Abstract
An elastomer display system comprising a transparent silicon elastomer and electrodes for establishing a nonuniform electric field in the transparent silicon elastomer. Organic fluorescent centers are disposed within the transparent silicon elastomer. The electrodes are shaped in a desired configuration to ensure creation of the frost deformation in the transparent silicon elastomer when a predetermined voltage signal is applied to the electrodes. The frost deformation functions as a scattering center for the fluorescence derived from the organic fluorescent centers, thereby displaying a desired pattern.
