Abstract: An image display method using an image display device is provided. The method includes performing a first operation to cause light to be emitted from light-emitting regions of a backlight at respective intensity in accordance with frame image data, sequentially with respect to each of first areas of the backlight, and performing a second operation to apply voltages to pixels of a liquid crystal panel at respective levels in accordance with the frame image data, sequentially with respect to each of second areas of the liquid crystal panel.

Abstract: An image display method includes generating luminance data, applying a special filter to the luminance data, generating luminance setting data, generating gradation setting data, and controlling a backlight based on the luminance setting data and a liquid crystal panel based on the gradation setting data. The luminance data indicates a luminance value for each of 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. The special filter is applied such that, with respect to each light-emitting region, a difference of the luminance value thereof from the luminance values of neighboring light-emitting regions decreases, and the luminance setting data is generated therefrom. The gradation setting data sets a gradation value of each pixel of the liquid crystal panel, and is generated based on the input image and the luminance setting data.

Abstract: In an image display method, a backlight is divided into first areas in a first direction. Each of the first areas includes light-emitting regions. A liquid crystal panel is divided into second areas in the first direction. In the method, a first operation to cause light to be emitted from the light-emitting regions at respective intensity in accordance with frame image data is performed sequentially with respect to each of the first areas. Further, a second operation to apply voltages to the pixels at respective levels in accordance with the frame image data is performed sequentially with respect to each of the second areas. A timing at which the first operation with respect to each of the first areas is started is delayed from a timing at which the second operation with respect to a corresponding one of the second areas is started by a predetermined interval.

Abstract: 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.
