With the rumoured iPad3 screen dimensions to be 2048x1536..

Would I be correct in thinking the iPad3 (if rumours continue to be true), that:
2048(pixels) ÷ 7.75(inches tall) = 264ppi?

Would that be correct? Or is my logic way off?
 
The correct logic is square root(2048^2 + 1536^2) pixels / 9.7 inches (diagonal), which leads to 263,9 PPI.
 
Isn't that less/worse than the iPhone 4?

That's what I was thinking, and why I attempted to work it out.
- So this amazing HUGE screen for the iPad3, isn't going to be as 'Retina' as the 4/4S?

(Excuse my ignorance if I've got this all wrong, but it's why I kinda asked the question).
 
I just read another thread saying that it is still considered "Retina" because yes, it's a bigger screen, but you hold it farther away from you so the pixel density doesn't have to be as high. However, I kind of hold my iPad 2 up close when watching videos or using apps...so?
 
No, it won't be quite "as retina" as an iPhone.

Yes, it will still look damn awesome.

"Retina" isn't a defined term. It refers to the distance that pixels don't look like pixels anymore, instead they look like continuous lines.

When the iPhone 4 was released, Steve Jobs said when you hold a screen about 10-12 inches away from your face, 300 ppi is the threshold of the pixels looking like continuous lines.

With the iPad, you typically hold it farther away from yourself than 10-12 inches, whether it's on your lap or on a desk, similar to a laptop. So having ta 264ppi screen may still be under the definition of "Retina" because of how you look at it...pun intended.
 
Yeah it's a bit lower than the iPhone 4 and 4S.

But that high of a resolution on a 9.7" screen is going to be amazing.

It is also going to make your laptop or desktop look terrible after you use the iPad for a while. :D
 
maybe its not gonna be as ''retina'' as the iPhone, but deffinatly a much better improvement over the current one :cool:
 
264ppi is unheard of on any 10" tablet right now. I believe the next tablet to have something "close" to that is the next Transformer Prime which will have a larger 1920x1200 10.1" display at roughly 233ppi - which will come out this June.

Samsung showed off a demo that was very close to this DPI on a 10.1" screen. But it never shipped.

The next Transformer Prime will have a pixel density of 224 pixels per inch. That's quite a bit lower than 264 pixels per inch.
 
The iPhone 4/4S has 614,400 pixels in a 3.5" display at about 330ppi.

The iPad 2 has 786,432 pixels in a 9.7" display at about 132ppi.

The iPad 3 is rumored to have 3,145,728 pixels in a 9.7" display at about 264ppi.

It won't be quite as dense as an iPhone 4 screen if you hold it at the same distance. Most people will probably hold an iPad a bit further away than an iPhone, so the difference won't be that great between a 'retina' iPhone and a 'retina' iPad.
 
The iPad 3 with retina display (if so equipped) will look great... but damn do I hate, and am I sick of, hearing the term "retina".

So my 50" Panasonic 1080P tv is "retina" because my couch, the normal viewing station, is located 6.5" from the screen where no pixels are visible and the resolution is maximized?:confused:
 
If I'm doing my math right my Air has a DPI of roughly 127.68.

So the iPad 3 will have more than twice the pixel density of my laptop.

Every time I think about that it just seems crazy. I can't wait to see this screen.

If they could get the MacBook Air up to the resolution of the 27" iMac or Thunderbolt display the Air DPI would be 220.84. Think about that. :)

Yep. Also consider that you won't be able to view a full-size iPad 3 screenshot on a 27" cinema/thunderbolt display without cropping.

Hahahahahahahahahahahahaha

If this was FB I would "like" that comment.

To be honest, I don't think I've ever been close enough to any device where I could see pixels unless I was intently looking for them.

I'm more interested in what other features iPad 3 will have -- could care less bout resolution. I mean, after all, I'd rather take a pretty girl that can do my taxes than a hot model that can't do squat.

Technically speaking the term "retina" defines a display with such a high resolution that you shouldn't be able to see the individual pixels on the display at a close viewing distance.
 
Retina display is just a marketing term that means a high dense display. If you wanted a true retina display it would be over 600 ppi, as that is the true limit for the human eye.

"Retina" is just Apple's marketing. I'm sure they'll call the iPad 3 screen "Retina" as well
