Description

一种背光模组与显示装置 技术领域
本发明涉及液晶显示技术领域，尤其涉及一种背光模组与显示装置。
背景技术
随着液晶显示装置在各个领域的广泛应用，人们对于液晶显示装置的薄型化和窄边框化提出了更高的要求，要求液晶显示模块的厚度尽可能薄、边框尽可能窄。然而，为了对液晶显示装置内的各种零部件进行固定，通常需要在各个零部件上预留用于设计定位结构的空间，难以避免地增加液晶显示装置整体的厚度和宽度。因此，如何对显示装置进行固定的同时不影响其厚度和边框宽度非常重要。
发明内容
鉴于现有技术存在的不足，本发明提供了一种固定可靠的同时有利于实现薄型化和窄边框化的背光模组与显示装置。
为了实现上述的目的，本发明采用了如下的技术方案：
一种背光模组，包括背板、依次堆叠于所述背板上的反射片、导光板和光学膜片组以及设于背光模组边缘的多个连接件，所述连接件包括间隔块和连接在所述间隔块上表面的上连接部，所述间隔块被夹设于所述背板和所述反射片之间，所述上连接部同时与所述反射片、所述导光板和所述光学膜片组相对固定。
其中，所述间隔块与所述背板相对固定。
其中，所述连接件还包括连接在所述间隔块下表面的下连接部，所述背板周缘开设有第一通孔，所述下连接部穿设在所述第一通孔内。
其中，所述反射片、所述导光板和所述光学膜片组的周缘分别凸设有第一凸耳、第二凸耳和第三凸耳，所述上连接部同时穿设在所述第一凸耳、所述第二凸耳和所述第三凸耳上。
其中，所述第一凸耳、所述第二凸耳和所述第三凸耳上分别开设有对应上连接部的第二通孔、缺口和第三通孔。
其中，所述上连接部为凸柱。
其中，所述间隔块粘贴在所述反射片上。
或者，所述上连接部包括自所述间隔块依次延伸的第一插接部、第二插接部和自所述第一插接部朝所述间隔块凸起的挂钩部，所述第一插接部和所述第二插接部分别插设于所述导光板和所述光学膜片组上，所述挂钩部勾设在所述反射片上。
其中，所述第一插接部与所述间隔块间形成供所述反射片插入的避位间隙，所述间隔块包括倾斜的引导面，用于引导所述反射片插入所述避位间隙。
本发明的另一目的在于提供一种显示装置，包括前框、显示面板和上述的背光模组，所述显示面板设于所述背光模组上，所述前框罩设于所述显示面板外表面。
本发明通过在背光模组的边缘设置多个连接件，利用连接件将反射片、导光板和光学膜片组同时连接，同时通过连接件上的间隔块还可将反射片、导光板和光学膜片组与背板间隔开，有利于减少反射片、导光板、光学膜片组的定位机构占用的空间，有利于显示装置的超薄、超窄边框设计，提高了产品的组装效率。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
实施例1
参阅图1，本发明的显示装置包括胶框100、前框200、显示面板300、背板10、反射片20、导光板30和光学膜片组40，胶框100和胶框100内的背板10、反射片20、导光板30和光学膜片组40构成背光模组的一部分，显示面板300贴合在胶框100上，前框200罩设于显示面板300外表面起保护和限位作用。
结合图2和图3所示，背光模组中，背板10上依次堆叠有反射片20、导光板30和光学膜片组40，多个连接件50间隔地固定在背光模组的边缘，连接件50包括间隔块51和连接在间隔块51上表面的上连接部52、连接在间隔块51下表面的下连接部53，间隔块51被夹设于背板10和反射片20之间，背板10周缘开设有第一通孔11，下连接部53穿设在第一通孔11内，上连接部52同时与反射片20、导光板30和光学膜片组40相对固定。
通过这样的设置，反射片20、导光板30和光学膜片组40通过连接件50的上半部分同时连接，连接件50的下半部分与背板10相对固定，间隔块51被夹持于背板10和反射片20之间，起到间隔反射片20与背板10的作用，反射片20与背板10之间的间隙内还可设置散热片对背光源进行散热，只需要在背光模组的边缘设置一圈此连接件50即可实现背光模块的固定，有利于减少反射片、导光板、光学膜片组的定位机构占用的空间，有利于显示装置的超薄、超窄边框设计，可以提高产品的组装效率。
具体地，本实施例的上连接部52、下连接部53均为凸柱，反射片20、导光板30和光学膜片组40的周缘分别凸设有第一凸耳21、第二凸耳31和第三凸耳41，第一凸耳21、第二凸耳31和第三凸耳41上分别开设有对应上连接部52的第二通孔210、缺口310和第三通孔410，上连接部52同时穿设在第二通孔210、缺口310和第三通孔410上。
第一凸耳21与间隔块51之间设有双面胶，在组装时可以将间隔块51粘贴在反射片20上后进行下一步组装操作。
具体在组装时，首先将连接件50的间隔块51粘贴在反射片20并使上连接部52插入反射片20的第二通孔210内，将连接件50的下连接部53插入背板 10的第一通孔11内，然后依次组装导光板30和光学膜片组40，使导光板30的缺口310和光学膜片组40的第三通孔410分别套设在上连接部52上，最后组装胶框100、显示面板300和前框200即可，背板10可作为组装平台，大大提高了组装效率。
由于背光模组上用于穿设连接件50的第一凸耳21、第二凸耳31和第三凸耳41都是设置在相应零部件的周缘，每个连接件50同时穿设在相应的凸耳中，并不会大幅增加显示装置的边框，同时，反射片20、导光板30和光学膜片组40均紧贴在一起，背板10与反射片20之间的间隙可用于安装散热片，此间隙的大小可通过调节间隔块51的厚度进行设置，使得显示装置结构紧凑，其厚度得以尽可能薄，有利于显示装置的薄型化设计。
实施例2
如图4～图6所示，与实施例1不同的是，本实施例的连接件50的结构不同。本实施例的上连接部52包括自间隔块51依次延伸的第一插接部521、第二插接部522和自第一插接部521朝间隔块51凸起的挂钩部523，第一插接部521和第二插接部522分别插设于导光板30和光学膜片组40上，挂钩部523勾设在反射片20上。
结合图7，在第一插接部521与间隔块51间形成供反射片20插入的避位间隙，间隔块51包括倾斜的引导面51S，具体是在间隔块51靠近挂钩部523的一侧进行倒角处理，可用于引导反射片20插入避位间隙，减小间隔块51与反射片20的第一凸耳21的干涉。本实施例的第一插接部521为方形的中空筒体结构，第二插接部522仅为该中空筒体的一个侧壁，光学膜片组40上与第二插接部522配合的第三凸耳41、第三通孔410可以做得更小，更加有利于窄边框化。
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。
