Classification: CPC G | IPC G

Claim 9:
10. A display device comprising:
a display panel including a plurality of pixels configured to display an image;
an afterimage compensator configured to detect a logo image and generate blurring image data for blurring the logo image;
a scan driver configured to provide a scan signal to the display panel; and
a data driver configured to provide the display panel with a data signal corresponding to the blurring image data and input image data,
wherein the afterimage compensator includes:
a logo detector configured to detect a logo area including the logo image and a logo background image at a periphery of the logo image, based on the input image data;
a blurring determiner configured to determine a blurring area including the logo image and a portion of the logo background image adjacent to the logo image, based on a preliminary blurring map; and
an image corrector configured to blur input image data of pixels included in the blurring area, except input image data of pixels outside the blurring area,
wherein the blurring determiner calculates a logo map including binary values, based on the logo image and the logo background image, and then calculates the preliminary blurring map including blurring candidate values of binary values and non-binary values, based on the logo map, and
wherein the blurring area is smaller than the preliminary blurring map such that the blurring area includes pixels of which the blurring candidate values are larger than a preset blurring threshold value establishing a threshold value for blurring the logo image.
