Abstract: A display device includes a display panel and an image processor. The display panel includes pixels, each pixel among the pixels including sub-pixels. The image processor is configured to process image data for image display via the display panel. An arrangement of sub-pixels of a pixel in an odd-numbered pixel column of the display panel is different from an arrangement of sub-pixels of a pixel in an even-numbered pixel column of the display panel. The image processor includes an edge determiner and a sub-pixel renderer. The edge determiner is configured to determine an edge from the image data. The sub-pixel renderer is configured to perform sub-pixel rendering on pixel data about sub-pixels configured to display a same color in adjacent pixels in the odd-numbered pixel column or the even-numbered pixel column located at the edge.

Abstract: A pixel includes a light-emitting element, a driving switching element and a noise switching element. The driving switching element applies a driving current to the light-emitting element. The noise switching element outputs a noise signal having a noise frequency to an input electrode of the driving switching element in response to a noise control signal. The noise frequency is equal to or greater than a driving frequency of the pixel. The noise signal having a periodicity is applied to the input electrode of the driving switching element of the pixel.
