多个光源11间隔设置在底板14上。可选的，光源11为LED灯，但并不限于此。
透镜12设置在光源11的出光面上。扩散板13设置在透镜12上。
其中，透镜12包括透镜本体121和支撑部122。透镜本体121设置于光源11的出光面上。支撑部122设置在透镜本体121和扩散板13之间。透镜本体121用于将光源11的光线进行扩散处理。支撑部122用于支撑扩散板13。
本第一实施例的背光模组100将透镜本体121和支撑部122进行结合形成透镜12，并将支撑部122设置在透镜本体121和扩散板13之间，且用于支撑扩散板13。这样的设置，缩短了支撑部122的高度，进而提高了支撑部122的支撑性能。
具体的，相较于现有技术，本第一实施例的支撑部122减少了部分高度。该部分高度为透镜本体121的出光面到底板14上表面的距离。由于支撑部122高度的缩减，进而使得支撑部不易发生形变。
本第一实施例的背光模组100还包括光学膜片（图中未标示），光学膜片设置在扩散板13上。
其中，透镜本体121和支撑部122一体成型。由于二者通过模具一次成型，在工艺上，节省了工艺步骤；在性能上，提高了二者连接的稳定性。当然，二者也可以是分体固定连接。
在本第一实施例中，支撑部122至少设置有一个。由于支撑部122用于支撑扩散板13，因此支撑部122会受到扩散板13的压力。而如果当只有一个支撑部122时，在扩散板13的压力下，透镜12由于受力不均而导致透镜12发生倾斜，进而导致透镜12偏离光源11的出光面。为了克服上述的缺陷，本第一实施例的支撑部122具有至少两个。至少两个支撑部122均匀设置在透镜本体121的出光面上。
在本第一实施例中，透镜本体121具有一出光面。该出光面包括第一出光面12a和第二出光面12b。第二出光12b面围设在第一出光面12a的外周。第一出光面12a为凹面。支撑部122设置在第二出光面12b上。
具体的，第一出光面12a位于透镜本体121的出光面的中间区域，且第一出光面12a的出光量比第二出光面12b的出光量大，因此将支撑部122设置在第二出光面12b上可提高背光的出光效果，即避免透镜的支撑部122所对应的出光区域的亮度过高。
另外，支撑部122的外表面为粗糙面。这样的设置，使得支撑部122的表面具有光散射性能，即光学照射到支撑部122的表面时，会发生散射效果，进而使得照射至支撑部122的光线被分散，使得背光的出光更为均匀，从而提高了背光出光效果。
可选的，支撑部122为锥形结构，但并不限于此。由于支撑部122的顶部相较于底部更靠近扩散板13，因此支撑部122的顶部接受的光线量对背光出光的影响要大于其底部接受的光线量对背光出光的影响。因此支撑部122为锥形结构使得光线照射支撑部122顶部的光线量变小，进而减小支撑部122对背光出光的影响，即提高了背光出光的效果。
请参照图3，图3为本申请第二实施例的背光模组的透镜的结构示意图。透镜22包括透镜本体221和支撑部222。本第二实施例与第一实施例的不同之处在于：
透镜本体221具有一出光面22a。出光面22a为一凹面。支撑部222设置在出光面22a的边缘。
本第二实施例的其他结构具体请参照第一实施例的内容，在此不再赘述。
请参照图4，图4为本申请实施例的显示装置的结构示意图。本申请实施例的显示装置1000包括显示面板200和背光模组100。
本实施例的显示装置1000的背光模组100的具体结构的内容请参照本申请上述第一实施例的背光模组和第二实施例的背光模组，在此不在赘述。
相较于现有技术的背光模组，本申请的背光模组及显示装置将透镜本体和支撑部进行结合形成透镜，并将支撑部设置在透镜本体和扩散板之间，且用于支撑扩散板；这样的设置，缩短了支撑部的高度，进而提高了支撑部的支撑性能；解决了现有的背光模组的支撑结构容易形变的技术问题。
以上所述，对于本领域的普通技术人员来说，可以根据本申请的技术方案和技术构思作出其他各种相应的改变和变形，而所有这些改变和变形都应属于本申请后附的权利要求的保护范围。
