<p>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.</p> |
