Display device
A display device includes: a target pixel; observation target pixels located adjacent to the target pixel; and a grayscale corrector for converting an input grayscale value corresponding to the target pixel with reference to observation target grayscale values corresponding to the observation target pixels. The grayscale corrector includes: a light emitting pixel counter for providing a number of light emitting pixels by counting a number of observation target pixels that exceeds a reference value; and a grayscale converter for providing a converted grayscale value by converting the input grayscale value, based on the number of light emitting pixels.
1. A display device comprising:
a first pixel having a first emission area; and
second pixels located adjacent to the first pixel and having a second emission area smaller than the first emission area,
wherein, when the first pixel and all of the second pixels emit light, the first pixel emits light of a first luminance in response to a first input grayscale value, and
wherein, when the first pixel emits light but none of the second pixels emit light, the first pixel emits light of a second luminance higher than the first luminance in response to the first input grayscale value.
2. The display device of claim 1 ,
wherein, when the first pixel emits light and only one of the second pixels emits light, the first pixel emits light of a third luminance between the first luminance and the second luminance in response to the first input grayscale value.
3. The display device of claim 2 ,
wherein, when the first pixel emits light and only two of the second pixels emit light, the first pixel emits light of a fourth luminance between the first luminance and the third luminance in response to the first input grayscale value.
4. The display device of claim 3 ,
wherein, when the first pixel emits light and only three of the second pixels emit light, the first pixel emits light of a fifth luminance between the first luminance and the fourth luminance in response to the first input grayscale value.
5. The display device of claim 4 ,
wherein the first pixel emits light of a first color, and
wherein the second pixels emit light of a second color different from the first color.
6. The display device of claim 5 ,
wherein the first color is red.
7. The display device of claim 6 ,
wherein the second color is green.
8. The display device of claim 1 ,
wherein the first pixel is connected to a first data line different from second and third data lines to which the second pixels are connected.
9. The display device of claim 8 ,
wherein the first pixel is connected to a first scan line different from second and third scan lines to which the second pixels are connected.
10. The display device of claim 9 ,
wherein the first data line is located between the second and third data lines, and
wherein the first scan line is located between the second and third scan lines.
11. A display device comprising:
a first pixel having a first emission area; and
second pixels located adjacent to the first pixel and having a second emission area smaller than the first emission area,
wherein, when the first pixel and all of the second pixels emit light, the first pixel emits light of a first luminance in response to a first input grayscale value, and
wherein, when the first pixel emits light but none of the second pixels emit light, the first pixel emits light of a second luminance lower than the first luminance in response to the first input grayscale value.
12. The display device of claim 11 ,
wherein, when the first pixel emits light and only one of the second pixels emits light, the first pixel emits light of a third luminance between the first luminance and the second luminance in response to the first input grayscale value.
13. The display device of claim 12 ,
wherein, when the first pixel emits light and only two of the second pixels emit light, the first pixel emits light of a fourth luminance between the first luminance and the third luminance in response to the first input grayscale value.
14. The display device of claim 13 ,
wherein, when the first pixel emits light and only three of the second pixels emit light, the first pixel emits light of a fifth luminance between the first luminance and the fourth luminance in response to the first input grayscale value.
15. The display device of claim 14 ,
wherein the first pixel emits light of a first color, and
wherein the second pixels emit light of a second color different from the first color.
16. The display device of claim 15 ,
wherein the first color is blue.
17. The display device of claim 16 ,
wherein the second color is green.
18. The display device of claim 11 ,
wherein the first pixel is connected to a first data line different from second and third data lines to which the second pixels are connected.
19. The display device of claim 18 ,
wherein the first pixel is connected to a first scan line different from second and third scan lines to which the second pixels are connected.
20. The display device of claim 19 ,
wherein the first data line is located between the second and third data lines, and
wherein the first scan line is located between the second and third scan lines.
