ABSTRACT:
A flip screen magnifying system for a cellular telephone having a base portion and a top portion including an information screen. The base and top portions are hinged such that the top portion may be folded with the screen proximate the base portion in a closed position and opened to expose the base and the screen to the user in an opened position. A thin Fresnel lens magnifying film is secured to the top portion over the information screen by a pair of cantilever springs on opposite sides of the screen. The lens is movable between a contracted position proximate the screen in the telephone closed position, and a normally biased extended position spaced away from the screen to magnify information thereon in the telephone opened position. The lens may be manually adjustable to permit change of magnification when the telephone is in the opened position.
