Amid speculations on the release date of iPhone 6, a new report has emerged that the device would be launched in autumn this year with Apple Inc. suppliers likely to start production next month.

There are conflicting reports on the unveiling of iPhone 6 with some suggesting that it would see the light of the day at the upcoming WWDC event in June, while most media houses expect it to arrive only in September.

Apple Inc. suppliers will start mass production displays for the much-hyped iPhone 6 as early as May, with the 4.7-inch screen model expected to be launched this autumn, while 5.5-inch version could be delayed, Reuters reported citing sources from supply chain. It added that Japan Display Inc, Sharp Corp and South Korea's LG Display Co Ltd will make the screens of Apple's flagship smartphone, with the latter expected to begin first move for the production.

Both the variants of iPhone 6 are expected to have in-cell touch panel technology, according to a source, but another one suggested that film sensor technology would be used for the bigger model of the device (5.5-inch version), which could lead to delay by several months.

A research note from UBS Managing Director, Steve Milunovich (via Barron's) had earlier suggested that the 4.7-inch variant of iPhone 6 would be launched either in August or September but the 5.5-inch model may or may not be released at the same time. 

The 5.5-inch variant is also expected to be priced more than the smaller model, according to Milunovich.

iPhone 6 is expected to have a full scratch-free sapphire crystal glass screen. It is expected to sport a 4.7/4.8 inch or 5.5 inch display with a 1920x1080p (440ppi), or a 2272×1280 (510ppi), powered by the A8 chip (64-bit) and run on iOS 7.2, according to South Korean brokerage KDB Daewoo Securities.
