This and a piece of vellum

Green-laser micro-projectors green-lighted

Microvision’s PicoP Display Engine is small – very small. Microvision lists the size of its evaluation kit (PDF) as 60-by-68-by-10 millimeters (2.36-by-2.68-by-0.39 inches), but EETimes reports that the OEM version will be squeezed into a 20-by-40-by-7 millimeter (0.79-by-1.57-by-0.28 inches) package.

Why wait for foldable e-ink or oled? One of these with a suitably engineered rear-projection screen would do just fine. (It could do front-projection too, but you just know everyone would be sticking their fingers in the beam to make shadow pictures.)
