Abstract

See full text

A reflective display includes a reflective spatial light modulator and a front light having a lightguide formed by an array of film-based lightguides coupled into a lightguide region of the lightguide. One or more light sources emit light into the array of lightguides, with light extraction features frustrating totally internally reflect light within the lightguide region such that the light exits the lightguide through a cladding region toward a light redirecting optical element that redirects the light toward a reflective spatial light modulator.
