技术领域
本公开的实施例涉及显示器领域，具体涉及一种背光模组及其组装方法，以及一种显示装置。
背景技术
液晶电视主要由液晶显示器和控制板以及其它部件组成，液晶显示器主要包括了液晶面板和背光模组。背光源种类可分为侧出光式背光源和直下式背光源。近年来，为了降低液晶电视成本，直下式背光源被更多的生产商所采用。与侧出光式背光源相比，直下式背光源的成本优势非常明显。
直下式背光模组包括灯条与背板。目前直下式背光模组的灯条与背板的常用固定方式有如下三种：第一种方式是采用双面胶带粘贴，如图1中所示；第二种固定方式是螺丝锁附，如图2中所示；第三种固定方式是在短边上采用弹性嵌合方式，如图3中所示。这三种固定方式在现行生产中报出一些问题，很难根本解决。对于采用双面胶带粘贴的第一种固定方式，在重工时，容易出现残胶残留，灯条变形。对于采用螺丝锁附的第二种固定方式，工时成本较长，且螺丝在锁附时，容易出现铁屑。对于采用短边弹性嵌合的第三种固定方式，灯条与背板嵌合后，重工时需要借助辅助工具，且容易造成灯条变形，业界使用比较少。
可见，本领域中需要一种能够克服上述现有技术的缺点的改进的背光模组解决方案。

在本公开的另一个方面，提供了一种背光模组，包括背板和灯条，其中，所述背板上设置有固定结构，所述固定结构包括弹性压片，该弹性压片上设置有孔；并且所述灯条上设置有能与所述弹性压片上的孔匹配的突出部。
在本公开的另一个方面，提供了一种显示装置，包括：显示面板，以及根据本公开的实施例的背光模组。
在本公开的另一个方面，提供了一种背光模组的组装方法，包括：制备背板，包括在该背板上设置固定结构，所述固定结构包括弹性压片，该弹性压片上设置有向背板表面凸起的突出部；制备灯条，包括在该灯条上设置有能与所述弹性压片上的突出部匹配的孔；将灯条上的孔与背板的固定结构的弹性压片上的突出部在灯条长度方向上对准后，将所述灯条与背板不断靠近，直至所述突出部与孔配合，从而将灯条与背板组装在一起。
本公开的技术方案提供了一种灯条与背板的有效固定方式，且结构简单、组装方便、便于重工、材料和人工成本低廉，克服了现有技术方案的灯条变形、材料浪费、组装和重工不便、人工成本较高等缺点。

具体实施方式
为使本领域的技术人员更好地理解本公开的解决方案，下面结合附图和具体实施方式对本公开的实施例所提供的背光模组及其组装方法、显示装置作进一步详细描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的前提下所获得的所有其他实施例，都属于本公开保护的范围。
现参照图4，其示出了根据本公开的实施例的背光模组10的示意图。该背光模组10例如可以是用于液晶显示器(LCD)的背光模组，且例如可以是直下式背光模组。如图中所示，该背光模组10包括背板1和灯条2。所述背板1上设置有固定结构3。优选地，所述固定结构3可以是多个固定结构3。例如，所述固定结构3可以包括多排固定结构3，每排固定结构3例如可以包括至少两个固定结构3，且每排固定结构3例如可以被配置为固定一个灯条2。尽管图4中仅示意性地示出了一个灯条2，但本领域的技术人员可知，背板1上可以固定有多个灯条2。
现参照图5A和图5B，其中，图5A示意性地示出了根据本公开的示例性实施例的背板1上的固定结构3的局部视图；图5B示意性地示出了根据本公开的示例性实施例的固定结构3 的局部剖面图。
可选地，该固定结构3可以通过在背板1上冲压而成。相应地，该固定结构3包括：与背板相连的根部31，以及一端与根部31相连、另一端为自由端的压片32。
可选地，所述压片32与背板1的表面大体平行。进一步可选地，所述压片32的下表面距背板1的上表面的高度h略大于或等于灯条2的厚度，以便于将灯条2固定于压片32之下。
因为背板1为钣金件材料，所以固定结构3的弹性压片32在上下方向上将具有一定的弹性，利用该弹性可以将灯条2固定到背板1上。
可选地，在所述压片32上设置有突出部4，该突出部4朝向背板1凸起。可选地，该突出部4是在压片32上冲压而成。该突出部4的顶端大小可以小于其根部大小。该突出部4例如可以为半球形(或部分半球形)、圆椎形、圆台形。该突出部也可以为其他形状，例如截面为椭圆形或其他封闭形状的椎形或台形。
所述压片32上设置的突出部4被配置为与在灯条2上设置的孔(如下所述)相配合，以对灯条2进行定位和限位。可选地，所述突出部4根部的直径(或大小)略大于所述孔的直径(或大小)，且所述突出部4端部的直径(或大小)略小于所述孔的直径(或大小)。
可以通过调整所述突出部4在弹性压片32上的位置来调整固定结构3与灯条2组装的紧密程度。例如，通常突出部4越靠近根部31，则固定结构3与灯条3的组装越紧密；突出部4越靠近压片32的自由端，则固定结构与灯条3的组装越宽松。换言之，所述突出部4在弹性压片32上的位置取决于所需要的灯条2与背板1组装的紧密程度，其中，所需要的灯条2与背板1组装得越紧密，则所述突出部4越靠近所述固定结构3的根部31。
现参照图6A和图6B，其中，图6A示意性地示出了根据本公开的示例性实施例的灯条2及灯条上与背板1上的所述固定结构3对应的结构；图6B示意性地示出了根据本公开的示例性实施例的灯条2上与所述固定结构3对应的结构的局部放大剖面图。如图中所示，在灯条2上与背板1上的上述固定结构3对应的位置(具体地，与所述固定结构3上的突出部4对应的位置)设置有孔5。所述孔5例如可以为通孔。所述孔5的直径可以略大于突出部4的端部的直径，但略小于突出部4的根部的直径。
这样，通过灯条2上的孔5与背板1的固定结构3上的突出部4之间的配合，就可以将 灯条2固定在背板1上。
可选地，所述孔5在面向突出部4的一侧具有倒角6，这样，可以更方便突出部4与孔5之间的组装配合。
现参照图7，其示意性地示出了根据本公开的示例性实施例的背板1的固定结构3与灯条2组装在一起的截面示意图。如图中所示，背板1的固定结构3上的突出部4部分地嵌入灯条2上的孔5中，从而实现了在X、Y、Z三个方向上同时对灯条2的固定和定位。
可选地，如图7中进一步示出的，固定结构3的压片的自由端略微抬起，从而更便利于灯条2与固定结构3的组装。
备选地，也可以考虑将所述突出部4或类似结构设置在灯条2上，而将所述孔5设置在背板1的固定结构3的压片上。
现参照图8A和图8B，其示出了将灯条2组装到背板1中的过程的示意图。如图中所示，可选地，在背板1上设置有定位挡墙8，该定位挡墙8固定于背板1上，且其位置使得当灯条2的侧边抵在挡墙上时，灯条2上的各个孔5与相应固定结构3上的突出部4在灯条长度方向上对齐。这样，只需要将灯条2沿其宽度方向(图中箭头所示方向)向固定结构3不断靠近，直至灯条2上的孔3与固定结构3上的突出部4相配合，就可实现灯条2与背板1的组装。
以上参照附图描述了根据本公开的实施例的背光模组，应指出的是，以上描述仅为示例，而不是对本公开的限制。在本公开的其他实施例中，所述背光模组可具有更多、更少或不同的部件，且各部件之间的包含、连接及功能等关系可以与所描述和图示的不同。例如，以上各示例性实施例中包含的特征通常可以以本领域技术人员可知的多种方式相互组合，从而形成新的实施例。
在本公开的另一个方面，还提供了一种显示装置，该显示装置包括显示面板，以及如上所述的背光模组。当然，如本领域的技术人员所知的，该显示装置还可能包括其他部件，如用于驱动显示面板的驱动电路等。由于这些其他部件均可以是现有部件，故在此不再赘述。
在本公开的另一个方面，还提供了一种背光模组的组装方法。该方法可用于组装上述根据本公开的各实施例的背光模组，为简明起见，在以下描述中省略了与以上描述重复的若干 细节，因此，可参照以上描述获得对该方法的更详细的了解。
现参照图9，其示出了根据本公开的实施例的背光模组的组装方法。如图中所示，该方法包括以下步骤：
在步骤901，制备背板，包括在该背板上设置固定结构，该固定结构包括弹性压片，该弹性压片上设置有向背板表面凸起的突出部；
在步骤902，制备灯条，包括在该灯条上设置能与所述弹性压片上的突出部匹配的孔；
在步骤903，将灯条上的孔与背板的固定结构的弹性压片上的突出部在灯条长度方向上对准后，将所述灯条与背板不断靠近，直至所述突出部与孔配合，从而将灯条与背板组装在一起。
可选地，所述固定结构包括至少一排固定结构，每排固定结构包括至少两个固定结构，且每排固定结构用于固定一个灯条。
可选地，所述制备背板包括通过冲压形成所述固定结构。
可选地，所述制备背板还包括在背板上设置挡墙，并且，将灯条上的孔与背板的固定结构的弹性压片上的突出部在灯条长度方向上对准是通过将灯条抵住所述挡墙实现的。
以上参照附图描述了根据本公开的实施例的光模组的组装方法，应指出的是，以上描述仅为示例，而不是对本公开的限制。在本公开的其他实施例中，所述组装方法可具有更多、更少或不同的步骤，且各步骤之间的顺序、包含及功能等关系可以与所描述和图示的不同。例如，通常多个步骤也可以被视为一个更大的步骤，一个步骤中包含的多个子步骤也可被视为多个单独的步骤。再例如，通常各步骤在以上描述和图示中的顺序并不构成对本公开的方法的限制，各步骤可以以本领域技术人员可知的任何顺序执行或同时执行。又例如，以上各示例性实施例中包含的特征通常可以以本领域技术人员可知的多种适当方式相互组合，从而形成新的实施例。
可以理解的是，本公开的以上各实施例仅仅是为了说明本公开的原理而采用的示例性实施例，本公开并不局限于此。对于本领域内的普通技术人员而言，在不脱离本公开的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为处于本公开的保护范围之内。本公开的保护范围仅由所附权利要求书的语言表述的含义及其等同含义所限定。
