ABSTRACT:
Row electrodes of a display panel are divided into first row electrodes and second row electrodes. A field for the first row electrodes is divided into a plurality of sub-fields each of which has a time length different from other sub-fields to be allocated with a weight. A field for the second row electrodes is divided into a plurality of sub-fields which are the same as the sub-fields of the first row electrodes in time length. Scanning of the row electrodes starts at an exciting operation of a first row and ends at an erasing operation of a last row. Pixel data are extracted from an input signal, each of the pixel data includes luminance data which designates at least one corresponding sub-field. Scanning of the first row electrodes and the second row electrodes is performed in sequence in accordance with the arrangement of sub-fields of both the row groups.
