Abstract:
A display device includes: organic light emitting diodes configured to emit light depending on grayscales constituting a target frame; a power voltage supplier configured to supply a power voltage to one electrode of each of the organic light emitting diodes; and a power voltage determiner configured to: extract target grayscales in descending order from a highest grayscale among the grayscales; and determine a voltage value of the power voltage based on each number of the target grayscales.
