Description

一种背光模组及显示装置
本申请要求于2017年03月24日提交中国专利局、申请号为201710182211.5、发明名称为“一种背光结构和移动终端”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及显示技术领域，尤其涉及一种背光模组及显示装置。
背景技术
液晶显示装置(Liquid Crystal Display，LCD)是一种被动发光器件，需要背光模组(Backlight Unite，BLU)提供光源使其显示图像。目前，LCD主要采用的背光技术包括：冷阴极管(Cold Cathode Fluorescent Lamp，CCFL)背光和发光二极管(Light Emitting Diodes，LED)背光。由于LED背光具有亮度高、色纯度高、寿命长、可靠性好、无汞污染等多种优点，在背光技术的使用中占有的比重逐渐增大。
其中，LED背光可以分为直下式和侧入式。对于侧入式背光而言，专利CN1655032A公开的背光模组如图1所示，包括导光板10、设置于导光板10侧面的并行排列的多个LED灯13，导光板10的出光面a设置的棱镜板11，该棱镜板11具有棱镜部12。棱镜板11用于对导光板10出射光的方向进行调整。
此外，专利CN104075191A公开的背光模组如图2所示，导光板10以及设置于导光板10一端相邻的两行LED灯13。上述相邻两行LED灯13交错排列，以避免热点(Hotspot)现象造成的画面不均。
由上述可知，现有技术提供的侧入式背光方案中，作为光源的多个LED灯13如图3所示均并排设置于导光板10的一侧，在此情况下如图4所示LED灯13发出的光线通过导光板10均匀的入射至显示面板01。
然而，为了使得LED灯13发出的光线能够均匀入射至导光板10，LED灯13在安装的过程中，需要与导光板10的入光面具有一定的间距，以使得LED灯13具有一定的混光距离。因此，胶框20与导光板10入光面之间需要保证具有一定的间距H。间距H越大，显示装置的屏占比越小。在此基础上，当显示装置在非显示区域设置有其他集成部件，例如摄像头时，显示区域的面积增加，以使得显示装置的屏占比进一步减小，从而不利于提高显示效果。
发明内容
本申请的实施例提供一种背光模组及显示装置,当显示装置的非显示区域中设置有集成部件时，相对现有技术，能够降低显示装置的屏占比。
为达到上述目的，本申请的实施例采用如下技术方案：
第一方面，提供一种背光模组，该背光模组设置于显示面板的非显示侧， 且用于向显示面板提供背光源的背光模组。该背光模组包括胶框。胶框包括多个侧壁，多个侧壁依次首尾相接围成用于容纳显示面板的闭合框架，多个侧壁用于对显示面板进行支撑。此外，多个侧壁中包括具有至少一个凹陷部的第一侧壁，显示面板被第一侧壁支撑的一端具有第一侧面；第一侧面与第一侧壁的形状一致。在此情况下，一方面，可以将具有额外功能的待集成部件设置于上述凹陷部，从而可以减小上述待集成部件占用显示装置非显示区域的面积，进而有利于提高显示装置的屏占比，并实现窄边框或超窄边框设计。另一方面，由于胶框的侧壁能够对背光模组的边界形状进行限定，因此当上述凹陷部设置有待集成部件时，该待集成部件可以直接与显示装置的后壳相接触，避免了该待集成部件与背光模组中其他部件出现堆叠而导致显示装置的厚度较大的问题。
在第一方面的第一种可能的实现方式中，背光模组还包括导光板，该导光板的四周被胶框包围。该导光板具有第二侧面。其中，第二侧面靠近第一侧壁，且与第一侧壁的延伸方向相同；该第二侧面与第一侧壁的形状一致。通过对导光板的一个侧面进行切割，使得导光板具有与第一侧壁延伸方向相同，且形状一致的第二侧面，从而可以增加第一侧壁的凹陷部的深度，进而当待集成部件设置于上述凹陷部后，能够进一步减小上述待集成部件占用显示装置非显示区域的面积。或者，导光板为矩形，从而可以避免导光板切割造成工艺繁琐且次品率上升的问题。
在第一方面的第二种可能的实现方式中或者结合第一方面的第一种可能的实现方式，上述背光模组还包括设置于胶框内，且位于胶框的侧壁上的光源。该光源为显示面板提供显示光线。
结合第一方面的第二种可能的实现方式，光源包括第一子光源和第二子光源。其中，第一子光源位于第一侧壁的凹陷部，第二子光源位于第一侧壁的凸出部。第一子光源的混光距离小于第二子光源的混光距离。由于第一子光源的混光距离较小，制作过程中可以将第一子光源更靠近导光板设置，这样一来，胶框中第一侧壁的凹陷部的深度可以进一步增加，降低胶框对显示装置非现实区域面积的占用率，从而能够空出更多的空间用于设置待集成部件，使得待集成部件占用上述非显示区域的面积进一步减小。
可选的，第一子光源为发光二极管灯条，该灯条具有厚度薄，混光距离短的特点。此外，第二子光源为多个并排设置的发光二极管。该该发光二极管的混光距离大于灯条，但是成本较低，有利于产品的成本控制。
可选的，第一子光源和第二子光源为发光二极管灯条。在此情况下，第二子光源也可以更靠近导光板设置。从而使得胶框中第一侧壁整体靠近显示面板设置，降低了胶框占用非显示区域的面积，有利于提高屏占比。
可选的，第一子光源和第二子光源均为多个并排设置的发光二极管。此外，第一子光源中的发光二极管的高度小于第二子光源中的发光二极管的高度，从而使得第一子光源的混光距离小于第二子光源的混光距离。
结合第一方面的第二种可能的实现方式，在背光模组包括导光板，且导 光板为矩形的情况下，光源为多个并排设置的发光二极管。在此基础上，发光二极管位于第一侧壁上，且除了第一侧壁的凹陷部以外的位置。此外，凹陷部两侧的发光二极管倾斜设置。这样一来，通过将第一侧壁在凹陷部位置的发光二极管移除，且将凹陷部两侧的发光二极管倾斜设置，可以空出部分非显示区域的面积，使得第一侧壁的凹陷部的深度能够进一步加深，从而尽可能的减小第一侧壁在凹陷部与导光板之间的距离，以达到减小胶框占用非显示区域面积的目的。
结合第一方面的第二种可能的实现方式，在背光模组包括导光板，且导光板为矩形的情况下，光源位于胶框中除了第一侧壁以外的侧壁上。在此情况下，上述光源可以为上述发光二极管灯条，或者多个并排设置的发光二极管。优选的光源为灯条。这样一来，即使设置有光源的侧壁远离上述第一侧壁，由于灯条的厚度较小，因此该灯条占用非显示区域的面积也较小。基于此，由于导光板靠近胶框的第一侧壁一侧无需设置光源，因此可以加深第一侧壁凹陷部的深度，达到减小待集成部件占用非现实区域面积的目的。
第二方面，提供一种显示装置，包括第一方面的背光模组。其具有与第一方面相同的技术效果，在此不再赘述。

具体实施方式
本申请的一个方面，提供一种背光模组，设置于如图5所示的显示面板01的非显示侧，且用于向显示面板01提供背光源。上述显示面板01包括相互设置的阵列基板120和彩膜基板121。该阵列基板120和彩膜基板121通过封框胶122对盒密封后形成液晶盒，该液晶盒内设置有液晶层123。
其中，阵列基板120中衬底基板124的尺寸通常较大，即在封框胶122的外侧仍然会有一部分衬底基板124延伸出液晶盒，从而可以在该延伸区域绑定(Banding)驱动芯片或者设置驱动电路。上述衬底基板124可以为玻璃基板或者透明树脂基板。
在此基础上，上述背光模组包括胶框20。该胶框20包括多个侧壁，上述多个侧壁依次首尾相接围城用于容纳显示面板01的闭合框架，该多个侧壁用于对显示面板01进行支撑。具体的，如图6所示，每个侧壁上设置有用于支撑显示面板01的支撑台21。
需要说明的是，由于上述多个侧壁可以构成闭合框架，因此“多个”至少为“三个”。但是通常显示面板01为矩形，因此上述胶框20可以是由四个首尾相接的侧壁构成的框架结构。
在此基础上，上述多个侧壁中如图6所示，包括具有至少一个凹陷部的第一侧壁201。显示面板01被上述第一侧壁201支撑的一端具有第一侧面101。
其中，第一侧面101与第一侧壁201的形状一致。上述第一侧壁201的凹陷部用于设置待集成部件02。
需要说明的是，可以通过异型切割工艺对一整面屏进行切割，从而得到多个独立的具有上述第一侧面101的显示面板01，该第一侧面101凹凸不平。
此外，由于上述切割过程中是对延伸出液晶盒的衬底基板124进行切割，因此该显示面板01的第一侧面101，如图6所示，实际为阵列基板120的衬底基板124采用上述异型切割工艺进行切割的侧面。
基于此，第一侧壁201同样凹凸不平，且第一侧面101与第一侧壁201的形状一致是指，当显示面板01的第一侧面101向内凹陷时，该胶框20在对应上述第一侧面101向内凹陷的位置处，该胶框20的侧壁也向内凹陷。同理，当显示面板01的第一侧面101向外凸出时，该胶框20在对应上述第一侧面101向外凸出的位置处，该胶框20的侧壁也向外凸出。
由上述可知，胶框20的多个侧壁中用于支撑显示面板01的第一侧面101的侧壁为上述第一侧壁201，且第一侧面101与第一侧壁201的形状一致。因此第一侧壁201凹陷部与显示面板01的第一侧面101的凹陷部相对应。这样一来，一方面，可以将待集成部件02，例如摄像头、触控装置等具有额外功能的部件设置于上述凹陷部，从而可以减小上述待集成部件02占用显示装置非显示区域的面积，进而有利于提高显示装置的屏占比，并实现窄边框或超窄边框设计。另一方面，由于胶框20的侧壁能够对背光模组的边界形状进行限定，因此当上述凹陷部设置有待集成部件02时，该待集成部件02可以直接与显示装置的后壳相接触，避免了该待集成部件02与背光模组中其他部件出现堆叠而导致显示装置的厚度较大的问题。
在此基础上，上述背光模组如图6所示还包括导光板10，该导光板10的四周被上述胶框20包围。
具体的，上述导光板10可以如图12所示为矩形。或者为了进一步减小上述待集成部件02占用显示装置非显示区域的面积。优选的，可以对上述导光板10的一个侧面进行切割，以使得导光板10如图7所示具有第二侧面102。其中，第二侧面101靠近上述第一侧壁201。此外，该第二侧面102的延伸方向与第一侧壁201的延伸方向相同，且第二侧面102与上述第一侧壁201的形状一致。
需要说明的是，上述延伸方向相同是指，以导光板10和胶框20均具有四个边为例。在俯视图中上述四个边包括两个沿水平方向延伸的边，以及两个沿竖直方向延伸的边。因此当第二侧面102的延伸方向与第一侧壁201的延伸方向相同时，第二侧面102和第一侧壁201均沿水平方向延伸，或者均沿竖直方向延伸。
此外，为了方便说明图7中将第一侧壁201的厚度省略以实线代替，且只绘制了显示装置的一部分。
在此基础上，上述第二侧面102与上述第一侧壁201的形状一致。因此第一侧壁201凹陷部与导光板的第二侧面102，以及显示面板01的第一侧面101的凹陷部相对应。这样一来，通过对导光板10进行切割，可以增加凹陷部的深度，使得胶框20可以在上述凹陷部进一步向内凹陷。进而当待集成部件02设置于上述凹陷部后，可以进一步减小上述待集成部件02占用显示装置非显示区域的面积。
在此基础上，上述背光模组还包括设置于胶框20内，且位于该胶框20侧壁上的光源30。
基于此，为了进一步增加上述用于设置待集成部件02的第一侧壁201的凹陷部的深度，减小待集成部件02占用显示装置非显示区域的面积，光源30在第一侧壁201凹陷部的混光距离可以小于光源30在第一侧壁201凸出部的混光距离。
为了实现上述目的，优选的，上述光源30如图8所示包括第一子光源301和第二子光源302。其中，图8是以导光板10具有上述第二侧面102，且第 一子光源301和第二子光源302发出的光线入射至上述第二侧面102为例进行的说明。
在此情况下，第一子光源301位于第一侧壁201的凹陷部，从而使得该第一子光源301发出的光线入射至该导光板10的入光面b1或入光面b3。此外，第二子光源302位于第一侧壁201的凸出部，从而使得第二子光源302发出的光线入射至该导光板10的入光面b2。
在此基础上，第一子光源301为发光二极管灯条，例如高功率集成面光源(chip On board Light，COB)灯条。COB灯条具有厚度薄，混光距离短的特点。在制作过程中，可以将COB灯条通过电焊工艺固定于上述胶框20中第一侧壁201靠近导光板10的入光面b1和入光面b3的一侧。此外，第二子光源302可以为多个并排设置的发光二极管。该发光二极管的混光距离大于COB灯条，但是成本较低，有利于产品的成本控制。在制作过程中，可以将上述多个发光二极管制作于柔性电路板(Flexible Printed Circuit，FPC)上，然而将该柔性电路板固定于上述第一侧壁201靠近导光板10的入光面b2的一侧。
由上述可知，由于第一子光源301的混光距离较小，制作过程中可以将第一子光源301更靠近上述入光面b1和入光面b3设置，这样一来，胶框20中第一侧壁201的凹陷部的深度可以进一步增加，降低胶框20对显示装置非现实区域面积的占用率，从而能够空出更多的空间用于设置待集成部件02，使得待集成部件03占用上述非显示区域的面积进一步减小。
此外，当制作成本允许的情况下，上述第一子光源301和第二子光源301可以如图9所示均为发光二极管灯条。这样一来，第二子光源302相对于图8所示的方案而言，可以更靠近上述入光面b1。从而使得胶框20中第一侧壁201整体靠近显示面板01设置，从而降低了胶框20占用非显示区域的面积，有利于提高屏占比。
或者，当光源30包括上述第一子光源301和第二子光源302时。如图10所示第一子光源301和第二子光源302均为多个并排设置的发光二极管，其中第一子光源301中的发光二极管的高度小于第二子光源302中的发光二极管的高度。从而使得第一子光源301的混光距离小于第二子光源302的混光距离。
具体的，上述第一子光源301中的发光二极管可以为0.3T发光二极管。例如3003LED灯(长度为3.0mm，高度为0.3mm)，或者1803LED灯(长度为1.8mm，高度为0.3mm)。而第二子光源302中的发光二极管为0.4T发光二极管，例如3004LED灯(长度为3.0mm，高度为0.4mm)。
同上所述，与图10中的入光面b1相对设置的第一子光源301可以更靠近该入光面b1设置，以增加第一侧壁201的凹陷部的深度。同理，在成本允许的情况下，第一子光源301和第二子光源302中的发光二极管可以均采用高度较小的发光二极管，例如上述0.3T发光二极管。
需要说明的是，本申请对上述胶框20中第一侧壁201的凹陷部、凸出部 的数量以及设置位置不做限定。
上述是以对导光板10进行切割，使其具有与第一侧壁201形状一致的第二侧面102为例，对第一子光源301和第二子光源302的设置方式进行的举例说明。当无需对导光板10进行切割，即该导光板10为矩形时。上述第一子光源301和第二子光源302的设置方式以及类型同上所述，此处不再赘述。
具体的，当上述第一子光源301为发光二极管灯条，例如COB灯条，且第二子光源302为多个并排设置的发光二极管时，以5.5英寸的显示面板为例，对光源30的设计方式进行举例说明。
如图11所示，背光宽度L1，即导光板10的宽度为69.2mm，第一子光源301的长度L3为22.3mm，构成第一子光源301的COB灯条中具有10颗小的灯芯。而该COB灯条的厚度D2为2.8mm。此外，第二子光源302的长度L2为24.6mm。构成该第二子光源302的6个发光二极管的高度D1为3.8mm。COB灯条的厚度D2较小，混光距离短，所以可以将COB灯条更靠近导光板10的入光面设置，进而降低胶框20对非显示区域面积的占用率。
在此基础上，为了使得不同的子光源发出的光线均匀，可以调整流入第一子光源301和第二子光源302的电流大小，使得背光模组向显示面板01提供的正面背光亮度能够达到预设值。例如，当显示装置为手机时，上述预设值可以为11000Lux。
此外，为了使得背光模组提供的光线均匀，还可以根据需要对导光板10上网点的分布密度进行调节。例如当背光模组在一些区域发出的光线亮度较大时，可以适当的降低导光板10上网点的分布密度，反之同理可得。
由上述可知，均是以光源30包括两种不同种类的子光源为例进行的说明。以下，以导光板10为矩形，且光源30由一种类型的子光源构成为例，对该光源30的其他设置方式进行说明。
具体的，例如该光源30由多个并排设置的多个发光二极管构成。基于此，由于上述多个发光二极管需要并排设置，因此为了避免对发光二极管的排列状态造成干涉，第一侧壁201凹陷部的深度有限。
在此情况下，本申请可以通过调整上述光源30中部分发光二极管的摆放角度，以增加上述第一侧壁201凹陷部的深度。具体的，如图13a或图13b所示，上述发光二极管位于第一侧壁201上，且除了第一侧壁201的凹陷部以外的位置。此外，凹陷部两侧的发光二极管倾斜设置。
其中，图13a所示的胶框20具有一个第一侧壁201，而图13b中胶框20具有两个相对设置的第一侧壁201。
这样一来，通过将第一侧壁201在凹陷部位置的发光二极管移除，且将凹陷部两侧的发光二极管倾斜设置，可以空出部分非显示区域C2的面积，使得第一侧壁201的凹陷部的深度能够进一步加深，从而尽可能的减小第一侧壁201在凹陷部与导光板10之间的距离，以达到减小胶框20占用非显示区域C2面积的目的。
或者，在导光板10为矩形的情况下，光源30的设置方式又例如，如图 14a或图14b所示，该光源30可以位于胶框20中除了第一侧壁201以外的侧壁上。
其中，图14a中，设置有光源30的侧壁远离上述第一侧壁201，且与第一侧壁201的延伸方向相同；图14b中，设置有光源的侧壁的延伸方向与第一侧壁201的延伸方向不同。
在此情况下，上述光源30可以为上述发光二极管灯条，或者多个并排设置的发光二极管。其中，优选的光源30为COB灯条。这样一来，即使设置有光源30的侧壁远离上述第一侧壁201，由于COB灯条的厚度较小，因此该COB灯条占用非显示区域C2的面积也较小。基于此，由于导光板10靠近胶框20的第一侧壁201一侧无需设置光源30，因此可以加深第一侧壁201凹陷部的深度，达到减小待集成部件02占用非现实区域C2面积的目的。
需要说明的是，当采用上述任意一种设置方式，且光源30包括多个发光二极管时，还可以根据需要对相邻两个发光二极管的间距进行调节。例如，适当的减小相邻两个发光二极管的间距，以减小该光源30的混光距离，从而减小胶框20占用的非现实区域C2的面积。
此外，阵列基板120的衬底基板124在非显示区域C2可以绑定驱动芯片，如图11所示。该驱动芯片在胶框20上的正投影F的位置与上述第一侧壁201的凸出部的位置重叠。
本申请的另一方面，提供一种显示装置，包括如上所述的任意一种结构的背光模组。具有与前述实施例提供的背光模组相同的技术效果，此处不再赘述。
需要说明的是，上述显示装置可以为任意一种液晶显示装置，例如液晶电视、数码相框、手机、平板电脑、手表或者可视的智能穿戴设备等任何具有显示功能的产品或者部件。
以上所述，仅为本申请的具体实施方式，但本申请的保护范围并不局限于此，任何在本申请揭露的技术范围内的变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以权利要求的保护范围为准。
