摘要： PURPOSE: A balance transformer is provided to reduce the thickness and size of the balance transformer by applying a U-U core. CONSTITUTION: An input-output terminal is inserted into the lower part of a bobbin(120). A core is inserted into a core inserting hole. The core is composed of a U-U core(110) with a simple structure. The structure of the U-U core is a slim shape. A bobbin guide(130) minimizing the twisting of the U-U core is formed in the boundary line between a section(140) and the core inserting hole. A section for the guarantee of insulation distance(141) formed by a partition wall is formed in the end of the high voltage side of the section.
摘要翻译：目的：提供平衡变压器，通过应用U-U磁芯来减小平衡变压器的厚度和尺寸。构成：输入输出端子插入线轴（120）的下部。将芯插入到芯插入孔中。该芯由具有简单结构的U-U型芯（110）组成。 U-U型芯的结构是细长的。在区段（140）和芯插入孔之间的边界线中形成使U-U芯的扭转最小化的绕线管引导件（130）。在该部分的高压侧的端部形成有由隔壁形成的用于保证绝缘距离（141）的部分。

摘要： PURPOSE: A backlight unit, an operation method thereof, and a liquid crystal display device with the same are provided to supply reference level which changes in proportion to lowered input voltage, thereby providing a power supply device which efficiently operates in abnormal circumstance. CONSTITUTION: An inverter(1124) supplies input voltage to an optical source. A pattern capacitor is defined by patterns which are formed on the upper side and the lower side of a printed circuit board. A protection circuit(1146) is mounted on the printed circuit board. The protection circuit detects open optical source protection level which changes according to the change of the input voltage.
摘要翻译：目的：提供背光单元及其操作方法以及具有该背光单元的液晶显示装置，以提供与降低的输入电压成比例地变化的参考电平，从而提供在异常情况下有效操作的电源装置。构成：逆变器（1124）向光源提供输入电压。图案电容器由形成在印刷电路板的上侧和下侧的图案限定。保护电路（1146）安装在印刷电路板上。保护电路检测根据输入电压变化而变化的开路光源保护电平。
