如图1、图2、图3所示，背板包括支架11及基板12。其中支架11与所述基板12可拆卸地固定在一起。但是，可以理解的是，本发明并不限制于此，根据本发明的实施例的背板还可以包括其它必要的部件。
具体地，支架11包括支架底部111及设置于支架底部111侧边的支架侧壁部112。支架底部111具有开口113，支架底部111用于与基板12连接，支架底部111的开口113应可容纳装于基板12上的发光部件穿过。支架侧壁部112远离支架底部111的一端用于与中框连接。
根据本发明的一种实施方式，支架侧壁部112包括自支架底部111的侧边 向外翻折形成的第一部分1121、设置于第一部分1121的远离支架底部111的一端且与支架底部111平行的第二部分1122、设置于第二部分1122的远离第一部分1121的一端且与第二部分1122垂直的第三部分1123。第一部分1121是自支架底部111的侧边向外翻折形成，因此，第一部分1121围绕支架底部111形成一内部腔体，形成可容纳发光部件的空间。第二部分1122与支架底部111平行，第二部分111用于支撑其上的导光板、光学膜片等组件。第三部分1123与第二部分1122垂直，相当于支架11的最侧边，主要用于与中框进行连接。
作为其中一种实施方式，在第三部分1123的外表面设置有用于与中框连接的连接部114。根据本发明的一种优选的实施方式，连接部114可为凸起结构和/或卡扣。可以理解的是，中框与所述第三部分1123相对的表面上也对应设置有连接部，该连接部与第三部分1123的连接部114相对应可为对应的凹入结构和/或结构。但本发明对此不作限制，其它合适的连接结构亦可应用于连接部114的结构设计。
基板12可拆卸地封闭开口113。参照图2，其中，基板12面向支架11的表面用于安装发光部件。基板12背向支架11的表面用于安装散热部件。发光部件工作时会产生大量的热量，也就是说，基板11的一面安装有发热源，基板11的另一面安装有散热部件，故决定液晶显示装置的散热能力的主要部件是基板及设置在基板上的散热部件。通常散热部件70采用散热鳍片及风扇组成。参照图3，散热鳍片的厚度a1、高度a2、间距a3均会影响散热能力。此外，基板的厚度a4也是影响散热能力的一个方面。而基板12是可拆卸地封闭开口113，也就是说，在不同散热条件下，仅需设计适合该散热条件的基板12及散热结构，对应更换上适合该散热条件的基板12，
即可应用于不同的散热环境。而基板12的模组设计远远比背板的模组设计简单，所需成本也较低，因此该基板12结构的设计可有效地解决不同环境下的散热问题，且成本较低。
根据本发明的一种实施方式，基板12通过螺丝可拆卸地固定在支架底部111。此外，基板12还可以通过焊接的方式可拆卸地固定在支架底部111。当然本发明并不限制于此，基板12还可以采用其它合适的可拆卸地方式与支架 底部111固定在一起。
此外，由于基板12用于将发光部件产生的热量传导给散热部件，因此根据本发明的一种实施方式，基板12采用传热性能较好的金属。作为其中一种实施方式，基板12采用铝制成。作为其中一种实施方式，基板12也可采用铜制成。但是，本发明并不限制于此，基板12还可以还采用其它传热性能较好的材料制成。
图4示出了背光模组的结构示意图。
如图4所示，背光模组包括上述的背板10、发光部件20、散热部件70、导光板30、光学模组40、中框50及前框60。但是可以理解的是，本发明并不限制于此，根据本发明的实施例的背光模组还可以包括其它必要的部件。
具体地，背板10为上述基板12可进行拆换的背板10。基板10面向支架11的表面上设置有发光部件20，发光部件20用于提供背光模组所需的光源，同时，发光部件20工作时会产生大量的热量。作为其中一种实施方式，基板12背向支架11的表面上设置有散热部件70，散热部件70用于将基板12传导过来的热量进行散发，可以理解的是，散热部件70的结构与基板12的结构相匹配以适应不同温度要求的背光模组的使用。支架侧壁部112上依次设置有导光板30、光学膜片40、中框50及前框60。
根据本发明的一种实施方式，中框50包括中框底部51和设置于中框底部51侧边的中框侧壁部52。中框侧壁部52与支架侧壁部112连接。作为其中一种实施方式，中框侧壁部52与第三部分1123连接。作为其中一种实施方式，中框侧壁部52面向第三部分1123的外表面的表面上设置有与第三部分1123的连接部114相对应的连接部。连接部可以是相对应的凹入部和/或卡扣结构，本发明对此不作限制。作为其中一种实施方式，中框50选用塑胶材料制成，但本发明对此不作限制，中框还可以选用其它合适的材料制成。
根据本发明的实施例的背光模组，仅需通过更换与温度条件相匹配的基板10及散热部件70即可适用于多种温度条件，可有效地解决背光模组适用于不同温度条件的难题且极大地节约了成本。
图5示出了液晶显示装置的结构示意图。
如图5所示，根据本发明的实施例的液晶显示装置包括液晶面板200及上述的背光模组100。但可以理解的是，本发明并不限制于此，根据本发明的实施例的液晶显示装置还可以包括其它必要的部件。
具体地，液晶面板200与背光模组100相对设置，背光模组100提供显示光源给液晶面板200以使液晶面板200显示影像。
本发明的液晶显示装置，仅需通过更换与温度条件相匹配的基板12及散热部件70即可适用于多种温度条件，可有效地解决液晶显示装置适用于不同温度条件的难题且极大地节约了成本。
本发明的以上实施例仅仅是示例性的，而本发明并不受限于此。本领域技术人员应该理解：在不脱离本发明的原理和精神的情况下，可对这些实施例进行改变，其中，本发明的范围在权利要求及其等同物中限定。
