An image display method includes generating luminance data, correcting the luminance data, generating gradation setting data, and controlling a backlight to operate based on the luminance setting data and a liquid crystal panel to operate based on the gradation setting data. The luminance data indicates a luminance value for each light-emitting region of the backlight and is generated based on a maximum gradation value among gradation values of image pixels of an input image that correspond to the light-emitting region. The luminance data is corrected such that, with respect to each light-emitting region, the luminance value is within a predetermined range below a maximum value among the luminance values of neighboring light-emitting regions, and luminance setting data is generated therefrom. The gradation setting data sets a gradation value of each pixel of the liquid crystal panel, and generated based on the input image and the luminance setting data.

Luminance control of backlight in display of image

In accordance with an embodiment of the present invention, the light emitting device includes a first light emitting module and a plurality of second light emitting modules. The first light emitting module includes a first side along a first direction, and a second side along the first direction. The direction from the first side to the second side is along a second direction that intersects with the first direction. The plurality of second light emitting modules are lined up along the second direction. The direction from a first emission region which includes the plurality of second light emitting modules to the first light emitting module is along the first direction. The first emission region includes a third side along the first direction and a fourth side along the first direction. The direction from the third side to the first side is along the first direction. The direction from the fourth side to the second side is along the first direction.
