Abstract:
The purpose of the present invention is to improve the display quality of a display device in which a plurality of display panels are disposed in a stack. The present invention provides a display device for displaying an image, said display device comprising a light source, a plurality of display panels disposed in a stack, a wide area smoothing unit, a narrow area smoothing unit, and a blending unit, wherein: the plurality of display panels comprise a first panel and a second panel disposed between the light source and the first panel; the wide area smoothing unit performs a smoothing process on brightness information values of a target area including a target pixel and pixels surrounding the same, and outputs a wide area smoothed value; the narrow area smoothing unit performs a smoothing process on brightness information values of a target area that includes a target pixel and pixels surrounding the same and is smaller than the target area of the wide area smoothing unit, and outputs a narrow area smoothed value; the blending unit outputs a blended value obtained by blending the wide area smoothed value and the narrow area smoothed value using a prescribed blend ratio; the second panel displays an image generated using the blended value; and the brightness information values are generated using image brightness.
