Abstract
A correction method for correcting uneven light emission of an organic EL panel, the correction method includes the steps of: supplying a predetermined signal to the organic EL panel to detect the brightness of the panel at horizontal and vertical scan positions; forming, based on a detection output thereof, correction data adapted to correct uneven brightness of the organic EL panel at a horizontal or vertical display position of the panel; storing the correction data in a memory; and reading the correction data from the memory during viewing to correct the level of a video signal supplied to the organic EL panel.
