1. An apparatus for displaying an image, the apparatus comprising:
a plurality of sets of LEDs, each LED being independently-controllable, each set of LEDs corresponding to a different pixel of a display; and
at least one lens positioned over the plurality of sets of LEDs, the at least one lens arranged to control an emission angle and an emission profile of light emitted by the LEDs, the sets of LEDs configured direct light through the at least one lens toward a first location with a first emission profile based on a first control signal and direct light through the at least one lens toward a second location with a second emission profile based on a second control signal, the light forming a first image that is viewable from a first viewing direction and a second image, unrelated to the first image, that is viewable from a second viewing direction.
