Abstract
A control device for a display panel includes a plurality of pixels each including: a self-luminous element; and a transistor that controls a current that flows through the self-luminous element, the control device including: a measuring unit configured to measure a luminescence characteristic of the self-luminous element and an operating characteristic of the transistor; and a correction unit configured to correct an input video signal that enables identifying a video to be displayed on the display panel, based on luminescence data related to the luminescence characteristic and operation data related to the operating characteristic, wherein the measuring unit measures the luminescence characteristic at a frequency that is lower than a frequency at which the measuring unit measures the operating characteristic.
