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 techn
