According to predictions from DisplaySearch, Apple will be launching a bigger iPhone in 2014, with the display size tipped to be 5.5-inches.
However, it believes that Apple could launch two iPhones later this year, similar to the way it released the iPhone 5S and iPhone 5C simultaneously. The 2014 iPhone duo could launch with differing screen sizes.
The first would be offered with a 4.7-inch 900 x 1660p resolution display with a 386ppi image density, which is larger and has a better resolution and image density than the iPhone 5S (640 x 1136p and 326ppi).
The other would have the 5.5-inch display with a Full HD 1080 x 1920p resolution and 401ppi image density.
Both will apparently use the same LTPS (low-temperature polysilicon) LCD display technology used in the iPhone 5S.
These iPhone 6 models will launch alongside the Apple iWatch later this year. DisplaySearch expect the smartwatch to arrive with Apple’s first flexible AMOLED display sized 1.3- or 1.6-inches.
If Apple opt for the smaller 1.3-inch screen size, the iWatch will offer an image density of 348ppi, while the larger screen size will drop the image density to 278ppi.
High end smartphone predictions from DisplaySearch see average screen sizes of 5.7- and 6.2-inches for Android and Windows Phone devices. These display sizes will supposedly both offer a resolution of 1440 x 2560p, putting the image densities at 515ppi and 474ppi respectively.
Of course, these are all just predictions for now, but we do expect Apple to follow the trend of increasing screen sizes for the iPhone 6.
The iPhone 5 crept up to a 4-inch display from the 3.5-inch screen of the iPhone 4S, but in comparison to rivals like the 5-inch Samsung Galaxy S4 and 4.7-inch HTC One, the iPhone range seems positively tiny.
