So far, though, LCoS hasn't delivered big time as a TV technology, though companies like Sony are using it for projectors, particularly for digital cinemas, and JVC has a line of three LCoS TVs, the HD-IDA line, priced at $3300-4496.
So far no one's released a commercially available laser TV yet, either. But they could appear sooner than some of the other technologies. Mitsubishi, for one, plans to demo a laser TV next January at the Consumer Electronics Show in Las Vegas.
Mitsubishi's Laser TV could look like this
Laser isn't a TV type in its own right. Rather, it's a technique for improving existing designs, in particularly LCD and DLP, but also LCoS. All these approaches require a light source and have traditionally used bulbs that pump out white light which is then optically separated into beams of red, green and blue light.
Laser TVs replace the white light lamps with precisely coloured laser beams. Proponents of the technology claim the result is the ability to generate a much wider range of colours - called a gamut - than is currently possible, allowing TVs to display almost as many if not more colours than the human eye is capable of seeing.
Companies marketing rear-projection TVs - most based on DLP technology, but soon LCoS too - like laser's promise to allow them to make much thinner sets. Big projection TVs generally cost less than equivalent sized LCDs and plasmas, and laser could allow them to compete on thickness too.
Laser tech could boost LCDs
However, laser could be used to improve LCD panels too, extending the advances already being made with LED backlighting. Again, LED backlights transmit red, green and blue light separately, and have the added advantages of consuming less power and taking up less room than traditional LCD white-light bulb backlights.
LED backlight technology is advancing as quickly as other display techniques are, and when combined with image enhancement systems like 100Hz refresh rates, will undoubtedly extend LCD's life even further. Top-of-the-line LCD TVs with LED backlights are already going on sale. But you can't yet buy a laser-lit telly.
Laser or LED? The jury's out, but LED seems likely to dominate, leaving laser as the high-end backlight of choice, able to deliver more colours, but squeezed out of the mainstream by cheaper LED technology.
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<!!
