【具体实施方式】
参阅图1，图1是本发明第一实施例的背光模组的结构示意图。本发明第一实施例的背光模组包括导光板110、反射片120、背框130、支撑体140以及光源170。
反射片120设置于导光板110下方，背框130用于承载导光板110和反射片120。背板130包括承载部131、弯折部132以及凹陷部133。承载部131承载导光板110和反射片120，在导光板110靠近光源170的入光侧的边缘处弯折部132远离导光板110延伸，并在延伸预定距离后平行承载部131延伸，形成凹陷部133。由此，导光板110靠近光源170的入光侧的边缘处与背框130之间具有间隙。支撑体140设置于间隙处，用于支撑导光板110及反射片120。在本实施例中，支撑体140的顶端与承载部131的承载面位于同一平面。
在本实施例中，支撑体140为支撑柱140。背框130的凹陷部133上设置有通孔134，支撑柱140的第一端从通孔134中穿过并抵靠反射片120，第二端固定于背框130上。参阅图1可以得知，支撑柱140的主体的截面大于通孔134的截面。支撑柱140的第二端为弹性部141，弹性部141卡置在背框130的外壁，以使支撑柱140与背框130弹性卡合。安装支撑柱140时，将弹性部141由背框130的内部通过通孔134向外挤压，使弹性部141发生弹性形变，穿过通孔134后还原，使支撑柱140与背框130弹性卡合。其中，弹性部141的顶端为弹性卡钩。在其他实施例中，弹性部141也可为蘑菇头卡扣。应理解，支撑柱140的第二端也可通过螺丝或连接销固定在背框130上。并且，支撑柱140的材质可以是塑胶、橡胶、硅胶以及金属等，具有一定的弹性，且不易损坏。
参阅图2，图2是本发明第二实施例的背光模组的结构示意图。本发明第二实施例的背光模组包括导光板210、反射片220、背框230以及支撑体240。
本实施例与第一实施例所不同的是，在本实施例中，支撑体240为支撑块240。支撑块240的上端抵靠反射片220，下端抵靠背框230的内壁。支撑块240的上端具有一凹槽241，凹槽241中具有贯穿支撑块240上端和下端的第一螺钉孔242。背框230设有与第一螺钉孔242对应的第二螺钉孔234。背光模组进一步包括螺钉250，螺钉250穿设第一螺钉孔242以及第二螺钉孔234，以将支撑块240固定于背框230上。其中，螺钉250的钉帽251设置于凹槽241中，且不抵靠反射片。并且，螺钉250的长度要大于第一螺钉孔242的长度，且不大于第一螺钉孔242与第二螺钉孔234的长度之和。在其他实施例中，可使用铆钉等穿设于第一螺钉孔242以及第二螺钉孔234中进行固定，也可使用一弹性柱弹性卡合于第一螺钉孔242以及第二螺钉孔234中。支撑块240的材质可以是塑料、塑胶、橡胶、硅胶以及金属等。
同样的，背板230包括承载部231、弯折部232以及凹陷部233，并且支撑块240的顶面与承载部231的承载面位于同一平面。
参阅图3，图3是本发明第三实施例的背光模组的支撑件的立体视图。本实施例与第二实施例的主要区别在于，支撑块340上除了具有凹槽341以及第一螺钉孔342外，还包括弹性突起343。
图4是本发明第三实施例的背光模组的部分立体示意图，图5是本发明第三实施例的背光模组的侧视图。请参阅图4与图5，本发明的背光模组进一步包括设置于导光板310上方的光学膜片360。弹性突起343从凹槽341的表面朝导光板310的方向延伸。导光板310和反射片（未图示）对应弹性突起343处设置有凹槽341，光学膜片360对应弹性突起343处设置有开口361，弹性突起343穿过凹槽341，且外力压缩后弹性突起343插入光学膜片360上的开口361，弹性结构撤去外力后弹回，以使其顶端穿出开口361并卡合于光学膜片360表面，以此对光学膜片360进行固定，使之可以悬挂，，防止光学膜片360在外力作用时跳出。
其中，弹性突起343的顶端为弹性卡钩，在其他实施例中，弹性突起343的顶端也可为蘑菇头卡扣。如前所述，支撑块340的材质可以是塑胶、橡胶、硅胶以及金属等，具有一定的弹性，且不易损坏。
在本实施例的其他变形中，可以省略螺丝，仅将支撑块固定在光学膜片及导光板上，背框也不需进行开口。
本发明进一步公开了一种显示装置，其包括显示面板以及背光模组，背光模组用于为显示面板提供背光源。其中，背光模组为上述各实施例所述的背光模组。
区别于现有技术，本发明的显示装置及其背光模组通过上述方式，在导光板靠近光源的入光侧的边缘处与背框之间的间隙处设置一支撑体，能够配合背框一起承载导光板及反射片等，能够防止导光板在入光侧因自重出现弯曲或弯折，稳定背光模组的出光效率，避免背光模组辉度不足的缺陷。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
