DISPLAY DEVICE AND DRIVING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a display device which makes compensation for a change in luminance characteristics of a light emitting element, and a driving method thereof.

SOLUTION: The display device includes a displaying light emitting element provided to a display portion and a plurality of monitoring light emitting elements having the similar characteristics as the displaying light emitting element. At least one selected from the plurality of the monitoring light emitting elements is operated under a driving condition different from that of the displaying light emitting element, and the ratio of the total amount of charge flowing through the displaying light emitting element to that flowing through the monitoring light emitting element is controlled to satisfy a certain relation in view of luminance degradation. When the one monitoring light emitting element reaches a predetermined voltage or time, the connection is switched from the one monitoring light emitting element to another monitoring light emitting element that has been operated under the same condition as the displaying light emitting element.
