All indications point to that Apple will present this year at least one new iPhone with a larger screen. Rumors we actually speak of two sizes, 4.7 and 5.5 inches (in this latter there may be variations), but so far it had not spoken much resolution screen that will offer those devices.
Sources close to the process of evaluation of the future iPhone 6 now speak of a resolution that will triple which was used in the first editions of these devices. Like this, We will have a total resolution of 960 x 1,704 pixels, something that is supported by the logic of previous jumps in screen size and resolution of the iPhone.
Explain it in 9to5Mac, which reminds us that the first iPhone had a resolution of 320 x 480 in those diagonals of 3.5 inches. The thing improved much with the iPhone 4 and Retina displays, which brought the resolution to the 640 x 960. Doubling the effective resolution of the first generations, and also doubled the density of pixels to reach the 326 DPI current.
In fact, that pixel density remained in the iPhone 5, 5S and 5 c, because although screens increased in size to reach the 4-inch diagonal, the resolution increased only in the vertical. These devices had a resolution of 640 x 1,136, but in reality, for the developer perspective, the effective resolution was 568 x 320, rather than the first iPhone’s 480 x 320.
Hence comes the calculation: in the future iPhone 6 – or as you want it to baptize them Apple – multiply by three both the horizontal base (320) resolution and the vertical (568). And that gives precisely as results the 960 x 1704 pixels. The screen density would be 416 ppp in 4.7-inch screens, and 356 ppp where appeared an iPhone with 5.5 inch.
This provided leap seems that it makes sense from the point of view of the developer. These you won’t have to do seemingly great efforts to adapt your applications and games, except perhaps when it comes to include something more defined graphics so certain elements do not have a “blurred” Finish to increase screen resolution.
