CamFPD, a spinoff from Cambridge University's Department of Engineering (a way to make money privately, in other words) have fashioned the Wedge Display. It's a flat display that is only a few millimeters thick, and uses projection technology to cast images. Using an LCD projector at the end of the wedge, it bounces bounces light through the wedge until it reaches the angle at which it escapes and leaves the face of the screen as light. Could be a nice way to create an extremely flat LCD projection TV.
yeah... but by scaling the approximate dimensions as shown in that picture... a 60" projection display might be wicked thin... but it'll be about 17 feet long.
...but it seems to have a benefit over a standard projector in that you don't have to mount it on the ceiling or clear a path for the light.
And is it bendable/rollable while displaying?
Um...
...How does this work, and why is it better than directly projecting the image on a screen or a wall?
