Patent ID: 8830255

Claim:
An active matrix display device comprising: regions each including an arrangement of first pixels each changing, in order to display a gray level for a period, its luminance in a sequence repeating a luminance change pattern of A frames (where A is an even number) through a cycle of the A frames, wherein: the sequence includes, in each of the regions, a plurality of sequences that are shifted from one another in the luminance change pattern along a time axis direction and that are defined for said each of the regions, one of the plurality of sequences being allotted to each of the first pixels in said each of the regions; for said each of the first pixels, each jth frame corresponding to at least one integer j (where 1≦j≦A) for each of the A frames has, in a corresponding sequence, a luminance having a first mean value that is different from a second mean value of a luminance, in the corresponding sequence, of a frame occurring A/2 frames after the jth frame; the first pixels are provided in correspondence with each of data colors each as a constituent element of a display color, the data colors including an achromatic color; and assuming that a row direction and a column direction are each an array direction, said each of the regions includes an arrangement pattern including, for each of at least one array direction and for each of the data colors, X first pixels arranged next to one another in the array direction, the arrangement pattern being repeated in the array direction, the X being represented by X=A/ 2 +A·Q, where Q is an integer of 0 or greater and is defined for said each of the regions.
