but the thing is, they arent blowing up any image.

projectors take, an image from a small lens, then PROJECT it onto a surface, making it bigger, therefore making each pixel bigger, so pixel density is much much lower.

this isnt projecting any image on any surface, and its not blowing up any image. there are 2 .7 inch (diagnol) screens that are really close to you face, and through special optics, fool your eye into percieving that the image is bigger. its not really 150 or 750 inches, so its not blowing up the pixels. on prejection tv, the image is actaull 150 inches, there for you have some fricken big pixels, and 720p would be trash.


It doesn't matter that they are not "blowing it up"...they are still blowing it up by putting it 1/2 inch away fro your eye. It all goes back to the screen size vs optimal viewing distance formula. 

 

VD: Viewing distanceDS: Display's diagonal sizeNHR: Display's native horizontal resolution (in pixels)NVR: Display's native vertical resolution (in pixels)CVR: Vertical resolution of the video being displayed (in pixels)

Luckily I found online an excel sheet which just asks for resolution and screen size and gives me optimal viewing distance, so I don't have to look for my scientific calculator every time I want to calculate this. :)

yeah, too bad none of that matters, because at 720p on .7 inch screen, no matter how close you eyes are, you wont be able to destinguish each pixel..

if i put my eye up against a object, im still not going to see a sub atomic particle. silly comparison put still works. 

when pixel density is that high, it doesnt matter. show me another .7 inch oled screen with a 1280x720p resolution, and then we can talk. 

if you wear these things and are able to make out the pixels, the you deseved to be worshiped, for you have suprhuman eye sight, and will have no use for microscopes

The thing is, that formula is a mathematical fact for anyone with 20/20 vision. You can't say 2+2 isn't 4...

Even all they are doing is putting a 0.7 inch screen in front of your eye, according to that formila above, at 720p it would need to be 1.2 inches away from the eye for you not to see any pixels. if its 0.8 inches away form your eye, you will see pixels more so than you would on your 50 inch 720p plasma TV at 10 feet.

The problem is that they have promissed 750 inch screen at 20 meters or 150 inch screen at 3 meters(same thing screen size relative to distance).  This screen size is not something 0.7 inch screen can give you at 1.2 inches away form your eye. Also, human eye can't focuse on an image that close. Therefore, they are using a lens to make your eye focus and most likely blow up the image... which is where most of the pixelation will occur. It won't be bad, kinda like staring at a 50 inch 720p tv from 5 feet, but it will still be there.
