Technology

Lasers are an ideal substitute for the UHP lamps[citation needed], which are currently in use in projection display devices such as rear projection TV and front projectors. Current televisions are capable of displaying only half of the visible spectrum of colors[2]. One major claim of laser advocates is the ability to produce undiluted, perfect colors allowing precise hue mixing. With the color enhancement capable with lasers, up to 90% of the spectrum that is currently unviewable could be regained.[2] Other improvements that lasers advocates claim are bulbs that will never blow out, and increased efficiency by using two-thirds less power than traditional rear projection televisions.[2]. Historically, however, lasers have been too bulky and expensive for widespread adoption.

The laser technology advocates claim that the technology will allow displays with a richer, more vibrant color palette than the conventional plasma, LCD or CRT displays.[2]

They also claim the displays will:[3]

* be half the weight and cost of Plasma or LCD displays * require around 25% of the power required by Plasma or LCD displays * be very thin like Plasma and LCD displays are today * have a very wide colour gamut * have a 50,000 hour life
