3M's Prototype Pico Projectors add RGB LEDs, Still Aren't in Your Phone

It seems that we see tiny projectors often, but never in actual phones or in devices I can imagine myself using. The tradition continued tonight with more prototype pico projectors from 3M.

They had two prototypes on view: one played video off SD cards, the other plugged into an iPhone and played videos off that. Unlike other pico projectors, these have an RGB LED inside rather than a straight white LED, which is a significant step forward. Both were very nice looking, but alas, both were mere prototypes. The projector the prototypes were based on is smaller than ever, which is great, but until we see these things built into actual phones rather than in relatively bulky separate devices, I don't know how far they'll go.
