Abstract
A method of compensating luminance of a display panel, the method including respectively measuring, at different time points, test luminances of the display panel driven by test data while a multi-time programming (MTP) operation for setting the luminance of the display panel respectively for one or more gray values is performed, and deriving a luminance equation representing a relationship between a driving time of the display panel and the luminance of the display panel from the time points and the test luminances.
