Tokyo - Apple is likely to release its newest iPhone globally in September with a higher resolution and bigger screens, Japan's leading Nikkei business daily reported on Friday.

The handset, expected to be called the iPhone 6, is expected to come in two versions with a 4.7- or 5.5-inch screen, up from the current four-inch panel, the report said, without citing sources.

US-based Apple is ordering its higher-resolution liquid crystal display screens from Japanese electronics giant Sharp, Japan Display and South Korea's LG Display, it added.

Taiwan's Commercial Times reported earlier this month that Taiwan Semiconductor Manufacturing has started producing chips for Apple's next iPhone.

Apple released its current iPhone 5 in September 2012 and newer versions in the series last year.

There was no immediate comment from Sharp, whose shares rose 1.96 percent on Friday morning after the news as the broader market was flat. - AFP
