    摘要： A backlight driving circuit is controlled by a timing controller and executes on/off control of the backlights. The timing controller detects, using a synchronous signal, a change in a blank period which is of one frame period for display of one screen, during which the image signal is not transmitted. Upon detecting the change in the blank period, the timing controller adjusts the on-periods of the backlights in order to make the brightness of the backlights equal to one another. Consequently, the backlights have an equal brightness with one another in spite of the change in the blank period. This makes the lives of the backlights equal to one another. In a case where the plural backlights constitute a backlight unit, a reduction in life of the backlight unit is prevented. Further, it is also possible to prevent the brightness of the backlights from being differentiated even through a long-term use.

    摘要： An illumination device is provided which can reduce a movement blur and a tailing phenomenon on a motion picture display while a drop in display brightness is suppressed, and which can suppress power consumption, can be made small and light, and can prolong the lifetime, and a liquid crystal display device using the same is provided. A light source control part of a control circuit synchronizes a latch pulse signal outputted from a gate driver control part to a gate driver, and outputs light emission control signals to respective light source power supply circuits. The respective light source power supply circuits change emission states of cold cathode fluorescent lamps to one of a first to a third emission states on the basis of the inputted light emission control signals, and illuminate an LCD panel from a rear surface of a display area. A first stage emission state is a non-lighting state, a second stage emission state is a maximum lighting state in which maximum lighting brightness is obtained, and a third emission state is an intermediate lighting state in which brightness of about one half of the second stage emission state is obtained.
