Display device having edge determiner and subpixel renderer and method of driving the same

A display device comprising:

• a display panel comprising pixels, each pixel among the pixels comprising sub-pixels;
• and
• an image processor configured to process image data for image display via the display panel,
• wherein 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 such that a pixel in the even-numbered pixel column and one pixel row of the display panel is shifted from a pixel in the odd-numbered pixel column and the pixel row in a vertical direction, and
• wherein the image processor comprises:
• an edge determiner configured to determine an edge from the image data;
• and
• a sub-pixel renderer 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.
