  • Publication number: 20060152171
    Abstract: There is provided a liquid crystal display device using cold cathode fluorescent tubes as light sources for a liquid crystal display panel, wherein a plurality of the cold cathode fluorescent tubes, preferably two units of the cold cathode fluorescent tubes are adopted, so that lighting time of one unit of the cold cathode fluorescent tube is first reduced, and lighting time of another unit of the cold cathode fluorescent tube is subsequently reduced to thereby enable a luminance range from the maximum luminance to the minimum luminance to be widened. Further, there is provided a liquid crystal display device wherein luminance adjustment is implemented by keeping luminance characteristics of cold cathode fluorescent tubes in the best state by measuring temperature of the cold cathode fluorescent tubes or controlling the temperature of the cold cathode fluorescent tubes at a constant temperature to thereby enable luminance adjustment in a wide range to be implemented without causing one-sided lighting.
