Abstract:
1. A display device comprising: an image processing unit which performs image processing of input RGB image data, a display panel which is driven by output RGB image data from said image processing unit, a backlight which illuminates said display panel, and a backlight control unit which controls said backlight on the basis of an image adjustment parameter from said image processing unit; wherein said image processing unit is configured to convert the input RGB image data into first YUV image data comprising a chroma value and a luminance value, and to generate the image adjustment parameter based on the chroma value of the first YUV image data, wherein said image processing unit includes an image expansion unit which directly receives the input RGB image data and generates the output RGB image data by using the image adjustment parameter, and wherein the image expansion unit and the backlight control unit are interlocked with each other so that luminance of the backlight is adjusted by the backlight control unit in accordance with the image adjustment parameter.
