Abstract
A display device includes: a first controller that outputs an output image signal having the same resolution as that of pixels to an image display panel; and a second controller that transmits an input image signal to the first controller, generates second luminance distribution data divided into regions at a second density lower than a first density equal to the resolution, and transmits the second luminance distribution data to the first controller. The second controller generates first luminance distribution data divided into regions at a third density lower than the second density, controls an illuminator based on the first luminance distribution data, and generates the second luminance distribution data by applying a polynomial interpolation to the first luminance distribution data. The first controller generates third luminance distribution data having the resolution, and generates the output image signal by adjusting the input image signal based on the third luminance distribution data.
