Description

光源组件、背光模块及液晶显示器 技术领域
本发明属于液晶显示技术领域，具体地讲，涉及一种光源组件、背光模块及液晶显示器。
背景技术
随着信息社会的发展，人们对平板显示器的需求得到了快速的增长。液晶显示器(Liquid Crystal Display，简称LCD)具有体积小、功耗低、无辐射等特点，在当前的平板显示器市场占据了主导地位。
目前，按照入光方式的不同，液晶显示器主要被分为直下式液晶显示器和侧入式液晶显示器。在传统的直下式液晶显示器中，所采用的LED只有一个出光面(即顶出光面)，在不采用二次透镜的情况下，控光区域非常狭窄，因此传统的直下式液晶显示器中的LED都具有二次透镜来拓展控光区域，达到减少灯数量且降低成本的目的。然而，二次透镜的加入，会增加透镜成本和透镜打件成本，且控光区域近似圆形而非方形。
现如今，在薄型化大尺寸液晶显示器中，HDR(高动态对比度)成为衡量高端液晶显示器的一个重要指标。对于HDR液晶显示器，背光分区越多，单个背光分区的控光区域越接近方形，HDR越好。然而，如上所述，由于现有的LED加配二次透镜之后，形成的控光区域近似圆形，因此会影响HDR。为了解决该问题，现有通常采用四面发光LED，其控光区域呈方形，能够有效提升液晶显示器的HDR。然而，四面发光LED价格昂贵，如何减少四面发光LED的数量成为一个亟需解决的技术问题。
发明内容
为了解决上述现有技术的问题，本发明的目的在于提供一种能够减少使用四面发光LED的光源组件、背光模块及液晶显示器。
根据本发明的一方面，提供了一种光源组件，其包括：供电板；设置于所述供电板上的至少两个点光源；设置于所述供电板上且位于彼此相邻的两个点光源之间的反光块，所述反光块用于将所述点光源出射至其上的光线沿着远离所述供电板的方向反射出去。
可选地，所述反光块具有朝向所述点光源凹陷的曲面。
可选地，所述反光块的截面形状呈类三角形，所述类三角形的朝向所述点光源的边为内凹的曲边。
可选地，所述点光源为呈长方体的LED灯，所述LED灯的四个侧面出射光线。
可选地，所述反光块由聚碳酸酯、聚酰胺或聚邻苯二甲酰胺制成。
根据本发明的另一方面，还提供了一种背光模块，其包括：权利要求1至5任一项所述的光源组件；光学板，与所述供电板相对设置，所述供电板的设置所述点光源的表面朝向所述光学板，所述反光块用于将所述点光源出射至其上的光线反射至所述光学板。
可选地，所述背光模块还包括：反射片，设置于所述供电板与所述点光源和所述反光块之间。
可选地，所述点光源和所述反光块的数量相同，所述点光源和所述反光块阵列排布，并且在阵列行方向和列方向上所述点光源和所述反光块交替设置。
根据本发明的又一方面，又提供了一种液晶显示器，包括相对设置的上述背光模块和液晶面板。
本发明的有益效果：通过在点光源之间设置作用相当于点光源的反光块，这样在制作同样数量的点光源时，可以节省点光源的数量，从而大幅度降低成本。
附图说明
通过结合附图进行的以下描述，本发明的实施例的上述和其它方面、特点和优点将变得更加清楚，附图中：
图1是根据本发明的实施例的光源组件的结构示意图；
图2是根据本发明的实施例的背光模块的结构示意图；
图3是根据本发明的实施例的背光模块中的光源组件的俯视图；
图4是根据本发明的实施例的液晶显示器的结构示意图。
具体实施方式
以下，将参照附图来详细描述本发明的实施例。然而，可以以许多不同的形式来实施本发明，并且本发明不应该被解释为限制于这里阐述的具体实施例。相反，提供这些实施例是为了解释本发明的原理及其实际应用，从而使本领域的其他技术人员能够理解本发明的各种实施例和适合于特定预期应用的各种修改。
在附图中，为了清楚器件，夸大了层和区域的厚度。相同的标号在整个说明书和附图中可用来表示相同的元件。
图1是根据本发明的实施例的光源组件的结构示意图。
参照图1，根据本发明的实施例的光源组件10包括：供电板101、两个点光源102、一个反光块103。
供电板101可例如是一印刷电路板，但本发明并不限制于此。两个点光源102彼此间隔地设置于供电板101，这样可以使供电板101向这两个点光源102提供电能。反光块103设置于两个点光源102之间，反光块103能够将每个点光源102出射至其上的光线沿着远离供电板101的方向反射出去。也就是说，此时的反光块103相当于一个点光源102。
在本发明中，点光源102的数量并不以两个为限，其可以根据实际需求而设置任意数量。同样地，在本发明中，反光块103的数量并不以一个为限，其根据点光源102的数量而设置，其数量的设置满足的条件是：彼此相邻的两个点光源102之间设置一个反光块103。
作为一个示例性实施方式，反光块103具有朝向点光源102凹陷的曲面1031。进一步地，作为一个示例性实施方式，反光块103的截面形状呈类三角 形，所述类三角形的朝向点光源102的边为内凹的曲边。当然本发明的反光块可以具有其他结构，其只要能够将点光源102出射至其上的光线沿着远离供电板101的方向反射出去即可，诸如反光块103的截面形状为三角形。
此外，反光块103可以由聚碳酸酯、聚酰胺、聚邻苯二甲酰胺制成或者其他具有高反射率的白色树脂材料制程，但本发明并不限制于此。
在本实施例中，优选地，点光源102为呈长方体的LED灯，所述LED灯的四个侧面出射光线。应当说明的是，本发明的点光源并不限制于这里给出的点光源。
综上所述，在本实施例的光源组件10中，通过在点光源102之间设置一个可以充当点光源的反光块103，这样在制作同样数量的点光源102时，可以节省点光源102的数量，从而大幅度降低成本。
图2是根据本发明的实施例的背光模块的结构示意图。
参照图2，根据本发明的实施例的背光模块1包括：光源组件10、背框11、光学板12、反射片13及光学膜片14。
光源组件10设置于背框11中，光学板12设置于背框11之上，从而使光源组件10的供电板101的安装点光源102和反光块103的表面朝向光学板12，这样，反光块103将每个点光源102出射至其上的光线反射至光学板12，光学膜片14设置于光学板12上。
光学板12可例如是扩散板，但本发明并不限制于此。光学膜片14的数量并不限制于图2中所示出的一张，其可以根据实际需求而设置任意数量，并且光学膜片14可能实际需求的功能而被设定。例如，光学膜片14可以是增亮膜片、扩散膜片等。
反射片13设置于供电板101的安装点光源102和反光块103的表面上。反射片13用于将点光源102和反光块103出射至其上的光线反射至光学板12，以提高光线的利用率。因此，反射片13的设置是一种优选地技术方案，作为本发明的其他实施方式，反射片13不设置也可以。
在本实施例的背光模块1中，根据实际需求增加了点光源102和反光块103的数量。图3是根据本发明的实施例的背光模块中的光源组件的俯视图。在图3中，作为示例，以方框表示点光源102，具有一竖线的方框表示反光块103。参照图3，优选地，点光源102和反光块103的数量相同，这些点光源102和反光块103一并阵列排布，并且在阵列行方向和列方向上，点光源102和反光块103交替设置。这里的点光源102和反光块103的数量和排列是一种优选方案。作为本发明的其他实施方式，若干点光源102阵列排布，将阵列排布后的若干点光源102中的至少一个点光源102替换为反光块103即可。
图4是根据本发明的实施例的液晶显示器的结构示意图。
参照图4，根据本发明的实施例的液晶显示器包括：背光模块1和液晶面板2。背光模块1和液晶面板2相对设置，背光模块1向液晶面板2提供均匀的面显示光线，从而液晶面板2借由该均匀的面显示光线显示影像。
综上所述，根据本发明的实施例，利用作用相当于点光源的反光块替换点光源，可以节省点光源的使用量，从而节省成本。
虽然已经参照特定实施例示出并描述了本发明，但是本领域的技术人员将理解：在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下，可在此进行形式和细节上的各种变化。
