  • Patent number: 6996426
    Abstract: An electronic device such as a mobile telephone has a large touch screen display (1). On top of the display a flexible keypad (11) can be pulled up to more or less cover it. The keys (19) of the keypad act at their bottom against the surface of the display and produce, when depressed by the fingers of a user, a pressing force on the surface of the display, that by electronic circuits in the device is translated to a corresponding input figure or letter. The keypad can be the Venetian blind type and comprise lamellae (13) hinged to each other, so that each depressible key is placed completely on a single lamella. Guides (15) for the keypad are arranged at two opposite edges of the display, not allowing any part of the keypad to project outside the general profile of the device when moving the keypad. Such a movable keypad can be easily handled, is robust and not apt to be broken.
