1. A display system comprising:
a display panel with a display area;
a lighting device located facing one side of the display area and emitting light to the display panel;
a correction coefficient generating circuit receiving a plurality of image data including first image data and second image data, generating a first correction coefficient based on a brightness of the first image data and generating a second correction coefficient based on a brightness of the second image data, and the first image data corresponding to a first image and the second image data corresponding to a second image adjacent to the first image and located on the opposite side of the lighting device to the first image;
a multiplication circuit receiving at least the first image data and the second image data, receiving at least the first correction coefficient and the second correction coefficient from the correction coefficient generating circuit, generating first corrected image data using the first image data and the first correction coefficient, and generating second corrected image data using the second image data and the second correction coefficient;
a display drive control unit receiving the first corrected image data and the second corrected image data from the multiplication circuit, and transmitting the first corrected image data and the second corrected image data to the display panel; and
a display control unit; wherein
the display control unit executes a first scan in which the image displayed on the display panel is scanned parallel to or substantially parallel to the direction in which the light is incident on the display panel, and executes a second scan in which the image is scanned perpendicularly or substantially perpendicular to the direction in which the light is incident on the display panel, and
the correction coefficient generation circuit generates the first correction coefficient using the first image data corresponding to the first image scanned in the first scan and the second scan, and generates the second correction coefficient using the second image data corresponding to the second image scanned in the first scan and the second scan.
