According to a supply chain report from The Wall Street Journal, Apple is testing iPhones and iPads with larger screen sizes. Apple is said to be considering an iPad with a screen size of just under 13 inches, along with an iPhone with a screen measuring at least four inches diagonally.
Korean news site ET News reported in May that Apple was testing a 12.9-inch iPad, and Reuters reported last month that the company is highly considering producing iPhones with screen sizes of 4.7 inches and 5.7 inches.
There is no guarantee we shall ever see these products
There is nothing to indicate that the models will make it into mass production; Apple, like many other companies, tests a large number of prototypes before deciding to launch a product.
The same WSJ‘s sources further indicate that this year will see the release of a new iPad with the same 9.7-inch 2048 x 1536 Retina display, but employing in-cell touch technology which was used on the iPhone 5 to make the structure thinner and lighter. We are yet to see if these rumors turn out to be true.
