Gizmodo: OLED Factory first look

Gizmodo takes us into the future of flat screens with a look at the infant technology organic light emitting diode (OLED).

OLEDs (organic light-emitting diodes) differ from LCDs in that they don't need a backlight of any kind, because each pixel is made of a phosphorescent particle that lights up on its own when excited. The trick is getting the particles onto the glass, plastic or metallic screen—the substrate, they call it—in an orderly fashion.

OLED's promise the contrast ratio of cathode ray tubes, old fashioned TV, and the size of plasma and LCD. The biggest technical problem is the life span of the blue phosphorescent particles which fade over time. Both LCD and Plasma fade so this is not much of a problem. OLED has a life of about 50k thousand hours and, if memory serves, my Westy has a life of 50K hours.

The first OLED are coming out this season but we will have to wait until 2010 before the prices on these things come down to something reasonable. Then I will once again have a TV bigger than Bill O.
