Samsung display on the SID 2016 5.7 inch QHD (2560 x 1440) flexible AMOLE panel, the thickness of only 0.3 mm.

LG Display has completed the ALD research, and began to process introduction of ALD technology of flexible OLED panel, the samsung has also introduced the technology quickly.

Both companies have already completed the ALD technology research and development, and has entered the phase of the development of the commercial. Organic material for OLED, it is very fragile, especially in terms of resist water and oxygen.

In order to protect the OLED, need to be covered multilayer films. Although there are different panel number used during manufacturing (3-5 times), but it adopts the method of Vitex organic or inorganic membrane (cover).

Typically, manufacturers can use PECVD (plasma enhanced chemical vapor deposition) technique, such as Sputtering (Sputtering), and ALD inorganic film packaging technology, whereas Kateeva inkjet printing technology adopted the organic thin film deposition.

Samsung Display and LG Display, chose the PECVD the inorganic membrane technique packaging technology.
