【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。
继续参阅图3,在本实施例中,至少两个主拼接件,即第一主拼接件261和第二主拼接件262,第一主拼接件261包括拼接部2611和拼接部2612,第二主拼接件262包括拼接部2621和拼接部2622,拼接部2611设置有对位标识A,拼接部2612设置有对位标识B,与拼接部2611拼接的拼接部2621相应设置有对位标识A,与拼接部2612拼接的拼接部2622相应设置对位标识B。相关人员在利用拼接部进行对第一主拼接件261和第二主拼接件262进行拼接时,只需要注意拼接部的对位标识是否一致即可,可以减少耗时、提高效率。当然,除使用字母作为对位标识之外,还可以使用数字、图形等作为对位标识,此处不作过多限制。
下面以拼接部2611与拼接部2621设有相适配的防呆结构作为对位标识为例进行说明。
下面以拼接部2611和拼接部2621为例进行说明。
参阅图4-图8,图4-图8是对图3所示拼接部不同实施例的分解示意图。拼接部2611与拼接部2621的设计为非轴对称图形时,可以满足防呆需求。具体的,参阅图4,拼接部2611设有凹槽,在凹槽设置一缺角,使其成为非轴对称结构,相应地,拼接部2621是第二主拼接件262的一端,拼接部2621对应位置设置与拼接部2611的缺角适配的另一缺角,两缺角配合形成防呆结构。缺角可为三角形接口缺角(如图4所示),缺角也可为矩形接口缺角、圆形接口缺角或锯齿形接口缺角。当然,缺角的形状、大小、数目和位置可视具体情况设计,只要使相关人员能够简单、不出错就能拼接好背框即可,此处不作过多限制。

一起参阅图9,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、三主拼接件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10,图10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10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9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。
请参见图11,图11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11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。
请参见图12,图12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12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。
请参见图13,图13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9-图13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14,图14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14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的一端表面至少设有拼接部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。
请参见图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。如图15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。
请参见图16,图16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。如图16所示,为方便另一方向上背框23尺寸的可选,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,如图17所示,图17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12所示。
此外,如图18所示,图18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19,图19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20,图20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15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16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,利用拼接部将至少两个主拼接件进行拼接。
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。

当然,背光系统21还可以是前述任一背光系统实施例中的结构。
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23所示,图23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。背光系统32还可以是前述任一背光系统实施例中的结构,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,在至少两主拼接件的拼接部设置相适配的防呆结构后进行拼接,满足防呆设计,能够帮助相关人员简单、不出错就能拼接好背框,减少误操作、提高效率。
