Abstract: A luminance controller according to example embodiments includes a gamma set selector to select a reference gamma set from among first through N-th gamma sets respectively corresponding to first through N-th reference luminances, based on a target luminance of a display panel; an initialization voltage selector to select an initialization voltage corresponding to the reference gamma set, from among first through N-th initialization voltage offsets respectively corresponding to the first through N-th gamma sets; a common voltage selector to select a common voltage corresponding to the reference gamma set from among first through N-th common voltage offsets respectively corresponding to the first through N-th gamma sets; and a determiner to determine a target initialization voltage based on the target luminance and the initialization voltage, and to determine a target common voltage based on the target luminance and the common voltage.
