交叉引用
[根据细则26改正21.11.2016]　
本申请引用于2015年11月20日提交的专利名称为“显示器背光模组”的第2015209370184号中国专利申请，其通过引用被全部并入本申请。
技术领域
本申请属于液晶显示器技术领域，具体地，涉及一种显示器背光模组。
背景技术
液晶显示器现已成为主流的显示器设备，其在电脑、电视、手机等电子产品的应用十分广泛。由于液晶本身并不发光，为了使液晶显示器正常显示映像，在液晶屏中设置背光模组是必要的。背光模组能够为液晶提供充足、均匀的光线。
在现有的液晶显示器中，本领域技术人员通常使用的是边光式背光源，这种背光源是由线形或点状发光体设置在导光板侧面形成的，导光板可以将从侧面射入的光线引导至正面射出。根据实际的性能要求，可以做成双边式或三边式背光源。在实现本申请过程中，发明人发现现有技术中至少存在如下问题：在这种背光技术中，发光体通常需要与导光板的侧面中心相对，这样才能够保证良好的光学效果，不会造成漏光、光线不足等问题。如果发光体的安装位置偏离了与导光板正对的位置，则容易出现漏光现象。图1示出了一种边光式背光源，其中包括发光体01，由于发光体01的安装位置向上偏移，没有对准导光板，所以使得一部分光线直接从框架结构的缝隙处射出，无法进入导光板。这样，会出现漏光现象并且降低光线的利用率，造成显示屏的背光亮度降低、不均匀等问题。
所以，有必要对边光式背光源的结构进行改进，避免光线漏出，或 者防止发光体的安装位置偏离，从而保证显示器具有充足、稳定的背光，不会出现亮度减弱或明暗不均的问题。
发明内容

可选地，所述框架可以包括散热板，所述散热板形成所述框架的底部和密封框。
可选地，所述框架可以包括顶框，所述顶框覆于所述光学组件上方。所述顶框可以形成所述密封框。
可选地，所述顶框上可以设置有泡棉，所述泡棉与所述光学组件的上表面相对。
可选地，所述光源为LED灯条，所述LED灯条包括灯板和灯珠，所述腔室的高度与所述灯板的宽度相匹配，所述灯珠与所述导光板的侧面相对。
可选地，所述光学组件包括反射膜和光学膜材，所述反射膜设置在所述导光板的下表面上，所述光学膜材设置在所述导光板的上表面，所述反射膜与所述框架的底部接触。可选地，所述光学膜材完全位于所述腔室之外。
本申请实施例的一个技术效果在于，所述显示器背光模组能够将光源射出的光线封在腔室中，防止漏光现象，避免光线的浪费。
通过以下参照附图对本申请的示例性实施例的详细描述，本申请的其它特征及其优点将会变得清楚。
附图说明

图4是本申请具体实施例中图3的放大图。
具体实施方式
现在将参照附图来详细描述本申请的各种示例性实施例。应注意到：除非另外具体说明，否则在这些实施例中阐述的部件和步骤的相对布置、数字表达式和数值不限制本申请的范围。
以下对至少一个示例性实施例的描述实际上仅仅是说明性的，决不作为对本申请及其应用或使用的任何限制。
对于相关领域普通技术人员已知的技术和设备可能不作详细讨论，但在适当情况下，所述技术和设备应当被视为说明书的一部分。
在这里示出和讨论的所有例子中，任何具体值应被解释为仅仅是示例性的，而不是作为限制。因此，示例性实施例的其它例子可以具有不同的值。
应注意到：相似的标号和字母在下面的附图中表示类似项，因此，一旦某一项在一个附图中被定义，则在随后的附图中不需要对其进行进一步讨论。
第一实施例
本申请第一实施例提供了一种显示器背光模组，其中包括框架、光学组件和光源。如图2所示，所述框架具有底部11和密封框12，所述密封框12位于所述底部11的边缘处并从所述底部11向上延伸，所述光学组件至少包括导光板21。所述框架用于承载所述光学组件和光源4，所述光学组件设置在所述框架的底部11上，所述光学组件靠近所述底部11的边缘。所述密封框12与所述光学组件的边缘连接，从而在所述框架与所述光学组件之间形成封闭的腔室3。所述光源4设置在所述腔室3中，光源4朝向所述导光板21的侧面。由于所述腔室3是密封结构，所以光源4射出的光线不会从所述腔室3中漏出。如果光源4在装入腔室3时偏离了与所述导光板21对正的位置，部分从光源4中射出的光线不能直接射入导光板21，但是所述腔室3是封闭的，光线经过反射也可以射入所述导光板21中。本申请通过在框架与光学组件之间设置封闭的空腔防止了漏光现象，而且，即使光源的装配位置出现偏移，也不会严重影响光线的入射量。
第二实施例
本申请进一步提供了第二实施例。如图2所示，所述框架的底部11呈平面状，所述密封框12从底部11向上延伸再与光学组件围成一个封闭的腔室3。所述光源4贴覆设置在密封框12的侧壁上并与导光板21相对，光源4射出的光线通常能够直接从导光板21的侧面射入导光板21中。导光板21改变光线的方向，光线从其上方射出。在图2示出的实施例中，所述密封框12从所述导光板21的上方向下延伸一端距离并与导光板21的上表面接触，这样，所述腔室3的空间更大，便于设置光源4。在本申请的其它实施例中，所述密封框12也可以直接延伸到导光板21的侧面，也可以与导光板21组合成密封的腔室3，在这种情况下，腔室3的空间较小，密封框12占用的空间也更小。本领域技术人员可以根据产品的具体情况和性能要求，选择密封框的结构形状。本显示器背光面模组的另一 个技术效果在于，由于形成有封闭的腔室3，腔室3能够对光源4的位置进行限制，图2示出的是光源4正对导光板21的情况，图3示出的是光源4相对于导光板21向上偏移的情况，可见光源4不会严重偏离正对导光板21的位置，所以减少了光线的浪费。另外，本申请的附图示出的是所述显示器背光模组的局部剖视图，图中只示出了光学组件的一侧，本申请并不限制该背光模组在几个侧边上设置有腔室和光源，本领域技术人员可以根据实际情况选择。
可选地，为了进一步增加光线的利用率，降低光线损失，所述密封框12的内表面上可以涂覆有反光涂层。如果密封框12内没有反光涂层，一部分没有直接射入导光板21的光线会被密封框12吸收，只有剩下的部分光线会经过密封框12的反射进入导光板21。如果密封框12的内表面涂覆有反光涂层，如图4所示，则会大大增强密封框12的反射效果，光线最终会经过密封框12的反射进入导光板21。
可选地，如图2-4所示，在该实施例中，所述框架包括散热板5，所述散热板5构成了所述框架的底部11和密封框12。散热板5能够为显示器背光模组提供良好的散热效果。可选地，所述框架还可以包括顶框13，所述顶框13覆于所述光学组件的上方，以对光学组件起到保护作用。在图2-4所示的实施例中，所述顶框13是固定在散热板5上的，在本申请的其它实施例中，当所述框架还包括其它结构时，所述顶框13还可以固定在其它结构上。可选地，所述顶框13可以代替散热板构成所述密封框12。在这种情况下，所述框架的底部11由散热板构成，所述顶框13设置在所述散热板上，顶框13的一部分与所述导光板21连接，形成密封的腔室3。所述顶框13的另一部分可以继续想光学组件的中心延伸一段，以起到保护作用。
可选地，所述顶框13上可以设置有泡棉131，以对光学组件的上表面进行保护，所述光学组件的上表面往往设置有光学膜材23，光学膜材23对冲击、压力等外界接触十分敏感，性能不稳定。泡棉131可以减轻光学膜材23在装配、搬运、使用时受到的压力，提高光学组件的性能稳 定性。
可选地，如图2-4所示，本申请所述的光源4可以是LED灯条，所述灯条包括灯板41和灯珠42。所述灯板41上设置有电路并对灯珠42起到承载作用，所述灯珠42为发光体。所述腔室3的高度可以与所述灯板41的宽度相匹配，使灯板41穿入腔室3时位置基本固定，起到对灯珠42与导光板21的定位作用，所述灯珠42与所述导光板21的侧面相对。
另外，如图2、3所示，所述光学组件还可以包括反射膜22和光学膜材23，所述反射膜22位于所述导光板21的下表面，其直接设置在所述框架的底部11上。所述光学膜材23设置在所述导光板21的上表面。可选地，所述密封框12不与所述光学膜材23接触，而是直接与导光板21接触围成腔室3，原因在于，一方面光学膜材23对压力十分敏感，密封框12与光学膜材23接触有可能对其光学性能造成影响；另一方面，如果所述光源4向上偏移，则光线有可能直接照射到光学膜材23上，进而造成光线的浪费。所以可选地，所述光学膜材23可以完全位于所述腔室3之外，密封框12不与光学膜材23接触，避免上述情况。例如，如图2-4所示，所述光学膜材23的大小可以略小于所述导光板21，使导光板21的边缘处未覆盖光学膜材23，供密封框12连接。
虽然已经通过示例对本申请的一些特定实施例进行了详细说明，但是本领域的技术人员应该理解，以上示例仅是为了进行说明，而不是为了限制本申请的范围。本领域的技术人员应该理解，可在不脱离本申请的范围和精神的情况下，对以上实施例进行修改。本申请的范围由所附权利要求来限定。
