    • A drive system with small power loss in power conversion is provided. The drive system has an AC conversion device for converting commercial AC power from a commercial AC power supply and a DC conversion device. An AC power supply path for supplying power to discharge tubes, and a DC power supply path for supplying power to an image processing circuit or the like, are provided independently. The AC conversion device converts commercial AC power into converted AC power and gives the converted AC power to an AC drive device directly. Consequently, it is possible to reduce conversion steps for generating converted AC power and to reduce power loss that occurs in a conversion process. In particular, when power consumption of the discharge tubes is large, it is possible to reduce power loss in an entire liquid crystal display apparatus effectively by providing the AC conversion device.
    • 提供功率转换功率损耗小的驱动系统。 驱动系统具有用于从商用AC电源和DC转换装置转换商用AC电力的AC转换装置。 独立地提供用于向放电管供电的AC电源路径和用于向图像处理电路等供电的DC电源路径。 交流转换装置将商用交流电转换成转换后的交流电源,并将转换后的交流电力直接送到交流驱动装置。 因此,可以减少用于产生转换的AC电力的转换步骤并且减少在转换处理中发生的功率损耗。 特别地,当放电管的功耗大时,可以通过提供AC转换装置有效地降低整个液晶显示装置的功率损耗。
