如图1所示，本发明提供一种背光单元10，该背光单元10包括导光板110、灯条120、安装支架130、背板140、反射片150、光学膜160以及前框170，该背光单元10用于提供背光给显示面板190。
具体而言，灯条120设于导光板110侧边；安装支架130用于以侧插方式安装灯条120并用于夹持导光板110的侧边，安装支架130上设有隔离件131，隔离件131用于在允许光通过的前提下实现导光板110与灯条120的隔离，以防止导光板110碰撞灯条120进而损坏灯条120。
其中，安装支架130包括上支架板132、下支架板133以及中间支架134。下支架板133与上支架板132平行间隔设置；中间支架134将上支架板132和下支架板133垂直连接；其中，隔离件131自上支架板132和下支架板133相向延伸，隔离件131与上支架板132、中间支架134以及下支架板133构成灯条安装插槽135，为灯条120的安装构建出独立空间，该空间能够实现在不影响其他结构件的前提下，方便的进行灯条120的拆装，灯条安装插槽135的两端可以设置塑胶封口件，以进一步保护灯条120；隔离件131与上支架板132、下支架板133构成导光板夹持插槽136，隔离件131对于导光板110撞击具有较好的隔离保护作用。在优选实施例中，隔离件131的宽度可为0.4至2.5毫米。
请一并参阅图3a，在本发明的一优选实施例中，灯条120包括电路板121和设于电路板121上的LED灯122，电路板121的宽度在满足走线的前提下大于LED灯122的宽度，电路板121容置于灯条安装插槽135内，LED凸伸于隔离件131之间，以减小耦光距离，从而提高光效。
请一并参阅图3b，在本发明的另一优选实施例中，灯条120包括电路板121和设于电路板121上的LED灯122，电路板121的宽度和LED灯122的宽度相同或相近，电路板121的宽度满足最小走线即可，一起容置于灯条安装插槽135内，该结构简单便于安装。
请一并参阅图2、图3c以及图4b，在本发明的一优选实施例中，下支架板133上凸伸有凸柱137，上支架板132上设有沉孔138及穿设沉孔138与凸柱137连接的第一螺钉139，导光板110侧边对应于凸柱137设有插槽111，凸柱137和插槽111的数量不作限定，导光板110插入导光板夹持插槽136内时进一步由凸柱137和第一螺钉139限位，凸柱137和第一螺钉139可进一步辅助加强隔离件131的隔离强度，防止导光板110过大的活动。
请一并参阅图2、图3d和图4b，在本发明的另一优选实施例中，下支架板133上设有穿设于下支架板133的定位柱137′，上支架板132上设有沉孔138及穿设沉孔138与定位柱137′连接的第一螺钉139，导光板110侧边对应于定位柱137′设有插槽111，定位柱137′和插槽111的数量不作限定，导光板110插入导光板夹持插槽136内时进一步由定位柱137′和第一螺钉139限位，定位柱137和第一螺钉139可进一步辅助加强隔离件131的隔离强度，防止导光板110过大的活动。
在图3c和图3d所示的实施例中，凸柱137定位柱137′的设计主要用于应对超大尺寸（例如55寸及以上）的设计，此时导光板110的重量及膨胀空间需求较大，增加凸柱137定位柱137′可以有效地保证耦光结构的强度。
请继续参阅图1和图2，背板140通过第二螺钉171与下支架板133紧固，优选采用图中所示的台阶式配合方式；反射片150设于导光板110的背面和背板140之间；光学膜160设于导光板110上表面；前框170，呈L型前框170的一侧边171通过第三螺钉141与中间支架134紧固。当然，背板140与下支架板133及前框170与中间支架134也可采用卡扣或胶带方式进行固定。
本发明实施例中，上支架板132的前端进一步延伸有间隔片180，间隔片180压盖于光学膜160的侧边，用于间隔光学膜160和显示面板190，前框170的另一侧边172压盖显示面板190。
