A method, medium, and apparatus compensating for differences in the persistence of phosphors in a display panel. The method of compensating for differences in persistence of phosphors in a display panel, having two or more light-emitting elements with different response characteristics, may include compensating for the response time of a first light-emitting element that represents the longest response time, selecting data response time for a second light-emitting element, which is different from the longest response time, and compensating for the differences in the persistence of phosphors due to a difference between the response times of the first light-emitting element and the second light-emitting element by compensating for the selected video data based on the compensated video data for the first light-emitting element.
