METHOD AND DEVICE FOR DRIVING MATRIX TYPE SPONTANEOUS LIGHT EMISSION DISPLAY DEVICE AND INFORMATION DISPLAY SYSTEM USING DRIVING DEVICE OF THE MATRIX TYPE SPONTANEOUS LIGHT EMISSION DISPLAY DEVICE

PROBLEM TO BE SOLVED: To reduce luminance unevenness (sticking) due to differences in deterioration degree among a plurality of light emitting elements. SOLUTION: An image data reception part 13a receives image data from an image processing circuit 15 and stores them in an image memory 13b. A sticking evaluation memory 13c stores a cumulative light emission time corresponding to the driving time of each light emitting element from the start point of driving to a current point as information showing the degree of deterioration of the light emitting element. A sticking evaluation part 13d automatically generates a plurality of pieces of image data which are interpreted to have the same meaning as the image data stored in the image memory 13b and calculate sticking indexes representing the extent of luminance unevenness as to those image data according to stored information in the sticking evaluation memory 13c. A display image selection part 13e selects image data with the minimum sticking index out of the plurality of pieces of image data and displays an image corresponding to the selected image data on an organic EL panel 11.
