Abstract

A control device includes: a state acquisition unit configured to acquire first state data regarding a state of a first element included in a first self-light-emitting pixel included in a display panel and configured to emit first color light, and second state data regarding a state of a second element included in a second self-light-emitting pixel included in the display panel and configured to emit second color light longer in wavelength than the first color light; and a compensation processing unit configured to perform first compensation of compensating for a temporal change in the first self-light-emitting pixel based on the first state data, and perform second compensation of compensating for a temporal change in the second self-light-emitting pixel based on the first state data and the second state data.

Claims (5)

1 . A control device comprising:

a compensation processing unit in which

after a first display is performed in a first region included in a display panel including a plurality of first self-light-emitting pixels configured to emit first color light and a plurality of second self-light-emitting pixels configured to emit second color light longer in wavelength than the first color light, and after a second display is performed in a second region included in the display panel, a voltage to be applied to a second self-light-emitting pixel included in the second region is made higher than a voltage to be applied to a second self-light-emitting pixel included in the first region,

in the first display, a first self-light-emitting pixel included in the first region emits the first color light at a first grayscale value, and a second self-light-emitting pixel included in the first region emits light at a second grayscale value higher than the first grayscale value, and

in the second display, a first self-light-emitting pixel and a second self-light-emitting pixel included in the second region emit light at the second grayscale value.
