Osram has announced another record breaking efficiency achievement by a flexible OLED sample.
Researchers achieved a value of 32 lm/w from the OLED, which uses a top-emitter approach, with a reflective thin steel foil substrate, rather than emitting through substrate itself. The sample was tested at a fixed brightness setting of 1000cd/m2 on a large surface integrating sphere without manipulation to help increase the light yield. The new level demonstrates the ability for OLED technology to be more efficient than halogen lamps, reports LEDs Magazine.
Osram's record for a rigid glass substrate OLED stands at 87 lm/w, indicating that flexible versions still require work to move out of the laboratory.
