A Samsung concept cell phone was shown off at Japan's Flat Panel Display show recently. Shown in a video (below), it looks oddly square, and if you didn't know it was a cell phone, you might think it a portable media player.
Watch the video, though, and you see the secret: the screen folds in half, revealing a cell phone with a more typical appearance, including a smaller screen.
The folding was even done while the device was on and the screen active. Hard to tell, but it looks like a touch screen with the typical call and hang up keys. Windows Mobile? Probably.
Something like this could create a way for OEMs to expand screen real estate still further than even a touch screen device (iPhone) or one with a slider keyboard (G1) can allow.
On the one hand, I hate going through multiple actions to use my cell phone. That's one reason I eschew slider keyboards of any type (though I tried them, before realizing I hated them). Of course, perhaps the larger unfolded screen could be used for web browsing or viewing media.
