1. A system comprising:
a display comprising a plurality of light sources; and
a display controller including drive circuits for the plurality of light sources, the display controller configured to:
determine a plurality of display zones of the display based on a field of view (FOV) of an eye of a user of the display;
drive light sources in a first display zone of the plurality of display zones based on a first relationship between input display values and luminance levels for the light sources in the first display zone; and
drive light sources in a second display zone of the plurality of display zones based on a second relationship between input display values and luminance levels for the light sources in the second display zone, wherein the second relationship is different from the first relationship.
