Abstract
A retractable visual display is movable along a longitudinal axis of the visual display from a retracted position within the device housing of the portable communication device to an extended position where at least a portion of the visual display is exposed outside of the device housing in the extended position. The visual display is off when retracted and power is supplied to the visual display only in the extended position although the communication functions are active when the visual display is retracted within the device housing. In some circumstances, a secondary display presents limited information when the visual display is retracted.
