<P>PROBLEM TO BE SOLVED: To enhance image quality in visual appreciation by utilizing a color and a position of a sub-pixel corresponding to a white color in a case where a color display is performed by sub-pixels of four colors. <P>SOLUTION: A display device displays an image by sub-pixels of four colors of R (red), G (green), B (blue) and W (white). A sub-pixel G is positioned in a diagonal direction with respect to a sub-pixel W. Further, a sub-pixel R is adjacent to the sub-pixel W in an X direction, lateral direction in a FIG., and a sub-pixel B is adjacent to the sub-pixel W in a Y direction, longitudinal direction in the FIG. In such configuration, high frequency components of an image signal of R in the Y direction are restricted and high frequency components of an image signal of B in the X direction are restricted. Furthermore, an image signal of G and an image signal of W regard individual sub-pixels as sub-pixels of the same color and perform the same band restriction to the individual sub-pixels. <P>COPYRIGHT: (C)2013,JPO&INPIT |
