1. A display device comprising:
a pixel component including:
a first pixel area in which first pixels are disposed at a first density, the first density defined by a proportion of a pixel disposition area of the first pixels per unit area, and
a second pixel area in which second pixels are disposed at a second density lower than the first density, the second density defined by a proportion of a pixel disposition area of the second pixels per unit area; and
a grayscale compensator which converts input grayscale values for the first pixel area to output grayscale values within a first grayscale range, converts the input grayscale values for the second pixel area to the output grayscale values within a second grayscale range,
wherein an upper limit of the second grayscale range is greater than an upper limit of the first grayscale range.
 
11. A method of driving a display device comprising a pixel component including a first pixel area in which first pixels are disposed at a first density, and a second pixel area in which second pixels are disposed at a second density lower than the first density, the method comprising:
converting input grayscale values for the first pixel area to output grayscale values within a first grayscale range; and
converting the input grayscale values for the second pixel area to the output grayscale values within a second grayscale range,
wherein an upper limit of the second grayscale range is greater than an upper limit of the first grayscale range, and
wherein the first density is defined by a proportion of a pixel disposition area of the first pixels per unit area, and the second density is defined by a proportion of a pixel disposition area of the second pixels per unit area.
