Abstract

The invention discloses an organic light-emitting device (OLED) packaging structure and a method. The packaging structure is characterized by comprising a substrate, the OLED, a thin film packaging layer, an organic resin layer and a glass cover sheet, wherein Al2O3 thin films and SiNx thin films are sequentially overlapped to form the thin film packaging layer. In the packaging method, the Al2O3 thin film is prepared by using an atomic layer deposition technology, the SiNx thin film is prepared by using a plasma chemical vapor deposition or sputtering technology, and thus, the thin film packaging layer has high compactness, water vapor can be prevented from corroding the OLED, and the thin film packaging layer making efficiency is also improved. As the organic resin layer and the glass cover sheet are arranged on the thin film packaging layer, by using the full covering effects of the organic resin layer and the protection effects of the glass cover sheet, the service life of the device is further improved.

Description

technical field

[0001] The invention relates to display technology, in particular to an organic electroluminescent device technology, in particular to a packaging structure and a packaging method for an organic electroluminescent device. Background technique

[0002] At present, organic electroluminescent devices (OLEDs) have attracted extensive attention from academia and business circles due to their advantages such as self-luminescence, low energy consumption, wide viewing angle, fast response speed, and flexibility. At present, as major manufacturers in the display industry continue to invest a lot of money in technology research and development, OLED flat panel display technology is at a critical stage where mass production technology is maturing and market demand is growing rapidly. Since OLEDs are particularly sensitive to water vapor and oxygen in the environment, the water vapor and oxygen infiltrating into the device will corrode electrodes and organic layer materi...
