1. A display device, comprising:

  • a plurality of pixels, each of the plurality of pixels including a light emitter and a driver, the driver supplying current to the light emitter;

    a plurality of data lines, each of the plurality of data lines supplying a voltage signal to one of the plurality of pixels, the voltage signal corresponding to a voltage to be supplied to a gate of the driver included in the corresponding one of the plurality of pixels;

    a data line driver that supplies the voltage signal to each of the plurality of data lines;

    a first memory configured to store, for each of the plurality of pixels, a luminance gain, the luminance gain being used for adjusting a luminance corresponding to a video signal for each of the plurality of pixels to a standard luminance value;

    a second memory configured to store conversion information representing a representative conversion curve, the representative conversion curve representing a relationship between a common voltage and a common luminance, the relationship being common to the plurality of pixels;

    a corrector configured to convert, for each of the plurality of pixels, the luminance corresponding to the video signal into a corresponding standard luminance value, based on a corresponding luminance gain stored in the first memory; and

    a converter configured to convert, for each of the plurality of pixels, the corresponding standard luminance value into a corresponding voltage signal, based on the conversion information stored in the second memory.
