Samsung recently introduced a much rumoured/anticipated smartphone of the decade, a foldable phone – Galaxy F at its SDC2018 event last week. Although, we just got a glimpse of the device and its interface. But a new report from Korea reveals the various innovations that make such devices possible.

These Hardware’s Makes Foldable Phones Possible
The Galaxy F comes (or will come) with a flexible OLED display made by Samsung Display, which also happens to be the company behind the flexible screens inside the iPhone X, Galaxy S, Galaxy Note, and Pixel phones. But you know, just because the OLED screen is flexible, it doesn’t necessarily mean any of these phones will bend.
Apart from the display, there are several other hardware components required and ETNews (a Korean site) gave us a sneak peek at the suppliers who will make the Galaxy F (and other phones like it) possible.

Sumitomo Chemical is the company that is manufacturing a new kind of flexible display cover to replace glass for Samsung, which is rigid. That material is called transparent polyimide (PI), and that’s what you’re going to touch when interacting with foldable devices.
Samsung Display has also developed a particular type of optically transparent adhesive film that’s used to attach the various display components, including the polarizing film, touch film, and cover. According to the report, Samsung Display has been developing the glue for some five years, as it is crucial to ensure the great stress that comes from folding the device won’t do any damage to any of the screen’s layers.

Not just that, according to a report, Samsung chose the same “M8” OLED display that’s been used in many of Samsung’s flagships, including the Galaxy S8, S9, and Galaxy Note 8. All these OLED screens received positive reviews when those devices came out.
The phone also requires a new polarizing film and a hinge structure that allows the entire chassis to fold. Nichido Denko and KH Vatec are the suppliers for these parts, respectively. The hinge is without a doubt, arguably as important for a flexible phone as the glass replacement, but ETNews doesn’t offer any details about it.
Last but not least, the report suggests that Samsung intends to mass-produce the new screen in the coming months.
