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5，图5根据本发明第四实施方式的平板显示装置的背框的结构示意图。如图5所示，在本实施方式中背框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的矩形主框架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。在本实施方式中，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，在其他实施方式中，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4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。
在本实施方式中，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6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。
在本实施方式中，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。在其它实施方式中，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7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。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，如图8所示。
在本实施方式中，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。在其他实施方式中，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可以通过该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。在本实施方式中，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9，图9是根据本发明第八实施方式的一种平板显示装置的背框中拼接部的结构示意图。如图9所示，在本实施方式中，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10所示，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。具体上，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11所示。此外，所述第二主拼接件232的一端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，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12所示。此外，如图13所示，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14，在本发明平板显示装置的背框的另一实施方式中，第一主拼接件231的拼接部2311、2312的凹部形状为圆形。但是，在其他实施方式中，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15，在本发明平板显示装置的背框的另一实施方式中，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10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11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，在本实施方式中选取两个拼接部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。
请参阅图16-21，下面以四个主拼接件和两个辅拼接件为例，说明说明本发明平板显示装置20的背框23在主拼接件设置有光源时，该主拼接件和其它未设置光源的主拼接件在材料选择上的不同以及该主拼接件的卡勾的制作过程。
第一主拼接件291、第二主拼接件292、第三主拼接件293、第四主拼接件294、第一辅拼接件295以及第二辅拼接件296组成背框290。光源300可设置于第一主拼接件291、第二主拼接件292、第三主拼接件293和第四主拼接件294中至少一个主拼接件上。用于光源300的主拼接件具有第一散热性能，其余不用设置光源300的主拼接件具有第二散热性能，并且第一散热性能优于第二散热性能。其中，用于设置光源300的主拼接件的材料可选为铝挤。当用于设置光源300的主拼接件的材料可选为铝挤时，用于设置光源300的主拼接件的铝挤的向下卡勾由倒L形铝挤铣出。
以下以光源300设置于第三主拼接件293上进行详细说明。光源300设置于第三主拼接件293的向上折弯的侧壁2931上的一表面，第三主拼接件293的侧壁2931远离光源的另一表面设置有卡勾2932。第三主拼接件293具有第一散热能力，其余的远离光源300的第一主拼接件291、第二主拼接件292和第四主拼接件294具有第二散热能力，并且第一散热能力优于第二散热能力。在本发明实施方式中，设置于光源300的第三主拼接件293的材料选用为散热性能较好的铝挤，以利于散热，其余的第一主拼接件291、第二主拼接件292和第四主拼接件294的材料选用为散热性一般的镀锌钢件。当设置于光源300的第三主拼接件293的材料选用为铝挤材料时，无法使铝挤材料通过冲压而形成第三主拼接件293的卡勾2932，可使铝挤材料通过铝挤挤出制程形成设置光源300的第三主拼接件293材料。其中，第三主拼接件293材料包括向上折弯的侧壁2931和自侧壁2931向远离光源300的另一表面延伸起而形成的倒L型待加工块2933，铣掉倒L型待加工块2933下端靠内侧部分，从而形成卡勾2932。卡勾2932的数量为两个，分别为第一卡勾29321和第二卡勾29322。第一卡勾29321用于与前框280的卡合结构2801配合，使得前框280固定于背框290，第二卡勾29322用于与面板281的卡合结构2811配合，使得面板281固定于背框290。
在本发明实施方式中，将至少两个主拼接件以拼接形式进行连接，可以使背框的模具结构简单，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生产成本，同时还因为背框的镂空结构而利于散热；此外，用于设置光源的主拼接件采用散热能力较好的材料，进一步利于散热；进一步地，主拼接件侧壁远离光源的另一表面设置有卡勾，卡勾分别与前框和面板上的卡合结构配合，从而固定前框和面板于背框，方便装配前框和面板。
本发明还提供一种制造平板显示装置的背框的模具实施方式，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。
如图22所示，本发明还提供一种制造平板显示装置的背框的方法实施方式，该方法包括以下步骤：
步骤501：制作至少两个主拼接件，所述至少两个主拼接件拼接形成背框的主框架，其中，至少一主拼接件向上折弯以设置光源，所述至少两个主拼接件中包括用于设置光源的主拼接件，光源设置于用于设置光源的主拼接件的向上折弯的侧壁的一表面，并且侧壁远离光源的另一表面设置有向下的卡勾，用于设置光源的主拼接件具有第一散热能力，至少两个主拼接件中其余不用于设置光源的一个或以上主拼接件具有第二散热能力，第一散热能力大于第二散热能力；
在本发明实施方式中，用于设置光源的主拼接件的材料可选为散热性能较好的铝挤，至少两个主拼接件中其余不用于设置光源的一个或以上主拼接件的材料可选为散热性能一般的镀锌钢件。当用于设置光源的主拼接件的材料选为铝挤时，铝挤材料不能通过冲压形成用于设置光源的主拼接件的侧壁远离光源的一表面上的卡勾。
请参阅子步骤5011与5012，子步骤5011与5012详细说明用于设置光源的主拼接件的材料选为铝挤时，该主拼接件的卡勾的制作方法。请再次参阅图17-21，制作用于设置光源的主拼接件的的卡勾的步骤具体包括:
子步骤5011：使铝挤材料通过铝挤挤出制程形成设置光源的主拼接件材料，其中，铝挤挤出的主拼接件材料包括向上折弯的侧壁和自侧壁向远离光源的另一表面延伸起而形成的倒L型待加工块；
子步骤5012：铣掉倒L型待加工块下端靠内侧部分，从而形成卡勾；
在本发明实施方式中，卡勾的数量为两个，分别为第一卡勾和第二卡勾，其中，第一卡勾用于与前框的卡合结构配合，使得前框固定于背框，第二卡勾用于与面板的卡合结构配合，使得面板固定于背框。
步骤502：将至少两个主拼接件进行拼接。
其中，背框的拼接结构与上述实施方式中的背框拼接结构相同，此处不再一一赘述。
在本发明实施方式中，制作至少两个主拼接件，至少两个主拼接件拼接形成背框的主框架，可以使背框的模具结构简单，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生产成本；此外，用于设置光源的主拼接件采用散热能力较好的材料，进一步利于散热；进一步地，主拼接件侧壁远离光源的另一表面设置有卡勾，卡勾分别与前框和面板上的卡合结构配合，从而固定前框和面板于背框，方便装配前框和面板。
在本实施方式中，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，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。
当然，背光系统21还可以是前述任一背光系统实施方式中的结构。
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，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为上述各实施方式的背光系统，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。背光系统32还可以是前述任一背光系统实施方式中的结构，在此不再赘述。
本发明还提供一种等离子显示装置40，如图26所示，等离子显示装置40包括等离子显示面板41以及背框42，背框42设置在等离子显示面板41的背面。其中，背框42可以为前述任一实施方式的背框，在此也不再赘述。
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。
本发明又提供一种平板显示装置实施方式。如图27所示，平板显示装置60包括前框61、面板62以及背光系统63。背光系统63包括光源631、匀光机构632以及背框633。背框633承载光源631和匀光机构632，面板62夹持于前框61和背框633之间，前框61设有向下延伸的侧壁611，并且前框61的侧壁611设有适配背框633的卡勾6331的窗口612，背框633的卡勾6331穿过前框61的侧壁611上的窗口612，将前框611卡固。其中，背框的拼接结构与上述实施方式中的背框拼接结构相同，以处不再一一赘述。
在本发明实施方式中，拼接形成的背框，可以使背框的模具结构简单，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生产成本；背框设置有卡勾，并且与前框的侧壁设置的窗口适配，背框的卡勾穿过前框的侧壁上的窗口，将前框卡固，方便装配前框。
以上所述仅为本发明的实施方式，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。
