The report says that the Apple iPhone 6 will be available in two sizes, one with a 4.7 inch to 4.8 inch screen, and the other with a 5.5 inch glass. The resolution on the displays will be 1080 x 1920 and 1280 x 2272 respectively. The glass will be made of indium gallium zinc oxide (IGZO) instead of the low-temperature polysilicon (LTPS) employed on current iPhone models.
This setup would leave Apple with a three-pronged approach to screen sizes, as it will likely keep the current 4" iPhone 5s as a mid-range model, as usual. While a 5.5" iPhone "phablet" sounds rather fishy, Display Search analysis back in January reiterated that diagonal being in the cards for the iPhone, so Apple might at least be toying around with the idea. Here's what the Apple portfolio might look like this year, if the 4.7" and 5.5" iPhones indeed materialize, in a concept video designed by Enrico Penello and Ran Avni.
