Abstract: This, disclosure provides systems, methods and apparatus for improving the angular light distribution of a display apparatus. Smaller shutter-based display apparatus that modulate light passing through at least two apertures in an aperture or light blocking layer can provide similar viewing angle characteristics as larger shutter-based modulators by disproportionately reducing the width of a subset of the at least two apertures in relation to the remainder of the apertures. As the width of such apertures is one of the primary determinants of viewing angle, allowing a greater percentage of the light throughput of a shutter assembly to pass through wider apertures helps maintain a wider viewing angle for the display.

Abstract: This disclosure provides systems, methods and apparatus for modulating light to form an image on a display. A light modulator in the display may include a substrate, a shutter, a first actuator and a second actuator. The shutter can be configured to selectively obstruct an optical path through the substrate. The first actuator can be configured to move the shutter in a first direction along a first axis in a plane substantially parallel to a plane defined by the substrate, thereby moving the shutter from a first state to a second state. The second actuator can be configured to move the shutter in a second direction along a second axis. The second axis can be substantially orthogonal to the first axis and also within a plane parallel to the substrate. In some implementations, moving the shutter along the second axis moves the shutter into a third state.
