Laser TVs

Laser TV is a new visual technology using optoelectronics, which will be an improvement over current Plasma TV and LCD television displays. Their developers claim it will even make LCD and plasma screens obsolete. So if you have just decided what kind of HDTV to buy, here is something new to consider in your buying decision (although they are not due to be available to buyers until the end of 2007).

In what has been claimed to be the first of its kind, developers unveiled a prototype of a 50" laser tv that uses optoelectronic chip-laser technology, in Sydney, Australia. Arasor International, an Australian based company, is the manufacturer that produces the unique optoelectronic chip. Novalux, its Silicon Valley-based U.S. partner, developed the laser projection device in which the chip is used. This lasertv technology is now being put into effect by some television manufacturers.

To generate images, laserTVs use a red, blue, and green laser in place of white-light mercury lamps. The result is images that are brighter and deeper, having a richer, more vibrant color palette than the conventional plasma, CRT, or LCD displays, and that can be displayed on large, thin, lightweight screens.

"With laser, you can see a much larger color spectrum," said Jonathan Espy, executive vice president of Arasor. "If you look at any screen today, the color content is roughly about 30-35 percent of what the eye can see," Mr. Pelaprat said. "But for the very first time, with a laser TV we'll be able to see 90 percent of what the eye can see. All of a sudden, what you see is a life-like image on a display."

Laser televisions are said to use just a fraction of the electricity, cost less money to produce and buy, and are only half the weight and depth of the present plasma TVs. Novalux chief executive, Jean-Michel Pelaprat, believes that plasma TV is now something of the past. But Samsung, who is one of the first scheduled to release a line of laser tvs next year along with Mitsubishi, stated that, "Laser TV is one of a number of competing, next-generation formats. At this stage, it is too early to say more."

But don't look for too many manufacturers to come out with laser television technology right away. The Sydney Morning Herald contacted Fujitsu, Pioneer, Samsung and Philips to get their take on the new tubes. At present, since they have already made considerable investments in LCD and plasma televisions, there are no plans for any of these manufacturers to jump on the bandwagon any time in the near future.

Lasertelevisions are planned to be available for consumers to purchase by December 2007. The optoelectronic chip-laser technology won't be restricted to just lasertelevision. Since this technology enables the production of hi-fidelity images to be projected on almost any surface, look for home theaters, cell phones, and cinemas to implement its use also.
