It does matter... They ARENT blowing it up, you don't get that, they are simply using the optics to FOCUS. Same way glasses work to focus. Do glasses blow up an image? NO.

Therefor, size does matter, because there is a BIOLOGICAL THRESHOLD. You don't seem to get that, I was a Biology Major for a year, and even though I switched, I learned a great deal about the eyes mechanics. There is a point, concerned with size, at which the eye loses its ability to distinguish individual objects. These pixels, since they are NOT being blown up, cannot be individually distinguished by the human eye, as they are far past the point at which an eye can recognize. Do you understand? A robotic sensor for instance, at this distance, may be able to distinguish, using your calculation, however a human eye has its limits, which your particular calculation does not account for.

I am sorry, I just don't agree and I am pretty sure I'm right.

Doesn't matter if they are magnifying it or not.

Even if there is absolutely no magnifying and they are placing the OLED 0.6 inches away from your eye (thats how close it needs to be to appear 750 inches at 20 meters and 150 inches at 3 meters), and then placing a lens in between to help your eye "focus" for an image that close,  you will see pixelation. Yes, human eye, with 20/20 vision will see pixels on a 0.7 inch 720p screen if its 0.6 inches away from it and in focus.

In order not to see pixels, the tiny OLED screen needs to be 1.2 inches away from your eye...but at that distance, you wouldn't be getting an image equivalent of 750 inch screen at 20 meters, so they would have to blow it up to make it look that big. Its lower pixel density no matter if they blow it up or not...

1080p for this image size would be perfect btw. And they should be able to do it, as Texas instruments can cram 1080p resolution using 2 million tiny mirrors in to a 0.6 inch chip.


The size argument I am talking about doesn't have ANYTHING to do with the particular focus, I'm talking about the same reason we can see objects under a microscope that we can't see with the naked eye. It's the biological threshold of what we can see due to SIZE. There is a LIMIT to what the Human Eye can see, and the size of these individual pixels are far beyond that limit, regardless of how close to our eye it is, your formula, whether you like it or not, does not address that.

Also, you would be getting the equivalent of a 750 inch screen at 20 meters. You do in fact realize, that at that size, it will take up your entire field of vision, correct? Thats already been stated that this takes up, even most peoples peripheral vision, therefor giving the EQUIVALENT. You need to start understanding biology, and the limits of the human eye to understand what I'm talking about. Both Biology and Tech come into play here, you need to start addressing both.
