Apple is getting ready to grow its iPad family again, this time with a bigger 12.9-inch display model set to launch some time in the spring. Like so many other rumors, this one comes from an unnamed source in Apple's parts supply chain.
The source, according to the Korea Times, is a first-tier display supplier who also said the display will sport ultra high definition-quality, although they stop short of calling it a true 4K display.
"The 12.9-inch iPad will have improved picture quality. As the Apple partner intends to boost its lineup for displays that have almost ultra high-definition (UHD) quality, the upcoming iPad will provide very clear quality similar to that of UHD," the source said.
The displays are apparently already in production, which would fit with a spring launch window. Apple's current iPad lineup includes the iPad Air and iPad 2 with a 9.7-inch displays, and the iPad mini with a 7.9-inch display.
Rumors have periodically claimed that a larger format iPad is in the works, but so far that hasn't materialized. The idea that Apple is testing devices with different size displays is pretty much a given. There isn't any guarantee, however, that any of those designs make it to market.
Apple CEO Tim Cook has said in the past that looking to the company's supply chain for hints about upcoming products isn't a good gauge into what's really happening. Keeping that in mind, the 12.9-inch iPad gets to stay firmly planted in the rumor camp.
