Abstract
A device may include an electronic display having multiple illuminators that generate light at a first wavelength and a quantum dot layer that converts a portion of the light from the first wavelength to a second wavelength. The first wavelength may vary based on a brightness level of the illuminator, and the amount of light generated by the illuminator that is converted to the second wavelength may vary based on the first wavelength. The electronic display may also include a display pixel to regulate the light emitted from the electronic display at a pixel location based on compensated image data. The device may also include image processing circuitry to determine a luminance contribution to the light from the illuminator for the pixel location, determine per color component compensation values based on the luminance contribution, and generate the compensated image data based on the per color component compensation values.
