随着显示技术的不断发展，人们对显示装置的需求不断提高。其中，显示装置可根据发光方式的不同分为直下式和侧入式。直下式显示装置的背光是将灯条均匀地分布在背板上，其亮度均匀，但需要灯条的数量较多，比较耗电并且会造成显示装置厚度较厚，而侧入式显示装置的背光是将灯条安装在显示装置的边框处使得光源从侧面发出，其使用灯条数量较少，比较省电并且可使显示装置更为轻薄。
但是，相关技术中的侧入式显示装置的灯条所发出的热量是通过散热器实现散热，然而散热器本身成本较高，且散热器需要通过螺钉固定在显示装置的背板上，使得显示装置的物料成本和装配人工成本都较为昂贵。
为解决显示装置成本较高的问题，本申请实施例提供一种背板和显示装置。以下将结合附图进行详细说明。
请参阅图1，图1是本申请实施例提供的背板的第一种结构示意图。其中，该背板20应用于显示装置10，该显示装置10可以为电视，也可以为具有显示功能的一体机，如一体式电脑等，在此不作具体限定。显示装置10为侧入式显示装置。
其中，背板20可以包括主体部201和第一弯折部202，第一弯折部202可为双层结构，即包括相互叠加的第一层2021和第二层2022。当显示装置10处于竖直放置状态时，第一弯折部202可位于背板20的底部，此时，第一层2021可位于靠近背板20内部结构一侧，即内层，第二层2022可位于相对于第一层2021背离背板20内部结构一侧，即外层。灯条30设置于第一层2021背离第二层2022一侧，即设置于背板20内部结构一侧。
需要说明的是，侧入式背板20的灯条30设置在入光侧，灯条30需要接触式散热。相关技术中，由于背板的底部的弯折区域为单层结构，其厚度较薄，而灯条与该弯折区域接触式散热的距离较近，而为了实现良好的散热效果，需要通过增加散热器如散热铝条，具体为将灯条粘贴在散热器上进行固定和散热，从而增加了散热器的装配成本和材料本身成本。
而本实施例中，通过在背板20的第一弯折部202设置双层结构，将灯条30设置在第一弯折部202中第一层2021背离第二层2022一侧，增加与灯条30接触的材料厚度，并增加了接触式散热的距离，从而在无需增加散热器的基础上保证显示装置10良好的散热效果。进而节省了成本较高的散热器及装配散热器所需要的人工成本等，降低了显示装置10整机成本。
请继续参阅图1，背板20还可以包括第二弯折部203、第三弯折部204和第四弯折部205。第一弯折部202、第二弯折部203、第三弯折部204和第四弯折部205首尾可依次连接，从而如长方形的背板20的轮廓。其中，第一弯折部202与第三弯折部204相对设置，由于第一弯折部202位于背板20的底部，则第三弯折部204位于背板20的顶部，第二弯折部203与第四弯折部205相对设置，则第二弯折部203与第四弯折部205分别位于背板20的两个侧边。
其中，第一弯折部202、第二弯折部203、第三弯折部204和第四弯折部205可分别与主体部201粘接形成，或者通过其他方式固定连接。第一弯折部202、第二弯折部203、第三弯折部204和第四弯折部205相对于主体部201的弯折方向相同，从而避免弯折方向不同造成的背板20厚度增加的问题。
为了提高主体部201与第一弯折部202、第二弯折部203、第三弯折部204和第四弯折部205之间的连接稳定性，可以将第一弯折部202、第二弯折部203、第三弯折部204和第四弯折部205与主体部201一体成型。具体可以为通过将背板20的四边分别朝同一方向弯折成型，弯折的部分分别形成第一弯折部202、第二弯折部203、第三弯折部204和第四弯折部205，而未弯折的部分则为主体部201，从而提高背板20整体的结构稳定性。
需要说明的是，由于位于背板20底部的第一弯折部202为双层结构，而背板20本身是单层结构，为了形成双层结构，需要首先将背板20底部的一部分区域向内弯折180度，以使背板20处于底部的一部分在未形成弯折部之前即为双层结构，随后将该背板20如上所述四边朝同一方向弯折形成第一弯折部202、第二弯折部203、第三弯折部204和第四弯折部205，此时，第一弯折部202是由背板20形成双层结构的部分弯折后形成，因此第一弯折部202也为双层结构。而第二弯折部203、第三弯折部204和第四弯折部205是由背板20处于单层结构的区域弯折形成，因此第二弯折部203、第三弯折部204和第四弯折部205也为单层结构。其中，背板20的四个侧边可朝同一方向弯折90度以形成第一弯折部202、第二弯折部203、第三弯折部204、第四弯折部205以及主体部201。
需要说明的是，请参阅图2，图2是图1所示的背板的局部放大示意图。其中，在背板20向内弯折180度形成双层结构的过程中，为了固定该双层结构，可以在背板20的双层结构区域设置多个铆接点40，通过铆接实现双层结构的固定；也可以通过焊接固定双层结构；为减少工艺还可以将该双层区域通过一次冲压成型。
请参阅图3和图4，图3是本申请实施例提供的背板的第二种结构示意图，图4是图3所示的背板沿A-A方向的剖面局部放大示意图。如上所述，第一弯折部202为双层结构，第二弯折部203、第三弯折部204和第四弯折部205为单层结构，因此，第一弯折部202的厚度为第二弯折部203、第三弯折部204和第四弯折部205厚度的二倍，但是双层结构在成型过程中二者之间会存在一定的间隙误差，因此加上间隙的厚度使得第一弯折部202的厚度为第二弯折部203、第三弯折部204和第四弯折部205厚度的至少二倍。为了减少双层结构之间的间隙误差，可以在背板20的双层结构的区域设置多个自铆点50，通过自铆点50的铆接控制双层结构之间间隙的大小；还可以通过点焊的工艺实现间隙大小的控制，具体在此不作具体限定。
其中，第一弯折部202的双层结构中第一层2021和第二层2022之间的间隙小于0.2毫米。背板20弯折所形成的第一弯折部202、第二弯折部203、第三弯折部204和第四弯折部205的宽度在50-500毫米之间。
由于背板20的第一弯折部202与灯条30接触式散热，为了提高散热效果，可以将背板20的材质设置为镀锌钢板、不锈钢板和铝板中的至少一种，当然也可以为其他具有良好传热性能的金属材料，在此不作具体限定。通过设置双层散热结构，省去了散热器，减少了制造成本及制造工艺，并且通过如上述几种散热材料的双层结构保持良好的散热效果。
需要说明的是，显示装置10还可以包括中框、光学膜片、装置条和液晶玻璃等。其中，中框的作用为固定光学膜片和提供放置液晶玻璃的平台，中框可通过背板20上的卡扣或者螺孔与背板20紧固；装置条设置在液晶玻璃的侧边及中框侧边，能够将中框及液晶玻璃包裹固定；液晶玻璃设置于光学膜层的上方用于出光。
背板20还可以包括前框，由于入光侧的背板20需要设计固定前框的螺孔等结构，为防止螺钉打入背板20腔体内造成入光异常等问题，因此在背板20上螺孔60的位置设计向外打凸的凸台结构，并在该凸台结构上设置有多个螺孔60，该凸台结构设置在第一弯折部202背离背板20腔体内的一侧，若第一弯折部202的第一层2021为内层，第二层2022为外层，则将凸台结构设置在第一层2021背离第二层2022一侧，即多个螺孔60设置在第一层2021背离第二层2022一侧；若第一弯折部202的第一层2021为外层，第二层2022为内层，则将凸台结构设置在第二层2022背离第一层2021一侧，即多个螺孔60设置在第二层2022背离第一层2021一侧。从而使得背板20可通过多个螺孔60与前框螺接固定。
需要说明的是，在第一弯折部202与前框螺接固定后，前框的外侧还可以设置将显示装置10固定在水平台上的固定装置，如底座等，而相关技术中由于弯折部为单层结构，其厚度较薄，无法之间与前框连接，或者与前框连接之后无法通过前框直接与底座连接，因此需要在前框与底座之间或者弯折部与前框之间增加底座支撑结构，这样便增加了制造工艺，从而增加了制造成本。而本实施例中通过在底部的第一弯折部202设置双层结构，其厚度较厚，使得材料刚性足以支撑与前框直接连接，或者支撑前框与底座直接连接，双层结构的刚性及结构强度能够保证显示装置10在水平台上放置，从而省去了增加底座支撑的制造工艺，减少了制造成本。
另外，背板20还可以包括多条连接线，该多条连接线能够连接显示装置10中的多个功能器件如灯条30等，形成显示装置10的内部电路结构，但为了减少多条连接线在背板20内部的绕线长度及绕线占用的内部空间问题，可以通过设置缺口使得多条连接线能够穿过，减少绕线。比如可以在第一弯折部202的第一层2021设置多个第一缺口、第二层2022设置多个第二缺口，并且多个第一缺口中的一个第一缺口具有相对设置的一个第二缺口，以保证一条连接线能够依次穿过一个第一缺口和一个第二缺口，实现穿过第一弯折部202，如与灯条30连接的连接线可分别穿过第一缺口和第二缺口并与其他功能器件连接，减少绕线占用的背板20的内部空间。
由上可知，本实施例提供的背板20包括主体部201和第一弯折部202，第一弯折部202包括相互叠加的第一层2021和第二层2022，主体部201和第一弯折部202一体成型。通过设置在背板20上设置具有双层结构的第一弯折部202与设置在第一弯折部202一侧的灯条30实现接触式散热，通过增加背板20的厚度从而增加了接触式散热所传热的距离，进而提高了散热效果，并且无需设置散热器为灯条30散热，省略了散热器，降低了显示装置整机的制作成本。另外，由于第一弯折部202的双层结构设置在背板20的底部，双层结构相对于单层结构的刚性增加，具有与底座相互连接的结构强度，从而无需增加第一弯折部202与底座之间的底座支撑结构来提高结构强度，因此，减少了制备底座支撑结构的制造工艺，进一步减少了显示装置10整机的制造成本。
另外，本申请实施例还提供了一种显示装置，请参阅图5，图5是本申请实施例提供的显示装置的结构框图。该显示装置10可以为电视，也可以为具有显示功能的一体机，如一体式电脑等，在此不作具体限定。该显示装置10包括背板20和灯条30。
其中，背板包括主体部和第一弯折部，第一弯折部可为双层结构，即包括相互叠加的第一层和第二层，主体部和第一弯折部一体成型；灯条30设置于第一层背离第二层一侧，即设置于背板20内部结构一侧；中框的作用为固定光学膜片和提供放置液晶玻璃的平台，中框可通过背板上的卡扣或者螺孔与背板紧固；装置条设置在液晶玻璃的侧边及中框侧边，能够将中框及液晶玻璃包裹固定；液晶玻璃设置于光学膜层的上方用于出光；在背板上在螺孔的位置设计向外打凸的凸台结构，并在该凸台结构上设置由多个螺孔，该凸台结构设置在第一弯折部背离背板腔体内的一侧，从而使得背板可通过多个螺孔与前框螺接固定，以保证显示装置10的整体结构稳定性。
本申请实施例提供的背板应用于显示装置，背板包括主体部和第一弯折部，第一弯折部包括相互叠加的第一层和第二层，主体部与第一弯折部一体成型。本申请通过设置双层背板为灯条散热，提升了显示装置的结构强度，无需增加支撑结构进行支撑，降低了显示装置整机的制作成本。
