Abstract
According to an aspect of the present disclosure, a luminance difference compensating method of a display device includes measuring a sensing voltage variance at a node between a first driving transistor and a second driving transistor of a sub pixel; calculating a first threshold voltage variance of the first driving transistor from the sensing voltage variance; calculating a second threshold voltage variance of the second driving transistor from the first threshold voltage variance and a prediction information; compensating for a first data voltage based on the first threshold voltage variance; and compensating for a second data voltage based on the second threshold voltage variance, and the prediction information is a difference value of the first threshold voltage variance and the second threshold voltage variance according to a stress bias and a time.
