Scientists from Philips Research Laboratories have developed the first-ever organic light-emitting diode (OLED) module that can be powered directly from a mains electricity supply. The prototype opens the door to OLED systems that can be directly plugged into standard power outlets without the need for bulky power management circuitry. This will reduce the bill of materials and simplify luminaire design for future OLED-based systems aimed at mass-market general illumination applications.
