Abstract

An apparatus to determine a driving voltage includes: a color coordinate value comparator to measure a color coordinate value of an organic light-emitting display apparatus, to calculate a difference value between the measured color coordinate value and a fiducial color coordinate value, and to compare the calculated difference value with a first critical value; a voltage level changer to increase an absolute value of a driving voltage applied to each pixel of the organic light-emitting display apparatus when the difference value is greater than or equal to the first critical value; and a voltage level determiner to determine a level of the driving voltage at a point of time when the difference value is calculated as a final level of a driving voltage, when the difference value is less than the first critical value.
