OLED illuminated surfaces


Before we have take a look on transparent OLEDs , now researchers at the University of Southern California and Princeton University have developed white-light OLEDs (organic light emitting diodes) that can cover just any surface, walls, ceilings, furnishings, and accessories, and become a light source.

The new OLEDs are the result of 13 years of research by Mark Thompson of USC and Stephen Forrest of Princeton, who previously invented single-color OLEDs but, until now, have been unable to overcome the fast burnout time of the white-light types.

The trick, as it turned out, was to use a fluorescent dye for the blue component of the OLED instead of a phosphorescence one, which consumed too much energy.
