 本发明的实施方式
下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
请参阅图1，其为本申请实施例背光模组的第一种结构示意图。背光模组包括支撑部11、导光板12以及光源13。
支撑部11的一端具有两个第一缺口110a以及第一凸起部111，两个第一缺口110a位于第一凸起部111的两侧。两个第一缺口110a对称地设置于第一凸起部111的两侧，即两个第一缺口110a的尺寸相同。第一凸起部111为矩形。支撑部11包括背板以及设置于背板上的胶框。
请结合图1和图2，图2为图1所示背光模组中的导光板12靠近第一凸起部111的侧面的示意图。导光板12靠近第一凸起部111的侧面设置有入光面121以及位于入光面121两侧的非入光面122，入光面121与第一凸起部111相对设置，非入光面122与第一缺口110a相对设置。
光源13的出光面贴附于入光面121，使得光源13与第一凸起部111相对设置。光源13为发光二极管。
请参阅图3，其为图1所示背光模组的局部放大图。由于光源13不设置于非入光面122和第一缺口110a靠近导光板12的第一平面1101之间，使得非入光面122与第一缺口110a靠近导光板12的第一平面1101之间的垂直距离D1减小，从而使得第一缺口110a的深度D2增大，从而使得背光模组实现窄边框化。
本申请实施例背光模组通过将光源设置于支撑部的第一凸起部以及导光板的入光面之间，而在第一凸起部两侧的第一缺口和导光板的非入光面之间不设置光源，以实现背光模组的窄边框化。
请参阅图4，其为本申请实施例背光模组的第二种结构示意图。图4所示背光模组与图1所示背光模组基本相似，不同之处在于，入光面121围合成凹陷缺口121a。入光面121围合成凹陷缺口121a使得导光板12在凹陷缺口121a的两侧区域有入射光以提高背光模组的发光效果。
如图5所示，图5为图4所示背光模组的局部放大图。凹陷缺口121a为梯形。入光面121包括第一入光面1211、第二入光面1212以及连接第一入光面1211以及第二入光面1212的中间入光面1213。中间入光面1213垂直于导光板12所在平面且与第一方向平行，第一入光面1211和第二入光面1212相对设置。第一入光面1211与中间入光面1213之间的夹角A1的取值范围为大于或等于135度且小于180度，第二入光面1212与中间入光面1213之间的夹角A2的取值范围为大于135度且180度。第一入光面1211与中间入光面1213之间的夹角A1小于135度会使得光源13在第二方向上占用的空间增大，从而导致第一凸起部111在第二方向上的长度增加，不利于背光模组实现窄边框；第一入光面1211与中间入光面1213之间的夹角A1为180度时，会导致导光板12在凹陷缺口121a两侧的区域没有入射光，第二入光面1212与中间入光面1213之间的夹角的取值范围同理。第二方向为第一凸起部111指向凹陷缺口121a的方向，第一方向为第一凸起部111指向第一缺口110a的方向，第一方向与第二方向共平面且垂直。
第一入光面1211、第二入光面1212以及中间入光面1213均为平整的平面以使得光源13的出光面能紧密地贴附于入光面121上，入光面121与光源13之间的空气最少，以避免光源13发出的光在空气中传播过程中发生损失。
进一步地，第一入光面1211与中间入光面1213之间的夹角A1等于第二入光面1212与中间入光面1213之间的夹角A2，以使得射入至靠近第一入光面1211一侧的导光板12中的入射光量与射入至靠近第二入光面1212的一侧导光板12中的入射光量相同，以进一步地提高背光模组的出光效果。
凹陷缺口121a靠近第一凸起部111的第一边1101在第一方向上的长度H1等于第一凸起部111靠近凹陷缺口121a的第二边1111在第一方向上的长度H2，以使得入光面121在第一方向上可以利用的空间更多，可以设置更多的光源13以提高背光模组的发光效果。
进一步地，如图4所示，第一凸起部111在第一方向上的长度H3与支撑部11在第一方向上相对的两侧的垂直距离H4的比值的取值范围为0.5-0.99，以进一步地使入光面121在第一方向可利用的空间增多，从而提高背光模组的发光效果。
请参阅图6，其为本申请实施例背光模组的第三种结构示意图。图6所示背光模组与图4所示背光模组基本相似，不同之处在于，第一凸起部111为倒梯形。第一凸起部111为倒梯形使第一缺口110a的尺寸更大。
请参阅图7及图8，图7其为本申请实施例液晶显示器的第一种结构示意图，图8为图7所示液晶显示器的局部放大示意图。液晶显示器包括图4所示背光模组10以及液晶显示面板20。
液晶显示面板20具有一台阶区以及绑定于台阶区的柔性印刷电路板220，台阶区对应第一缺口110a的位置设置有第二缺口200a，台阶区对应第一凸起部111的位置设置有第二凸起部211，第二缺口200a位于第二凸起部211的两侧，两个第二缺口200a远离第二凸起部211的边缘设置有绑定区210b，两个柔性印刷电路板220分别绑定于绑定区210b并依次穿过第二缺口200a和第一缺口110a以弯折至背光模组10背向液晶显示面板20的一侧。液晶显示面板20还具有一显示区AA（Active Area），显示区AA位于台阶区远离第二凸起部211的一侧。
需要说明的是，背光模组10还包括光学薄膜（未示出）以及遮光膜（未示出），光学薄膜位于导光板的出光面所在侧，光学薄膜包括用于聚光的增光片以及使光均匀的扩散片；遮光膜位于光学薄膜远离导光板的一侧，遮光膜用于限定背光模组的发光区域VA。
请参阅图8和图9，图9为图8所示液晶显示器沿B-B切线和C-C切线的剖面图。液晶显示器的下边框长度为在第二方向（第二凸起部211指向显示区AA的方向）上的垂直距离a、垂直距离b以及垂直距离c之和。其中，垂直距离a为在第二方向上液晶显示面板显示区AA的下边缘到背光模组发光区域VA的下边缘的垂直距离，垂直距离b为在第二方向上背光模组发光区域VA的下边缘到背光模组10的下边缘（即第一凸起部的远离背光模组10发光区域VA的边缘）的垂直距离，垂直距离c为在第二方向上背光模组10的下边缘到柔性印刷电路板220弯折段远离第一缺口110a的边缘的垂直距离。本申请实施例液晶显示器通过使柔性印刷电路板的弯折段部分或完全位于第一缺口110a和第二缺口200a内，以减小垂直距离c，从而使得液晶显示器的下边框长度减小。
进一步地，柔性印刷电路板220的弯折顶点E位于第一缺口110a内以进一步地使液晶显示器具有窄边框以及高屏占比，弯折顶点E为柔性印刷电路板220的弯折段上远离第一凸起部111的点。
液晶显示面板20在背光模组10上的垂直投影位于背光模组10内以使背光模组10起到保护液晶显示面板20的作用。
请继续参阅8，本申请液晶显示面板20还包括驱动芯片230，驱动芯片230设置于台阶区且位于第二凸起部211远离显示区AA的边缘和显示区AA靠近第二凸起部211的边缘之间，使得驱动芯片230靠近显示区AA的边缘和显示区AA靠近驱动芯片230边缘之间的距离以及驱动芯片230远离显示区AA的边缘和第二凸起部211远离显示区AA的边缘之间的距离均增大，使得液晶显示器在实现窄下边框时，不会出现由于驱动芯片230到组成液晶显示面板20的阵列基板的切割线距离过近而导致驱动芯片压合后电性不良问题以及驱动芯片距离显示区过近而导致液晶显示面板密封不良问题。
本申请液晶显示面板还包括外围走线，外围走线从显示区AA的两侧延伸至驱动芯片230以与驱动芯片230电性连接，外围走线包括倾斜走线240，为了使倾斜走线240、从显示区AA延伸出的扇形走线以及设置于绑定区域210b中的金属端子（未示出）有足够的布设空间。驱动芯片230靠近显示区AA的边缘到显示区AA靠近驱动芯片230的边缘之间的距离大于驱动芯片230远离显示区AA的边缘到第二凸起部211远离显示区AA的边缘之间的距离。例如，驱动芯片230完全或部分位于第一凸起部211上，或驱动芯片230位于第一凸起部211之外且位于台阶区之内。
请参阅图10，其为本申请实施例液晶显示器的第二种结构示意图。其与图7所示液晶显示器的区别仅在于，第二凸起部111和第一凸起部211均为倒梯形，以使得第二缺口200a和第一缺口110a更大，更有利于液晶显示器实现窄边框以及高屏占比；柔性印刷电路板220具有和第一凸起部111相配合的缺口，该缺口为矩形或梯形，柔性印刷电路板220的缺口两侧具有第一连接部2201，两个第一连接部2201绑定于绑定区210b且与柔性印刷电路板220的主体部2202连接以向主体部2202输入信号。
本申请实施例液晶显示器通过台阶区具有第二凸起部和第二缺口的液晶显示面板配合具有第一凸起部和第一缺口的窄边框背光模组，且柔性印刷电路板依次穿过液晶显示面板的第二缺口和背光模组的第一缺口以使液晶显示器具有窄边框和高屏占比。
