High Efficiency Flat Light Source Invented

Scientists studying organic light-emitting devices (OLEDs) have made a critical leap from single-colour displays to a highly efficient and long-lived natural light source. If the device can be mass-manufactured cheaply interior lighting could look vastly different in the future. Almost any surface in a home, whether flat or curved, could become a light source: walls, curtains, ceilings, cabinets or tables — via Warren Ellis
