00:06iPhone Dual uses a novel structural system with a multi-layer lamination design that keeps the
00:13display flat and provides durability. The nano textured cover layer is made from a custom polymer
00:19that has up to 40% higher stiffness than other materials used in the industry and has an Apple
00:27design coating for scratch resistance. There is high strength glass above and below the OLED panel
00:33for added protection. Viscoelastic adhesives allow these layers to glide relative to one another
00:39during folding like pages in a book so the panel doesn't distort over time. A titanium plate serves
00:46as the bottom layer to bring further durability and bringing it all together is the hinge with
00:52over a hundred tiny precision components. Carbon fiber support plates create a stiff lightweight
00:59platform for the display to rest on. During manufacturing we use AI algorithms to precisely
01:06match each individual hinge with its best fit housing to ensure perfect alignment. Anticonfocal laser
01:15progressively scans the topology of every single unit and 3D prints up to 25 microlayers of a custom
01:23photopolymer to eliminate residual waviness. The result of all of these innovations is a folding display
01:30with superior viewing quality that feels premium and flat, resists wear and meets the high standards of iPhone.
