Does the iPhone 4's Retina Display Ignore the Science of Optics?

The iPhone 4's new Retinal Display has lead to a staggering 960 x 640-pixel resolution for the phone's 3.5-inch diagonal screen. But are all those pixels necessary—or are they ignoring the limitations of the human eye?

Pretty interesting article.

I always wondered if there was a sort of visual-susceptible limit for screen size and resolution.

This is off-topic, but is it known what the top frames per second that an eye can see?

Mc Fadge2780d ago (Edited 2780d ago )

Because it depends on all sorts of conditions and such. Pilots have been able to identify planes that were displayed for a single frame at 240 fps (IIRC)

Microsoft_Spokesman2780d ago

Do you remember how a long time ago Sony was promising 120fps, people yelled out that there is no point 'cause you can't see it, you can actually see the difference of 60 and 120 fps?

Conloles2780d ago

@Spokesman ha yes and look they cant even deliver on 60fps

Mc Fadge2779d ago

Going to have to disagree with some of that.

First of all, film runs at 24fps

Secondly, the human eye can perceive anything about 10fps as continuous/fluid motion.

But yes, there's no exact figure of what fps the eye can see.

My phone's got a 3.7" display with a resolution of 480 x 800 and I can't even see the individual pixels with an alternating black-white pixel image.

Cartesian3D2780d ago (Edited 2780d ago )

may be you cant see individual pixels but you will see the difference of a 640*360 ,960 * 640 and 800*480 display ..

just like seeing the difference between 50fps and 100fps... those are beyond our limits but somehow we can see the difference

Increasing the resolution increases the sharpness of the picture. Look at 480p vs 1080p - increased resolution, increased sharpness (not including the other things 1080p can do).

The screen res of the lastest IPhone is just plain great and will more than satisfy those who use it.

Guys the point here is not Resolution or Frames Per Second is Dots Per Inch

When it comes to Resolution it can be pretty much unlimited
When it comes to Frames Per Second we are limited to 300FPS (if the sources are true)
When it comes to Dots Per Inch we are limited to 300 Dots Per Inch

For example
24" 1920 by 1080 monitor with 326 DPI Vs
52" 1920 by 1080 HDTV with 163 DPI

Even though the HDTV is 52" the monitor has a higher DPI meaning the HDTV will be far inferior to the monitor visually to the human eye

If for example though we had this scenario
24" 1920 by 1080 monitor with 326 DPI Vs
52" 1920 by 1080 HDTV with 326 DPI

Even though the HDTV and the monitor has the same DPI but different screen sizes the image will look 100% to the human eye, the only difference is more screen space meaning the HDTV will be far superior to the monitor as the only difference will be screen size

One finally point the iPhone 4 screen even at 4.5" with only 920 by 480 Resolution it will look are sharper and clearer than 108" HDTV at 1080p or a 30" 2560 by 1600p monitor because it has 326 DPI which is beyond what the human I can see
