One version has screens on the inside and closes like a book.

Instead of sporting two screens on the outside and one on the inside, this concept design has an LED clock.

The back could have something like a light-up clock.

This foldable concept device doesn't close completely. It leaves a bit of a lip that could be used for a small notifications screen.
