“On November 10, 2011, the US Patent & Trademark Office published a patent application from Apple that may reveal some of the changes coming to the iPad 3’s backlighting system,” Jack Purcher reports for Patently Apple.

“This past Monday we learned that Apple is likely to modify LED back-light solutions for next-generation iPads,” Purcher reports. “Today’s patent may provide us with a more in-depth peek into where these modifications may be going. Some think that the iPad launching in Q1 2012 is really just a stepping stone to the iPad 3 that’s destined for a Q4 2012 release. Something like what the iPhone 4S is to the iPhone 5.”

Purcher reports, “In today’s patent, Apple discusses the use of one or two OLED backlighting units in a future iPad. Down the road, other devices adopting multiple OLED backlights may include such devices as the Cinema Display, MacBook Air and – if we hold our breath long enough, maybe an HDTV. For now however, the focus is definitely on a future version of the iPad.”
