A newly published Canon Japan patent might reveal the future of Canon DSLR LCD screens... and that future is massive and flippable. Originally spotted by Canon Rumors, the patent details a hinged rear LCD that is so big it hides all of the controls on the back of the camera underneath it.

As you can see from the diagrams (or read in the patent itself) the LCD is capable of lifting upward, then reversing, and is specifically designed to avoid obstructing the camera's viewfinder. This makes it possible to view an image from the uplifted LCD and use the viewfinder during the same session.

While a hinged DSLR rear display is nothing new, Canon's patent shows a design that would allow for a large and reversible display unlike anything we've seen before. In fact, the LCD shown in the patent's illustrations covers the entire back of the camera, making it necessary to tuck the rear dial and several buttons behind it, though several others are exposed on either side of the viewfinder.

As with every patent, there's no indication of whether or not Canon has plans to incorporate this design into an upcoming camera, but it's one of the more curious Canon patents we've run across.
