    • 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.
    • 液晶显示装置具有分别在扫描线和数据线的交叉区域配置液晶单元的液晶面板。 分别通过外部端子提供图像信号和同步信号。 定时控制器响应于同步信号产生扫描线的驱动定时和数据线的驱动定时。 此外,定时控制器根据同步信号的周期来改变扫描线的驱动定时和数据线的驱动定时中的至少一个,以保持提供给液晶单元的图像信号的写入时间 不变。 因此,即使当同步信号的周期变化时也可以保持写入时间恒定,这可以防止显示质量的劣化。

    • 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.
    • 背光驱动电路由定时控制器控制,并执行背光的开/关控制。 定时控制器使用同步信号检测在一个屏幕的显示期间的一个帧周期的变化,在该周期期间图像信号不被发送。 当检测到空白期间的变化时,定时控制器调节背光的接通周期,以使背光的亮度彼此相等。 因此,尽管空白期间的变化,背光灯彼此具有相等的亮度。 这使得背光灯的生命相互等同。 在多个背光构成背光单元的情况下,防止背光单元的寿命缩短。 此外,即使长期使用也可以防止背光的亮度差异化。

    • 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.
