Abstract

A transmissive backlit display is disclosed. In one aspect, the backlit display comprises a backlight and an array of transmissive interferometric modulators. Each interferometric modulator comprises a fixed and moving dielectric mirror stack. The interferometric modulators cause light within the desired wavelength range to be transmitted while reflecting at least a portion of the remaining light.
