Despite its name, the iPad Smart Cover is not particularly smart; it folds well and wakes your iPad from sleep, but that's about it.
Judging by a patent recently granted to the company by the U.S. Patent Office, dug out byPatently Apple, the Smart Cover might become a lot smarter in the future.
Titled "Cover attachment with flexible display," the patent describes a foldable cover for a tablet device with a "flexible display" built in.
Apple sees this approach as an alternative to making the actual tablet bigger.
"Increasing the display area could lead to a significant expansion in functionality. Unfortunately (...) device manufacturers generally choose between making the display and therefore the device itself larger, thereby reducing the portability or making the device and display smaller with the result of a less functional device," the patent text explains.
The advantages of having a second screen are obvious: You could have it display auxiliary info, such as the title of the song or movie currently being played on the tablet, alongside touchscreen controls. It could be used as a full-fledged second display, comparable to that of the main display; alternatively, only a portion of the cover could be a screen, with the rest reserved for solar cells.
As always, a patent does not necessarily means such a product will see the light of day soon, or ever.
What's interesting about this patent is that it was originally filed in 2011 (we covered it in August 2012), and though some of the concepts from it actually came to life (the iPad Pro's smart connector is one example), some of them are still quite futuristic. We certainly hope Apple will continue to innovate in the tablet area, despite iPad's steadily dwindling sales.
