If you're still looking for the next big thing in displays - and are increasingly convinced that OLED isn't it - perhaps you'd like some laser with your monitor?

As reported over on Gizmodo - quoting an Xconomy article - a California-based startup called Prysm has developed a new display technology called Laser Phosphor Display, or LPD, which it hopes will replace traditional liquid crystal displays.

The advantages to the LPD technology are pretty impressive, if the company's claims are true: the display scales to any size or shape, including tileable displays for big screens or ribbon-shaped displays for advertising purposes, and draws significantly less power than a traditional backlit LCD - up to 75 percent less, in fact. Prysm also claims quality advantages: the lack of an LCD-style backlight means contrast levels are much closer to those achieved with older CRT-based displays, the viewing angle is significantly increased over LCD displays, and the images don't suffer from the motion blur that even the best liquid crystal screens can exhibit.

The display technology works in a similar manner to traditional cathode ray tube displays, with a laser taking the place of the tube to sweep across phosphor stripes and create a the image. Gone, however, are the bulky magnets that CRTs required - replaced instead with rotating mirrors that direct the beam where required.

Initially Prysm will be concentrating on large screens for corporations, where it hopes that the initially high purchase cost will be offset by the energy savings over time. However, the company believes that once the production has scaled up the price should drop low enough for the display to be adopted for consumer use - including computer monitors, TVs, and even mobile handsets. Quite what the timescale is on such releases isn't revealed, but it's certainly something to keep an eye on in the future.

Does the thought of a phosphor-based display - with all the lovely contrast and incredibly low black levels that suggests - fill you with joy, or would you need to see one in action before you start saving for your next TV purchase? Share your thoughts over in the forums.
