Abstract:
A liquid crystal display system comprising:a liquid crystal panel including pixels which are arranged in a plurality of lines and a plurality of columns in a matrix form;gray-scale voltage generating means which receives display data for a plurality of lines to convert the display data to a gray-scale voltage and supplies the gray-scale voltage to the pixels; andscan means for setting the pixels to one of a selection status and a non-selection status;wherein each of the pixels includes a switching element, a pixel electrode, a liquid crystal element, and a liquid crystal common electrode;wherein an induced ratio of light is controlled based onthe gray-scale voltage which is transmitted from the gray-scale voltage generating means and applied to the pixel electrode through the switching element, andan effectiveness voltage of the liquid crystal common voltage which is a voltage of the liquid crystal common electrode, thereby performing a gray-scale display;wherein the scan means includes a plurality of scan circuits; andwherein the liquid crystal display system further comprises:means for simultaneously setting all output signals of each of at least one of the scan circuits to a selection status;means for sequentially setting output signals of each of all remaining ones of the scan circuits to the selection status; andmeans for changing a number of lines to be selected by at least one of the scan circuits based on a comparison between a total number of the lines of the display data and a total number of the lines of the liquid crystal panel.
