With the iPhone 6 set to come in two separate display sizes — a 4.7-inch model, and a 5.5-model — Apple needs to increase the iPhone’s resolution to keep up. But what will the new resolutions be? Up until now, Apple has stuck with 326 pixels-per-inch for all Retina iPhones, but will larger iPhones require higher pixel densities.
Pulling out a spreadsheet, Daring Fireball’s John Gruber worked out the math for what he thinks the resolutions of the iPhone 6 will be. Using the Pythagorean Theorem, Gruber says that he thinks the 4.7-inch iPhone 6 will keep the current iPhone’s 326 pixels-per-inch, but the 5.5-inch model will have an astonishing 461 pixels-per-inch, making it practically Super Retina.
Thanks to abundant casing leaks, we all think we know what the iPhone 6 will look like when it’s released this summer: a 4.7-inch slab of aluminum with stripes on the back denoting where the antenna goes. But do we really? A new report out of Asia says the iPhone 6 could look very different than the leaks we’ve seen so far.
In the past, when Apple has grown the screen of an iOS device — for example, with the transition from the iPhone 4s to the iPhone 5 — Apple has taken pains to keep the pixel density the same. The Retina Display on the iPhone 5 is 326 pixels per inch, just like the iPhone 4s. This makes it easier for developers and helps prevent the widespread fragmentation seen in the Android operating system.
With many rumors pegging the forthcoming iPhone 6 as having a much bigger 4.7-inch display, a practical issue presents itself: what would that mean for resolution and pixel-density? If Apple increases the display size, will they increase the resolution to compete with the likes of HTC and Samsung’s 1080p Android smartphones? And if so, what does that mean for app developers?
Apple is considering a buyout of a division of Renesas Electronics that specializes in display chips for smartphones. The buyout would give Apple engineering expertise to help improve the iPhone’s display “sharpness and battery life,” according to Japanese business site Nikkei.
Apple already orders all of its liquid crystal display chips from Renesas, and the Japanese company is responsible for powering about a third of the world’s small to midsize LCDs. Instead of using the chip division of Renesas like an outside contractor, Apple wants to bring it in-house.
