    • A backlight of an LCD(Liquid Crystal Display) using a light emitting diode is provided to form the lines for electrically connecting LEDs(Light Emitting Diodes) with a driving circuit connecting connector on the surface opposite to the arrangement surface of LEDs. A double-sided PCB(Printed Circuit Board) has plural division areas and conduction via holes. Plural light emitting diodes are arranged at the upper surface of the double-sided PCB. Plural driving circuit connection connectors(25) are arranged at a side of the double-sided PCB. Plural first lead patterns(26) are formed on the upper surface of the double-sided PCB and electrically connect plural light emitting diodes located at the division areas. Plural second lead patterns are formed on the lower surface of the double-sided PCB and electrically connect the first lead patterns and the connectors through the conduction via holes. The double-sided PCB also includes heat radiating via holes penetrated from the upper surface to the lower surface having LEDs arranged thereon. The first lead patterns adjacent to the connectors are directly connected with the connectors.
    • 提供使用发光二极管的LCD(液晶显示器)的背光,以形成用于将LED(发光二极管)与驱动电路连接连接器电连接在与LED的布置表面相对的表面上的线。 双面PCB(印刷电路板)具有多个分割区域和导通通孔。 多个发光二极管布置在双面PCB的上表面。 多个驱动电路连接连接器(25)布置在双面PCB的一侧。 多个第一引线图案(26)形成在双面PCB的上表面上并电连接位于分割区域的多个发光二极管。 多个第二引线图案形成在双面PCB的下表面上,并通过导电通孔电连接第一引线图案和连接器。 双面PCB还包括从上表面到下表面穿透的散热通孔,其上布置有LED。 与连接器相邻的第一引线图案与连接器直接连接。
