First Ever Nano Emissive Flat Screen Display Prototype, Full story at http://www.physorg.com/news4031.html

http://www.physorg.com/news4031.html

I heard about this technology a couple of years ago, but I didn"t think it"d show up that fast.
I wonder if it"ll give cheaper flat panels.

What would be good is that this technology could finally replace books in
some applications-like reading in bed. The screen could finally be a light-weight
alternative to hulking laptops and tablet computers.

I can't understand what you're saying... the screen can't display anything without a computer attached to it!

Actually, the screen could display something wirelessly, but it would have to have some sort of receiver attached. Anyway, the technology for what Richard wants is to be found in OLED's, not LCD type displays.

The beauty of this new technology is that it can and will significantly lower the cost of flat panel displays (according to the article about an order of magnitude). Low cost plus CRT like performance spells winner in my book. I could finally get a second display for my computer.

similar to canon's SED in what way?

The implications go far beyond computers. Imagine entire walls, anywhere, cheaply produced. They left out a very significant detail... what about the power requirements? It is, after all, a phosphor, isn't it?

...well, so? We've already got computers small enough to fit in the spine of a book that have more than enough power to run a simple ebook application. Check out gumstix or something...and by the time this technology matures and hits market, computers will be even smaller. Lots smaller.

The real obstacles here I'd think would be flexility and durability. But I'm just guessing.

A good read on HDTV technology can be found here:

While all the 'demonstration' points are good, there was no mention of "How black is black" which is a problem with all HDTV sets right now. CRT technology simply cannot be beat in that area.

The 'Black == Grey' contrast problem is one of the things that is causing me to defer any HDTV purchases and hang on to our RCA MM36100 CRT television.

Data could easily be loaded onto small onbaord flash memory that could be used to store your "book". computer wouldnt be necessary or wireless

So, how do the power requirements compare to existing LCD or OLED display technologies?

$400 for a 40" screen? I don't think marketing will let that happen... (though it would be nice if it does happen)

I don't like how it mentions "the manufactured cost would be $400" as this points to a much high "consumer" price point. Although over $1000 could be a better price, it's still far out of most consumer price ranges, considering a $300 27" Flatscreen CRT still looks especially nice.

Just remember the careful phrasing;

This is a 5 inch chunk FROM a 1280, 40-inch display.

If you drop it down to book-width, lets say 6 inches, then you're talking about far lower resolution than 1280. If the 40 inches in diagonal and we (winging it) take that as a square, then it's about 28 inches across for 1280, 6 goes into 28.28, 4.7 times, be conservative and call it four, that means the display resolution of the prototype at 6 inches is only about 320 pixels, which would be pretty annoying for a book reader. It actually works out to 271 pixels (for a square, which this is not.) Put another way, this is a very low DPI, suitable, I think, only for television at a distance.

1280 at 40 inches isn't all that impressive, either. My 19 inch (diagonal) LCD monitor is 1280 horizontally, so it's about double what they're describing here.

It'd certainly be great to have a $400 or so 40-inch 1280 HDTV, but I think what you're looking at here is manufacturing cost, which will be heavily marked up, followed by a long, long lead time before we see the product, by which time, one has to ask: Where will LCD's be by then?

Plus, I have a 30 inch Toshiba HDTV that is a CRT... it was about $700 when I bought it, less now. It's deep and extremely heavy, so the geewhiz factor isn't the same, but the image is stunning -- and frankly, I watch it from the front, I don't carry it or stare at it from the side. If you're not short on space, then what does this new, low DPI technology get you? It's far too low a resolution for small monitor use, at least compared to the LCD's you can buy now.

I dunno, maybe I'm just a grinch.

I could not find any info about power consumption - does anybody know?
