    Abstract: A display device with reduced dynamic false contouring effect is disclosed. In one aspect, the device includes a display unit including a plurality of pixels and a timing controller. The timing controller is configured to determine a grayscale value of an image frame based on a grayscale distribution of the image frame. The controller is further configured to determine an arrangement of sub-frames as a driving mode based on the determined grayscale.

    Abstract: A display device includes a degradation compensator, a controller, a data driver, and a display panel. The degradation compensator generates a first fitting function and a second fitting function based on image data, generates a compensation function through a harmonic mean of the first and second fitting functions, and generates a compensation value based on the compensation function. The controller receives the compensation value, and generates input image data to which the compensation value is applied. The data driver receives the input image data to which the compensation value is applied, and converts the input image data into a data voltage. The display panel includes pixels, in which each of the pixels includes a pixel circuit which receives the data voltage and a light-emitting element electrically connected to the pixel circuit.

    Abstract: In a method of generating compensation data for a display device, first color, second color, and third color compensation value sets may be obtained by capturing first color, second color, and third color images displayed by the display device, respectively, white, first color, second color, and third color loading luminances may be obtained by capturing white, first color, second color, and third color loading patterns displayed by the display device, respectively, first color, second color, and third color scale factors may be calculated by dividing a luminance decrease ratio of the white loading luminance by luminance decrease ratios of the first color, second color, and third color loading luminances, respectively, and the first color, second color, and third color compensation value sets and the first color, second color, and third color scale factors may be stored in the display device.

    Abstract: A display device includes a first display region, a second display region, a first lens, and a second lens. The first display region includes a first pixel subset and may display a first image. The first image includes a first sub-image corresponding to the first pixel subset and smaller than the first image. The second display region neighbors the first display region, includes a second pixel subset, and may display a second image. The second image includes a second sub-image corresponding to the second pixel subset and smaller than the second image. The second pixel subset is not identical to the first pixel subset. The first lens may show the first sub-image without providing the entire first image. The second lens may show the second sub-image without providing the entire second image when the first lens shows the first sub-image.
