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.
