Like a LED, an OLED is a solid-state semiconductor device with 100 to 500 nanometers thick (it means about 200 times smaller than a human hair). You can read more about OLEDs in howstuffworks.


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.
