1. A high dynamic range high definition display, comprising:
a backlight comprising an n×m array of locally dimmed LEDs;
a reflector comprising an n×m array of reflective structures, each reflective structure comprising a set of reflective walls, with each LED being surrounded by its own separate reflective structure such that direct light from one LED does not illuminate a second neighboring LED; and
a modulating panel placed over the array of locally dimmed LEDs and the array of sets of reflective walls;
each reflector wall surrounding each LED is angled from the normal direction from the backlight such that the light originating from the LED and reflected from the modulating panel back toward the LED is substantially re-reflected by the reflector walls to be contained within a solid angle relative to the LED, the solid angle substantially reducing parallax illumination from the LED.
