Abstract
A display device includes a display pixel unit and a signal processing unit. The display pixel unit includes a plurality of pixels arranged in a horizontal direction and a vertical direction. The signal processing unit determines a correction value corresponding to a target pixel based on differences between gradation data of the target pixel and gradation data of peripheral pixels disposed in the horizontal direction, the vertical direction, and an oblique direction with respect to the target pixel, respectively, among the plurality of pixels, increases or decreases a pixel value of the target pixel based on the correction value, and corrects the gradation data of the target pixel to reduce the differences.
Claims9
A liquid crystal display device comprising:
- a display pixel unit in which a plurality of pixels are arranged in a horizontal direction and a vertical direction;
- and
- a signal processing unit configured to set a correction coefficient for each direction including the horizontal direction, the vertical direction, and an oblique direction with respect to a target pixel, corresponding to differences between gradation data of the target pixel and gradation data of peripheral pixels disposed in the horizontal direction, the vertical direction, and the oblique direction with respect to the target pixel, respectively, among the plurality of pixels, and to determine a correction value to be added to or to be subtracted from the target pixel by multiplying the differences by the correction coefficient for each direction.
A display method for displaying an image on a liquid crystal display device, the liquid crystal display device including a plurality of pixels arranged in a horizontal direction and a vertical direction, the display method comprising:
- setting a correction coefficient for each direction including the horizontal direction, the vertical direction, and an oblique direction with respect to a target pixel, corresponding to differences between gradation data of the target pixel and gradation data of peripheral pixels disposed in the horizontal direction, the vertical direction, and the oblique direction with respect to the target pixel, respectively, among the plurality of pixels;
- and
- determining a correction value to be added to or to be subtracted from the target pixel by multiplying the differences by the correction coefficient for each direction.
A liquid crystal display device comprising:
- a display pixel unit in which a plurality of pixels are arranged in a horizontal direction and a vertical direction;
- and
- a signal processing unit configured to set a correction coefficient for each direction including the horizontal direction, the vertical direction, and an oblique direction with respect to a target pixel, corresponding to first differences between gradation data of the target pixel and gradation data of first peripheral pixels adjacent to the target pixel and second differences between the gradation data of the target pixel and gradation data of second peripheral pixels adjacent to the first peripheral pixels, among the plurality of pixels, and to determine a correction value to be added to or to be subtracted from the target pixel by multiplying the first and second differences by the correction coefficient for each direction.
