Abstract
Aspects of the subject technology relate to display circuitry including pixel overdrive circuitry. The pixel overdrive circuitry includes one more lookup tables of boost values to be applied to pixel display values of a frame to be displayed, for overdrive of that frame. Each lookup table includes a lightness-blur-edge-width-based boost value. The lightness-blur-edge-width-based boost value matches a lightness-blur-edge-width of an intermediate grey-to-grey transition to a lightness-blur-edge-width of a maximum grey-to-grey transition.
