Abstract
A magneto-optic display diffusion lighted by incident light. A conventional magneto-optic display comprising a polarization analyzer sheet, a magneto-optic chip, and a polarizer sheet are mounted with the polarizer sheet on the front surface of a transparent slab having a diffusion surface on its back surface. The edges of the slab are adapted to direct incident light against the diffusion surface and cause diffused light to pass out through the magneto-optic display to illuminate it from behind by diffused light. In one embodiment, the edge is a reflective edge. In another embodiment, the edge is a refractive edge.
