Projection Display System for a Laptop Computer or a Notebook Computer

Patent filed April 25th, 1991

Here's a patent from 1990s direct-market PC maker Zeos, although I don't recall it ever coming to market. Instead of an LCD screen, it's got a built-in projector that can cast an image onto the machine's hinged portion, a roll-up screen, or any flat surface. I have a hard time believing it would have been practical with early 90's technology, but perhaps someone will revive it for the era of the picoprojector.
