Multi-aperture optical dimming system

A dimming device in a display that utilizes a fly's eye homogenizer that comprises a first array of lenses and a second array of lenses, the first array of lenses focusing a plurality of light beams on the second array of lenses, the dimming device comprising:

• a first attenuator positioned proximate the first array of lenses and the second array of lenses, the first attenuator comprising a first plurality of slats, the first plurality of slats positioned between light beams in the plurality of light beams;
• a second attenuator positioned proximate the first array of lenses and the second array of lenses, the second attenuator comprising a second plurality of slats, the second plurality of slats positioned between light beams in the plurality of light beams, wherein the first attenuator and the second attenuator form a plurality of apertures, and wherein the second attenuator is movable such that the second plurality of slats is moveable to close the plurality of apertures and selectively block at least a portion of the plurality of light beams to selectively attenuate light transmission through the at least one lens, and wherein the first attenuator and the second attenuator blocks substantially all light through the fly's eye homogenizer when the second attenuator is moved to close all of the plurality of apertures.

A dimming device in a display, the dimming device comprising:

• a moveable attenuator, the moveable attenuator controllable to open and close an aperture to selectively vary light transmission throughput through the display, the moveable attenuator including at least one compound V-shape edge, the at least one compound V-shape edge configured to provide a first dimming mode and a second dimming mode, where the first dimming mode provides a first ratio of moveable attenuator movement to light transmission throughput change and wherein the second dimming mode provides a second ratio of moveable attenuator movement to light transmission throughput change.

A dimming device in a display, the dimming device comprising:

• a moveable attenuator, the moveable attenuator controllable to open and close an aperture to selectively vary light transmission throughput through the display, the moveable attenuator including at least one partial attenuator structure configured to decrease light transmission throughput change relative to movement of the moveable attenuator as the aperture is moved from open to closed.
