Still, there is no one-size-fits-all solution to barrier films yet.

Recently, the two leading flexible organic light-emitting diode (OLED) display manufacturers, Samsung and LG, were reported to introduce atomic layer deposition (ALD) technology in the barrier film manufacturing process.
Currently, both Samsung and LG use alternating organic/inorganic layers to protect the OLED devices, which are extremely sensitive to oxygen and moisture (for more details, see the report “The Multi-Billion-Dollar Emerging Display Opportunities”).
However, the way they encapsulate OLED devices are different. Samsung deposits barrier films directly on to OLED devices in the fabrication process – organic layers via vacuum evaporation and inorganic layers via sputtering, a technology acquired from Vitex in 2011. LG, on the other hand, manufactures the barrier films separately on foil substrates and then laminates the films onto OLED devices. LG is already using ALD to deposit the inorganic layers, based on a Veeco’s FAST-ALD techn
