1. A display apparatus, comprising:
a display panel configured to display an image;
an image analysis portion configured to calculate a crosstalk level when a crosstalk pattern exists in the image; and
a dithering portion configured to set a dithering bit corresponding to the crosstalk level, and perform a time dithering processing with the dithering bit on input image data located in a region where a crosstalk occurs by the crosstalk pattern, to generate compensation image data,
wherein the time dithering processing is performed to lower a gray level of the region where the crosstalk occurs when the crosstalk level has a positive value, and is performed to increase the gray level of the region where the crosstalk occurs when the crosstalk level has a negative value.
