Description

一种背光模组及显示装置 技术领域
本申请涉及显示技术领域，具体涉及一种背光模组及显示装置。
 背景技术
背光模组是液晶显示装置的重要组成部分，目前的背光模组的光源，主要是由发光二极管(LightEmittingDiode，简称LED)阵列组成。其中，次毫米发光二极管(miniLightEmittingDiode，简称MiniLED)作为一种直下式显示背光源，MiniLED背光技术相比于传统LED背光技术具有很多明显优势，MiniLED背光技术通过区域调光控制能够实现区域亮度调节，从而给客户带来更好的视觉体验。

本申请提供一种背光模组及显示装置，以下进行详细说明。需要说明的是，以下实施例的描述顺序不作为对本申请实施例优选顺序的限定。
请参阅图1，图1为本申请提供的背光模组100的第一结构的示意图，图2为本申请提供的背光模组100的第一结构的底板12的示意图；图3为图2的俯视图。本申请提供一种背光模组100，其包括背板10、LED灯板20和扩散板30。
其中，所述背板10具有凹腔11，所述背板10包括形成所述凹腔11的底部的底板12，所述底板12包括至少两个安装部121以及支撑部122，所述支撑部122直接连接在相邻所述安装部121之间。所述背板10还可包括与所述底板12相连接的侧板，所述侧板和所述底板12形成所述凹腔11。在底板12上设有安装部121和支撑部122，从而在生产背板10过程中即可以形成支撑部122，不需要在背光模组100组装过程中安装支撑部122。
所述LED灯板20设在所述安装部121的一侧面上并位于所述凹腔11内。所述底板12的安装部121用于安装所述LED灯板20，所述LED灯板20包括印制电路板21和设在所述印制电路板21上的Miniled22。
所述扩散板30设在所述LED灯板20的上方。
所述支撑部122向所述LED灯板20的光线出射方向凸出并支撑所述扩散板30。
本申请通过将背板10的底板12上设有用于支撑所述扩散板30的支撑部122，支撑部122不用和LED灯板20连接，相对于现有技术背光模组采用支撑架和LED灯板20连接的结构，本申请的支撑部122可以在背板10的底板12的制造过程中形成，因此在背光模组的组装过程中不需要安装支撑部122，从而可以减少背光模组的组装工序。
另外，现有技术的背光模组的LED灯板20都设置在背板10的凹腔11内，然后再通过支撑架将相邻的LED灯板20连接，由于需要在背板10的凹腔11内进行支撑架和LED灯板20的组装工序，因此组装难度较大。而本申请的支撑部122可以在背板10的底板12的制造过程中形成，在背光模组的组装过程不需要安装支撑部122，因此可以降低安装难度及成本。
在一些实施例中，所述安装部121和所述支撑部122一体化成型，具体地，所述安装部121和所述支撑部122可以通过冲压工艺一体化成型，也可以通过3D打印工艺一体化成型，也可以通过注塑工艺一体化成型，当然可以通过其他类型的一体化成型技术来生产所述安装部121和所述支撑部122。通过一体化成型可以减少所述背板10的底板12的生产工序。
在一些实施例中，所述支撑部122与所述扩散板30相接触的面为圆弧曲面1221。由于扩散板30为板状结构，如果支撑部122与所述扩散板30相接触的面是比较锋尖则会容易顶破扩散板30，因此将支撑部122与所述扩散板30相接触的面设为圆弧曲面1221，可以避免支撑部122顶破扩散板30。
进一步地，在一些实施例中，所述支撑部122向所述LED灯板20的光线出射方向凸出的部分的表面设有光反射层40。其中，所述光反射层40包括透明纳米涂层或漫反射涂层。透明纳米涂层具有较高的全反射率和漫反射率，因此具有较好的反射效果。而漫反射材料是由基料、漫反射材料、高导热材料、填料等组成，漫反射涂层的形成方式为：通过喷涂的方式或点胶的方式将漫反射材料喷在所述支撑部122伸出至所述凹腔11内的部分的表面上，从而均匀形成一层高漫反射白色涂层。所述漫反射涂层可以为水性丙烯酸涂层。
Miniled光源由多个LED灯板20拼接而成，LED灯板20拼接存在一拼接缝，拼接缝的位置即是与本申请支撑部122相对应的位置。本申请的支撑部122不是发光材料，当LED灯板20发光时，由于本申请的支撑部122的位置不发光，容易导致支撑部122区域的光线不均匀，影响显示面板的发光效果。因此，本申请在支撑部122向所述LED灯板20的光线出射方向凸出的部分的表面设有光反射层40，光反射层40可以将LED灯板20的光线反射至扩散板30，从而提高显示面板的发光均匀效果。
另外，在一些实施例中，所述支撑部122与所述LED灯板相背向的一侧设有容纳空腔1222。所述支撑部122是相对于所述安装部121向所述凹腔11内凸出的，因此通过设有容纳空腔1222可以降低所述支撑部122的厚度，从而可以提高支撑部122的散热效果。
进一步地，在一些实施例中，所述容纳空腔1222的腔壁上设有散热层50。通过散热层50可以提高支撑部122的散热效果。其中，所述散热层50包括石墨烯贴片、导热硅胶片和导热硅脂层中的任一种。
进一步地，在一些实施例中，所述支撑部122包括弯板，所述弯板的一端与相邻所述安装部121中的一个安装部相连接，所述弯板的另一端与相邻所述安装部121中的另一个安装部相连接。
也即是，所述底板12可以通过冲压工艺一体化成型或3D打印工艺一体化成型或注塑工艺一体化成型，从而使得底板12具有安装部121和弯板一体化成型的结构。其中，冲压工艺一体化成型过程如下：可以先根据底板12的结构生产相应的冲压模具，然后将形成底板12的板材放在冲压模具上，利用冲压机冲压板材，板材在冲压模具形成具有安装部121与弯板一体化成型结构的底板12。而3D打印工艺一体化成型具体过程如下：先通过计算机辅助设计软件生成底板12的3D打印数字模型，再将数字模型文件转换为立体光刻文件，将立体光刻文件导入到切片软件中进行处理，3D打印机根据立体光刻文件进行出具有安装部121与弯板一体化成型结构的底板12。
请参阅图4，图4为本申请提供的背光模组100的第二结构的示意图。再进一步地，在本申请其他实施例中，所述支撑部122向所述LED灯板20的光线出射方向凸出的部分的表面设有台阶1223，通过设有台阶1223可以增加所述支撑部122向所述LED灯板20的光线出射方向凸出的部分的表面积，从而可以提高散热面积以及反射面积。
具体地，所述支撑部122包括弯板，所述弯板的一端与相邻所述安装部121中的一个安装部相连接，所述弯板的另一端与相邻所述安装部121中的另一个安装部相连接。所述弯板为弧形板。所述弯板向所述LED灯板20的光线出射方向凸出的表面设有台阶1223，所述台阶1223的延伸方向与所述弯板的长度方向相平行。
其中，可以根据实际需要设置台阶的阶数，也即是，所述支撑部122向所述LED灯板20的光线出射方向凸出的部分的表面可以设有多阶台阶1223，从而增大散热面积以及反射面积，而提高支撑部的光反射能力，从而提高显示面板的发光均匀效果，另外也能提高支撑部的散热效果。
请参阅图5，图5为本申请提供的背光模组100的第三结构的示意图。另外，在本申请其他实施例中，所述容纳空腔1222内填充有散热材料60。通过散热材料60可以提高支撑部122的散热效果。其中，所述散热材料60包括导热硅胶。
在本申请其他实施例中，所述安装部121与所述支撑部122相连接的面上设有卡槽123或卡块124，所述支撑部122设有与所述卡槽123或所述卡块124相配合连接的卡块124或卡槽123。也即是在上述实施例中，所述安装部121与所述支撑部122并非是一体化成型的，而是通过配合连接而成，在实际生产过程中，先单独生产出安装部121和支撑部122，再将安装部121和支撑部122配合连接而形成底板。因此，上述实施例的支撑部122也可以在背板10的底板12的制造过程中形成，因此在背光模组的组装过程中不需要安装支撑部122，从而可以减少背光模组的组装工序并降低安装难度及成本。
请参阅图6，图6为本申请提供的背光模组100的第四结构的示意图。所述安装部121与所述支撑部122相连接的面上设有卡槽123，所述支撑部122设有与所述卡槽123相配合连接的卡块124。也即是，支撑部122位于对向两侧的连接面分别设有卡块124，位于支撑部122其中一连接面上的卡块124插入至相邻所述安装部121中的一安装部121的卡槽123内，位于支撑部122另一连接面上的卡块124插入至相邻所述安装部121中的另一安装部121的卡槽123内，从而使得支撑部122与相邻所述安装部121相连接。
请参阅图7，图7为本申请提供的背光模组100的第五结构的示意图。所述安装部121与所述支撑部122相连接的面上设有卡块124，所述支撑部122设有与所述卡块124相配合连接的卡槽123。也即是，支撑部122位于对向两侧的连接面分别设有卡槽123，相邻所述安装部121中的一安装部121的卡块124插入位于支撑部122其中一连接面上的卡槽123，相邻所述安装部121中的另一安装部121的卡块124插入位于支撑部122另一连接面上的卡槽123，从而使得支撑部122与相邻所述安装部121相连接。
在本申请其他实施例中，所述安装部121上设有第一连接部125，所述支撑部122设有第二连接部126，所述第一连接部125和所述第二连接部126粘合连接。也即是在上述实施例中，所述安装部121与所述支撑部122并非是一体化成型的，而是通过配合连接而成，在实际生产过程中，先单独生产出安装部121和支撑部122，再将安装部121和支撑部122通过胶水粘合连接而形成底板。因此，上述实施例的支撑部122也可以在背板10的底板12的制造过程中形成，因此在背光模组的组装过程中不需要安装支撑部122，从而可以减少背光模组的组装工序并降低安装难度及成本。
请参阅图8，图8为本申请提供的背光模组100的第六结构的示意图。所述安装部121上设有第一连接部125，所述支撑部122设有第二连接部126，所述第一连接部125和所述第二连接部126粘合连接。所述第一连接部125为设在所述安装部121侧面的第一对接面，所述第二连接部126为设在所述支撑部122侧面的第二对接面，第一对接面与第二对接面对接后通过胶水粘合连接，从而使得支撑部122与安装部121相连接。
请参阅图9，图9为本申请提供的背光模组100的第七结构的示意图。所述安装部121上设有第一连接部125，所述支撑部122设有第二连接部126，所述第一连接部125和所述第二连接部126粘合连接。所述第一连接部125为设在所述安装部121上的第一搭接边，所述第二连接部126为设在所述支撑部122上的第二搭接边，第一搭接边与第二搭接边搭接后通过胶水粘合连接，从而使得支撑部122与安装部121相连接。
请参阅图10，图10为本申请提供的背光模组100的第八结构的底板的示意图。图11为图10中的A-A剖视图。本实施例与图2所提供的背光模组100不同的是：所述底板12包括通孔123，所述通孔123由相邻所述安装部121合围而成，所述支撑部122设在所述通孔123上并与相邻所述安装部121直接连接。
所述支撑部122可以通过连接件与相邻所述安装部121直接连接，也可以通过粘合连接的方式与相邻所述安装部121直接连接，例如，所述安装部121上设有第一连接部，所述支撑部122设有第二连接部，所述第一连接部和所述第二连接部通过螺丝连接，或者，所述第一连接部和所述第二连接部粘合连接。
另外，所述支撑部122也可以与相邻所述安装部121一体化成型，所述安装部121和所述支撑部122可以通过3D打印工艺一体化成型，也可以通过注塑工艺一体化成型。
在一些实施例中，所述支撑部122包括柱形体，所述柱形体与所述LED灯板20相背向的一侧设有容纳空腔1222。此时所述支撑部可以为锥形壳结构，所述安装部121和所述支撑部122也可以通过冲压工艺一体化成型，例如所述底板12包括一块平板，在所述平板与所述通孔123相对应的位置进行冲压，使得所述平板上述位置被冲压凸出而形成所述支撑部122，而所述平板上位于所述支撑部122两侧的部分为所述安装部121。
相应地，本申请实施例还提供一种显示装置，所述显示装置包括：显示面板和如上所述的背光模组100，所述显示面板与所述背光模组100相对设置。
与现有技术相比，本申请实施例提供的显示装置的有益效果与上述技术方案提供的背光模组的有益效果相同，在此不做赘述。
