DISPLAY DEVICE AND ELECTRONIC DEVICE

摘要

The display device of the invention includes a light emitting element, a monitoring light emitting element, a constant current source which supplies a constant current to the monitoring light emitting element, a time-based measurement circuit which measures time to supply a power source to the light emitting element, a memory circuit which stores V-I characteristics with time of the light emitting element, a correction data forming circuit which forms correction data based on an output of the monitoring light emitting element, an output of the time-based measurement circuit, and the characteristics with time, and a power source circuit which corrects a power source potential based on the correction data and supplies the corrected power source potential to the light emitting element.
