Abstract
A display device includes a pixel component including a first pixel area in which pixels are disposed at a first density, and a second pixel area in which the pixels are disposed at a second density less than the first density, and a grayscale compensator which converts input grayscale values for the first pixel area to output grayscale values within a first grayscale range, and converts the input grayscale values for the second pixel area to the output grayscale values within a second grayscale range. An upper limit of the second grayscale range is greater than an upper limit of the first grayscale range.
Claims20
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.
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.
