My theory on ultra high resolution related to the NHK article

(no offense to the highly educated of the video/graphics forum)

Inspired by this article we saw on DailyTech.com:
http://www.dailytech.com/NHK+D...n+HDTV/article7466.htm

I am theorizing that there will be (or can be) an HD resolution standard of the future that renders further advances superfluous. Eh?

Human photoreceptors:
http://en.wikipedia.org/wiki/Rods_and_cones

"The human retina contains about 125 million rod cells and 6 million cone cells"

Math:
x * y = 131,000,000 total rod cells and cone cells
(assuming they have equal importance even though some are only "gray-scale" in a sense. Also, both eyes receive comparative overlapping pictures, since we focus on the same point with both, so we only need the number of an individual eye's receptors)

16y = 10x
(I know vision isn't 16:10, but just for reference)

x = 1.6y
1.6 * y2 = 131000000
y = (131000000 / 1.6)-1/2

x = 14474.57 y = 9048.48

If you round out for comfortable display size, I would make it a 15120 x 9450 panel. That's 81 1680 x 1050 panels. A little outrageous by contemporary standards, but mathematically feasible in a decade or so.

Does anyone know more about optical receptors? Is my logic too much of a generalization? I'm fascinated with the concept of a display panel that could theoretically display images or real-time animation with the same level of detail of the human eye; essentially a window into another world!

Found this on audioholics.com:

http://www.audioholics.com/edu...cuity-of-human-vision/
"Staring straight ahead the average person has a stereoscopic field of view (not including peripheral vision which allows nearly a 180 degree field of view) of about 100 degrees...

...For angles smaller than 1 degree we use arcminutes and arcseconds as a measurement. An arcminute is equal to one sixtieth (1/60) of one degree...
...In other words, the average person cannot see more than two spots (pixels if you will) separated by less than 2 arcminutes of angle."

Doing the math, I come up with 100 degrees > 2 arcminutes > 100 degrees / (1/30 degrees) > 3000 = 3000 x 1875 resolution. According to that statement, if Digital Cinema is 4096 x 2160, then DLP theaters already have enough pixels, but you must sit close enough to have a 100 degree view of the screen (pretty damn close).

So unless you're pressing your nose onto this thing, the Ultra HD spec they were talking about on DailyTech is plenty!
