Abstract: Organic Light-Emitting Diode have an increasing market share year by year due to their all-solid-state, self-luminous, and high luminous efficiency. However , reliable packaging is still one of the key scientific and technological issues that plagues the field of OLED display. This article starts with a discussion of common OLED packaging methods, analyzes various structural features and defects, and then discusses the development history of thin film packaging technology packaging structures with broad prospects for development and the improvement of packaging structures. Finally, the current comparison of common inorganic thin film preparation processes and organic thin film preparation processes is summarized, and the development of thin film packaging is proposed.

Key words: OLED, thin film packaging, inorganic packaging process, organic packaging process
