Luminance control of backlight in display of image

A display comprising:

• a backlight including a plurality of light-emitting regions that are configured in a matrix form and independently operable;
• a liquid crystal panel coupled to the backlight panel and including a plurality of pixels;
• and
• a controller configured to:
• generate luminance data that indicates a luminance value for each of the light-emitting regions of the backlight based on a maximum gradation value among gradation values of image pixels of an input image that correspond to the light-emitting region;
• perform correction of the luminance data such that, with respect to each of the light-emitting regions, the luminance value is within a predetermined range below a maximum luminance value among the luminance values of neighboring light-emitting regions thereof, to generate luminance setting data;
• generating gradation setting data that sets a gradation value of each of the pixels of the liquid crystal panel for the input image, based on the input image and the luminance setting data;
• and
• control the backlight to operate based on the luminance setting data and the liquid crystal panel to operate based on the gradation setting data to display an image corresponding to the input image.
