Classification: CPC G | IPC G

Claim 0:
1. A display device comprising:
light-emitting units disposed in an emission area and including at least one element set including light-emitting elements implemented as light-emitting diodes;
a first storage unit that stores temperature data of the at least one element set; and
a compensator that extracts a first element set having temperature data of a higher temperature than an average temperature among the temperature data of the at least one element set and compensates for image data based on the first element set to generate compensation data; wherein
the higher temperature is based on a fewer than average number of light-emitting diodes in the first element set based on absence of operable light-emitting diode at a position in the emission area, and
the compensator adjusts a current density of the display device, based on the compensation data, for improvement of a luminous efficiency of the display device.
