New iPads to sport double the resolution of iPad Air

Sources said Apple Inc. (NASDAQ:AAPL) may launch the larger screen iPad Pro (as they called it) by April 2014. And one with 4K resolution may hit the market in October when the Cupertino-based company updates its product cycle. The current iPad Air with 9.7-inch screen has 2,048-by-1,536 pixel resolution. That already falls in the 2K category. Sources said that the 4K version may have a resolution of 4096 x 3072, double the resolution of iPad Air. The upcoming device is also rumored to sport 397ppi pixel density, compared to the iPad Air’s 264ppi.

It’s not the first time the reports of a larger iPad have surfaced. Last month, The Korean Times said that a “first tier” Korean display maker is already manufacturing the 12.9 inch Retina display for Apple Inc. (NASDAQ:AAPL). Prior to that, there were reports that Apple Inc (NASDAQ:AAPL) was testing a 12.9-inch or 11.4-inch tablet. The Wall Street Journal also claimed that a large-size iPad could hit the market next year.
