The next incarnation of the iPhone will launch with a 4.7-inch screen while a 5.5-inch version may be delayed, according to Reuters.
In a post out of Tokyo early Tuesday, Reuters quoted unnamed supply chain sources saying that Apple's suppliers -- Japan Display Inc, Sharp Corp and South Korea's LG Display Co Ltd -- will start making 4.7-inch displays for the iPhone6 as early as May.
The report says that in-cell touch panel technology will get built into the screens, which will be developed with "thinner construction than with standard touch panel films - that was introduced with the iPhone 5."
Rumors about the iPhone6 have picked up recently. Earlier this week, Japan's Nikkei newspaper said that Apple's new smartphones would debut in September.
Apple introduced the iPhone 5 in September 2012 followed by last year's follow-up debuts of the 5S and 5C.
