A Cambridge UK academic has come up with a completely new flat TV concept that relies on total internal reflection in a wedge shaped piece of clear plastic, fed by the same LCD video projectors that drive rear-projection televisions. The technique promises to cost about a fiftieth of the price of current plasma screens and yet deliver a similar quality picture.
Flat Projection Displays will eventually also target cheap laptop displays using the clear wedge approach, but this will only be practical once a matchbox or smaller sized projector becomes available, which Travis says is certainly on the way.
