Foldable phone opens into large OLED screen

The phone, demonstrated by Samsung, opens up into an OLED screen.
(PhysOrg.com) -- A new cell phone developed by Samsung opens like a book to reveal a larger OLED screen, essentially turning the phone into a portable media player. Samsung recently demonstrated the prototype at the FPD International 2008 tech trade show in Japan, possibly as the shape of things to come.
As you can see from the video, when the device is closed it looks like a typical cell phone. It has a small screen and a menu of icons, with the appearance of a touch screen.
When the phone unfolds, it displays a flexible OLED screen about five inches across. The material´s flexibility allows the screen to open and fold seamlessly, rather than be composed of two separate screens. The large display would be convenient for surfing the Internet, and is even large enough for watching movies or playing games.
There are no technical specifications, and most likely it will be a long time before the device is commercialized.

SD-Card compatible, with some internal memory as well.
Outside is like a nice hardcover book.
Inside is an OLED display, movies, pictures, PDF Files.
As for the folding mode of this prototype, somehow I doubt it would wear well over time. The crease where the display folds will most likely result in progressive degradation of that area, due to micro-fractures induced over time by the folding/unfolding.
epaper consumes less energy because energy is spent ONLY when changing the image. Since e-paper is made for static images (like a page from a book), it will only spend energy when you scroll or turn the page.
