Last week Jeffries analyst Peter Misek published his forecast on what he believes will be a 4.8-inch display iPhone 6.
In September KGI Securities analyst Ming-chi Kuo estimated that the iPhone 6 screen will measure between 4.5 and 5 inches.
On Tuesday DisplaySearch analyst David Hsieh claimed that Apple is testing two iPhones of different screen sizes, namely a 4.7-inch panel with 1,280 x 720-pixel resolution and a 5.7-inch display with full HD 1080p resolution.
In addition, the report suggests that new devices will be launched by Apple with increased resolution.
They include the iPad mini 2 with a 7.9-inch 2,048×1,536 display, a 12.9-inch iPad with a 2,732 x 2,048 resolution display, a Retina MacBook Air with a 12-inch screen and a 2,304×1,440 resolution, and 1.3-inch and 1.63-inch iWatch models with 320×320 flexible AMOLED display, as well as 55-inch and 65-inch 4Kx2K screeApple TVs.
