Image display device and image display method

An image display method using:

• a backlight including a plurality of light-emitting regions;
• and
• a display panel coupled to the backlight and including a plurality of pixels, the method comprising, with respect to input image data:
• generating luminance setting data that sets a luminance value for each of the light-emitting regions of the backlight, based on:
• the input image data;
• and
• data of positional correction coefficients that are set with respect to the plurality of light-emitting regions, respectively, for compensating luminance non-uniformity;
• generating luminance estimation data that indicates an estimated luminance value of the backlight operated in accordance with the luminance setting data, with respect to each of the plurality of light-emitting regions, based on:
• the luminance setting data,
• luminance profile data indicating a luminance distribution of light emitted by a single light-emitting region of the backlight onto the single light-emitting region and adjacent light-emitting regions thereof, and
• the data of positional correction coefficients;
• generating gradation setting data that sets a gradation value for each of the pixels of the display panel, based on:
• the input image data, and
• the luminance estimation data;
• and
• controlling the backlight to operate based on the luminance setting data and the display panel to operate based on the gradation setting data to display an image corresponding to the input image data.
