Hi...

Or, how about neon lamps instead?

Maybe with a wheel spinning in front of them? ;^)

A NEON zoetrope...LOL

The problem is that LED pixels are many times more expensive than competing
technologies like LCD's and plasma. For the small size you need the same
number of pixels as for a large screen, it's just not economical, you'd just
have a $10k 20" TV.

A friend just dropped in his new Blackberry, and he states that the
new screen is just that......thousands of multi-colour LEDs!

The neat part about it is that it requires no backlight

Give them enough time, those darn engineers will come up with
anything!

21" - I'll bet this baby cost more than $10k. Pity that there's no picture
of the thing...

LED TV is being worked on. These are in the class of organic LED's.
There are plans to eventualy come out with monitor and TV screens for
general applications. The LED size would have to come down to match the
LCD and Plasma screens for the dots.

The LED technology itself is not the problem. The problem is to make
htat many LED's fit together properly, have the necessary heat
dissipation, and also put out the necessary lumination for this type of
application.

Samsung is about to announce a replacement for the Plasma and LCD
screens using organic LED technology:

Yes. You did get the sarcasm, right?

Well, there is a technology called OLED being developed. a LED screen can get
made somewhat like LCD screens are now; it's claimed to be bright and offer
better off-angle viewing than LCD, but it's not ready for prime time yet.
Apparently they have a short life.

I've heard of progress made on printable organic LED's, but last I looked
into them they still had a number of hurdles to overcome. If this is in fact
what's used I'd be curious to know more about it, either way it's not LED's
in a conventional sense.

OLED is real, folks. At the CES in Las Vegas, I saw an OLED pocket TV
with built-in hard drive recorder, intended to retail for about $600.
Not the brightest picture I've ever seen, but absolutely gorgeous
otherwise. Looked the same from any viewing angle, and was more like a
CRT picture than any LCD or plasma I've ever seen. Lifetime? No idea.
But it was mighty nice.
