One of the innovations packed inside the Apple Watch—and highlighted by designer Jony Ive at the company’s grand unveiling this week—is a flexible display.

Contrary to some earlier speculation about the device, however, this doesn’t mean you can actually bend the screen. As with other devices featuring flexible displays, such as those from LG and Samsung, the display has been laminated onto a stiff pane, fixing it in place to prevent the damage that would come from repeated flexing.
