Display device and driving method thereof

A display device comprising:

• an image signal processor that is supplied with original image signals for various frames and outputs a first image signal for the respective frames and a second image signal for an interpolation frame inserted between a previous frame and a current frame among the respective frames;
• a data driver that provides a data signal based on the first image signal or the second image signal;
• and
• a display panel that displays an image in response to the data signal, wherein the first image signal is a signal obtained by correcting levels of the original image signals and the second image signal is a signal obtained by correcting a level of an interpolation signal generated using the original image signals for the previous frame and the current frame, and
• wherein the image signal processor comprises:
• a first correction unit that is supplied with the original image signals and provides the first image signal obtained by correcting levels of the original image signals;
• an image interpolator that generates the interpolation signal using the original image signals for the previous frame and the current frame;
• and
• a second correction unit that is supplied with the interpolation signal and provides the second image signal obtained by correcting a level of the interpolation signal.

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

• receiving original image signals for various frames and generating an interpolation signal used to display images corresponding to interpolation frames;
• displaying images corresponding to a first gamma curve corrected based on an original gamma curve in the respective various frames;
• and
• displaying images corresponding to a second gamma curve corrected based on the original gamma curve in the interpolation frames,
• wherein the image signal processor comprises:
• a first correction unit that is supplied with the original image signals and provides the first image signal obtained by correcting levels of the original image signals;
• an image interpolator that generates the interpolation signal using the original image signals for the previous frame and the current frame;
• and
• a second correction unit that is supplied with the interpolation signal and provides the second image signal obtained by correcting a level of the interpolation signal.
