Abstract
A display device is implemented that can more efficiently compensate for degradation of drive transistors by promptly determining an average degradation level of the drive transistors on the entire screen. The display device is provided with a total current measuring circuit () that measures, as a total current, drive currents flowing through all of a plurality of pixel circuits or two or more pixel circuits in a state where a specific image is displayed; a determination data storage unit () that holds determination data used to determine whether to perform characteristics detection monitoring for detecting characteristics of the drive transistors; and a determining unit () that determines whether to perform the characteristics detection monitoring, based on the total current and the determination data.
