iPhone 5SThe iPhone could one day come with buttons and controls that blend right into the background, effectively making them invisible.  Granted to Apple by the U.S. Patent and Trademark Office, a patent dubbed “Disappearing button or slider” describes how various controls on the iPhone and other devices would normally stay hidden and fully appear only when needed.  A button would be made of the same material as the housing of the phone, so it would blend in seamlessly. But it could be selectively backlit through small holes to pinpoint its location, or the backlight itself might be activated when you tap the button.
