Apple is planning to make a significant change in the resolution with the launch of iPhone 6, reports 9to5Mac.
The report claims the 4.7-inch iPhone 6 could feature a 1704×960 resolution display, which would be three times the base resolution (568 x 320).
The iPhone 5s comes with a 1136 x 640 resolution display, which is two times the base resolution. The report claims that Apple plans to retain the same 16:9 aspect ratio as the iPhone 5s, iPhone 5c, and iPhone 5.
This would mean that the 4.7-inch iPhone 6 would feature a display density of 416 ppi, and the rumored 5.5-inch iPhone 6 would feature a display density of 356 PPI. The report points out that Apple plans to increase the resolution to ensure that pixel density is within its threshold for a “Retina Display”.
This means that Apple will likely be tripling the aforementioned “base resolution” (568 x 320) of the iPhone screen in both directions, and that the iPhone screen resolution will be scaled with an increase of 150% from the current 2X resolution of 1136 x 640. Of course, Apple tests several different iPhones and display technologies, so it is possible that Apple chooses to take another route for display specifications for the 2014 iPhone upgrade. [..]
[..] So, regardless of whether Apple goes with a 4.7-inch or 5.5-inch panel—or both—the new iPhone(s) will have significantly more dense screens in comparison to current and past iPhones, which will result in crisper text, images, and video for users of the next-generation Apple smartphones. Also, by definition, both screens will have pixel densities that fit comfortably within Apple’s threshold for a “Retina” display.
It has been speculated that Apple will increase the resolution to 1334×750 for the 4.7-inch iPhone 6 to maintain the 326 ppi density, which is the display density of the iPhone 5s and iPhone 5c. However, the pixel tripling (3X) mode makes a lot more sense and would be easier to implement for both Apple and third-party app developers.
The report notes that Apple has been testing the 1704×960 resolution display, however it is not clear if Apple plans to go ahead with that resolution for the next generation iPhones.
Apple is widely expected to release two variants of the iPhone 6 this year, which may feature an all-new ultra thin design, narrower bezels and rounded edges. The first variant will have a 4.7 inch display, which could be launched as early as August, followed by the larger 5.5-inch model in September.
In addition to the larger screens with higher pixel density, iPhone 6 is also expected to include Apple’s new A8 processor, Touch ID fingerprint sensor, and an improved 8-megapixel camera. The iPhone 6 will also come pre-installed with iOS 8, which may include new apps such as Healthbook, TextEdit and Preview, improved Maps, inter-app communication capabilities and more.
