Design of iPhone 6 'locked down,' claims analyst

Cowen and Company says the design of the iPhone 6 is decided. The investment firm also has something to say about the rumored 13-inch iPad.

How large will the iPhone 6's display be? It's a done deal at 4.8 inches, says Cowen and Company.
How large will the iPhone 6's display be? It's a done deal at 4.8 inches, says Cowen and Company.

A consensus of analyst speculation is building for an iPhone that's not quite 5 inches.

After a spate of recent speculation about Apple's next iPhone, Cowen and Company analyst Timothy Arcuri has chimed in, claiming an iPhone 6 with a 4.8 inch display is locked down, as reported by AppleInsider.

That will also include higher-speed 802.11ac Wi-Fi connectivity.

Updates to iOS may center on changes to iBeacon, Touch ID, and Passbook, as Apple pushes further into mobile payments, Arcuri said.

The screen size jibes, more or less, with that in an earlier research note from NPD DisplaySearch. That note cited a 4.7-inch display as a possibility for the iPhone 6, as did a China-based analyst, who predicted a June release.

The jury is out on resolution, however. And there's talk of a larger-size phone.

Regarding the latter, DisplaySearch threw out the possibility of a 5.5-inch iPhone 6. The Chinese analyst also made that claim, saying the larger device may come later, after the 4.8-incher.

But keep in mind that something as large as 5.5-inches would bring Apple into phablet territory and out of the range of comfortable one-hand use, which Apple to date has emphasized.

Another rumor worth noting is the expectation that Apple will stick with LTPS (low-temperature polysilicon) LCD -- the same technology used in the 5S, according to DisplaySearch.

If accurate, that would put Apple at odds with Samsung and its radically different Super AMOLED tech.

The Cowan and Company analyst also predicted the release in 2014 of a 13-inch iPad that will "blur the lines between tablets and PCs."

Earlier this month, DisplaySearch said that a future "new iPad" would use a 12.9-inch 2,732x2,048-pixel display -- that would basically be the same pixel density as the iPad Air.
