摘要： A drive circuit device for a display device which drives a plurality of source bus lines provided on a display panel includes a driver unit that receives a clock signal, a data signal and a control signal, sequentially fetches the data signal, and generates drive signals for the source bus lines in accordance to the fetched data signal. The device further includes a gate unit that, after elapse of specified time from the reception of the driver unit, and at a timing when a rear-stage drive circuit device starts receiving, starts outputting of a propagation signal including at least one of the clock signal, data signal and control signal to the rear-stage drive circuit device. Consequently, the power consumption required for supplying these signals and the generated amount of electromagnetic waves resulting from the signal supply can be suppressed.

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.

摘要： The liquid crystal display device has a liquid crystal panel in which liquid crystal cells are disposed in intersection areas of scanning lines and data lines, respectively. A picture signal and a synchronous signal are supplied via external terminals, respectively. A timing controller generates a driving timing of the scanning lines and a driving timing of the data lines in response to the synchronous signal. Further, the timing controller varies at least one of the driving timing of the scanning lines and the driving timing of the data lines according to a cycle of the synchronous signal in order to keep a writing time of the picture signal supplied to the liquid crystal cells constant. Therefore, it is possible to keep the writing time constant even when the cycle of the synchronous signal varies, which can prevent the deterioration in display quality.
