Description

光源模块及具有该光源模块的背光模块和液晶显示器 技术领域
本发明属于液晶显示技术领域，具体地讲，涉及一种光源模块及具有该光源模块的背光模块和液晶显示器。
背景技术
随着信息社会的发展，人们对平板显示器的需求得到了快速的增长。液晶显示器(Liquid Crystal Display，简称LCD)具有体积小、功耗低、无辐射等特点，在当前的平板显示器市场占据了主导地位。然而，LCD自身不发光，需要借助其他发光器件提供的光源。因此，在LCD面板的后面配置提供光源的背光模块。
通常，诸如发光二极管(LED)的点光源被用作背光模块的光源。
近年来，随着液晶显示器的尺寸越来越大，当具有LED光源的背光模块应用到大尺寸的LCD时，现有技术是通过在多个基底上安装多个LED来形成背光模块中的光源模块。然而，现有技术形成的这种光源模块安装到背光模块中时，所需连接引线数量较多，造成组装繁琐，并且数量较多的连接引线会占据背光模块的较多空间，从而导致背光模块中的其他元件的利用空间不足。
发明内容
为了解决上述现有技术存在的问题，本发明的目的在于提供一种光源模块，包括：基底；多个发光元件，阵列安装在所述基底上；内部布线部分，形成在基底上并连接到所述多个发光元件；外围布线部分，形成在基底上并与所述内部布线部分绝缘；第一连接单元，形成在基底的第一侧上并连接到所述外围布线部分；第二连接单元，形成在基底的第二侧上并连接到所述内部布线部分和所述外围布线部分。
进一步地，所述多个发光元件包括一个或多个发光二极管。
进一步地，所述内部布线部分包括串联连接每行发光元件的第一内部引线、将串联的每行发光元件的正电极连接到所述第二连接单元的内正电极的第二内部引线以及将串联的每行发光元件的负电极连接到所述第二连接单元的内负电极的第三内部引线。
进一步地，所述外围布线部分包括连接所述第一连接单元的内正电极和所述第二连接单元的外正电极的第一外围引线以及连接所述第一连接单元的内负电极和所述第二连接单元的外负电极的第二外围引线。
本发明的另一目的还在于提供一种背光模块，包括多个上述的光源模块，其中，所述多个光源模块沿行方向或列方向排布，并且所述多个光源模块彼此电连接。
进一步地，每个光源模块的第二连接单元的内正电极与相邻的光源模块的第一连接单元的内正电极连接，每个光源模块的第二连接单元的内负电极与相邻的光源模块的第一连接单元的内负电极连接。
进一步地，处于沿行方向或列方向排布的多个光源模块的最末光源模块的第二连接单元的外正电极和内正电极均电连接供电电源的正电极，处于沿行方向或列方向排布的多个光源模块的最末光源模块的第二连接单元的外负电极和内负电极均电连接供电电源的负电极。
本发明的又一目的又在于提供一种液晶显示器，包括上述的背光模块以及与所述背光模块相对设置的液晶显示面板，所述背光模块向所述液晶显示面板提供显示光源，以使所述液晶显示面板显示图像。
进一步地，所述液晶显示面板包括薄膜晶体管阵列基板、与所述薄膜晶体管阵列基板相对设置的彩色滤光片基板以及夹设于所述薄膜晶体管阵列基板与所述彩色滤光片基板之间的液晶层。
本发明在将光源模块安装到背光模块中时，所需连接引线数量减少，简化组装过程，并且降低生产成本。另外，由于连接引线数量减少，所以连接引线占据背光模块的空间减少，从而提高背光模块中的空间利用率。

图2是根据本发明的实施例的背光模块的示意图。
参照图2，根据本发明的实施例的背光模块200包括多个图1所示的光源模块100，其中，这些光源模块100沿行方向或列方向排布，并且这些光源模块100彼此电连接。需要说明的是，根据本发明的实施例的背光模块200还包括背板、光学膜片等其他必要的光学部件，具体请参照现有技术的描述，在此不再赘述。
在图2中，示出了以列方向排布的2个图1所示的光源模块100，但本发明并不限制于此。可根据实际需求确定光源模块100的数量。此外，需要说明的是，根据实际需求，根据本发明的实施例的背光模块200可包括多个图2所示的由2个光源模块100形成的光源模块组合。例如，这些光源模块组合可沿行方向排布。
进一步地，处于上方的光源模块100的第二连接单元160的3个内正电极161A与处于下方的光源模块100的第一连接单元150的3个内正电极151A分别对应连接，处于上方的光源模块100的第二连接单元160的3个内负电极161B与处于下方的光源模块100的第一连接单元150的3个内负电极151B分别对应连接。
另外，处于沿列方向排布的这2个光源模块100的最末光源模块(即下方的光源模块100)的第二连接单元160的3个内正电极161A和3个外正电极162A均与所述外部供电电源的正电极连接，并且所述最末光源模块的第二连接单元160的3个内负电极161B和3个外负电极162B都与该外部供电电源的负电极连接。
图3是根据本发明的液晶显示器的结构示意图。
参照图3，根据本发明的液晶显示器包括液晶显示面板300及与液晶显示面板300相对设置的图2所示的背光模块200，其中，背光模块200提供显示光源给液晶显示面板300，以使液晶显示面板300显示影像。
液晶显示面板300通常包括薄膜晶体管(Thin Film Transistor，简称TFT)阵列基板310、与TFT阵列基板相对设置的彩色滤光片(Color Filter，简称CF)基板320以及夹设于TFT阵列基板310与CF基板320之间的液晶层330，其中，液晶层330中包括若干液晶分子。由于本发明的液晶显示面板300的具体 结构与现有技术的液晶显示面板的结构基本一致，所以在此不再详细描述。
综上，根据本发明的实施例，在将光源模块安装到背光模块中时，所需连接引线数量减少，简化组装过程，并且降低生产成本。另外，由于连接引线数量减少，所以连接引线占据背光模块的空间减少，从而提高背光模块中的空间利用率。
虽然已经参照特定实施例示出并描述了本发明，但是本领域的技术人员将理解：在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下，可在此进行形式和细节上的各种变化。
