Liquid crystal device and the driven method thereof

摘要

A liquid crystal device (LCD) and a driving method thereof are disclosed. The LCD includes a display panel, a data driven circuit configured for providing data voltages to the data lines, and a power reducing module. The display panel includes data lines, scanning lines intersecting with the data lines, and a matrix of pixels arranged in intersections of rows and columns. The power reducing module is 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, and changing a polarity inversion method of a timing controller. By changing the polarity inversion method of the timing controller basing on the input images, the display performance is guaranteed and the power consumption of the data driven circuit is reduced at the same time.

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.
