Description

一种背光模组以及显示装置
技术领域
本发明涉及显示技术领域，特别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电源，背光模组中采用导光板来将光源发出的光均匀发散开来。
现有的导光板为板状，其光的损耗在30％左右，并且导光板侧面容易发生漏光现象，需要额外加入黑胶带来掩盖漏光区域，导致光的输出率较低，影响产品的显示品质。
另外，板状结构的导光板没有相应位置容纳光源器件，限制产品的窄边框设置。
发明内容
(一)所要解决的技术问题
本发明所要解决的技术问题是提供一种背光模组以及显示装置，以克服现有技术中光源利用率低下，容易造成光源光衰严重导致影响产品显示品质等缺陷。
(二)技术内容

导光板以及位于导光板两侧的PCB基板，所述PCB基板上设有若干个光源器件；
所述导光板朝向PCB基板的两侧分别设有若干个用于容纳光源器件的凹槽；
所述凹槽中两个相对的内壁上设有若干个凸起。
优选地，所述凸起由导光板制作，直接形成在凹槽的内壁上。

优选地，该显示装置还包括形成对盒的上基板和下基板，所述上基板的上表面设有上偏光片，其上基板的下表面设有彩膜层，所述下基板的内表面制作有线栅偏光膜和阵列层；所述上下基板内表面制作有取向层，所述对盒内夹有液晶层；所述液晶层周边用封框胶密封；所述下基板的外表面设有纳米颗粒，且纳米颗粒面设有反射板；其中，导光板充当下基板。
(三)有益效果
本发明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若干个容纳光源器件的凹槽，并且在凹槽两个相对的内壁上设有若干个凸起，可最大程度将光源器件的侧面发出的光线加以利用，使得光能利用率提高，进一步实现利用更少的光源器件实现需求亮度，在实现节能的同时可有效地降低对光源器件的散热负担，进而降低模组的内部温度，提供产品的使用寿命；另外，可容纳光源器件的凹槽设置，进一步缩小光源器件的占用面积，可有效实现产品的窄边框。

图3为本发明实施例一背光模组中梯形凸起结构示意图；
图4为本发明实施例光线通过凸起发生反射示意图；
图5为本发明实施例二背光模组中三角形透镜薄膜凸起结构示意图。
具体实施方式
下面结合附图和实施例，对本发明的具体实施方式作进一步详细描述。以下实施例用于说明本发明，但不是用来限制本发明的范围。
实施例一
如图1～4所示，本发明提供一种背光模组，该背光模组，包括：
导光板1以及位于导光板1两侧的PCB基板2，所述PCB基板2上设有若干个光源器件3；
所述导光板1朝向PCB基板2的两侧设有若干个用于容纳光源器件3的凹槽11；凹槽11中两个相对的内壁上设有若干个凸起111。
该凸起111由导光板1制作，其直接形成在凹槽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两侧设置成凹槽结构，可以较好的容纳光源器件，最大程度节省光源器件的占用面积，实现产品的窄边框设置。
另外，更为突出的是，本实施例中的凹槽11中两个相对的内壁上设有若干个凸起111，光源器件发出的光会经过若干个凸起进而发生大规模反射，可最大程度将光源器件的侧面发出的光线加以利用，使得光能利用率提高，进一步实现利用更少的光源器件实现需求亮度，在实现节能的同时可有效地降低对光源器件的散热负担，进而降低模组的内部温度，提供产品的使用寿命。
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。
其中，本发明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可以为连续设置，也可以为间隔设置，该两种设计都能使得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优选为LED灯，当然，除了LED灯，其他光源器件同样适用。
为了将LED灯均被容纳在凹槽中，设置凹槽的数量与LED灯的数量相匹配。
为了保障光源器件发出的光可以较好与凸起发生反射现象，并且较好的将光源器件的热量较快地发散出去，设置光源器件与凹槽内壁之间设有预定距离。
实施例二
如图5所示，本实施例提供的背光模组与实施例一存在的区别在于，该凸起111由透镜薄膜制作，所述透镜薄膜粘贴在凹槽11两个相对的内壁上。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两个相对的内壁上。
同样的，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充当不同形状的凸起，来进一步让光发生更多的反射，提供光的有效使用率。
另一方面，本发明还提供一种显示装置，包括上述的背光模组。该显示装置还包括形成对盒的上基板和下基板，所述上基板的上表面设有上偏光片，其上基板的下表面设有彩膜层，所述下基板的内表面制作有线栅偏光膜和阵列层；所述上下基板内表面制作有取向层，所述对盒内夹有液晶层。所述液晶层周边用封框胶密封；所述下基板的外表面设有纳米颗粒，且纳米颗粒面设有反射板，其中，导光板充当下基板。
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。
本发明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若干个容纳光源器件的凹槽，并且在凹槽两个相对的内壁上设有若干个凸起，可最大程度将光源器件的侧面发出的光线加以利用，使得光能利用率提高，进一步实现利用更少的光源器件实现需求亮度，在实现节能的同时可有效地降低对光源器件的散热负担，进而降低模组的内部温度，提供产品的使用寿命；另外，可容纳光源器件的凹槽设置，进一步缩小光源器件的占用面积，可有效实现产品的窄边框。
以上所述仅是本发明的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本发明技术原理的前提下，还可以做出若干改进和变型，这些改进和变型也应视为本发明的保护范围。
