A method and apparatus for modifying an appearance of a mobile terminal are provided. A mobile terminal housing is provided with a window. A first electrode is formed inside the window. A conductive polymer layer is formed over the first electrode. An electrolyte layer is formed over the conductive polymer layer. An ion storage layer is formed in contact with the electrolyte layer. A second electrode is formed in contact with the ion storage layer. A power supply is provided for supplying a voltage to the first electrode and the second electrode, where a state of the conductive polymer layer changes from a first uncolored state to a second colored state upon application of the voltage and where the changing of the state of the conductive polymer layer modifies a visual appearance of the housing.
