A portable electronic device includes a portable electronic device housing having a surface and a primary, light-emissive display. A display skin covers a portion of the surface of the portable electronic device housing. The display skin provides a secondary, light-reflective display. The display skin includes an optically active layer comprising electrooptical material. A first electrode layer is disposed on a first side of the optically active layer proximal the surface of the portable electronic device housing. A second electrode layer disposed on a second side of the optically active layer distal of the surface of the portable electronic device housing. Electronic circuitry selectively activates the optically active layer such that images including portions of a document are selectively displayed by the display skin. The display skin is capable of maintaining a display of a selectively displayed portion of the document while the primary display is in an unpowered state.
