If they're making it opaque I'm imagining that they're doing it the way I've wanted to for a transparent monitor. A second pass-through/reflective LCD just after the microdisplay is.
One like the ones on the pebble watch would allow you to selectively let light through from the outside or let it be reflective and show the microdisplay instead.
