Although the iPad 2 missed out on the Retina Display technology that equips the iPhone 4, it seems that Apple has significantly enhanced its overall quality despite the screen having the same specifications as the one on the iPad v1.
Dr. Raymond Soneira, the president of respected image company Displaymate, carried out an extensive analysis of the screens of the iPad 2 and the iPhone 4 (as well as the iPhone 3GS but sadly not the iPad v1),
He concluded that the iPad 2 has an "excellent LCD display hardware" that could be enhanced with a software update that will improve "anti-aliasing and automatic brightness controls" and that "the display on the iPad 2 delivers almost identical performance to the impressive iPhone 4 Retina Display".
He credits "existing anti-aliasing methods" used by Apple to reduce noticeable pixelation at lower resolutions and pixel density.
The iPhone 4 has a 326PPI compared to 132 for the iPad 2; the phone has a screen resolution of 960x640 pixels while the tablet reaches 1024x768 pixels.
Soneira adds that the latest hardware enhancements means that Apple could add sub-pixel anti-aliasing to the new iPad without any noticeable drop in performance, thereby reducing the need for any dramatic increase in PPI.
Also highlighted in the report is a bug in the automatic brightness control which, according to him, fails to work properly - across all mobile iOS devices - and not only hampers visual comfort but also battery life.
