Abstract
A method of obtaining overdriving data includes providing a first data voltage corresponding to a current line reference gray level to a second pixel for first and second data writing times for first and second pixels in a first frame, measuring first luminance based on the first data voltage, applying a second data voltage corresponding to a previous line reference gray level for the first data writing time in a second frame, providing a third data voltage of an overdriving voltage corresponding to a predicted overdriving gray level added to the first data voltage for the second data writing time in the second frame, measuring second luminance based on the third data voltage, and determining an overdriving value corresponding to a reference gray level pair of the current and the previous line reference gray level as the predicted overdriving gray level when the first and second luminance are the same.
