As expected, Samsung unveiled its upcoming foldable smartphone yesterday. The rumors were correct, and Samsung's first foldable device will have two screens - a large 7.3" foldable AMOLED that folds inside, and a smaller OLED that is used when the phone is closed. Samsung brands the display as the Samsung Infinity Flex Display.

The inner foldable display is a 7.3" AMOLED with a resolution of 1532x2152 (361 PPI). The outer display is a 4.5" 840x1960 AMOLED. The whole device seems to be quite thick and about double the depth compared to a standard smartphone.
