DisplayMate Technologies just released the results of a head-to-head comparison between the iPad 2 and the iPhone 4 screens. Except the fact that the iPad 2 display is not ‘retina-grade’, the results show that the display is as good as its iPhone 4 counterpart. From a hardware standpoint, the display is rated “excellent,” with great power efficiency, effective screen contrast, picture quality and color and grayscale accuracy. However, the report also suggests that Apple is not taking full advantage of the capabilities offered by the new display, as software changes could make the iPad 2 experience look even better. DisplayMate Technologies mentions the fact that the iOS user interface is lacking basic features such as advanced anti-aliasing, which would help compensate for the display’s lower pixel density – after all, thanks to the additional power offered by the new Apple A5 processor, implementing better anti-aliasing mechanisms into iOS should be a breeze.
