According to this story, Sony have indicated a viewable lifetime of about 30,000 hours.

Now, I don't know if that means "After every 10,000 hours you'll have to have a technician come out to re-adjust your white balance", or if that means "It'll look pretty good for about 30,000 hours of use, and after that it'll suck until you do something".

As long as it's totally organic, that's cool. Man. Let's do the time warp again!

Really? Oil is totally organic.

Doesn't "OLED" stand for "Organic LED?" Do I have it wrong, again?

Oh, no, you are quite correct. OLEDs ARE 'Organic Light Emitting Diodes' as opposed to the standard silicon ones. I was just yanking your chain a little bit by point out that petroleum is ALSO an organic compound. Since it is a major component of many (if not most) plastics, odds are that it is used in the manufacture of OLEDs as well.

All I'm pointing out is that just because something is 'organic' doesn't necessarily make it any more eco-friendly than something that is NOT 'organic'.

Organic has a special meaning in chemistry - Organic chemistry is interested in molecules that have carbon in them. Hence, OLEDs are built from carbon based substances rather than silicon based substances.

Some forms of OLED can be printed onto a surface, potentially making them cheaper to produce than LCD. However, this won't be something you can do at home - moisture in the air destroys the polymers typically used in OLED displays.

Someone might want to remind Yahoo that Plasma displays don't have a backlight either - the phosphors used emit light on their own when an electric current is applied...

And then there was the guy who allegedly lived 'til he was ~90. His secret? He ate a big gob of petroleum jelly every day. Ack!

The 45w figure is a little deceptive, as it is based on a measurement taken with 1/3 of the pixels active. I'm not sure how representative of the real world that measurement is.

For LCDs, by far the most dominant power consumption in the device comes from the backlight, so it doesn't matter how many pixels are active. It should also be noted that there are ways to make LCDs more power efficient (such as dynamically modulating the brightness of the backlight, depending on the light-level required by the video signal) to both increase dynamic contrast and to reduce power requirements.
