Highly efficient organic light-emitting diodes

(PhysOrg.com) — Organic light-emitting diodes (OLEDs) are seen as a promising replacement for the liquid-crystal displays (LCDs) used in many flat-screen televisions because they are cheaper to mass-produce. Zhikuan Chen at the A*STAR Institute of Materials Research and Engineering and co-workers have now shown how meticulous engineering of fluorescent molecules can dramatically increase OLED efficiency.
