Description

一种高耦光效率的背光单元 技术领域
本发明涉及显示技术领域，尤其涉及一种高耦光效率的背光单元。
背景技术
随着液晶电视向大尺寸、超高清4K分辨率甚至8K分辨率技术的发展，液晶面板的像素单元随之增加，像素尺寸和像素开口率相应减小，液晶面板穿透率也随着降低。
为提高大尺寸液晶面板的穿透率，需要增强背光亮度，对于侧入式液晶面板而言，如果仅仅是单边入光，根本无法摆脱目前LED(Light-Emitting Diode，发光二极管)单灯亮度低和散热效果不佳的限制，再加上大尺寸高清液晶面板穿透率较低，单长边设计的亮度也无法达到设计亮度。因此，现有技术有一种增强背光亮度的方法，具体是导光板的短边和长边一侧同时设置侧入式光源，但此种结构的导光板散热不均，极易受热和吸湿膨胀而引起mura(显示器亮度不均匀,造成各种暗影的现象)，同时，导光板膨胀也会撞坏LED，为避免这些现象产生，设计者们通常通过增大LED与导光板之间的耦光距离来降低出现翘曲的风险和撞灯的风险。然而，由于耦光距离的增加，光进入导光板的耦光效率大大降低，尤其是在要求窄边框设计的机种中，为了避免边缘漏光，通常把耦光区上方会加入反射率低材料来降低漏光的风险，这样耦光效率进一步降低。
发明内容
鉴于现有技术存在的不足，本发明提供了一种散热均匀、高耦光效率的背光单元。
为了实现上述的目的，本发明采用了如下的技术方案：
一种高耦光效率的背光单元，包括导光板、设于所述导光板相邻的两个侧壁旁的第一光源组件和第二光源组件以及散热件，所述散热件同时接触所述第一光源组件的第一基板和所述第二光源组件的第二基板且设于所述导光板底部。
其中，所述第一基板与所述导光板之间、所述第二基板与所述导光板之间均设有间距保持件。
其中，所述间距保持件为弹性件。
其中，所述散热件包括接触所述第一基板的第一部分、接触所述第二基板的第二部分和同时接触所述第一基板和所述第二基板的第三部分，所述第三部分宽度大于所述第一部分和所述第二部分。
其中，所述散热件的背面设有若干条散热槽。
其中，所述散热槽互相平行，且与所述导光板的对角线平行。
其中，所述散热槽在所述第三部分的密度最大。
本发明的背光单元在导光板的相邻的两个侧壁旁设有侧入式光源组件，同时设有对侧入式光源组件散热的散热件，可以有效散发光源组件在工作过程中产生的热量，避免了导光板过热膨胀而改变耦光距离引起mura现象；同时，在导光板与各个光源组件之间还设有间距保持件，可以有效防止导光板过热膨胀而撞坏LED。
附图说明
图1为本发明实施例1的背光单元结构示意图。
图2为本发明实施例1的背光单元的另一方向的结构示意图。
图3为本发明实施例2的背光单元结构示意图。
具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
实施例1
参阅图1和图2，本发明提供了一种高耦光效率的背光单元，包括导光板10、第一光源组件11、第二光源组件12和散热件13，第一光源组件11和第二光源组件12分别设于导光板10相邻的两个侧壁旁，第一光源组件11和第二光源组件12均由基板和LED灯珠组成；散热件13为板状结构，同时接触第一光源组件11的第一基板11a和第二光源组件12的第二基板12a且设于导光板10 底部，用于同时对第一光源组件11和第二光源组件12工作过程中产生的热量进行传导，避免LED灯珠过热而损坏，并能减少散发至导光板10的热量。
为防止特殊情况下如受潮时导光板10发生膨胀，第一基板11a与导光板10之间、第二基板12a与导光板10之间均设有间距保持件14，间距保持件14可以是硅胶、橡胶等弹性件，即使在导光板10膨胀时也能保持第一光源组件11、第二光源组件12中的LED灯珠始终与导光板10保持适当的耦光距离，这样，第一光源组件11、第二光源组件12与导光板10之间的耦光距离可以设置得很小，进一步提高了耦光效率。
另外，散热件13包括接触第一基板11a的第一部分13a、接触第二基板12a的第二部分13b和同时接触第一基板11a和第二基板12a的第三部分13c，本实施例中，第一部分13a和第二部分13b为条状，第三部分13c为连接第一部分13a和第二部分13b的中间过渡部分。由于第三部分13c同时传导来自第一基板11a和第二基板12a的热量，第三部分13c受热相对比较集中，如果设计不当容易引起此处受热集中，温度过高时会引起显示器角落漏光的现象。第三部分13c的宽度大于第一部分13a和第二部分13b。具体地，第一部分13a和第二部分13b相互垂直，第三部分13c为第一部分13a和第二部分13b之间的连接板。
为进一步增强第三部分13c的散热能力，使得各个部位的发热情况一致，使不同部位的LED灯珠温度接近，散热件13的背面还设有若干条散热槽130。本实施例中，若干条散热槽130互相平行，且与导光板10的对角线平行，方便第一基板11a和第二基板12a朝原理导光板10的一侧辐射热量。
实施例2
如图3所示，与实施例1不同的是，本实施例的散热槽130在散热件13的第三部分13c的密度设置为最大，可以使得各个部位的发热情况一致，使不同部位的LED灯珠温度接近，有利于改善背光寿命并提高显示装置长期使用后的背光亮度均匀性问题。
可以理解的是，在其他实施方式中，还可通过在散热件13的第三部分13c背面增加散热鳍片等方式减缓该部位散热集中的问题。
本发明的背光单元在导光板的相邻的两个侧壁旁设有侧入式光源组件，同时设有对侧入式光源组件散热的散热件，可以有效散发光源组件在工作过程中产生的热量，避免了导光板过热膨胀而改变耦光距离引起mura现象；同时，在 导光板与各个光源组件之间还设有间距保持件，可以有效防止导光板过热膨胀而撞坏LED。进一步地，通过合理设计散热件各个部位的散热能力使得热量集中的第三部分散热能力高于其它部位，很好地保证了各个部位的温度一致性，可以有效避免局部膨胀引起的耦光距离改变、耦光效率降低的现象发生。
以上所述仅是本申请的具体实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
