  • Patent number: 6577496
    Abstract: A foldable display device coupled to a non-rigid support mechanism movable between an unfolded and a folded position. In one embodiment, the e-ink display device is dual sided and both sides can display information as well as accept touch screen commands. One side of the display device is used in the unfolded position and the opposite side is used in the folded position. In the unfolded position, the display device has a Personal Digital Assistant (PDA) form factor, and the entire area of one side of the display device is viewable. The display device is supported within the non-rigid support mechanism such that it lies in a flat plane in the unfolded position, and there is no loss of viewable area due to folding of the display device. The two sides of the non-rigid support mechanism are coupled for movement between a folded and an unfolded position and the display device is folded in a bend radius that precludes any disruption to the display area.
