Yes, the next in line for television from an american based company, Arazor.

They have come out with the new concept a few days ago with their new, plazma-sized tv that has a resolution of 1920x1080, no bs the highest res so far seen in consumer products.

The laser tv goes further, they are 2 times thinner then plasmas, lighter then lcd or plasma tvs, and use 3-4 times less power then the Plazma tvs with a better quality picture.

The cost factor considered, would be about 1/2 the price of now available lcd and plasma displays...

 

no joke, i want one!

Arasor’s ”overview” page seems to have the best description of what this tech is.

 

Looks to me like a sound and obvious “next generation” step from active matrix LCD. In place of an array of separately addressable thin-film transistors, the new display appears to have an array of (really tiny!) separately addressable lasers.

 

I’m not sure where Arasor’s claim that “other screens show 30% of the colors the eye can see, this one shows 90%” comes from – from what little I can see, it seems to use the conventional 3-color (RGB) design. Its brightness, contrast, and switching speed should blow existing technology away, however – the typical solid state laser can switch complete off at least hundreds of times faster than the eye can perceive, and has no “afterglow”.

 

I’m also not sure why they predict that LCD will continue to dominate the small screen market, with LASERs dominating the large. The technology sounds ideal for screens as small as cellphone displays, etc.

Might be because of power consumption or something :lol:

 

This sounds supremely awesomely mind-blowingly cool, though...

sure does.

 

Maybe because these lasers put out a very narrow band of frequencies they say that more of the light coming from it can be seen by your eye, and hence you would be saving on power that is otherwise unseen and wasted.

Waaaaaait a minute...

 

Lasers emit coherent light in parallel beams, which means such a screen's viewing angle should be pretty small, no? Unless it's got a diffusion screen right in front of the lasers...

Yes coherent, but that doesnt mean it wont emit in all directions. These lasers will probably be small laser diodes, where to light emited comes off a surface and not from a rod or gas chamber.

This is a common misconception.

 

The light-emitting medium in a laser, like any glowing substance, emits light in all directions. This medium is usually enclosed in a long, thin reflective, cavity, allowing only photons traveling in a narrow range of directions to escape. Often, a lens is used to further narrow the range of directions.

 

Nothing inherent in the nature of laser light requires its photons to travel in the same direction.

… Unless it's got a diffusion screen right in front of the lasers...
I suspect this is the arrangement. Any side-illuminated translucent substance is effective for diffusing a laser beam (a quick experiment with my laser pointer and a souvenir keyring fob confirms this). Also, I wonder how much of the color is due to the laser’s emission frequency, and how much due to dyes in some light diffusing medium?

 

I think what significant about this new tech is less the nature of the light it produces, than that each color pixel is an independent light source. In this regard, they’re the same as plasma displays, but much more durable, potentially lower power/light output, and with a much higher switching speed.
