具体实施方式
以下，将参照附图来详细描述本发明的实施例。然而，可以以许多不同的形式来实施本发明，并且本发明不应该被解释为限制于这里阐述的具体实施例。相反，提供这些实施例是为了解释本发明的原理及其实际应用，从而使本领域的其他技术人员能够理解本发明的各种实施例和适合于特定预期应用的各种修改。在附图中，相同的标号将始终被用于表示相同的元件。
参照图1、图2及图3，本实施例提供的液晶显示器包括背光模组1和显示模组2。背光模组1用于为显示模组2提供光源14，显示模组2用于对图像进行显示。具体的，背光模组1包括背板11、导光板12、光学膜片组13及光源14。背板11包括底板11a，导光板12、光学膜片组13从下而上依次设于底板11a上，光源14包括多个LED灯14a，多个LED灯14a位于底板11a上并与导光板12的入光面相对设置，底板11a朝向导光板12的一面涂覆有反射材料。
本实施例中的背光模组1为侧入式，导光板12的侧面即为其入光面，LED灯14a发射的光束从入光面进入导光板12的内部并在导光板12中进行多次反射后从导光板12的顶部均匀出射，其中，入射到导光板12的底部的光束被背板11表面的反射材料反射进导光板12中。因此，本实施例中的背光模组1省去了传统背光模组中的反射片，简化了结构、减轻了重量、缩短了组装时间。
背板11还包括由底板11a向上弯折延伸出的侧板11b，LED灯14a位于侧板11b与导光板12之间，侧板11b环绕导光板12和光源14设置，侧板11b远 离导光板12的入光面的一侧呈开口状。
背板11还包括由侧板11b朝向光学膜片组13弯折延伸出的顶板11c，顶板11c延伸至光学膜片组13的边缘并与光学膜片组13的上表面贴合。顶板11c、侧板11b、底板11a、导光板12及光学膜片组13围合成一个容置空间，光源14收容于该容置空间中。本实施例中的背板11的材质为金属，其与显示模组2的电路连接，可以对显示模组2上的静电进行释放，从而防止静电对显示模组2的电路造成损坏。
本实施例中的侧板11b与顶板11c朝向导光板12的一面涂覆有遮光材料即在侧板11b与顶板11c的内侧涂覆有遮光材料。通过在侧板11b的内侧涂覆遮光材料使得侧板11b具有传统背光模组中的胶框的作用，通过在顶板11c的内侧涂覆遮光材料使得顶板11c具有传统背光模组中的遮光胶层的作用，因此，本实施例中的背光模组1能够省掉传统背光模组中的胶框和遮光胶条15，从而可选地简化了结构、减轻了重量。
本实施例中的光源14还包括基板14b，多个LED灯14a分别设于基板14b上并与其电连接。基板14b为FPC，其设于顶板11c与多个LED灯14a之间，优选的，基板14b完全覆盖多个LED灯14a并延伸至导光板12的边缘并与导光板12的上表面贴合，通过将基板14b延伸至导光板12的表面一方面可以提升LED灯14a的散热效果，另一方面可以起到遮光的作用。
参照图4、图5，为了提升整个背光模组1的强度，背光模组1还包括设于底板11a上的胶条15，胶条15与光源14分别位于导光板12相对的两侧,即胶条15位于侧板11b呈开口状的一侧。胶条15包括垂直于底板11a的垂直部15a及由垂直部15a朝向光学膜片组13弯折延伸出的水平部15b，水平部15b延伸至光学膜片组13的边缘并与光学膜片组13的上表面贴合。
胶条15由不透光的材料制成，其用于支撑光学膜片组13，同时用于将光学膜片组13和背板11固定在一起。其中，为了防止漏光，在垂直部15a的外侧及底板11a的底部分别粘贴有遮光胶带16，这样，从垂直部15a和底板11a之间的缝隙处出射的光线可以被遮光胶带16遮挡。
为了便于安装，侧板11b呈开口状的一端设有固定孔100，垂直部15a上设 有与固定孔100对应的凸块101，优选的，侧板11b上设有两个固定孔100，两个固定孔100分别位于导光板12的两侧，对应的，凸块101的数量也为两个，两个凸块101位于垂直部15a的两侧。由于胶条15具有一定的弹性，在组装过程中，通过将凸块101卡合于固定孔100中便可以将胶条15和侧板11b进行固定。
参照图6，导光板12的入光面上间隔设置有多个挡板12a，多个挡板12a与侧板11b围合形成多个放置槽，多个LED灯14a一一对应的收容于多个放置槽中。优选地，本实施例中的多个挡板12a等间隔的设置于入光面上。
本实施例还提供了一种如上所述的背光模组1的组装方法，所述组装方法包括：
步骤S1、将光源14、光学膜片组13分别贴附于导光板12上，形成第一组件；
步骤S2、将第一组件从背板11呈开口状的一侧插入背板11中，形成背光模组1。
具体地，将第一组件从背板11呈开口状的一侧插入背板11中后，步骤S2还包括将胶条15从背板11呈开口状的一侧插入，使得垂直部15a上的凸块101卡合于侧板11b上的固定孔100中，此时，水平部15b与光学膜片组13的上表面贴合、垂直部15a垂直于底板11a并与底板11a的表面贴合。最后，在垂直部15a的外侧和底板11a的底部粘贴遮光胶带16，得到背光模组1。
本实施例中的显示模组2包括从下而上依次层叠设置的下偏光片21、显示组件22及上偏光片23，上偏光片23和下偏光片21将显示组件22夹设于其中。显示组件22的一端与顶板11c的表面贴合、另一端与胶条15的表面贴合。上偏光片23和下偏光片21用于将显示组件22的出射光和入射光转换为具有预定偏振方向的线偏振光，其中，上偏光片23和下偏光片21的偏振方向相互垂直。
以上所述仅是本申请的具体实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
