Abstract

Projector display systems comprising a light dimmer and first modulator are disclosed. The light dimmer may comprise an adjustable iris, adjustable light sources and/or LCD stack that is capable of lowering the luminance of the light source illuminating the first modulator. A second modulator may be provided. The first modulator may comprise a plurality of analog mirrors (e.g. MEMS array) and the second modulator may comprise a plurality of mirrors (e.g., DMD array). The display system may further comprise a controller that sends control signals to the light dimmer and first modulator. The display system may render a desired dynamic range for rendering a projected image by a combination of such control signals.
