Display device and method of driving the same

A method of driving a display device including a display panel having display blocks, each of the display blocks including k groups of pixels, the method comprising:

• sub-sampling an original image signal which corresponds to one group of the k groups of pixels included in one of the display blocks;
• extracting a sub-image signal from the original image signal which is sub-sampled;
• generating a sub-interpolated image signal from the sub-image signal;
• generating an interpolated image signal corresponding to unsampled pixels of the k groups of pixels included in the one of the display blocks using the sub-interpolated image signal;
• generating an interpolated frame based on the interpolated image signal;
• and
• displaying a display image having the interpolated frame, wherein
• the display image is displayed on the display panel,
• the sub-image signal corresponds to a sub-sample image,
• the sub-sample image includes images, each sampled from k images into which a portion of the display image, displayed on display blocks, and
• k is a natural number greater than or equal to two.

A display device comprising:

• a sub-sampler which sub-samples an original image signal and generates a sub-image signal;
• a motion interpolator which generates a sub-interpolated image signal from the sub-image signal;
• an image realigner which realigns the sub-interpolated image signal and outputs an interpolated image signal;
• and
• a display panel which displays a display image having an interpolated frame corresponding to the interpolated image signal.
