Electronic reading devices
First Claim
1. An electronic device including an electroactive, reflective display and a light to illuminate said display, wherein said display has a viewing surface, and wherein said light is configured to provide a stripe of illumination along an edge of said viewing surface and directed across the viewing surface and through the viewing surface, wherein said viewing surface is an outer-most surface of said display and is configured to reflect light from said stripe directly to a user to allow the user to view an image displayed on said display, and wherein said viewing surface has a concave curvature towards said stripe such that said illumination from said stripe provides uniform illumination over a majority of said viewing surface.
