''Pixel density, a barometer for viewing quality, should be increased to over 280 pixels-per-inch (PPI) to meet Apple's stiff requirement for screen viewing,'' said another source, who predicts that Taiwanese LCD giant CMI will see smaller orders from Apple than its Korean rivals.
The improved screens would present no problems for developers, insisted the MacRumors site, which also carried the story.
"By limiting the resolution increase to a doubling of the current displays, Apple will provide an easy transition for developers," said the site. "....Existing content can be displayed via pixel doubling to appear naturally on the higher-resolution display until it can be upgraded to the higher resolution. A similar system was used when the iPhone and iPod touch transitioned to double-resolution displays to minimise disruption to the app ecosystem of the platform."
