Transparent Screens

[live2game2003]

Dai Nippon Printing Co. is releasing a screen that is fully transparent. It is a transparent material such as plastic coated with a special liquid crystal substance that only reflects back light from the projector. It also includes the SoundVu technology which is another transparent membrane that is used as a speaker.

i bet if you sanded glass a bit and projected a picture on it, you would get a similar result.

I would say that this is basically a clear plastic projector screen with a chemical in it to reflect certain wavelengths of light, and then allow light that we see to pass through it, so it seems transparent. If the whole room was lit with a light that was of a similar wavelength, then the screen would be rendered useless. I could only see this as a cheap way to have screens outdoors, without damaging any hardware, and only the screen. Good concept, it feels futuristic. lol..

I was thinking that it would be better if it didn't need a projector. Projectors are fine for cinemas, but not so great at home because they need more maintenance and need to be well positioned (on the ceiling really) to avoid shadows.
