摘要： It is possible to realize a driver circuit which exhibits low power consumption and high image quality in a liquid crystal display device used in miniaturized portable equipment. In a liquid crystal display device which includes a liquid crystal display element and a liquid crystal driver circuit, the liquid crystal driver circuit is mounted on one side of a liquid crystal display panel. The liquid crystal driver circuit can output counter electrode voltages of two systems and hence, the liquid crystal driver circuit can select a first mode in which the first counter voltage and the second counter voltage have the opposite polarities from each other and a second mode in which the first counter voltage and the second counter voltage have the same polarity. Due to such constitution, while driving the liquid crystal display device in the first mode, the second mode is selected depending on a video signal thus realizing power saving.

摘要： A driver circuit including a DA converting circuit that converts video data input from the outside to a grayscale voltage; an amplifying circuit that amplifies the grayscale voltage; and a switch circuit that selects the grayscale voltage output from the amplifying circuit and a predetermined voltage as a voltage that is output to the image line. When video data indicating a minimum grayscale, the switch circuit outputs the predetermined voltage to the image line, and when video data indicating a grayscale other than the minimum grayscale is input, the switch circuit outputs the grayscale voltage output from the amplifying circuit to the image line. The predetermined voltage allows a voltage of the pixel electrode and a voltage of the counter electrode after passage of the writing of the image voltage to be coincident with each other.
