Abstract
This disclosure provides systems, methods, apparatus, and computer readable media for generating images on a display using a dithering process that takes into account an uneven spacing of available gray scale values in at least one color subfield used to generate the images. The dithering process includes generating a set of initial color subfields, a set of quantized color subfields, and a set of final color subfields, which are then output on the display. The quantized color subfields an the final color subfields are derived based at least in part on the uneven spacing of gray scale values in at least one of the final color subfields.
