Description

一种侧入式背光源组件及背光模组 技术领域
本发明涉及显示技术领域，尤其涉及一种侧入式背光源组件及背光模组。
背景技术
在目前常见的白光LED背光中，其发光原理为蓝光LED激发黄色荧光粉，其色域饱和值NTSC(National Television Standards Committee，国家电视标准委员会，是一种电视标准)约在60％～80％之间。
量子点是一种由数十个原子所构成的纳米材料，其三个维度的尺寸都在100纳米以内，不同材料组成大小的量子点，放光波长不同。自1990年代问世以来，这类材料曾被用在发光二极体或单色光源装置上，取代传统的荧光粉，直到2000年以后，科学家才开始探究其运用在显示上的可能性。近年来，量子点作为可解决液晶显示器色彩表现性课题的技术备受关注，并引起企业对量子点显示技术的争夺战。为了提升NTSC值，目前一种技术为蓝光LED激发纳米级的量子点，利用量子效应，可使NTSC达到100％以上，提升面板的显示品质。
目前量子点显示技术的一种是将量子点(QD)封装在量子管内，以对量子点进行保护。而量子管的固定是目前研究的课题，主要是通过量子管固定架对量子管进行固定，然而，量子管的长度往往很长，与之匹配的LED灯条往往较短，多根LED灯条之间需要进行电连接，如果采用导线等方式连接容易导致松脱，也必然会增加接线复杂度，并增大量子管固定架的体积，从而影响背光模组和显示装置的尺寸，因此，如何在保证量子管固定的可靠性的同时降低背光源组件的体积非常重要。
发明内容
鉴于现有技术存在的不足，本发明提供了一种基于量子管的体积小的侧入式背光源组件及背光模组。
为了实现上述的目的，本发明采用了如下的技术方案：
一种侧入式背光源组件，包括量子管固定架、固定在所述量子管固定架内的量子管、多根LED灯条以及连接器，所述LED灯条包括基板和固定在所述基板上的多颗发出蓝光的LED灯珠，所述基板贴合于所述量子管固定架底部，所述LED灯珠容纳于所述量子管固定架内并与所述量子管相对设置，所述连接器与相邻的两根所述LED灯条电连接且固定在所述量子管固定架侧壁。
其中，所述量子管固定架由多个子固定架在其长度方向上拼接而成。
其中，每个所述子固定架包括间隔设置的第一侧板和第二侧板以及连接在所述第一侧板和所述第二侧板之间的间隔条，自所述第一侧板和所述第二侧板的内壁均凸设有限位凸起，所述量子管夹设于所述间隔条和所述限位凸起之间。
其中，所述限位凸起与所述量子管相对的面为弧面。
其中，相邻的两个所述子固定架的所述第二侧板的端部外表面凹陷形成台阶部，所述连接器嵌设于相邻的两个所述台阶部围成的空间内。
其中，所述第二侧板高于所述第一侧板。
其中，所述连接器的焊脚朝向所述LED灯珠一侧，并与相邻的两根所述LED灯条电连接。
其中，所述第二侧板的端部靠近底面的部分开设有供所述焊脚穿过的缺口。
其中，所述的侧入式背光源组件还包括遮光块，至少两根相邻的所述子固定架之间不设置所述连接器，所述遮光块贴付于未设置所述连接器的相邻的所述子固定架之间的拼接处。
本发明的另一目的在于提供一种背光模组，包括导光板和上述侧入式背光源组件，所述侧入式背光源组件的所述量子管设于所述导光板的入光侧。
本发明利用量子管固定架固定量子管，多根LED灯条的基板贴合于量子管固定架底部，使LED灯珠容纳于量子管固定架内并与量子管相对设置，利用固定在量子管固定架侧壁的连接器电连接相邻的两根LED灯条，保证了灯条间接线的可靠性，降低了接线的复杂程度，使得接线更方便，量子管固定架的体积更小，提高了背光源组件及背光模组与相应的显示装置的结构紧凑性。

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。
参阅图1和图2，本发明实施例的侧入式背光源组件包括量子管固定架10、固定在量子管固定架10内的量子管20、多根LED灯条30以及连接器40，LED灯条30包括基板和固定在基板上的多颗发出蓝光的LED灯珠，基板贴合于量子管固定架10底部，LED灯珠容纳于量子管固定架10内并与量子管20相对设置，连接器40与相邻的两根LED灯条30电连接且固定在量子管固定架10侧壁。
结合图3所示，量子管固定架10由多个子固定架11在其长度方向上拼接而成，每个子固定架11包括间隔设置的第一侧板11a和第二侧板11b以及连接在第一侧板11a和第二侧板11b之间的多条间隔设置的间隔条11c，这些间隔条11c连接在子固定架11的底部，将第一侧板11a和第二侧板11b之间的间隔分隔成若干个独立的空间，与第一侧板11a和第二侧板11b形成梯子形状的结构，灯条30的基板贴合在相应的子固定架11的底部，同时，LED灯珠容纳在相应的间隔条11c分隔形成的独立的空间内，量子管20支撑在间隔条11c上表面。
为了更好地对量子管20进行限位，自第一侧板11a和第二侧板11b的内壁均朝中间凸出有限位凸起110，量子管20夹设于间隔条11c和限位凸起110之间。这里，该限位凸起110与量子管20相对的面为弧面，与量子管20的外表面相匹配，用于与量子管20更好地接触，从而增加接触面积以保护量子管20。
结合图4所示，本实施例在相邻的两个子固定架11的第二侧板11b的端部外表面凹陷形成台阶部1，然后将连接器40嵌设在相邻的两个台阶部1围成的凹槽空间内，通过这样的设置，连接器40部分或全部嵌入子固定架11内，使得量子管固定架10的整体宽度最小，侧入式背光源组件的尺寸更加紧凑。
其中，第二侧板11b高于第一侧板11a，限位凸起110分别凸出形成于第一 侧板11a的顶部和第二侧板11b的中间部分，第二侧板11b的高度与连接器40的高度一致。为缩短连接器走线并减小连线占用空间，连接器40的焊脚朝向LED灯珠一侧，并与相邻的两根LED灯条30电连接。进一步地，第二侧板11b的端部靠近底面的部分开设有供连接器40的焊脚穿过的缺口111，可以有效避免焊脚与量子管固定架10之间的干涉，同时也避免了增加子固定架11不必要的高度。
如图5，本实施例的侧入式背光源组件还包括遮光块100，当某些LED灯条30足够长时，两根拼接的子固定架11之间并不设置连接器40，遮光块100贴付在未设置连接器40的相邻的子固定架11之间的拼接处，具体是贴付并完全容纳于相邻的两个台阶部1围成的空间内，可以进一步地降低量子管固定架10的整体宽度。这里，遮光块100采用白色橡胶，该遮光块100的存在可以有效遮挡该处的LED灯条30发出的蓝光，避免影响显示效果。
本发明的侧入式背光源组件可应用于各种背光模组中，只需将该侧入式背光源组件的量子管20正对导光板的入光侧一端即可，利用蓝光LED与量子管20的组合可使NTSC达到100％以上，有效提升面板的显示品质。
本发明利用量子管固定架固定量子管，多根LED灯条的基板贴合于量子管固定架底部，使LED灯珠容纳于量子管固定架内并与量子管相对设置，利用固定在量子管固定架侧壁的连接器电连接相邻的两根LED灯条，保证了灯条间接线的可靠性，降低了接线的复杂程度，使得接线更方便，量子管固定架的体积更小，提高了背光源组件及背光模组与相应的显示装置的结构紧凑性。同时，将连接器设置在量子管固定架拼接的地方，且尽量将连接器的焊脚靠近LED灯珠设置，在量子管固定架的拼接处设置容纳连接器的空间，并在该容纳空间的底部开缺口避位，以避免与连接器的焊脚发生干涉，既保证了拼接结构的量子管固定架的最小成型宽度，也降低了背光模组的厚度。
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。
