1. A display device comprising a rectangular pixel unit, the rectangular pixel unit comprising:
a first dot including a first shared pixel and a first dedicated pixel, the first dot disposed at a first edge of the rectangular pixel unit;
a second dot disposed closest to the first dot in a first direction and including a second shared pixel and a second dedicated pixel;
a third dot disposed in the first direction from the second dot and including a third shared pixel and a third dedicated pixel; and
a first dummy dot disposed closest to the third dot in the first direction and including a first dummy pixel, the first dummy dot disposed at a second edge of the rectangular pixel unit,
wherein:
the first shared pixel and the second shared pixel are configured to emit light having different colors;
the first dedicated pixel, the second dedicated pixel, and the third dedicated pixel are configured to emit light having the same color;
the third shared pixel and the first dummy pixel are configured to emit light having different colors;
a light-emitting area of the first shared pixel is smaller than a light-emitting area of the second shared pixel;
a light-emitting area of the first dummy pixel is smaller than a light-emitting area of the third shared pixel;
the second shared pixel is connected to, among a plurality of data lines, only a single data line;
the first dummy pixel is configured to display an input grayscale value provided to the third dot; and
a first proportion of the input grayscale value of the third dot applied to an output grayscale value of the first dummy pixel is greater than a second proportion of an input grayscale value of the first dot applied to an output grayscale value of the second shared pixel.
