Description

背板及显示装置 技术领域
本申请涉及显示技术领域，尤其涉及一种背板及显示装置。
 背景技术
近些年来，显示器不但越来越高清，也越来越超薄大视角，显示器前框的四边越来越窄，四周窄边框，乃至无边框的极致需求更是在显示行业越来越火爆。然而，对于窄边框或无边框的模组来说，如何固定膜片，例如光学膜片是个大问题。
在现在技术中，通常利用中框来固定膜片。详细来讲，在膜片的边缘处形成挂耳，而在中框的顶面边框处形成铆柱，利用膜片的挂耳与中框的铆柱配合实现对膜片的定位，但对于窄边框或四周无边框的显示器来说，这种结构设计显然不适用，因为边框的距离越来越窄，在边框上根本没有多余的空间设置铆柱。
因此，亟需提供一种新的结构以固定膜片，以解决上述问题。

如图1所示，所述背板1还具有一直线型的连接槽16，所述连接槽16形成于所述背板主体10的顶面，并且与所述埋线槽12相连通。在本实施例中，所述膜片2的挂耳20的至少一部分能够伸入所述连接槽16内，以减少所述膜片2与所述背板1之间的间隙。
如图1所示，所述膜片2具有至少一挂耳20。在本实施例中，所述膜片2具有四个挂耳20，并且分布于所述膜片2的四角处，但图中仅表现出所述膜片2的其中一个角及一个挂耳20。在每一挂耳20上均开设有一挂耳孔22，为了安装方便，所述挂耳孔22应比所述固定件3的直径稍大。所述挂耳孔22为圆形通孔，亦可以是椭圆形、方形、三角形和其他形状。
如图2所示，所述固定件3与所述挂耳20连接并固定。在本实施例中，所述固定件3与所述挂耳20为可拆卸连接，一般情况，可以通过粘接剂、锁扣、粘扣、卡扣、绳结等方式固定。所述固定件3与所述埋线槽12配合。所述固定件3为弹性圈，其材料可以是橡胶、金属和其他具有一定延展性的物质。所述弹性圈与所述埋线槽12及所述连接槽16配合，一般情况，是利用所述弹性圈的弹性，将所述弹性圈卡入所述埋线槽12及所述连接槽16内，如果用粘接剂将所述固定件3封装在所述埋线槽12中也是可以的。所述固定件3为弹性丝，所述弹性丝环绕所述埋线槽12完成固定后，自锁。所述弹性丝的材料可以是橡胶、金属和其他具有一定延展性的物质。
如图1所示，所述埋线槽12的深度应该大于所述固定件3的直径，保证所述固定件3安装后，不会凸出，避免影响后面的装配和美观。此外，在其它实施例中，所述埋线槽12亦可只开设为直线型的埋线槽，通过直接将所述固定件3通过粘接剂粘合在所述埋线槽12内，能够提供固定作用即可。所述埋线槽12的截面为 T形槽，T形槽有效避免所述固定件3在安装后脱离。同时所述埋线槽12不限于T形槽，亦可根据实际情况，选择多档位T形槽，可根据实际所述固定件3的尺寸或者固定所述膜片2需要的力度来确定。
如图1及图2所示，本实施例提供一背光模组100，包括有所述背板1、所述膜片2以及所述固定件3。所述膜片2置于所述背板1的背板主体10上。所述固定件3的一端连接至所述挂耳20，而另一端则扣入所述埋线槽12中，以将所述膜片2固定至所述背板1上。在本实施例中，所述膜片2为一光学膜片。
如图1、图2所示，通过挂耳20、固定件3和埋线槽12完成对膜片2的固定。
所述背光模组100还包括有一膜片塞4。如图3所示，所述膜片塞4能够塞入所述挂耳孔22中，以避免灰尘或其他物质侵入所述挂耳孔22中。
在本实施例中，如图3所示，所述膜片塞4为圆形。当然，所述膜片塞4的形状亦可根据所述挂耳孔22（见图2）的形状配置。所述膜片塞4边缘处开设一通槽40，所述通槽40与所述固定件3（见图2）过盈配合。所述膜片塞4外侧有弧形凸起42，所述弧形凸起42能够与所述挂耳孔22的内壁形成干涉配合。因此当所述膜片塞4塞入所述挂耳孔22后才能保证二者之间没有缝隙，避免灰尘或其他物质进入，同时填补所述挂耳孔22，也能提升整体美观。
图4、图5和图6所示为本申请所述背板1的另一实施例，所述背板1的另一实施例与上述实施例的差别在于：所述埋线槽12开设于所述背板1的背面，即底面，如图5所示。
详细来讲，如图4、图5、图6所示，所述背板1具有一直线型的连接槽16’，所述连接槽16’的一部分形成于所述背板主体10的顶面，另一部分形成于所述背板主体10的侧面，其余部分形成于所述背板主体10的底面，并且所述连接槽16’与所述埋线槽12相连通。换句话讲，所述连接槽16’自所述背板主体10的顶面延伸至所述背板主体10的底面，直到与所述埋线槽12衔接起来。
如图6所示，在另一实施例中，本申请背光模组100包括有所述背板1、所述膜片2，以及所述固定件3。所述膜片2置于所述背板1的背板主体10上。所述固定件3的一端连接至所述挂耳20，而另一端则扣入所述背板1底面的所述埋线槽12（见图5）中，以将所述膜片2固定至所述背板1上。本申请背光模组100通过挂耳20、固定件3和埋线槽12能够完成对膜片2的固定。
请参照图7所示，本申请显示装置200包括有如上所述的背光模组100。本申请显示装置200还包括有一显示面板300，例如液晶显示面板或OLED显示面板。
综上所述，本申请所述的背板、背光模组及显示装置的优点在于：通过在膜片的四角设计四个挂耳孔及由每个挂耳孔中均固定引出一个弹性圈，同时配合在背板的对应位置处形成一个挂弹性圈的埋线槽，使得在显示模组装配过程中，只要将固定在膜片四角的弹性圈拉伸固定在背板上对应的埋线槽中，即可轻松实现膜片的固定。因此，本申请的所述背板、背光模组及显示装置避免了原有挂耳和铆柱不易设置，能够有效达到窄边框和四周无边框的效果，适用性广。此外，弹性圈具有一定的弹性，方便安装和拆卸，能够有效达到拉紧固定膜片的效果，可操作性强，可多次反复利用。再者，在背板上对应位置开设埋线槽，可以在实现产品美观的同时减少前框和中框装配过程中的间隙，更加满足极致窄边框的需求。
以上所述仅是本申请的优选实施方式，应当指出，对于本技术领域的普通技术人员，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。
