Liquid crystal display device employing dot inversion drive method with reduced power consumption

摘要

A liquid crystal display device employing a dot inversion drive method includes a pixel array, a data driver circuit, a short circuit, and a scanning circuit. The short circuit is disposed for respective outputs of the data driver circuit, and includes a switching element for connecting each of the outputs to a precharge voltage different from an output voltage. The short circuit includes the switching element disposed in one of a first switching group and a second switching group; the switching element of one of the first switching group and the second switching group is connected to respective pairs of pixel column units including an odd-numbered pixel column and an even-numbered pixel column which are adjacent to each other; and the pairs of pixel column units which are adjacent to each other are each connected to the switching element disposed in respective switching groups different from each other.
