may be a first water-oxygen quenching layer (4031) disposed between the stacked structure and an OLED layer (300), a second water-oxygen quenching layer (4032) disposed between two inorganic passivation layers in the stacked structure, or a combination of the two. In the thin-film packaging layer, by means of physical adsorption or chemical reactions and the coordinated functions with the inorganic passivation layer and the organic buffer layer, the water-oxygen quenching layer may effectively prevent damages to the OLED device caused by water and oxygen, without affecting the light-emitting performance of an OLED device, thereby improving the service life of the OLED device, while also playing a role of releasing the stress of the inorganic passivation layer, reducing the number of layers and thickness of the thin-film packaging layer, thereby making the OLED display device thinner overall and improving the bending performance of flexible OLED display devices.
