I'm just waiting for tech that uses eye-tracking to put a tiny hi-DPI display that "moves around" so it stays right in line with your foveal vision, while having a static, head-wrapping low-DPI display behind it, to cover your peripheral vision.
I can't imagine there's any tech that'd let an actual LCD move around at the speed your eyes do. But maybe the foveal display could be from ultra-low-power short-throw laser DLP, bounced right into your eyeballs? It could even use the glass surface of the peripheral LCD display as a DSLR-alike mirror, so that it can reach your pupil from a straight-on angle.
What I'm describing does seem to exist (a https://en.wikipedia.org/wiki/Virtual_retinal_display) — but it doesn't seem that anybody has tried combining them with traditional LCD tech yet.
I feel like such a hybrid device would have a number of obvious operational advantages, e.g. much lower bandwidth/render-power requirements (each frame, your GPU would only have to render a high-resolution image of a little square, along with a very low-res image of the rest of the scene.)
