【具体实施方式】
请参见图2-3，图2是根据本发明第一实施例的平板显示装置的结构示意图，图3是根据本发明第二实施例的平板显示装置的背框的第一实施例的结构示意图。如图2所示，本实施例的平板显示装置20包括：背光系统21以及显示面板22，背光系统21设置于显示面板22的背面，并且为显示面板22提供光源。
在本实施例中，背光系统21包括光源25、匀光机构24以及背框23。其中，背框23承载光源25和匀光机构24。在背光系统21为侧光式时，匀光机构24是导光板；在背光系统21为直下式时，匀光机构24是扩散板。背框23包括至少第一主拼接件和第二主拼接件，至少第一、第二两个主拼接件形成背框23的主框架27。
一起参阅图3，背框23的第一实施例包括第一主拼接件261以及第二主拼接件262。第一主拼接件261的一端与第二主拼接件262的一端拼接，第一主拼接件261的另一端与第二主拼接件262的另一端拼接，以形成背框23的主框架27。第一主拼接件261和第二主拼接件262均为铝件或镀锌钢件。在本实施例中，第一主拼接件261和第二主拼接件262为L形。
参阅图4-图10，图4-图10是对图3所示拼接处区域1俯视图的局部放大示意图。第一主拼接件261和第二主拼接件262采用多个分散的拼接点进行拼接，图4-图10中圆环表示拼接点，此处未对其进行标示。第一主拼接件261和第二主拼接件262在拼接点通过铆接、焊接或螺接等方式拼接成一体。优选地，拼接点对应均匀分布在第一主拼接件261和第二主拼接件262相拼接区域的表面。
本发明中，拼接点的个数为四个（如图4所示）、三个（如图5所示）或其它数目，视具体情况进行设定。在拼接点的个数为四个的情况下，四个拼接点呈矩形排列（如图4所示）。在拼接点的个数为三个的情况下，三个拼接点呈三角形排列（如图5所示），当然，在图5中各拼接点所处区域可以为圆角，以更多分散应力。
除设置多个分散的拼接点之外，第一主拼接件261和第二主拼接件262的拼接点所在区域为面积膨大形状（如图6-图8所示）。一般而言，膨大形状为圆形膨大，并且进行拼接的第一主拼接件261和第二主拼接件262的所有拼接点所处区域均为面积膨大形状。当然，膨大形状不仅限于圆形膨大，也可以是三角形或者方形等其它形状，只要能分散背框23的第一主拼接件261和第二主拼接件262相拼接区域应力即可，此处不对膨大形状做过多限制。全文中，应力指单位面积上所承受的附加内力，应力过大时可能会影响材料的形状和尺寸。所以需要将第一主拼接件261和第二主拼接件262的拼接点所处区域的应力进行分散，以减小单位面积上所承受的附加内力。
具体的，第一主拼接件261和第二主拼接件262的拼接点所在区域为面积膨大形状时，如图6所示，拼接点可设置于没有分叉的第一主拼接件261上。当然，拼接点也可设于同一主拼接件不同分叉上。参阅图7和图9，第二主拼接件262的一端为分叉结构，分叉均与第一主拼接件261进行拼接，分叉可为两个，也可以为更多个。
如图7所示，每一个分叉上设置有四个拼接点，每个拼接点所占分叉面积比例较小，此时，需要设置面积膨大形状。而如图9所示，每一个分叉上可仅设置两个拼接点，相对而言，因为每个拼接点所占分叉面积比例较大，此时可以不需要设置面积膨胀形状。
除此之外，可在第一主拼接件261邻近拼接点的侧边设置水平延伸的凸块（如图8所示）。增设凸块可增大第一主拼接件261侧边区域的面积，相对将拼接点设置得更分散，能分散更多的应力。
参阅图10，第一主拼接件261和第二主拼接件262在拼接点处也可以为加厚结构。在拼接点处，第一主拼接件261和第二主拼接件262可均设有加厚结构，亦可在第一主拼接件261设有加厚结构，或者可在第二主拼接件262设有加厚结构。
本发明实施例，通过拼接方式形成背框，使背框的结构简单，并且节省背框的材料，可降低背光显示装置的生产成本。并且，在第一主拼接件261和第二主拼接件262相拼接区域采用多个分散的拼接点进行拼接，能够在保证背框拼接处的强度的同时分散应力，进一步保证背框整体的强度达到要求。
值得注意的是，前述采用多个拼接点的各个实施例也适用于下述各背框、背光系统或平板显示装置的实施例。
一起参阅图11，背框23的第三实施例包括第一主拼接件281、第二主拼接件282以及第三主拼接件283。三个主拼接件281、282以及283拼接形成背框23的主框架27。三个主拼接件281、282以及283均为铝件或镀锌钢件。在本实施例中，第一主拼接件281为L形，第二、三拼接件282、283均为直条形。
此外，背框23还可以包括设置于主框架27内并与之拼接的辅拼接件。
以下以四个主拼接件和两个辅拼接件详细说明本发明平板显示装置20的背框23。
请参见图12，图12根据本发明第四实施例的平板显示装置的背框的结构示意图。如图12所示，在本实施例中背框23包括：第一主拼接件231、第二主拼接件232、第三主拼接件233、第四主拼接件234、第一辅拼接件235、第二辅拼接件236以及支架2371、2372、2373、2374、2375、2376及2377。第一主拼接件231、第二主拼接件232、第三主拼接件233以及第四主拼接件234通过首尾拼接形成背框23的主框架27。第一辅拼接件235和第二辅拼接件236作为辅拼接件，设置于主框架27内，并且与主框架27拼接。
具体而言，第一主拼接件231的一端与第二主拼接件232的一端拼接，第二主拼接件232的另一端与第三主拼接件233的一端拼接，第三主拼接件233的另一端与第四主拼接件234的一端拼接，第四主拼接件234的另一端与第一主拼接件231的另一端拼接，以形成长方形的主框架27。其中，第一主拼接件231、第二主拼接件232、第三主拼接件233以及第四主拼接件234均为铝件或镀锌钢件。在本实施例中，第一主拼接件231、第二主拼接件232、第三主拼接件233以及第四主拼接件234均为直条形，在其他实施例中，本领域技术人员完全可以将第一主拼接件231、第二主拼接件232、第三主拼接件233以及第四主拼接件234全部设置为L形，或部分设置为直条形，剩余的设置为L形。例如，在图3中，第一主拼接件261和第二主拼接件262全部设置为L形；在图11中，第一主拼接件281设置为L形，第二、三主拼接件282以及283设置为直条形。
参见图13，图13是根据本发明第五实施例的平板显示装置的拼接方式的结构示意图。在本实施例中，平板显示装置20的背框23均采用拼接连接方式进行拼接固定。如图13所示，以第一主拼接件231的一端与第二主拼接件232的一端拼接连接方式为例，将第二主拼接件232的一端拼接在第一主拼接件231的一端上，比如，采用螺接、扣接或焊接等方式将第二主拼接件232的一端拼接在第一主拼接件231的一端上。
参见图14，图14是根据本发明第六实施例的平板显示装置中的第一辅拼接件对角设置在主框架上的示意图。在本实施例中，第一辅拼接件235和第二辅拼接件236设置于背框23的主框架27内。第一辅拼接件235的一端与第一主拼接件231拼接，第一辅拼接件235的另一端与第三主拼接件233拼接，第二辅拼接件236的一端与第一主拼接件231拼接，第二辅拼接件236的另一端与第三主拼接件233拼接，并且第二主拼接件232、第四主拼接件234、第一辅拼接件235以及第二辅拼接件236之间平行设置。在其它实施例中，本领域技术人员在主框架27内设置至少一个辅拼接件，例如在主框架27内仅仅设置第一辅拼接件235。此外，第一辅拼接件235的两端可以分别与第一主拼接件231、第二主拼接件232、第三主拼接件233以及第四主拼接件234中的至少两个主拼接件拼接，例如第一辅拼接件235对角设置在主框架27内，如图14所示。同理可知，第二辅拼接件236的两端亦可以分别与第一主拼接件231、第二主拼接件232、第三主拼接件233以及第四主拼接件234中的至少两个主拼接件拼接。
参见图15，图15是根据本发明第七实施例的平板显示装置中的第一辅拼接件以及第二辅拼接件在主框架上的示意图。例如，第一辅拼接件235的两端分别与相邻设置的第一主拼接件231、第二主拼接件232拼接，第二辅拼接件236的两端分别与相邻设置的第三主拼接件233、第四主拼接件234拼接。
并结合图11-图15，在上述实施例中，背框23包括七个支架2371、2372、2373、2374、2375、2376及2377。其中，支架2371固定于第四主拼接件234上，支架2372、2373分别固定于第一辅拼接件235上，支架2374固定在第二辅拼接件236上，支架2375固定在第二主拼接件232上，支架2376、2377的两端分别固定于第一辅拼接件235和第二辅拼接件236上。实际上，支架可以固定于第一主拼接件231、第二主拼接件232、第三主拼接件233、第四主拼接件234、第一辅拼接件235以及第二辅拼接件236之一或以上。在其他实施例中，本领域技术人员完全可以在背框23上设置其他数量的支架，比如一个支架或以上。此外，支架可以拆卸固定于第一主拼接件231、第二主拼接件232、第三主拼接件233、第四主拼接件234、第一辅拼接件235以及第二辅拼接件236之一或以上。
在支架2371、2372、2373、2374、2375、2376及2377上均设有凸包（未标示），背框23可以通过凸包固定电路板等器件。
以下进一步说明上述背框23相应的模具。在本实施例中，第一主拼接件231和第三主拼接件233的尺寸相同，形状相同，使用相同的模具冲压制得。第二主拼接件232、第四主拼接件234、第一辅拼接件235以及第二辅拼接件236的尺寸相同，形状相同，使用相同的模具冲压制得，实现模具共用。因此，本发明的背框23可以通过使用两种小尺寸模具冲压制得，相比于现有技术中背框10需要大尺寸模具，本发明的背框23的模具结构简单且小，进而降低背框23模具的成本。此外，本发明的背框23相对于现有技术中背框10的整体背框，能够大幅节省材料，以降低平板显示装置20的生产成本。
请参见图16，图16是根据本发明第八实施例的一种平板显示装置的背框中拼接部的结构示意图。如图16所示，在本实施例中，第一主拼接件的一端设有两个拼接部，拼接部的结构与相应的第二主拼接部的一端适配，以使第一主拼接件与相应的第二主拼接件的一端拼接。
具体而言，第一主拼接件231的一端设有拼接部2311、2312，拼接部2311、2312沿第一主拼接件231的长度方向上间隔排列，拼接部2311、2312是在第一主拼接件231设置的形状与第二主拼接件232的一端适配的凹部，以收容第二主拼接件232的一端。
如图17所示，图17是图16中拼接部的第一实施例的截面示意图。拼接部2311、2312为未贯穿第一主拼接件231的一端相对两侧面的凹部，凹部的形状为矩形，第二主拼接件232为一直条形。
在拼装较大尺寸背框23时，首先选择较邻近第一主拼接件231的端部的拼接部2311，并选择相应宽度的第二主拼接件232。随后将第二主拼接件232的一端设置在拼接部2311的凹部上。随后通过螺接、扣接或焊接等方式将第二主拼接件232的一端拼接固定在拼接部2311上。在拼装较小尺寸背框23时，首先选择较远离第一主拼接件231的端部的拼接部2312，并选择相应宽度的第二主拼接件232。随后将第二主拼接件232的一端设置在拼接部2312的凹部上。随后通过螺接、扣接或焊接等方式将第二主拼接件232的一端拼接固定在拼接部2312上。
请参见图18，图18是根据本发明第九实施例的一种平板显示装置的背框中拼接部的拼接方式的示意图。例如在第二主拼接件232的表面相应位置设有凸起，其中第二主拼接件232的凸起嵌入第一主拼接件231相对应位置的凹部，以拼接第一主拼接件231和第二主拼接件232，如图18所示。此外，所述第二主拼接件232的一端表面可以设有至少两个沿第二主拼接件232长度方向上间隔排列的凸起，比如两个、三个或四个等。
更进一步，如图19所示，图19是根据本发明第十实施例的一种平板显示装置的背框中拼接部的拼接方式的示意。第一主拼接件231的凹部为多阶梯结构的凹部，第二主拼接件232相对应位置设有与凹部适配的多阶梯结构的凸部，如图19所示。
此外，如图20所示，图20是根据本发明第十一实施例的一种平板显示装置的背框中拼接部的拼接方式的示意图。以拼接部2311为例，第一主拼接件231的凹部底部设有第一贯穿孔2313，第二主拼接件232相应于拼接部2311的位置上设有第二贯穿孔2321，背框23进一步包括固定件240，固定件240穿过第一贯穿孔2313和第二贯穿孔2321，以将第一主拼接件231和第二主拼接件232拼接。
如图21，图21是根据本发明第十二实施例的一种平板显示装置的背框中拼接部的结构示意图。在本发明平板显示装置的背框的另一实施例中，第一主拼接件231的拼接部2311、2312的凹部形状为圆形。但是，在其他实施例中，本领域技术人员完全可以将凹部的形状设置成三角形等其他多边形形状。
如图22，图22是根据本发明第十三实施例的一种平板显示装置的背框中拼接部的结构示意图。在本发明平板显示装置的背框的另一实施例中，拼接部2311、2312为贯穿第一主拼接件231的相对两侧的凹部，以使第二主拼接件232的一端在拼接部2311、2312上移动。比如在第二主拼接件232的一端穿出拼接部2312并拼接固定后，可裁切掉穿出部分，进而调节第二主拼接件232在作为背框主拼接件时的长度。
在实际应用中，第一主拼接件231的另一端以及第三主拼接件233的两端均设有两个拼接部，其结构与拼接部2311、2312的结构相同；而在第二主拼接件232的两端和第四主拼接件234的两端，对应于不同的情况，也相应进行设计或不设计，比如：
1）第一种情况，如图17所示，第二主拼接件232的两端和第四主拼接件234的两端可以不进行任何设计，即端部与其他部位的结构相同，这时候在选择第一主拼接件231一端的不同拼接部2311（2312）进行拼接时（另一端同样处理），若想背框23的宽度相应变化，则相应的第二主拼接件232和第四主拼接件234的长度也作相应的选择。即，若选邻近第一主拼接件231一端的拼接部2311进行拼接，则不对第二主拼接件232和第四主拼接件234进行裁剪，或裁剪掉的部分较短；若选择较远离第一主拼接件231一端的拼接部2312进行拼接时，则对第二主拼接件232和第四主拼接件234均进行裁剪，按照拼接部距离第一主拼接件231一端的远近，裁剪掉的部分也较长或较短；
2）第二种情况，类似前述第一种情况，如图18所示，只不过第二主拼接件232和第四主拼接件234以不同的凸起来分别与第一主拼接件231和第三主拼接件233配合，实现背框23的宽度变化；同样，若选择除离第一主拼接件231一端最近的第一拼接部2311之外的其他拼接部2312进行拼接时，在拼接后或拼接前，将多出的第二主拼接件232和第四主拼接件234部分进行裁剪。
以上情况也适用于仅用两个L形主拼接件进行拼接而得到背框23的主框架27。综上所述，本发明的背框23的第一主拼接件上设有至少两个拼接部，根据用户需求进行设置拼接部的数量，在本实施例中选取两个拼接部2311、2312进行描述。因此，在设置背框23的模具时，仅需设置两组模具，即第一主拼接件的模具以及第二主拼接件的模具，在第一主拼接件上设置多个拼接部以拼接得到各种尺寸的背框23。在拼装背框23时，可以根据背框23的尺寸，选择相应的拼接部，通过拼接部将第二主拼接件拼接在第一主拼接件的拼接部上，并将第一主拼接件中位于第二主拼接件的拼接位置外侧的其他拼接部裁切掉，以获取所需尺寸的背框23。相对于现有技术中根据不同尺寸的背框10设置不同背框模具，本发明的平板显示装置的背框23仅需设置第一主拼接件的模具和第二主拼接件28的模具，实现满足各种尺寸产品要求的模具共用，并且模具结构简单，能够降低背框模具的成本。
本发明还提供一种制造平板显示装置的背框的模具，该背框的模具设有用于形成背框的主拼接件的主图案，主图案设有上设有用于在主拼接件的一端形成至少两个拼接部的子图案。其中，主拼接件为上述第一主拼接件和第二主拼接件，对应上述的主图案；拼接部为上述第一主拼接件的拼接部，对应上述的子图案，在此不再赘述。

步骤501：制作至少第一、第二两个主拼接件，其中第一主拼接件的一端设有至少两个拼接部，每个拼接部的结构与相应的第二主拼接件一端适配。
步骤502：根据背框的尺寸选择至少两个拼接部的一拼接部与相应的第二主拼接件的一端拼接，将至少两个主拼接件进行拼接，并且至少两个主拼接件采用多个分散的拼接点进行拼接。
在本实施例中，当第二主拼接件的拼接位置与第一主拼接件的相邻端部之间存在其他拼接部时，在根据背框的尺寸选择至少两个拼接部的一拼接部与相应的第二主拼接件的一端拼接的步骤之前或之后，将第一主拼接件中位于第二主拼接件的拼接位置外侧的其他拼接部裁切掉。其中第一主拼接件为上述第一主拼接件，第二主拼接件为上述第二主拼接件，在此不再赘述。
如图24所示，图24是根据本发明第十五实施例的一种具有触摸屏的平板显示装置的结构示意图。本发明的平板显示装置20进一步包括一触摸屏29，触摸屏29设置在平板显示装置20的显示面板22的出光面上。其中，平板显示装置20包括：背光系统21以及上述的显示面板22，背光系统21设置于显示面板22的背面，并且为显示面板22提供光源。
背光系统21包括光源25、匀光机构24以及背框23。其中，背框23承载光源25和匀光机构24。在背光系统21为侧光式时，匀光机构24是导光板；在背光系统21为直下式时，匀光机构24是扩散板。背框23包括至少第一主拼接件和第二主拼接件，至少第一、第二两个主拼接件形成背框23的主框架27。
值得注意的是，本发明的平板显示装置20可以为液晶显示装置或液晶电视机。
本发明还提供一种立体显示装置30，如图25所示，图25是根据本发明第十六实施例的立体显示装置的结构示意图。立体显示装置30包括液晶透镜光栅31、背光系统32以及显示面板33。其中，液晶透镜光栅31设置于显示面板33的出光面上。背光系统32为上述各实施例的背光系统，比如背光系统32包括背框23。其中，背框23包括至少第一主拼接件和第二主拼接件，至少第一、第二两个主拼接件形成背框的主框架，在此不再赘述。

通过上述方式，本发明平板显示装置、立体显示装置以及等离子显示装置的背框模具结构简单，降低背框模具的成本，并且节省背框的材料，以降低平板显示装置的成本。
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。
