Apple may be about to launch the Apple iPhone 6 in June with a display of 4.7 inches said Sun Chyang Xu, the Chinese analyst. The handset could go into production in May and it might arrive with a display of 1136 x 640 according to predictions. This would be the same resolution as the Apple iPhone 5S.
There is also a rumour that this year Apple will launch a handset with a display of 5.7 inches, which may arrive with a higher resolution display. Either one or both could have the VCM OIS patents that have been talked about recently.
This seems to confirm an earlier rumour that was going around, courtesy of the supply chain of Apple, about two display sizes. The release date would happen to fall in line with the WWDC, which takes place on 10 June.
Apple launched two versions of their iPhone last year, the iPhone 5S and 5C, so two devices could become the norm.
