Canon also claims the close proximity of the electron source and the display phosphor means SED screens consume very little power. It also plans to manufacture the electron emitter arrays and associated wiring by spraying materials onto a glass substrate in exactly the same way inkjet printers spray ink into the page. This, the company reckons, will make SED TVs cheap to produce, though such has been the cost of development, we don't expect over-the-counter prices to upset LCD and plasma makers.
Intel's abortive LCoS chip
Working with Toshiba, Canon has announced that it will soon be able to make commercially available SED TVs with screen sizes of up to 55in. Indeed, the two have been promising SED TVs 'real soon now' for the last three or four years. Hindering their plans has been litigation from Texas-based Nano-Proprietary, a company that maintains Canon wrongfully shared its carbon nanotube technology with Toshiba. Remember SED's tiny per-pixel electron guns? They're made from carbon nanotubes.
While the legal fight looks like it's near its conclusion, it has persuaded Canon not to release SED TVs this year and not even say when they will debut. Some observers hope it can get the out sometime in 2008, but there's an undercurrent of pessimism in many reports that suggests the technology may never make it to market. Toshiba sold its share of the joint-venture established with Canon, leaving Canon as the only company likely to produce SED TVs. The legal battle with Nano-Proprietary may have left it too tired to bother.
If SED fails to take off, there's always LCoS (Liquid Crystal on Silicon). Once favoured and quickly abandoned by chip maker Intel, LCoS uses standard chip-making techniques to embed tiny LCD pixels onto the surface of a chip that contains all the circuitry needed to turn them on and off. The pixels are mounted above a reflective layer. The picture is produced on the chip and cast onto a screen by reflecting light off the chip and magnifying the reflection up to full screen size.
Early LCoS TVs use three chips, one for each of the primary colours, but a more advanced version of the technique displays the three colours on one chip, the colours shown in rapid succession so quickly the eye sees the three images as one.

The big advantage with LCoS is that it improves as chip production develops. Switch the chip from, say, 90nm production to 65nm production, and the smaller size means you can cram more LCD pixels on the chip, upping the resolution. As production yields improve, LCoS chips get cheaper, and it's this application of processor production economics that first attracted Intel's attention.
Samsung brought out a handsome-looking prototype 40-inch OLED TV a couple of years ago. Has anyone heard anything about progress from Samsung on this?
Tomorrows World Russian demo
Anyone remember the LASER TV demonstrated on TW many years ago?
It consisted of a disc of lasing crystals the were energised by a CRT scan from the back. The picture was always 'in focus' but the demo was only in sepia - diffferent colour lasing was not demonstrated. Or did I dream the whole thing.I think it was shortly after the Soviet Union collapsed.
GOOD CALL ON C R T MONITORS & TV SETS
The mindless techno freeks are the ones
feeding fires of big industry, shure tech advances
are to be because life goes on.
but the life times of the new video displays really
suck. i do not personally plan to replace my C R T'S
just because they are not the latest & greatest thing
to go and >>SPEND MONEY ON<< as that is what big
industry wants .
has anyone ever taken into account that the new tech
items COST- MORE TO BUY , AND HAVE SHORTER
LIFE SPANS HMMMMMM WONDER WHY= big buisness
GREED. they dont care about the consumer but they do
care about there bottom line & there proffitt's from the junk
they continue to get the masses hooked on with some fancy
an OLED display is a wonderfull thing for BLOW & THROW junk
some where it must have printed on it MADE BY KLEENEX as
that is the original HI TECH BLOW & THROW necessity.
if you keep several C R T monitors remember to power them on
for several minutes each week to keep the capacitors & CRT tube
its self from going soft.
i to have several C R T type monitor spares and will continue
to keep them as long as i can BECAUSE IT CAN BE >FIXED<
when they break UN LIKE THE NEW BLOW & THROW >JUNK<!!
right so none of this is any good compared to a CRT I can watch beautiful full screen video and my dad who has a flat screen LCD gets fuzz both PC monitors one cost a lot more than the other (the LCD is more) and still does I will hoard CRT's I am not young and so I will have the best viewing technology around until I die Plasma screens at one point were supposed to last about three years which is ridiculous for how much they still cost you know none of these new screen techs are worth a shit and yet I still see mindless eager rubes drooling over them.
Well when you want a projection device built into your mobi, I think laser is the only option, and to be fair a bit of sparkle can be tolerated in this usage, highly mobile/demonstartion only type package, I can see LCoS & laser being a perfect in chip package.
