The potential is staggering, Doc A. No backlight presumably means longer life and low power consumption. The OLED panels are very light, thin & also flexible (
)- conceivably you could make a HUD with them in a car, no? This technology
should totally kill LCD off, and probably plasma, too. But it could also be a rival to FPTV, too, depending on the cost. And if it becomes practical to make very large screens.
Imagine- you buy a 100" screen that requires no PJ, and simply unroll it from a tube! Okay, you'd probably need a frame that contained P/S, input jacks, etc etc., but I'm 'blue skying' here.
Also imagine a small (say, 2"x4") full color monitor on each of your component in place of an LED readout. Or a small full color panel on your universal remote. With the low power consumption of OLED it would be practical.
