在这里专用的词“示例性”意为“用作例子、实施例或说明性”。这里作为“示例性”所说明的任何实施例不必解释为优于或好于其它实施例。
另外，为了更好的说明本发明，在下文的具体实施方式中给出了众多的具体细节。本领域技术人员应当理解，没有某些具体细节，本发明同样可以实施。在另外一些实例中，对于本领域技术人员熟知的方法、手段、元件和电路未作详细描述，以便于凸显本发明的主旨。
实施例1
以下结合图1、图2和图3为例，来说明本实施例的具体实现方式，包括不同的示例，这些具体实现方式和示例仅为了便于理解，而不以任何方式限制本发明。
示例1
图1示出根据本发明一实施例的一个示例的电视机背板的结构图。如图1所示，该电视机背板主要包括：碳纤维板1；第一粘合剂层2，位于所述碳纤维板1的一侧；以及第一金属板3，所述第一金属板3通过所述第一粘合剂层2与所述碳纤维板1粘接。
本示例中，通过第一粘合剂层2使碳纤维板1与第一金属板3粘接，以构成由碳纤维板1、第一粘合剂层2和第一金属板3复合而成的电视机背板，在保证了美观和强度的前提下，使电视机背板更薄。
碳纤维板1
本示例中，碳纤维板1可以作为电视机背板的一部分，为电视机提供支撑作用。碳纤维板1可以由碳纤维构成，碳纤维是一种含碳量在95％以上的高强度、高模量纤维的新型纤维材料，它是由片状石墨微晶等有机纤维轴向 方向堆砌而成，经碳化及石墨化处理而得到的微晶石墨材料。碳纤维具有密度低、强度高、导电导热性能好、电磁屏蔽性好、耐刮、耐腐蚀、热膨胀系数小等优点。碳纤维板1的一侧粘有第一粘合剂层2，以便于通过第一粘合剂层2将碳纤维板1与第一金属板3进行粘接，从而构成电视机背板。
在一种可能的实现方式中，碳纤维板1可以由多层碳纤维布浸渍树脂后固化而成。其中，碳纤维布的层数可以决定碳纤维板1的厚度。碳纤维板1的厚度可以根据需要进行设计。例如，以55寸以内的电视机为例，碳纤维板1的厚度可以设计为0.8mm～1.2mm，例如可以设计为1mm。碳纤维板1的厚度可以由电视机的尺寸、碳纤维板1自身的密度、强度、以及第一金属板3的类型等因素来确定，本发明对此不作限制。
碳纤维板1可以是本领域技术人员已知的利用碳纤维制成的碳纤维板，然而，本领域技术人员可以根据需要选择适当的方式来制作碳纤维板，本发明对碳纤维板1中的各物质含量及制作方法等，均不作限制。碳纤维板1还可以是本领域技术人员能够从市场购买到的碳纤维板，本发明对此不作限制。
由于碳纤维板1的低密度和强度高的优良特性，在具有相同强度和表面积的情况下，碳纤维板的厚度可以相比于金属板减小很多。此外，由于碳纤维还具有良好的导电导热和电磁屏蔽等性能，通过采用碳纤维板作为电视机背板的一部分，可以在不影响电视机背板的功能的情况下，有效地减小电视机背板的厚度。
第一粘合剂层2
本示例中，第一粘合剂层2可以位于碳纤维板1的一侧，或者说可以位于碳纤维板1与第一金属板2之间，其作用可以是使碳纤维板1与第一金属板3粘接，从而成为一个复合结构，以便作为电视机背板。
在一种可能的实现方式中，第一粘合剂层2的厚度可以为0.01mm～0.03mm。第一粘合剂层2的厚度可以根据电视机背板的导电导热等 性能，以及碳纤维板1与第一金属板3粘接后的牢固性等因素来进行设计。
第一粘合剂层2可以是粘合剂对碳纤维板1和第一金属板3进行粘接，固化后而形成的。其中粘合剂可以是本领域技术人员已知的可以将非金属结构与金属结构进行粘接的粘合剂，例如可以是氟碳树脂涂料等。
第一金属板3
本示例中，第一金属板3与碳纤维板1可以通过第一粘合剂层2进行粘接，以构成由第一金属板3、第一粘合剂层2和碳纤维板1复合而成的电视机背板。
在一种可能的实现方式中，第一金属板3的面积可以小于碳纤维板1的面积，也就是说第一金属板3可以作为电视机背板的外观面的一部分，换言之，呈献给用户的电视机背板的外观面可以既包括金属板面也包括碳纤维板面，图2示出根据本发明一实施例的一个示例的电视机背板的外观示意图。如图2所示，用户可以同时观察到第一金属板3和碳纤维板1。用户观察到的第一金属板3的面积与碳纤维板1的面积可以根据需要进行设计，例如，可以设置第一金属板3的面积占整个电视机背板面积的五分之一，碳纤维板1的面积占整个电视机背板面积的五分之四。在一种可能的实现方式中，可以使第一金属板3与碳纤维板1的上部重叠，即第一金属板3覆盖碳纤维板1的上部而露出碳纤维板1的下部，使第一金属板3处于上方且碳纤维板1处于下方的电视机背板结构呈现给用户。针对金属板3，可以对其进行工艺造型，增加美观度；针对碳纤维板1，由于处于电视机背板的下方，较不受用户关注，其工艺造型可以不如第一金属板3那样美观且细致，进而可简化工艺难度。
针对第一金属板3的面积小于碳纤维板1的面积的情况，在一种可能的实现方式中，第一金属板3可以嵌入的方式与碳纤维板1粘接，例如碳纤维板1的一部分(例如上部)的厚度可小于另一部分(例如下部)的厚度，第一金属板3可通过第一粘合剂层2与碳纤维板1的厚度较小的部分粘接，从而构成例如图3a-3c所示的结构。在另一种可能的实现方式中，第一金属板3可以非 嵌入的方式与碳纤维板1粘接。例如，碳纤维板1可为厚度基本均匀的碳纤维板，第一金属板3可通过第一粘合剂层2与碳纤维板1的一部分(例如上部)粘接(如图3d所示)。
在一种可能的实现方式中，第一金属板3的表面可与所述碳纤维板1的未与所述第一金属板3重叠部分的表面在同一平面上(例如图3a所示)，也就是说，第一金属板3与碳纤维板1重叠后呈现给用户的面是一个整体的平面结构，各部分(包括第一金属板3和碳纤维板1)均处于同一平面上，不存在凸起或者凹陷，从而进一步提高电视机背板外观面的美观度。在另一种可能的实现方式中，第一金属板3的表面可与碳纤维板1的未与所述第一金属板3重叠部分的表面不在同一平面上。换言之，第一金属板3的表面可能高于或低于碳纤维板1的未与第一金属板3重叠部分的表面(如图3b、图3c、3d所示)。
在另一种可能的实现方式中，第一金属板3的面积可大于或者等于碳纤维板1的面积，也就是说第一金属板3可以作为整个电视机背板的外观面，换言之，呈献给用户的电视机背板的外观面可以仅为金属板面。本领域技术人员还可以根据实际需要对第一金属板3所处的外观面进行附加功能设计。后文将对其进行详述。
本示例中的第一金属板3可以根据需要进行选择，第一金属板3的材料可以是本领域技术人员已知的可以作为电视机背板的金属材料，例如可以是铝、铁、钢或者合金等。第一金属板3还可以是本领域技术人员已知的可以作为电视机背板的金属板，例如可以是覆膜板VCM或彩涂板PCM等。
在一种可能的实现方式中，如果选择覆膜板VCM或彩涂板PCM作为电视机背板，可以对板材的表面进行工艺处理，以获得非常优秀的外观色彩及图案造型等装饰性功能，例如拉丝、压花、预涂颜色、贴膜等。对于贴膜，还可以根据选择贴覆不同的膜，以实现不同的附加功能。例如可以贴覆具有自清洁功能的膜，以使电视机背板具有自清洁的功能；又例如可以贴覆具有 防静电功能的膜，以使电视机背板具有防静电的功能；还例如，可以贴覆具有高耐热、书写等功能的膜，以使电视机背板具有相应的附加功能。
第一金属板3的厚度可以根据本领域技术人员的实际需要进行设计，例如，在本示例中，以55寸的电视机为例，第一金属板3的厚度可以小于0.4mm。第一金属板3的厚度可以根据电视机的尺寸、第一金属板3自身的材质、以及碳纤维板1的类型等因素来确定，本发明对此不作限制。
在一种可能的实现方式中，碳纤维板1和第一金属板3可以通过粘合剂采用适当的复合方式进行贴合，以获得由碳纤维板1、第一粘合剂层2、第一金属板3构成的复合结构的电视机背板。例如，可以采用刷胶的方式，在碳纤维板1与第一金属板3之间将粘合剂涂布均匀，并使二者贴合，待粘合剂固化后，碳纤维板1、第一粘合剂层2、以及第一金属板3可以成为一个整体的复合结构，从而作为电视机背板。本领域技术人员还可以采用其他的方式使碳纤维板1与第一金属板3进行粘接，本发明对此不作限制。
在本示例的一个子示例中，由碳纤维板、粘合剂层和覆膜板VCM或彩涂板PCM构成的复合结构作为电视机背板，具有强度高、超薄、美观、重量轻、功能性强等优点。
示例2
图4示出根据本发明一实施例的另一个示例的电视机背板的结构图，其中用相同的附图标记表示的部件是相似的。如图4所示，电视机背板除包括有碳纤维1、第一粘合剂层2、第一金属板3外，还可以包括位于碳纤维板1的另一侧的第二粘合剂层4，以及第二金属板5，其中第二金属板5可以与碳纤维板1通过第二粘合剂层4粘接。
本示例中，通过第一金属板3、第一粘合剂层2、碳纤维板1、第二粘合剂层4和第二金属板5复合而成三明治结构的电视机背板，在保证了美观和强度的前提下，使电视机的背板更薄。
在一个可能的实现方式中，以55寸电视机为例，在由第一金属板3、第一粘合剂层2、碳纤维板1、第二粘合剂层4和第二金属板5构成的复合结构中，碳纤维板1的厚度可以为0.6mm-0.8mm。
第二粘合剂层4
本示例中，第二粘合剂层4可以位于碳纤维板1的另一侧，即与第一粘合剂层2相反的一侧，以使第二金属板5与碳纤维板1粘接，从而使第一金属板3、第一粘合剂层2、碳纤维板1、第二粘合剂层4和第二金属板5成为一个整体的复合结构，以便作为电视机背板。
在一种可能的实现方式中，在由第一金属板3、第一粘合剂层2、碳纤维板1、第二粘合剂层4和第二金属板5构成的复合结构中，第一粘合剂层2和第二粘合剂层4的厚度可以为0.01mm～0.03mm，第一、第二粘合剂层的厚度可以根据电视机背板的导电导热等性能，以及与碳纤维板1等粘接后的牢固性等因素来进行设计，两者可以相同也可以不同。
第二粘合剂层4可以是粘合剂对碳纤维板1和第二金属板5进行粘接，固化后而形成的。其中粘合剂可以是本领域技术人员已知的可以将非金属结构与金属结构进行粘接的粘合剂，例如可以是氟碳树脂涂料等。构成第二粘合剂层所采用的粘合剂可以与构成第一粘合剂层所采用的粘合剂相同，也可以不同，本发明对此不作限制。
第二金属板5
本示例中，第二金属板5与碳纤维板1可以通过第二粘合剂层4进行粘接，以构成由第一金属板3、第一粘合剂层2、碳纤维板1、第二粘合剂层4和第二金属板5复合而成的电视机背板。如果以碳纤维板1作为基准，第二金属板5与第一金属板3可以处于相对的位置，例如可以选择第一金属板3作为电视机背板的外观面，则第二金属板5为非外观面，所以第二金属板5可以不具有外观功能，所述外观功能可以是例如前一示例所述的拉丝、压花、预涂颜色、 贴膜等功能。然而，第二金属板5也可以具有外观功能，本发明对此不作限制。
通过采用由第一金属板3、第一粘合剂层2、碳纤维板1、第二粘合剂层4和第二金属板5复合而成的结构作为电视机背板，使第二金属板5处于碳纤维板1与电视机内部结构之间，也就是说可以采用第二金属板5使碳纤维板1与电视机内部隔离，以有效地改善碳纤维板1与电视机内部结构直接接触摩擦而产生静电的问题，进而改善静电对电视机性能的影响。
本示例中，第二金属板5可以根据需要进行选择，第二金属板5的材料可以是本领域技术人员已知的可以适合于作为电视机背板的金属材料，例如可以是铝、铁、钢或者合金等，其可与第一金属板3的材料相同也可以不同。本发明对此不作限制。第二金属板5的厚度可以根据本领域技术人员的实际需要进行选择，例如，以55寸的电视机为例，在由第一金属板3、第一粘合剂层2、碳纤维板1、第二粘合剂层4和第二金属板5构成的复合结构中，第一金属板3和第二金属板5的厚度可以为0.2mm～0.4mm，二者的厚度可以相同也可以不同。第一、第二金属板的厚度可以根据电视机的尺寸，第一、第二金属板自身的材质、类型、碳纤维板1的类型等因素来确定。本发明对此不作限制。
本示例中，碳纤维板1与第二金属板5通过第二粘合剂层4进行粘接的方式可以与示例1中碳纤维板1与第一金属板3通过第一粘合剂层2进行粘接的方式相同，也可以不同。此外，对于采用何种方式进行粘接，本发明对此不作限制。
采用上述示例的方案，在一个示例性的应用场景中，43寸～65寸的电视机背板的厚度可以为1.2mm左右，相比于现有技术中的电视机背板，厚度可减薄50％～70％(例如常规的铝塑板厚度：65寸为3.0mm～3.5mm，43寸～55寸为2.3mm)。此外，由于这种背板本身具有足够的强度，不需要设计加强筋， 可以呈献给用户整个背板为全平面结构，改善了用户的视觉效果。
实施例2
本发明的另一实施例还提出了一种电视机，该电视机包括有实施例1所述的电视机背板。
本实施例通过采用由碳纤维板、粘合剂层和金属板组成的复合结构替代传统的电视机背板，可以在保证了美观和强度的前提下，使电视机的背板更薄。
在本实施例的一个示例中，包括实施例1所述的电视机背板的电视机可以是平面或曲面的LCD电视。在本实施例的另一个示例中，包括实施例1所述的电视机背板的电视机可以是OLED电视。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以所述权利要求的保护范围为准。
