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.

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: An image processor includes a scaling unit configured to output converted data by resizing first image data; and a rendering unit configured to receive second image data, to output rendering data by rendering the second image data, and to calculate a target rendering data value based on data values corresponding to a first block of M*N among the second image data, where each of M and N is an integer greater than or equal to 2. Here, the second image data is the converted data, or the first image data is the rendering data.

Abstract: A display device includes a display panel, a plurality of readout circuits, and a deviation corrector. The display panel includes a plurality of pixels. The readout integrated circuits perform a readout operation of detected values including degradation information of the pixels, via readout lines connected to the pixels, when a degradation detecting operation is performed. The deviation corrector calculates weighted values to correct operating deviation of the readout integrated circuits based on an average of initial values. The deviation corrector generates corrected image data to correct input image data based on the weighted values. The initial values correspond to the detected values output from the readout integrated circuits when the display panel is in an initial state in which the pixels are non-degraded.
