Display apparatus correcting afterimage area

A display apparatus, comprising:

• a display panel including a plurality of pixels;
• a controller configured to:
• receive an image data;
• detect a first data of an afterimage area from the image data by accumulating a data difference for each pixel between adjacent frames by the image data;
• adjust a saturation correction value based on the first data of the afterimage area;
• correct the first data of the afterimage area to a second data based on the saturation correction value;
• and
• supply an output data including the second data;
• and
• a circuit part configured to provide data signals to the plurality of pixels based on the output data supplied from the controller,
• wherein when the controller corrects the first data of the afterimage area to a second data based on the saturation correction value, the controller reduces a saturation of the first data so that a color difference value between the first data and the second data is included in a predetermined reference color difference range being from about 0.004 to about 0.02,
• wherein the first data includes a first red data, a first green data, and a first blue data, wherein the second data includes a second red data, a second green data, and a second blue data,
• wherein a maximum value among the second red data, the second green data, and the second blue data is less than a maximum value among the first red data, the first green data, and the first blue data, and
• wherein a minimum value among the second red data, the second green data, and the second blue data is greater than a minimum value among the first red data, the first green data, and the first blue data.
