Display device and method of driving the same

A method of driving a display device, the method comprising:

• sub-sampling an original image signal;
• generating a sub-image signal;
• generating a sub-interpolated image signal from the sub-image signal;
• generating an interpolated image signal by realigning the sub-interpolated image signal;
• and
• displaying a display image based on the interpolated image signal,
• wherein when two successive frames of the original image signal are dynamic, the sub-sampling the original image signal, the generating the sub-interpolated image signal and the generating the interpolated image signal by realigning the sub-interpolated image signal are performed on the two dynamic successive frames.

A method of driving a display device, the method comprising:

• sub-sampling an original image signal;
• generating a sub-image signal;
• generating a sub-interpolated image signal from the sub-image signal;
• generating an interpolated image signal by realigning the sub-interpolated image signal;
• and
• displaying a display image based on the interpolated image signal,
• wherein when two successive frames of the original image signal are static, the original image signal corresponding to a previous frame of the two successive frames is used as the interpolated image signal for the two static successive frames.

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,
• wherein the sub-sampler sub-samples the original image and the motion interpolator generates the sub-interpolated image signal by dividing the original image signal into even data and odd data.
