Abstract
This disclosure provides systems, methods and apparatus for modulating light to form an image on a display, as well as methods manufacturing such apparatus. The display apparatus includes dual-level shutter assemblies. Each dual-level shutter assembly includes front and rear light obstructing levels positioned adjacent to respective front and rear light blocking layers. The front and rear light blocking layers define apertures providing optical paths from a backlight to the front of the display. The dual-level shutters selectively obstruct these optical paths to generate an image.
