具体实施方式
相关技术中，显示装置中侧入式背光源的灯条的电源端子通过一条电源线与电路板连接，为兼顾电源线的电阻，电源线在面板厚度方向上的几何尺寸较大，即电源线在横截面的几何尺寸较大，电源线较粗，且在电源线连接电源端子后需要折弯以连接至位于显示模组背面的电路板，导致显示装置边缘厚度较厚。这样的结构在微型显示装置的生产过程中，要实现边框位置的超薄效果非常困难。
基于此，本公开实施例提供了一种显示模组和显示装置，以减薄显示装置的边框厚度。下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。
如图1至图5所示，本公开实施例提供了一种显示模组，包括：
背光组件，背光组件包括背光背板122、背光模组124和背光源121，背光背板122具有容置背光模组124的容置腔，背光模组124位于容置腔内，背光源121位于容置腔内且位于背光模组124的侧面，背光源121包括灯条121a和电源端子121b；
第一控制电路板2，固定于背光背板122背离背光模组124的表面；
连接线组件，连接线组件包括通过转接结构33串联的至少两条连接线，与第一控制电路板2连接的连接线为第一连接线31，与电源端子121b连接的连接线为第二连接线32，转接结构32固定于背光背板122背离背光模组124的表面，第一连接线31的横截面的几何尺寸大于第二连接线32的横截面的 几何尺寸。以下均以连接线组件包括两条连接线为例进行说明，在实际应用时，连接线组件不限于两条连接线，可以根据需要设计多条连接线。
图1为显示模组的背面结构示意图，以图1中M-M的路径展开显示模组形成剖面，如图2至5所示，沿显示模组的厚度方向，第二连接线32的尺寸小于第一连接线31的尺寸，即第二连接线32的横截面的几何尺寸小于第一连接线31的横截面的几何尺寸。
第一控制电路板2为显示模组整体的控制电路板，在显示模组中能够控制各电元器件工作，其中即包括显示面板的显示功能和背光组件中背光源的点亮功能。具体地，第一控制电路板2可以通过连接线组件与电源端子121b电连接，以实现对背光组件的控制。
对比于相关技术中显示模组的较大尺寸的连接线，本公开实施例提供的连接线组件分为三部分：第一连接线31、第二连接线32以及用于连接第一连接线31和第二连接线32的转接结构33。图1展示了第一连接线31、第二连接线32、转接结构33在显示组件背面的结构，第一连接线31一端连接转接结构33，另一端连接第一控制电路板2，第二连接线32一端连接转接结构33，另一端连接电源端子121b，实现了第一控制电路板2与背光组件的物理连接。
可选地，在本公开实施例提供的上述显示模组中，第一连接线31和第二连接线32至少一种可以为多路信号线。并且，第二连接线32的单位长度电阻一般小于第一连接线31的单位长度电阻，以能够保证信号的正常传递。
具体地，本公开实施例提供的上述显示模组在组装过程中，可以先将背光组件中的背光源121和背光模组124置于背光背板122的容置腔内，在背光背板122的背面固定第一控制电路板2，以及用于连接第一连接线31和第二连接线32的转接结构33固定于背光背板122的背面，而连接电源端子121b的第二连接线32会在显示模组的边缘发生弯折以连接位于背光背板122背面的转接结构33和位于背光背板122之内的电源端子121b。为了减小整个显示模组边缘位置的厚度，沿显示组件的厚度方向，第二连接线32的尺寸小于第一连接线31的尺寸即发生弯折的第二连接线32的横截面的几何尺寸小于第 一连接线31的横截面的几何尺寸，能够有效降低显示模组在边缘位置的厚度。
综上，本实施例提供的上述显示模组，背光组件中的电源端子121b与第一控制电路板2之间通过连接线组件连接，连接组件中的第一连接线31和第二连接线32均可以选用多端连接线，且在保证电阻的情况下，沿显示组件的厚度方向上减小第二连接线32的尺寸，使第二连接线32的尺寸小于第一连接线31，有效降低整个显示模组边缘位置的厚度，有利于实现显示装置的超薄化制造。
其中，上述转接结构33固定于背光背板122的背面即背离背光模组124的表面，具体的固定方式可以有多种方式。例如，如图4中转接结构33可以通过双面胶332粘贴于背光背板122的背面，此处的双面胶332可以为导热绝缘石墨片双面胶，也可以是普通的绝缘双面胶，这种连接方式简单方便，且能够保持背光背板122容纳腔内腔的整洁；或者，如图2、5或6中转接结构33也可以通过螺钉331与背光背板122的背面连接，这种连接方式需要在背光背板122的背面打孔；或者，转接结构33通过卡接组件与背光背板122的背面连接。
需要说明的是，当转接结构33通过卡接组件与背光背板122连接时，卡接组件可以是任一种能够实现卡接的结构，例如环形卡接、悬臂卡接都可以，且卡接组件可以实现可拆卸连接，方便安装于拆卸。
作为一种可选的实施例，上述第一连接线31和第二连接线32均可以选用多路信号线，且第二连接线32每路的单位长度电阻小于第一连接线31每路的单位长度电阻。
需要说明的是，在具体的生产组装中，可以先组装转接结构33、第二连接线32与电源端子121b的连接结构，在后期再进行转接结构33与第一连接线31、第一控制电路板2之间的连接结构组装。
一种具体的实施例中，如图3所示，第二连接线32可以包括相互垂直的第一连接部321和第二连接部322，其中，第一连接部321平行于背光背板122的底面以连接转接结构33，第二连接部322平行于电源端子121b且与电 源端子121b连接。
可选地，在本公开实施例提供的上述显示模组中，为了便于电源端子121b与第二连接部322连接，如图3所示，电源端子121b一般固定于灯条121a面向背光背板122的底面的一侧，背光背板122由位于背光模组124下方的底面和围绕背光模组124侧周设置的侧面构成，即可以认为电源端子121b固定在灯条121a的下方；这样，在背光背板122的底面的电源端子121所在区域设置通孔1221，电源端子121b可以通过通孔1221与第二连接线322连接，而避免采用第二连接线322需要绕线至背光背板122的容置腔开口后与电源端子121b连接的复杂布线方式。
具体地，由于背光源121设置在背光模组124的一侧边，可以将背光源121中的电源端子121b设置在灯条121a的一侧边缘，这样，覆盖电源端子121b的通孔1221位于背光背板122的边缘，可以是如图1所示靠近显示模组一角落。
具体地，第一连接部321用于连接上述转接结构33，因此，第一连接部321可以设置于背光背板122的背面，且以平行于背光背板122背面的形式设置。第二连接部322垂直于第一连接部321，自第一连接部321远离转接结构33的一端延伸至背光背板122的通孔1221。需要说明的是，第二连接线32为一体结构，第一连接部321和第二连接部322的连接处可能并不是严格的直角结构，此处的第一连接部321和第二连接部322的垂直关系指的是二者的延伸方向是相互垂直的。
可选地，在本公开实施例提供的上述显示模组中，第二连接线32的第二连接部322与电源端子121b可以插接、锡焊或通过各向异性导电胶连接，可以根据实际需求选择合适的连接方式。图2至图6仅是以第二连接部322与电源端子121b通过插接的方式连接的方式进行图示，其中插接处见图3中三角框标注处。
可选地，在本公开实施例提供的上述显示模组中，如图3所示，电源端子121b与第二连接部322的连接端可以穿过通孔1221，且位于背光背板122 背离背光模组124的一侧。即电源端子121b伸出通孔1221，与第二连接部322的连接端位于背光背板122的外部，以便于电源端子121b与第二连接部322的组装连接。或者，电源端子121b与第二连接部322的连接处也可以位于通孔1221的内部，或背光背板122的容置腔内部，在此不做限定。
可选地，在本公开实施例提供的上述显示模组中，如图2、4、5和6所示，背光模组124一般包括依次层叠设置的光学膜112、导光板113和反射片114；光学膜112位于导光板113背离背光背板122的一侧，反射片114位于导光板113面向背光背板122的一侧。
可选地，在本公开实施例提供的上述显示模组中，如图5所示，还包括：显示面板111、第二控制电路板131和柔性电路板132；
显示面板111位于背光模组124背离背光背板122的一侧，第二控制电路板131固定于背光背板122背离背光模组124的表面，柔性电路板132连接于显示面板111和第二控制电路板131之间。
可选地，在本公开实施例提供的上述显示模组中，如图5所示，背光组件还可以包括背光框架123，背光框架123具有用于承载显示面板的支撑部和与支撑部连接的框架，框架位于背光背板122的侧面外侧，外侧是指背光背板122的侧面远离背光模组124的一侧，可以认为框架围绕背光背板122的外侧一周设置；背光框架123背离背光模组124的外侧可以设有容置柔性电路板132的安装凹槽。
具体地，柔性电路板132设置于第二控制电路板131的一侧与第二控制电路板131实现电性连接，柔性电路板132沿背光模组124的厚度方向延伸至显示面板111的前面与显示面板111电性连接。
可选地，在本公开实施例提供的上述显示模组中，连接线组件还可以包括连接于第二控制电路板131与转接结构33之间的第三连接线(图中未示出)，通过第三连接线可以将转接结构33接收到的第一控制电路板2发送的信号传输至第二控制电路板131，以通过柔性电路板132发送至显示面板111控制显示。
具体地，在本公开实施例提供的上述显示模组中，如图5所示，第二控制电路板131可以设置于第二连接线32的弯折处，也可以与第二连接线32的弯折处具有一定的间距，在此不做限定。
具体地，在本公开实施例提供的上述显示模组中，如图5所示，还可以包括设置于背板框架123侧面的显示外框116，显示外框116的一部分平行于背光框架123的支撑部，并包覆支撑部和显示面板111的非显示区域，显示外框116另一部分平行于背光框架123的框架并包覆框架。
可选地，在本公开实施例提供的上述显示模组中，如图5所示，还可以包括位于背光背板122背离背光模组124的一侧即位于背光背板122的背面，且覆盖第二控制电路板131的保护盖14。即在第二控制电路板131背离背光背板122的一侧设置有覆盖第二控制电路板131的保护盖14。
可选地，在本公开实施例提供的上述显示模组中，如图5所示，第二控制电路板131在背光背板122上的正投影可以覆盖第二连接线32的第二连接部322与电源端子121b连接位置处在背光背板122上的正投影。保护盖14还可以覆盖电源端子121b与第二连接线32的连接处。
具体地，保护盖14不但能够保护第二控制电路板131，还能够覆盖第二连接线32与电源端子121b的连接区域，起到保护作用。
可选地，在本公开实施例提供的上述显示模组中，如图5所示，上述保护盖14位于整个背光背板122的边缘部分与上述显示前框116可以相抵接。
基于同样的发明思路，如图6和7所示，本公开实施例还提供一种显示装置，包括整机前框4、整机后壳5以及如上述实施例提供的任一种显示模组；其中，整机前框4和整机后壳5扣合连接于显示模组的外侧，且整机前框4设置有露出显示模组显示区域即正面的窗口。
可选地，在本公开实施例提供的上述显示装置中，如图6所示，整机前框4和整机后壳5的连接处可以位于显示模组的侧边(图6中圆圈所示处)，使得上述显示模组的结构能够具有较为轻薄的边缘，所以，整机前框4和整机后壳5的连接处也较为轻薄，降低了整个显示装置边缘厚。
如图7所示为一种具体的显示装置，在显示装置的底部还设置有底座6。
显然，本领域的技术人员可以对本公开实施例进行各种改动和变型而不脱离本公开的精神和范围。这样，倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
