The iPad 2 didn’t get a Retina Display this generation like the iPhone 4… but there’s more to the quality of a display than just pixel density. Now Dr. Raymond Soneir of DisplayMate Technologies has performed tests
on the many other characteristics of the iPad 2′s display, putting it in a shoot-out against that of the iPhone 4.
The results? Outside of pixel density, the iPad 2 and iPhone 4 have almost identical performance. That’s a good thing on the hardware side… but a bad thing when it comes to software.
According to Soneira, the iPad 2′s LCD display hardware is excellent, but the software has numerous bugs and issues when it comes to anti-aliasing. If the iPad 2′s anti-aliasing was better, it could actually close the perceivable gap between the iPad 2′s display and the iPhone 4′s Retina Display.
There’s also a big problem with the way iOS devices control brightness. Soneira says that a bug in Apple’s automatic brightness controls locks brightness based upon “the brightest ambient light sensor value that has been measured at any point starting from the time unit was awakened.” So if you’ve woken your device up in a bright room, then turned off the lights, the brightness controls won’t adjust accordingly unless you put your unit to sleep and wake it back up.
All in all, as long as you can look beyond pixels, the iPad 2 has as good of a display as any iOS device ever made. If you can wait until the iPad 3, though? You’ll get the upped pixel density too.
