Abstract

A control device includes: a monitoring control section configured to obtain, from within a sweep range, a measured value related to a characteristic of a pixel circuit including: a light-emitting element; and a drive transistor configured to control an electric current flowing in the light-emitting element; a correction parameter determining section configured to determine a correction parameter based on the measured value; and a signal correction processing section configured to calculate a drive voltage value for the pixel circuit by correcting a gray level value based on the correction parameter, wherein the monitoring control section determines the sweep range based on a reference measured value that is a previously obtained measured value.
