Reserachers from Korea's KAIST institute developed a process to deposit OLED displays on textile substrates. The substrate uses fabrics made from several-micrometer-thick fibers. Using a planarization process the researchers created a fabric as flat as a piece of glass.
The OLED was deposited on this flat fabric using regular evaporation equipment. Using thin-film encapsulation, a lifetime of 1,000 hours was achieved. The textile OLED is much more flexible than a plasic based one, and may find uses in wearables. Of course the performance needs to be increased and this just a research project at this stage.
