iPad 3 Said Thicker, with Smart Cover

The iPad 3 is likely to be thicker than its predecessor, according to a report, but will support the Apple Smart Cover.

Macotakara, a Japanese technology blog with a dubious track record on Apple rumors, said that an Asian supplier which is providing parts for the next-generation iPad that the screen size will be the same as the iPad 2 but will be thicker for an “unknown reason.”

While the report might seem a little doubtful in origin, it isn’t the first time we’ve heard about the next-generation iPad being thicker than its predecessor. Just last month, iLounge reported that the iPad 3 would be around 0.7mm thicker than the iPad 2.

This additional thickness is apparently required to accommodate dual-light bars needed for a higher resolution display. The higher resolution display, which is likely to be four times the current 2048 by 1536 according to reports, will need more than just a single LED light bar to maintain its brightness.

However, more recent reports cast doubt on the dual-light bar theory, with Apple planning to use Sharp’s IGZO (indium-gallium-zinc) LCD panels for the iPad 3 instead.

IGZO technology could be a good solution to Apple’s requirement for high-resolution, low-power displays as it doesn’t require the IPS (in-plane switching) panel technology to provide wide viewing angles, nor will it necessitate dual-bar LED backlighting
