An idea for virtual reality device, would it work?

I had this dream about VR and I thought of this design, I'm just wondering if I'm mashing random concepts together and missing big points in why it won't work.

In my experience of Virtual Reality which is pretty basic, (Google Cardboard on Nexus 4), the main problem I saw aside from the "screen-door effect" due to my phone's relatively low resolution (being magnified), was the problem of FOV... I could only see about a fourth or so of my regular naked-eye(s) field of view... Supposedly other devices are better, I'm not doubting that. I haven't had the opportunity to try them.

I have seen/read about radar technology with phased array systems... I've also read/seen how parabolic dishes work... I was thinking of a display where the projector was an annular ring that went around your eyes, and projected onto a "parabolic" reflective panel...

I know why over-complicate things... we've got bendable displays, shouldn't be hard to turn them into "concave-lenses"...

Hence I have learned not to hold onto ideas as I'm aware that they are worthless without execution. Also more than likely I'm missing some obvious flaw(s) that makes the idea stupid.

So this is my "napkin-sketch"... What are your thoughts?

I'd have to get into vectors of LED's and fov... also a "Data-bridge" between the two isolated computers with their respective concave-reflector/projector to connect without much lag as that's what makes people sick and a separated computer seems like a bad idea for syncing.

Just to clarify, the phased array is so that the few leds can pulse/refresh fast enough to illuminate the entire quadrant of the concave-reflector... I think the annular ring should be able to move on gimbals but not sure why...

Wow the eye has an amazing field of view, even just holding a looped string up to my eye and varying the distance from my eye as well as the diameter of the loop, I can still see it! It has to be pretty big, bigger than what I initially drew.

Do you mean it revolves around your head, creating an image by persistence of vision? Reasonable in theory. The eyes would see a full VR picture, the entire field of view. Now suppose you want 30 fps? You would have the ring going around your head 30 times a second? This becomes unwieldy, I think. Our heads tend to bob, disturbing the constant speed of the revolving led ring. The image would be unstable.

Is this similar to a rotating-led-stick clock? I think I would rather sit in front of a revolving stick, whose motion is several inches from my nose.

I don't mean any of what you said. I drew a pretty crappy picture above. Instead of looking at a screen like conventional, sane designs, I thought, what if the "pixels" were arranged in a ring, positioned just outside of your pupils (the black part) maybe as large in diameter as your eyes... the annular ring being concentric to your pupils. The projection would be aimed at a reflective "parabolic dish" that would be roughly equivalent in size if not larger than the screens in use now. But by varying the concavity, distance, size of reflective surface, you could have a very big FOV.

Anyway, I think it's a stupid idea on my part but thanks for your time.
