OLEDs are great, but don't last long. The blue ones are down to half 
the original brightness after  about 3,000 hours of use. They are active 
devices, like tiny red, green and blue LEDs.

The good news is that they are "printed" using a technique similar to
ink jet printing. 

Almost infinite sized units are possible, a single piece theater sized
screen is possible. 

Estimates at this time are for handheld devices size (3.5inch) 800x600
screens to cost about $5 each in large quantities, instead of the current
$40 price for a 1/4 VGA screen. Many handheld display devices in the $200 
retail range will be able to be sold for half of that price using an 
OLED screen.

OLED TV sets, with user replaceable screens will be out soon. They will be
about 1 inch or less thick and a replacement screen will be about $100
once the novelty wears off.
