Sanyo’s breakthrough short throw projector design may well revolutionize the front projector market. By radically altering traditional projection optics, they’ve been able to design a projector capable of filling a wall from as little as 3-inches away.
The LX-XL50 can be hung on a wall to project images directly below or above the location of the projector. The unique design prevents shadows from appearing on the picture.
While Sanyo’s initial target market for the LX-XL50 is classrooms and meeting rooms, I don’t think it will be long before we see similar projector designs for home theater installations. Sanyo initially plans to release the projectors in Japan in late 2007, with a worldwide release shortly thereafter.

Hmm how would this affect the light distribution of the image? the image would almost certainly be bringter at the top than the bottom..with the bulb so close to the surface. any thoughts?

Yeah, that’s a really good point. You’d think that hotspotting would be a big issue with this design, unless they’ve worked out some sort of light source system that actually is brighter at the bottom than at the top to compensate for that.
It’ll be interesting to see one of these up close and personal to see how they deal with that.

It might be possible that they’ve been able to adjust for even brightness with optics, or perhaps in the image. But, the illustration is NOT realistic. You can’t project blackness… i.e. if you are front projecting an image onto a white surface, the darkest part of the image can’t be darker than the white surface under the ambient lighting.
I would also imagine they can’t use many kinds of projection screens, because those are often designed to optimize the brightness of an image by bouncing the image back with less than a 180 deg spread.
Finally, I saw some other pictures of the unit, and it shows the SPACE between the unit and the wall is 8cm. The actual clear space needed from the wall is much greater.

We need more information and the price
