Abstract:
1. A matrix addressing method for driving pixels arranged over a display area by signals supplied to row electrodes and column electrodes arranged to cross one another, the method comprising the following steps of: generating rich-gray-scale pixel information signals in a predetermined number of levels of gray scale in accordance with original pixel information signals; generating poor-gray-scale pixel information signals in a smaller number of levels of gray scale than the predetermined number of levels of gray scale in according with original pixel information signals, wherein the poor-gray-scale pixel information signals are obtained by performing a dithering processing on the original pixel information signals; and discretely mixing rich-gray-scale pixels driven by the rich-gray-scale pixel information signals and poor-gray-scale pixels driven by the poor-gray-scale pixel information signals to coexist in at least a part of the display area in a predetermined mixing pattern to display the same image object in a predetermined mode, wherein the poor-gray-scale pixels are driven by the poor-gray-scale pixel information signals at a lower frequency than that of the rich-gray-scale pixels, wherein gamma correction characteristics are applied to the rich-gray-scale pixel information signals, and wherein the gamma correction characteristics are variable in according with a spatial arrangement manner in the display area of the poor-gray-scale pixels driven by the poor-gray-scale pixel information signals, an input instruction or other setting.
