Sanyo has unveiled a short-throw laser projector that can display a 100in high-definition image it claims is brighter and has more vivid colours than anything else on the market.
The prototype projector builds on Sanyo's ultra-short focus technology that makes use of a large diameter aspheric lens and high-precision aspheric mirror to project a large image from a short distance. The company already has a short-throw projector on the market, the LP-XL51, but that uses a conventional lamp as its light source and manages an 80in image over just 8 centimeters with a brightness of 2,700 lumens.
Compared to these specifications, the prototype is in an altogether different class.
Sanyo has switched from a bulb to a laser light source resulting in a much brighter and richer picture. Efficiencies in light usage result in a projected image with brightness of 7,000 lumens, which is a record for laser projectors, said Reina Mito, a Sanyo spokeswoman.
The use of a laser and an improved image processing engine also means the projected image has a colour range of about 170 percent that of a standard NTSC image. That means colours are about twice as rich as could be expected from an LCD television, Sanyo said.
It can also project bigger images managing a full high-def 100in image over 63cm or a 150in image over 94cm. These combine to give the projector the shortest throw ratio yet accomplished with such a projector, said Mito.
Compared to the commercial model its also bigger - much bigger. The prototype is an impressive 2.4 metres long by 51cm by 63cm, which puts it into the same league as a large piece of furniture. Part of the size is due to its nature, prototypes are rarely small and compact, and partly from the use of a laser light source and the new image processing that has gone inside.
The size will be reduced as Sanyo takes the technology closer to commercial production. Development continues and while there are plans to commercialize the technology, there's no set timeframe for doing so at present.
Sanyo is initially aiming the technology at use in places like conference rooms and halls and for digital cinema or digital signage applications.
