Abstract

A portable information-processing device with a color changing case includes a transparent case covering the device that contains a layer of color-changing electroluminescent film. When the electroluminescent film is subject to different potential level signals, the color of the film changes, so that the color of the case of the portable information-processing device may be altered as desired to increase the visual diversity of the product.
