Manufacturability of OLED Encapsulation and Light Extraction by Russell Kurtz, Ph.D.

Applications for OLEDs in lighting are opening unique possibilities for designers; however, the organic materials make OLEDs more fragile than LEDs. A higher-index Luminit Light Shaping Diffuser® developed into a barrier film could be an excellent substrate for OLEDs, encapsulating them while simultaneously supporting them. OLED materials are also particularly sensitive to organic solvents, water (humidity), and oxygen. To protect OLEDs from these chemicals, an OLED can be encapsulated in a material that (1) does not use organic solvents, (2) prevents transmission of humidity and oxygen, and (3) does not support a static electric charge (which would destroy the OLED). Although organic light-emitting devices (OLEDs) don’t currently enjoy the commercial success in general lighting of its more established parent, the inorganic light-emitting diode (LED), applications for OLEDs in lighting are opening unique possibilities for designers.
