AU Optronics (AUO) has reportedly reached one million in panel shipments for the iPad mini after months of efforts to increase yields, according to industry sources.

Due to AUO's yield issues throughout the second half of 2012, cumulative shipments of the iPad mini were less than Apple's originally estimated 10 million units. However, the sources said AUO has solidified higher yields as of the first quarter in 2013, which will help keep the iPad mini in supply as well as most likely push up AUO's tablet panel shipments on year in 2013.

AUO currently provides AH-VA wide-angle panels for the iPad mini while LG Display, Apple's other main panel maker for the device, provides IPS wide-angle panels.

Meanwhile, AUO is reportedly also working on panels for Apple's next-generation iPad mini.
