Apple has long touted the crisp resolution of its "Retina" display that debuted in the iPhone 4 with a resolution of 326 ppi (pixels per inch), a display that has since made its way to the iPod touch and now the iPhone 4S. The Retina display concept is also said to be set to make its way into the iPad 3 next year, with Apple preparing to quadruple the number of pixels to offer a resolution of 2048 x 1536 on the device's 9.7-inch screen.

Magnified comparison of Toshiba's new 498 ppi display with lower-resolution displays
Toshiba is now pushing the idea even further, today introducing a new 6.1-inch display offering a resolution of 2560 x 1600, coming in at 498 ppi.
This newly-developed world-class, high-definition LCD panel is based on our processing techniques for forming fine-pitch and high-performance, low-temperature poly-silicon (LTPS) thin-film transistors (TFT) on glass substrates, and other precise fabrication techniques which have been cultivated over the years. This direct-view LCD panel achieves high-definition images with photographic quality, and although the images are displayed in 2D format, they impart a sense of depth and realism.
Apple obviously does not currently offer a mobile product in the range of 6.1 inches and other considerations such as ensuring a smooth transition from lower-resolution displays would likely preclude the company from utilizing this exact display, but it is clear that the technology is advancing rapidly to enable ever higher display quality. As mobile devices continue to see increased graphics capabilities and costs fall into line with existing technologies, such ultra high resolution displays are likely to see significant adoption.

New 6.1-Inch iPhone?

No don't think they would do that. No but that's probably a good screen.

Lol. New Galaxy Nexus 2. It'll be released in 2 months following the release of the Nexus next month.

You know Android will use it. Lol.

Small question

if the human retina can't see more than +-300 pixels per inch, why put 600 on 1 inch? You would think that the difference wouldn't matter. I would think that it's more important to make bigger retina display's (retina iMac, iPad?)?

What's the point of a display that's significantly higher than 300dpi? (Yes - I realize the iPhone 4 is 324ish). You're eye isn't going to notice the difference between an image that's 300dpi or one that has higher pixel density. Unless you're holding it right up to your eyeball...

Don't get me wrong - I think this is great. I just am having trouble figuring out any practical applications for this sort of pixel depth. Would there be any tangible benefit to the increased cost?

I do dream of the day when 30in. monitors that are capable of 300ppi are affordable...

Do not think it is a phone nor would anyone try to do that.
It would be a small tablet. Heck when dell put out there 5 in phoneish thing even they did not even pretend it was a true phone. They treated it more as a small tablet that could do phone stuff.

Ceddie - I may be wrong but I think the 300ppi theory of being the max we can see is based at a viewing distance of about 12 inch. This said why you would use the device any closer is questionable!

Good step in the technology, shows what is possible and opens the doors for more super high quality displays to follow

So, a larger screen iPhone with Retina display is possible then, correct?

I think the 300dpi theory is for AVERAGE human eyes, so 50% people are able to see more detailed stuffs :p

I agree that the focus should be on increasing size and not density. However, 498 ppi is safer than 326 ppi. It is unlikely that the a person can differentiate pixels at a density of 326 ppi from a distance of 12 inches, but it is impossible for anyone to differentiate pixels at a density of 498 ppi at any distance. :D

Keep in mind the term "Retina Display" is Apple marketing speak. I am guessing they will be fairly fluid with the definition, and continue using it for the high-res iPad, which after pixel doubling will not reach 324ppi.

From what I understood 500ppi is about as much as the human eye can discern, so it makes sense to get the technology to this point. Even if we rarely have our devices less that 12" from our faces.

It woudnt. But that wont matter when Samsung tries to sell new Android phones comparing specs alone, and FANdroids moaning about its 'superiority' against the iPhone.

Some people can see Apple’s retina display pixels, in some circumstances, when held unnaturally close to the eye.

This is a 6” display you can hold really close to your eye and still not see pixels. Finally!! :D

That would be a nice PPI for a head mounted device.

Indeed. In that case, the screen might be very close to the eyes, possibly less than 6 inches. Could be very nice. Will never forget my excitement over VR (Virtual Reality) way back when, then sat down in an arcade machine and didn't understand why everything looked so crappy. lol. Hey it was decades ago and I was young. :)

I believe 300 is the view limit at around 18 in from the face. Someone did the calculations on it and it worked out to be something like 18+ in.
