Patent ID: 6954191

Claim:
A liquid crystal display apparatus capable of color-displaying comprising: a crystal panel having, in each main pixel unit, a red outputting subpixel, a green outputting subpixel, a blue outputting subpixel, and a luminance-intensifying subpixel, and a decoder that is configured to provide a digital value for driving the luminance-intensifying subpixel by carrying out a predetermined calculation processing using digital values respectively for a red inputting pixel, a green inputting pixel, and a blue inputting pixel which are obtained from an input image, wherein: the liquid crystal displaying apparatus driving the luminance-intensifying subpixel, the red outputting subpixel, the green outputting subpixel and the blue outputting subpixel by using the digital value for driving the luminance-intensifying subpixel obtained by the decoder and the digital values of the red, green and blue inputting subpixels, and the predetermined calculation processing obtains the digital value for driving the luminance-intensifying subpixel by a function of W=f(Ymin, Ymax) where the digital value of the luminance-intensifying pixel is defined as W, and a minimum value and a maximum value of the digital values of the red inputting subpixel, the green inputting subpixel and the blue inputting subpixel are respectively defined as Ymin and Ymax, and the function f(Ymin, Ymax) provides an output value that is dependent upon both Ymin and Ymax.
