We heard reports in the past that Apple passed on Sharp’s IGZO display tech for the third-generation iPad due to Sharp not having the tech ready in time. Going with Sharp’s IGZO tech would have allowed for a thinner display assembly, a brighter display with less LEDs, and the ability to use a smaller battery or extend battery life specs as a result. It could have also helped shave off some of the increased weight and depth of the new iPad. These are all things we witnessed first hand when we got up close and personal with a few IGZO demos at IFA this year.  Sharp is announcing today its first 7-inch tablet to use the display technology, claiming the 1,280-by-800 IGZO display allows for 2.5 times the battery life from the tablet’s 2,040mAh battery (via ComputerWorld).

With the iPad mini launch coming later this month, it is a possibility the tech is finally ready for Apple to take advantage. Sharp also has 10-inch and 13-inch variants of the IGZO displays, but the 7-inch would of course make a lot of sense for iPad mini given what we already know about the device. Apple’s ability to increase battery life, or simply have the ability to use a smaller battery (in a smaller form factor) while maintaining battery life specs, is just one benefit. Another big benefit for Apple would be narrow borders: rumor has it—which is something we also talked about a lot in the past—the iPad mini will have a much narrower border than previous-generation iPads. Sharp told us its IGZO LCDs can be built with a bezel under 2mm, and it was showing off a demo display with a 1.75mm border at IFA. That would definitely fit the bill for the narrow-border, one-handed experience we expect from iPad mini.

In September, Sharp told us the displays were ready for mass production by Q4 2012. It also hinted Apple is the type of company that could benefit from the technology.
