【具体实施方式】
下面结合附图和实施例对本发明进行详细说明。
图1是本发明的背光源的结构示意图。如图1所示，背光源10由至少两个背光源拼接单元100以可拆卸方式电性连接而成。本发明实施例的背光源10包括至少两个背光源拼接单元100以及导电件200。

其中，支架110包括两端111、112以及位于两端之间的中间部113，两端111、112设置有引脚设置区域，中间部113为发光件120的设置区域。支架110的两端111、112上皆分别设置了至少一个引脚130。发光件120设置在支架110的中间部113上，且本实施例中的发光件120优选为LED发光件。
支架110的尺寸只需能够容纳发光件120以及引脚130即可，且无需特别加工。本实施例中，支架110呈长方体，两相邻的背光源拼接单元100沿支架110的长度方向上电性连接。
请再参考图1，背光源10通过导电件200电性连接相邻的两个背光源拼接单元100，并且两个背光源拼接单元100可直接通过导电件200实现结构上的可拆卸连接。具体的，导电件200的一端201电性连接两相邻的背光源拼接单元100的其中一个支架110的一端111上的引脚，导电件200的另一端202电性连接另一个支架110的另一端112上的引脚，以实现两相邻的背光源拼接单元100的电性连接。
本实施例中，导电件200采用各向异性导电材料制成，由于该导电材料可以做的很薄，因此也不会对背光模组的光学品质产生任何不良的影响。当然，在其他实施例中，还可以采用连接胶布以及设置在连接胶布上的导电材料一起作为导电件200，连接胶布连接两相邻的支架110的两端111、112，其上设置的导电材料与引脚130配合则可实现两个背光源拼接单元100电性连接。
图3是本发明第二实施例的背光源拼接单元的主视图，图4是图3中背光源拼接单元的左侧视图。如图3-4所示，本实施例中，背光源拼接单元300包括支架310、发光件320以及至少两个引脚330。支架310包括两端311、312、位于两端之间的中间部313、第一拼接部314以及第二拼接部315。其中，两端311、312、位于两端之间的中间部313、发光件320以及至少两个引脚330的结构与背光源拼接单元100的两端111、112、位于两端之间的中间部113、发光件120以及至少两个引脚130的结构相同，此处不再赘述。

本实施例中，第一拼接部314为两个凹槽，第二拼接部315为与该凹槽适配的两个凸起部，凸起部嵌入凹槽中以拼接两相邻的背光源拼接单元300。
图5是本发明的平板显示装置的结构示意图。如图5所示，本发明还提供了一种背光系统20和平板显示装置50。其中，平板显示装置50包括背光系统20、显示面板30以及触摸屏40。其中，背光系统20设置于显示面板30的背面，并且为显示面板30提供光源。
背光系统20包括背光源21、匀光机构22以及背框23。其中，背框23承载背光源21和匀光机构22。在背光系统20为侧光式时，匀光机构22是导光板；在背光系统20为直下式时，匀光机构22是扩散板。背光源21可以采用本发明前述任一种实施例所示的背光源的结构。
本发明的平板显示装置50可以为液晶显示装置或液晶电视机。
通过上述方式，本发明的背光源、背光系统以及平板显示装置能根据设计需求任意拼接，其结构简单，安装方便且成本低廉。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
