As well as the super-thin, next-generation TV’s we’re all looking forward to, organic light emitting diodes, or OLEDs, also hold great potential as a light source. They are extremely energy efficient, dimmable, can produce many different colors, emit light over an extended area and the light they produce is diffuse and non-glaring. The thin, flat nature of OLEDs also makes it possible to create light sources in a wide variety of shapes and sizes. However, until now, the physical characteristics of OLEDs have meant they have had to be powered from low-voltage direct current (DC) sources. Philips Research has now developed the first ever OLED module that can be powered directly from a mains electricity supply.
