Rumors surrounding a larger iPad started in early 2013. Korea Times claims to know that production of 12.9" displays has started. They are said to feature resolution close to Ultra HD. The new, larger iPad will launch in early 2014, according to the source.
iPad with larger 12.9" display in early 2014 - rumor
Korea Times is far from the first to report on a larger iPad. Research firm DisplaySearch, Korean ETNews, and even Wall Street Journal have all said that Apple is working on a larger iPad.
Korea Times claims that production of the display panels for the new larger iPad have started at a “first-tier” display manufacturer in Korea, which means either LG or Samsung. The source says that it will use a 12.9-inch display that is significantly larger than the current 9.7-inch display in iPad Air. The source also says that it will feature resolution close to Ultra HD, which is 3840x2160 pixels.

In an earlier report, DisplaySearch claimed to know that the new, larger iPad will use a resolution of 2732x1536 pixels, which seems unlikely as Apple usually doubles the resolution in both planes when changing resolutions. The iPad Air has 2048x1536 pixels, and if it were to double we would hit 4096x3072 pixels, which also seems unlikely and unnecessary. There is of course also the possibility that Apple will let the larger iPad utilize iOS in a different manner than current iPads.
Following the introduction of the iPad Air, rumors of a larger iPad have intensified. If the Mac line-up is indicative a larger iPad could be called iPad Pro.
