SPATIAL LIGHT MODULATOR WITH INTEGRATED OPTICAL COMPENSATION STRUCTURE
First Claim
1. A spatial light modulator comprising:
- a substrate;
a plurality of individually addressable light-modulating elements arranged over the substrate and configured to interferometrically modulate light transmitted through the substrate; and
an optical compensation structure;
wherein the plurality of individually addressable light-modulating elements is arranged between the substrate and the optical compensation structure.

Abstract
A spatial light modulator comprises an integrated optical compensation structure, e.g., an optical compensation structure arranged between a substrate and a plurality of individually addressable light-modulating elements, or an optical compensation structure located on the opposite side of the light-modulating elements from the substrate. The individually addressable light-modulating elements are configured to modulate light transmitted through or reflected from the transparent substrate. Methods for making such spatial light modulators involve fabricating an optical compensation structure over a substrate and fabricating a plurality of individually addressable light-modulating elements over the optical compensation structure. The optical compensation structure may be a passive optical compensation structure. The optical compensation structure may include one or more of a supplemental frontlighting source, a diffuser, a black mask, a diffractive optical element, a color filter, an anti-reflective layer, a structure that scatters light, a microlens array, and a holographic film.
