Samsung Display is set to mass-produce flexible OLED in November

Samsung OLED Technology

Beginning in late November, Korea’s largest display maker will mass-produce flexible OLED displays, which is the world’s first. It sets the tone by searching for contractors that will supply OLED parts.  For better efficiency and longer lifespan, Samsung plans to tweak a new display technology by applying phosphorescence materials to not only green but red light emitting materials.

The target flexible display is using plastic, which means flexible plastic: virtually shatter –proof. “Flexibility” allows for bending, and it indicates a slim look compared to conventional OLED types. Samsung’s next version of the Galaxy Note is expected to feature this technology, but, unfortunately, bending is unlikely.

As plastic breaks down at high temperatures during TFT(Thin Film Transistor) process, the display maker has to resort to a new method; removing glass from a TFT created by coating polyimide (PI) to a glass plate. For plastic, Samsung puts a spin on the encapsulation process that keeps organic materials free of oxygen and moisture. Traditionally, OLED’s encapsulation process involves attaching melted glasses.
