According to analyst David Hsieh, in 2014 Apple will introduce two different-sized iPhones.
One of these could sport a 5.5-inch display based on LTPS (low-temperature polysilicon) LCD that has 1920 x 1080 resolution and a 401 ppi density.
The other could be equipped with a 4.7-inch LTPS screen with a 386 pixel density and 1600 x 900 resolution.
The second larger screen model would enter into direct competition in the division of phablets.
The analyst also provided estimates on the display of the rumored iWatch that he believes will pack a flexible AMOLED display and can come with either a 1.3-inch screen or a 1.6-inch screen.
The AMOLED technology could also be used more frequently on tablet displays starting this year, Hsieh believes.
In terms of the iPad Pro, DisplaySearch expects the size of the tablet to be upped to 12.0 inches and a 2,732×2,048 display.
