Abstract
After several years of development, OLED has become an important display technology, evolving from passive matrix (PMOLED) to active matrix (AMOLED) and even branching out into OLED lighting. The organic layers in OLED devices are extremely thin, and most of them are based on chemically active materials, which are easily damaged by exposure to moisture or oxygen in the air. Moreover, thin metal layers used as electrodes are also very sensitive to corrosion, and the OLED performances are strongly affected also by the status and the nature of the interfaces between the different layers, making the OLED device a very complex and delicate ecosystem.
For these reasons we need to protect the OLED to prevent the organic materials from being damaged through the adoption of a dedicated process named encapsulation.
Several approaches are possible to achieve the goal; in this chapter, we briefly introduce the OLED process of seal encapsulation.
