1. A display device, comprising:
a display panel;
a backlight device comprising a plurality of light sources to illuminate the display panel, wherein the plurality of light sources are configured such that color of light emitted from the plurality of light sources varies with luminance levels of the plurality of light sources; and
a display driver configured to:
process a first input grey level of a first color for a target pixel of the display panel based at least in part on a specified luminance level of a corresponding light source of the plurality of light sources to determine a first output grey level of the first color for the target pixel, wherein the first color is red, wherein an x coordinate of color of light emitted from the corresponding light source in an Yxy color space increases as the specified luminance level of the corresponding light source decreases in an in-use range of the specified luminance level, and wherein the first output grey level of the first color is less than the first input grey level of the first color,
process a second input grey level of a second color for the target pixel based at least in part on the specified luminance level of the corresponding light source to determine a second output grey level of the second color for the target pixel, wherein the first output grey level and the second output grey level are determined to compensate for a change in color of light emitted from the corresponding light source, and
update the target pixel based on the first output grey level and the second output grey level.
