More Information
Summary:An organic light emitting display device includes: a compensator configured to extract current information of organic light emitting diodes in pixels; and a timing controller configured to determine a luminance compensation amount corresponding to the current information and to generate second data by adjusting bits of first data supplied from an outside, the first data being adjusted corresponding to the luminance compensation amount, wherein the compensator is further configured to divide a current variation corresponding to deterioration of the organic light emitting diodes into k sections and to calculate the luminance compensation amount using a linear function of a luminance variation corresponding to the current variation at each of the k sections.
