Abstract
Methods, systems and apparatuses may provide for technology that generates a seed value, wherein the seed value is dedicated to a position of an input pixel, generates a dithered pixel value based on the seed value and a value of the input pixel, and conducts a scan-out of the dithered pixel value to a display panel. In one example, the technology generates an intermediate value based on the seed value and one or more fixed constants and generates a pseudo random number based on the intermediate value and a programmable constant, wherein the dithered pixel value is generated based on the pseudo random number and the value of the input pixel.
