An OLED is a form of LED. Unlike an LED, OLEDs come in a sheet form and can thus be made in to any shape and bent into any form. In the comming years OLEDs will replace LCD’s and Plasma screens leading to super sexy milimeter thin screens.
The one concern about the Electroluminescence is that it runs on an very high voltage, but with low current. Motorla has a cool patent going back to the 80′s and it outlines a nice voltage reguator that ups the voltage from DC to AC.
I hope to making some more prototypes soon, and testing the battery life of such a display.
