Apple's reported 12.9-inch iPad will feature displays from Sharp while Foxconn Group subsidiary General Interface Solution (GIS) will be mainly responsible for touch modules, lamination and LCM assembly, according to industry sources.

The device will enter production by the end of the third quarter and go into mass production in the fourth. Sharp will provide Open Cell LCD displays while GIS will provide GF touch panels.

The makers were chosen due to Foxconn's close relationship with Apple and cooperation with Sharp, the sources said. Samsung Display and TPK will be secondary suppliers, with TPK responsible for touch modules and Samsung for displays as well as LCD assembly.

Heading into the second half of 2015, GIS is also expected to land a larger portion of iPad and iPad mini touch panel orders while TPK's share will decrease, the sources added.

The sources noted they estimate iPad Pro shipments will reach between 4-5 million in 2015 due to the device's fourth-quarter release.
