Abstract: A data processing apparatus includes a diagonal detector, a first processor, and a second processor. The diagonal detector may determine whether a red-blue data set includes data for controlling a display device to display any diagonal line, the display device including subpixels arranged in first-type lines and second-type lines that are alternately disposed, the red-blue data set including 9 data values that correspond to 9 subpixels among the subpixels, the 9 subpixels forming a 3-by-3 array that includes a center subpixel, the 9 data values including a center data value that corresponds to the center subpixel. The first/second processor may process the center data value using a first/second coefficient to produce a first/second value that corresponds to the center subpixel if the center subpixel is in the first-type/second-type lines.

Abstract: A display device includes dots and a grayscale correction unit. Each dot among the dots includes a first pixel of a first color, a second pixel of a second color, and a third pixel of a third color. The grayscale correction unit is configured to generate corrected grayscale values for a target dot via application of weights to grayscale values of the target dot and grayscale values of neighboring dots of the target dot among the dots. The grayscale correction unit is configured to determine the weights based on the grayscale values of the target dot.

Abstract: A display driver includes a video data conversion unit, a data compression unit, a memory unit, and a data restoration unit. The video data conversion unit converts first video data that includes RGB data to second video data that includes pentile data. The data compression unit compresses at least a portion of the second video data. The memory unit stores at least the compressed second video data. The data restoration unit restores the compressed second video data.

Abstract: A method of determining pixel luminance includes determining a smoothing reference line between a display region and a non-display region in a display panel, determining a boundary pixel, through which the smoothing reference line passes, among pixels included in the display region, dividing the boundary pixel into a first pixel region in the display region and a second pixel region in the non-display region based on the smoothing reference line, calculating a smoothing rate corresponding to a ratio of an area of the first pixel region to a total area of the boundary pixel, and determining dimming luminance of the boundary pixel based on the smoothing rate.
