"CHIPS: Doping ups OLED efficiency"

Organic LEDs promise to enable "spray on" displays covering entire walls and conforming to almost any form factor. But OLEDs' lower efficiency makes them dimmer and lower in contrast than conventional, inorganic LEDs. Now a chemist and an EE at the Massachusetts Institute of Technology claim to have hit upon a solution that increases OLED efficiency to 85 percent from 25 percent.
