Films such as Blade Runner and Minority Report tend to show tons of bright electronic signs blinking or animating frantically from buildings and vehicles alike -- a vision of future Earth that can only become true with much more energy-efficient displays than we have now. Xconomy reports on a California startup's new laser phosphor displays (LPDs) that use just 25 percent of the electricity required by today's liquid-crystal displays (LCD) or LEDs.
LPD screens can supposedly come in any size or shape, including square tiles and long, thin ribbon bands. That would allow the lights of Times Square or Tokyo to spread across many more cities and towns. Casinos and stadiums would remain shiny beacons, but train stations, shopping malls, airports, financial exchanges and even churches could also join in the lighting blitz.
The company Prysm has remained fairly tight-lipped about LPD technology, but the basic idea comes from eliminating the expensive layer of transistors that help drive each pixel of an LCD screen in HDTVs, computer monitors or smart phones. Instead, LPDs use a laser that blinks on and off precisely as it sweeps across a pattern of phosphor stripes -- not unlike older cathode ray tubes (CRTs) that use an electron beam to activate a field of electro-sensitive phosphors. And rather than the magnets used in CRTs, rotating "scanning mirrors" direct the highly efficient laser beam within an LPD screen.
A first generation of LPD screens may cost more than LCD or LED screens, but Prysm envisions savings from lower power usage, as well as the lack of lamps that could go bust and require replacement. The company also says that LPDs have higher resolution, don't suffer from motion blur, and can be seen from wider angles than the usual displays. Once LPD production has scaled up, costs may drop low enough for common usage within computers and smart phones.
Prysm first plans to target larger displays that can factor in savings from long-term operations. So keep your eyes peeled next time you go walking around the bright lights of a big city.
Wow, a company has managed to copy what Mitsubishi is doing with it's new line of TVs. Way to go, Prysm: you've discovered the ancient technology of copying what someone else did before you.
KOOL KOOL COOL COOL KOOL KOOL
Oh quit yer whining, we're gettin' lasers in our cellphones.
Islam and Sharia Law are taking over the lands in modern Europe as you read this. Make the stand today and educate yourself on this dire matter!
Ok i am confused! First i keep hering about OLED TVs which are supposed to be the TVs of the future and now Im hearing about LPDs? I dont get it!!! Ok which technology is better OLED or LPD? And finally which technology is going to be the future OLED or LPD? Someone please answer me.
There will probably be both types of TVs in the future. Just like there are plasma TVs, LCDs, and DLP right now, I'm sure there will be OLED and LPD as well as LCD and plasma and whatever else acronym comes about.
It all depends on the picture quality, expense in manufacturing each type (which results in lower/higher consumer prices) and how many other companies decide to manufacture one of the other or both.

The future is not set. There is no fate except what we make for ourselves.
The future will be a rampant mutation of technology and eventually no one will really know what all is out there and available. Too many people and too many companies will have products and inventions that span such a wide range that no one will be able to keep track.
I'm sure that if you told someone from the 1950's about all the products and inventions we have today, that person would think that it would be to much to keep track of.
I guess as to which type of TV will exist in the future... Whichever one will cost the user the most while breaking the fastest so the consumer has to repeat that overpriced purchase as often as possible without seeming to scandalous in the process.
been watching terminator a lot lately, hmm?
lasers last longer than OLED, have purer color, faster switching...
"lasers last longer than OLED, have purer color, faster switching..."
True but I can buy an oled screen today but where can you get a laser one. Also a laser display is a new type of projector so it has to be in front of the screen or behind it. Oled is the screen so you dont need extra hadware dangling else ware.
It's not really that one is better than the other its more about where you would use one vs the other. You wouldn't make a laptop or tablet or media player with a laser projector as a primary display. Perhaps it could have one in addition though to splatter your content on a wall.
The TV of the future will be wireless in every way.. wireless power from a flip-flop mag field emitted from the wall behind it; wireless audio/video from cable or sat box elsewhere in the room or house; wireless internet and phone (speech and video conference) via cellular internet and of course have build in DVR capabilities. I expect it will also serve as your computer monitor with something like Project Natal providing virtual keyboard and mouse capabilities.
This appears positive. 75 percent reduction. How much does the earlier model use? I mean is it 75 percent of what? Is it 75 percent of 110 watts. What size screen is this based on? We know the smaller the screen the less wats used, but unfortinately this article does not provide all the data, in order to make an information assessment.
