An organic electroluminescent material is sealed within the outer housing of a portable radio telephone along with the control grids to cause the material to luminesce in a pixilated pattern. The pixels are controlled to both create a decorative design on the housing of the telephone and to generate a user input-output region and a display region. A touch screen may be included within the user input-output region.

Communication module having selectively programmable exterior surface

An electroluminescent backlit device utilizing light-emitting polymers (LEP) is disclosed. A sandwich of LEP material and two electrical conductive materials are used to provide back lighting for a keypad or display. The electrical conductive layers are etched to form channels which provide current to and excite the LEP material to produce light at predetermined points. The etchings are directed around existing electrical contacts to facilitate normal operation of the underlying host system, such as a cellular telephone.

LEP electroluminescent backlit keypad for a cellular phone

An organic electroluminescent material is sealed within the outer housing of a portable radio telephone along with the control grids to cause the material to luminesce in a pixilated pattern. The pixels are controlled to generate a visual alarm which flashes a warning to a user as either a message or a flashing color of the housing or image. The visual alarm may be combined with audible and vibratory alarms within the mobile telephone.
