Abstract:
1. A liquid crystal display (LCD), comprising: a display panel comprising a plurality of data lines, a plurality of scanning lines intersecting with the data lines, and a matrix of pixels arranged in intersections of rows and columns; a data driven circuit configured for providing data voltages to the data lines; and a power reducing module configured for storing a most-reload-image, comparing the data of the most-reload-image and the data of an input image, determining if the input image is a reload image increasing a power consumption of the data driven circuit according to a comparison result, and changing a polarity inversion method of a timing controller according to a determination result; and wherein the data of the input image comprises gray scale values of each of the pixels in the input image, the data of the most-reload-image comprises the gray scale values of each of the pixels in the most-reload-image, wherein the gray scale values of each of the pixels in the input image are compared with the gray scale values of each of the pixels in the most-reload-image to obtain a gray level ratio for each of the pixels.
