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.
Samsung showed a prototype device but did not reveal any more specifications, the expected release date or the price. It did not even name the device yet (rumors suggest Samsung will call it the Galaxy X or Galaxy F). It is likely that Samsung aims to ship this device in early 2019, and the price will probably be quite high.
Earlier this month Royole launched the world's first foldable OLED device - the FlexPai phone/tablet. The FlexPai has a 7.8" 1920x1440 (308 PPI) AMOLED display, when unfolded, The FlexPai display folds outwards, and when folded the device has three different displays (front, back and spine).
