OLED surfaces
Thanks to research from the University of Southern California and Princeton University, almost any surface in a building, whether flat or curved, could become a light source: walls, curtains, ceilings, cabinets or tables.
Scientists studying organic light-emitting devices (OLEDs) have made a critical leap from single-color displays to a highly efficient and long-lived natural light source. The invention, described in the April 13 issue of Nature, is the latest fruit of a 13-year OLED research program led by Mark Thompson, professor of chemistry in the USC College of Letters, Arts and Sciences, and Stephen Forrest, formerly of Princeton University and now vice president for research at the University of Michigan.
“This process will enable us to get 100 percent efficiency out of a single, broad spectrum light source,” Thompson said. If the device can be mass-manufactured cheaply – a realistic expectation, according to Thompson – interior lighting could look vastly different in the future.
Since OLEDs are transparent when turned off, the devices could even be installed as windows or skylights to mimic the feel of natural light after dark – or to serve as the ultimate inconspicuous flat-panel television.
