Description

背光模组以及显示装置 技术领域
本公开的实施例涉及一种背光模组以及显示装置。
背景技术
目前，液晶显示器多采用背光模组向显示面板提供光源，背光模组中采用导光板将光源发出的光均匀地导向显示面板。
现有的导光板为板状，其光的损耗在30％左右，并且在导光板侧面容易产生漏光，需要额外加入黑胶带来遮蔽漏光区域，导致光的输出率较低，影响显示品质。
另外，板状结构的导光板没有相应位置容纳光源器件，对产品的窄边框设计形成限制。

导光板；以及
PCB基板，位于导光板两侧，所述PCB基板上设有多组光源器件，每组光源器件包括至少一个光源器件；

本公开的至少一个实施例还提供一种显示装置，其包括上述背光模组。
根据本公开的一个实施例，该显示装置还包括上基板和下基板，所述上基板和所述下基板对盒设置；上偏光片，设置于所述上基板的上表面；彩膜层，设置于上基板的下表面；线栅偏光膜和阵列层，设置于所述下基板的内表面；取向层，设置于所述上下基板内表面；液晶层，夹设于所述上基板和所述下基板之间；封框胶；密封所述液晶层周边；以及纳米颗粒，设置于所述下基板的外表面，且所述纳米颗粒的表面设有反射板；其中，导光板设置为下基板。
附图说明
为了更清楚地说明本公开实施例的技术方案，下面将对实施例的附图作简单地介绍，显而易见地，下面描述中的附图仅仅涉及本公开的一些实施例，而非对本公开的限制。
图1为本公开实施例一背光模组结构示意图；
图2为本公开实施例一背光模组中三角形凸起结构示意图；

具体实施方式
为使本公开实施例的目的、技术方案和优点更加清楚，下面将结合本公开实施例的附图，对本公开实施例的技术方案进行清楚、完整地描述。显然，所描述的实施例是本公开的一部分实施例，而不是全部的实施例。基于所描述的本公开的实施例，本领域普通技术人员在无需创造性劳动的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。
实施例一
本公开的一个实施例提供一种背光模组，如图1～4所示，该背光模组， 包括：
导光板1，以及PCB基板2，所述PCB基板2位于导光板1一侧，所述PCB基板2上设有多个光源器件组3；
所述导光板1朝向PCB基板2的一侧设有多个凹槽11，用于容纳光源器件组3；凹槽11中的内壁上设有多个凸起111。
每个光源器件组3至少包括一个光源器件，在附图中以每个光源器件组包括一个光源器件进行图示说明。
该凸起111由与导光板1相同的材料制作，直接形成在凹槽11的内壁上。即在导光板1上形成凹槽11的同时，一并形成凸起111的图形。
本实施例中将导光板的一侧设置成凹槽结构，可以容纳光源器件，最大程度节省光源器件的占用面积，实现产品的窄边框设计。
另外，本实施例中的凹槽11的内壁上设有多个凸起111，光源器件发出的光会经过这些凸起进而发生反射，可利用光源器件的侧面发出的光，提高光的利用率，进一步用更少的光源器件实现所需亮度，在节能的同时可有效降低对光源器件的散热负担，进而降低光学模组的内部温度，提高产品的使用寿命。
需要说明的是，该凸起的数量可根据实际需求而定，其结构可以为多边形或弧形，当然，也可以为其他几何形状。
本公开实施例中的多边形可为以三角形和四边形，该四边形可以为矩形、梯形或其他不规则四边形；该弧形可以为半圆形，也可以为半椭圆形，或者其他不规则弧形。
该凸起111可连续设置或间隔设置在凹槽的内壁上，该两种设置方式都能使光经过凸起时发生更多的反射，提高光的输出率。
另外，本实施例中的光源器件组包括至少一个LED灯，当然，除了LED灯外，还可以采用其他类型的发光元件用于光源器件组。
为了使光源器件组均被容纳在凹槽中，设置凹槽的数量与光源器件组的数量相等。
为了保障光源器件组发出的光可以于凸起发生反射，并且为光源器件组提供良好的散热，光源器件组设置得距凹槽内壁预定距离。
实施例二
图5示出了根据本公开的第二实施例的结构。第二实施例提供的背光模组与实施例一的区别在于，该凸起111由透镜薄膜制作，所述透镜薄膜粘贴在凹槽11的内壁上。即，在导光板1上形成凹槽11即可，采用透镜薄膜粘贴的形式，将透镜薄膜凸起设置在凹槽的内壁上。
同样，该透镜薄膜也可以为多边形或弧形，该多边形可以为三角形和四边形，该四边形可以为矩形、梯形或其他不规则四边形；
该弧形可以为半圆形，也可以为半椭圆形，或者其他不规则弧形。
该透镜薄膜可采用不同的形状以产生不同形状的凸起，来进一步使光发生更多的反射，提高光的有效使用率。
本公开的至少一个实施例还提供一种显示装置，包括上述的背光模组。该显示装置还包括上基板20和下基板30，所述上基板20和所述下基板30对盒设置；上偏光片21，设置于所述上基板20的上表面；彩膜层22，设置于上基板20的下表面；有线栅偏光膜23和阵列层26，设置于所述下基板的内表面；取向层24，设置于所述上下基板内表面；液晶层25，夹设于所述上基板和所述下基板之间；封框胶29,密封所述液晶层25周边；以及纳米颗粒27，设置于所述下基板的外表面，且所述纳米颗粒的表面设有反射板28；其中，导光板设置为下基板。
在这种显示装置中，导光板起下基板和导光板的作用，并且采用线栅偏光膜取代现有贴附的偏光片来实现对光线的起偏，解决了现有的显示器件厚度过大的问题，实现显示装置的超薄化设计。
该显示装置可以为液晶显示屏、液晶显示器、平板电脑、笔记本、电子书等电子产品中的任何一种。
本公开的实施例提供一种背光模组以及显示装置，通过将导光板的一侧设有多个凹槽容纳光源器件组，并且在凹槽的内壁上设有多个凸起，可利用光源器件侧面发出的光，使得能够提高光的利用率，用更少的光源器件实现需求亮度，在节能的同时可有效地降低对光源器件组的散热负担，进而降低模组的内部温度，提高产品的使用寿命；另外，设置可容纳光源器件组的凹槽，进一步缩小光源器件组的占用面积，可实现产品的窄边框设计。
以上所述仅是本公开的示范性实施方式，而非用于限制本公开的保护范围，本公开的保护范围由所附的权利要求确定。
