Abstract:
1. A method of driving an image display apparatus, comprising: providing an image display apparatus including (a) an image display panel with P×Q pixels arrayed in a two-dimensional matrix, the P pixels arrayed in a first direction and the Q pixels arrayed in a second direction; and (b) a signal processing section, the two-dimensional matrix having pixel groups each comprised of a first pixel and a second pixel along the first direction, for each group, the first pixel consisting of a first subpixel for displaying a first primary color, a second subpixel for displaying a second primary color and a third subpixel for displaying a third primary color and, for each group, the second pixel consisting of a first subpixel for displaying the first primary color, a second subpixel for displaying the second primary color and a fourth subpixel for displaying a fourth color, calculating a first subpixel output signal to the first pixel based at least on a first subpixel input signal to the first pixel and outputting the first subpixel output signal to the first subpixel of the first pixel; calculating a second subpixel output signal to the first pixel based at least on a second subpixel input signal to the first pixel and outputting the second subpixel output signal to the second subpixel of the first pixel; calculating a first subpixel output signal to the second pixel based at least on a first subpixel input signal to the second pixel and outputting the first subpixel output signal to the first subpixel of the second pixel; calculating a second subpixel output signal to the second pixel based on a second subpixel input signal to the second pixel and outputting the second subpixel output signal to the second subpixel of the second pixel; calculating a third subpixel output signal to a (p,q)th first pixel, where p is 1, 2 . . . , P−1 and q is 1, 2 . . . , Q when the pixels are counted along the first direction, first pixel based on a third subpixel input signal to the (p,q)th first pixel and a third subpixel input signal to the (p,q)th second signal, and outputting the third subpixel output signal to the third subpixel of the (p,q)th first pixel; and calculating a fourth subpixel output signal to the (p,q)th second pixel by taking an arithmetic mean between the third subpixel input signal to the (p,q)th second pixel and the third subpixel input signal to the (p+1,q)th first pixel, and outputting the fourth subpixel output signal to the fourth subpixel of the (p,q)th second pixel.
