Apple iPad 3 Retina display confirmed by iFixit

0. phoneArena 23 Feb 2012, 18:06 posted on

MacRumors' comparison of the display of the Apple iPad 2 with one allegedly belonging to the Apple iPad 3 showed the newer screen with four times the pixels of the current display; the site sent the new panel to iFixit which couldn't get it to work, but did confirm the resolution of 2048×1536...

um there were pics of an a5x processor… meaning a beefed up dual core, while an A6 would be quad core. personally i think apple is going to go with the a5x.. there is really no need for quad core

lol, that picture had absolutely no specs on the processor. it probably is dual-core. but to say anything about these unannounced chips is pure speculation.

lol, so we obviously know something… its quite clear that A5x will be dual core while A6 would be quad… no, it is not certain, but with a pic for the name of a second dual core, it is logical apple reserves full numbers for full upgrades

i wonder if the mystery asus tab will have a higher ppi?

if so, there goes apple's selling point.

Not just Asus, but also Samsung is rumored to be pushing out a higher resolution tablet as well.

Don't we know already it has 1920x1200? Good enough for me.

How do you figure of the ppi?

Pixels per inch (PPI) or pixel density is a measurement of the resolution of devices in various contexts; typically computer displays, image scanners, and digital camera image sensors.

PPI can also describe the resolution, in pixels, of an image to be printed within a specified space. Note, the unit is not square inches. For instance, a 100×100 pixel image that is printed in a 1-inch square has a resolution of 100 pixels per inch (PPI). Used in this way, the measurement is meaningful when printing an image. Good quality photographs usually require 300 pixels per inch when printed.
Now how does it works?

Theoretically, PPI can be calculated from knowing the diagonal size of the screen in inches and the resolution in pixels (width and height). This can be done in steps:

Calculate diagonal resolution in pixels using the Pythagorean theorem

You need to know the size of a "pixel" is not standardized. Also, the math can be misleading since you can have two screens with same diagional display but different lengths and widths for the same pixel resolution, say 800x480. What I am saying is the diagonal display and pixel resolution is NOT sufficient since the math makes an assumption about pixel size, which may not be true.

The following website makes a key assumption that each pixel is a square and that is how you get to the 263/264 PPI for the iPad 3.http://members.ping.de/~sven/dpi.html

In summary, I measured numerous android devices with the same 4.3" diagonal display with about the same pixel resolution, but YOU CAN'T DISCERN ppi because the displays all had different widths -- HTC screens tend to be skinnier than Samsung displays despite the same 4.3" screen meaning the pixels were stretched in the Samsung devices. That theorem of c^2 = a^2 + b^2 for right triangles makes an assumption about the units being the same. Once you assume square pixels, you overcome the fact pixel sizes may not be uniform or standardized in size.

ipad 4 should have a super retina displaty,with 1000ppi.

Meh, It wouldn't even matter if they put a retina screen there or not, iFans will still buy it. All they have to do is just say it has a retina display and Steve Job's Reality Distortion will do it's job...

It could have a 4K display and I wouldn't care. It's still an oversized ipod with an oversized pricetag. Yawn.
