摘要： A method of driving a gray scale and a drive circuit therefor are provided in which the simplification and reduction of the operating speed of a circuit for generating display voltages in a matrix display device are promoted, and low cost and multi-color display of high minuteness are simultaneously realized. The display circuit for generating the display voltages is composed of an image signal processing circuit for dividing an input digital image signal into plural bit groups, a first display voltage generating circuit for generating the display voltages corresponding to the first bit group obtained by the division, a second display voltage generating circuit for generating the display voltages corresponding to the second bit group obtained by the division, and a line-at-a-time timing circuit. The first and second display voltage generating circuits are operated in parallel to combine the outputs thereof with one another, thereby to generate a gray scale displaying voltage.
