INTEGRATED MODULATOR ILLUMINATION
First Claim
Patent Images
1. A display device comprising:
- a transparent substrate having a front side and a back side, the back side configured to face away from a viewer;
an array of spatial light modulators on the back side of the substrate, each spatial light modulator comprising a movable mirror configured to reflect modulated light out through the front side of the substrate;
an edge illuminator residing at one edge of the substrate and configured to inject light into the one edge of the substrate, wherein light propagating from the edge illuminator propagates through the substrate due to total internal reflection from the front side and the back side of the substrate; and
reflective elements on the front side of the substrate, the reflective elements configured to reflect the light to the array of spatial light modulators.

Abstract
A spatial light modulator includes an array of elements to modulate light in accordance with image data. The modulator has a display panel having first and second surfaces arranged adjacent to the array of elements such that the second surface is directly adjacent the array of elements to allow a viewer to view an image produced by modulation of light The modulator may also include a light source to provide light to the display panel and illumination dots on the first surface of the display panel to reflect light from the source to the array of elements.
