Patent number: 9202422Abstract: A pixel of a liquid crystal panel is constituted by three subpixels. When the gradation of the pixel can be represented by only the subpixel, with setting the gradations of the subpixels to their minimum gradations, the gradation of the subpixel is determined. When the gradation of the pixel is represented by the subpixels, with setting the gradation of the subpixel to its maximum gradation and setting the gradation of the subpixel to its minimum gradation, the gradation of the subpixel is determined so that the ratio of the transmittance of the subpixel to the transmittance of the pixel is less than a limit value. When the gradation of the subpixel cannot be determined to satisfy a condition, with setting the gradation of the subpixel to its minimum gradation, the gradations of the subpixels are determined to obtain a gradation higher than or equal to the gradation of the pixel.Type: GrantFiled: January 6, 2012Date of Patent: December 1, 2015Assignee: SHARP KABUSHIKI KAISHAInventor: Katsuya Ogawa
