Patent ID: 7042429

Claim:
A method of driving a display device, said display device comprising: a plurality of gate signal lines extending in one direction and arranged in another direction intersecting said one direction on a substrate; a plurality of drain signal lines arranged to intersect said plurality of gate signal lines; a plurality of pixels each surrounded by two adjacent ones of said plurality of gate signal lines and two adjacent ones of said plurality of drain signal lines, each of said plurality of pixels being provided with a switching element operated by a scanning signal from one of said plurality of gate signal lines, and a pixel electrode supplied with a video signal from one of said plurality of drain signal lines via said switching element; said method comprising selecting pixels of a row of said pixels, and supplying a video signal to each of said selected pixels, said video signal being a binary signal corresponding to one bit of n bit data representing a gray scale, wherein: n pixel rows forming each of a plurality of groups are selected successively in a first columnwise direction within one of unit basic scanning periods, said each of said plurality of groups is formed of n pixel rows arranged in said each of said plurality of groups to be spaced from a preceding pixel row thereof by rows successively smaller in number by a factor of approximately 2, said unit basic scanning periods being a subdivision of one field period, said selection of n pixel rows is repeated in said first columnwise direction for each subsequent one of said plurality of groups of pixel rows wherein said pixel rows of said each subsequent one of said plurality of groups of pixel rows are shifted in a second columnwise direction, opposite from said first columnwise direction, and each of n pixel rows forming each of said plurality of groups is supplied with a binary signal corresponding to a different bit position of said n bit data, respectively, by turning on ones of said switching elements associated with said each of n pixel rows to select a corresponding one of said plurality of gate signal lines for one of plural approximately equal portions into which a corresponding one of said unit basic scanning periods is divided.
