技术领域
本发明涉及平面显示领域，尤其涉及一种灯条及背光模组。
背景技术
液晶显示装置作为一种常见的显示装置，由于其具有功耗低、体积小、质量轻等特点，因此备受用户的青睐。液晶显示装置通常包括背光模组和显示面板，所述背光模组用于为显示面板提供面光源。背光模组依据光源入射位置的不同分为侧入式背光模组和直下式背光模组两种。直下式背光模组是将光源例如冷阴极荧光灯管(Cold Cathode Fluorescent Lamp,CCFL)或者发光二极管(Light Emitting Diode,LED)设置在液晶面板后方，直接形成面光源以提供给显示面板。侧入式背光模组是将发光二极管灯条(light bar)设置于显示面板后方的背板的边缘处，发光二极管灯条发出的光线经过导光板一侧的入光面进入导光板，经过反射和扩散后从导光板的出光面出射以提供给显示面板。然而，随着用户的液晶显示装置显示的画面质量的要求越来越高，为了提升画面的色彩饱和度，改善背光模组中灯条的色度，就可以提升画面的色彩饱和度。现有技术中，通过在背光模组中设置量子条，以达到改善背光模组中灯条色度的技术效果。然而，量子条的安装需要设置特定的安装组件，传统的安装冷阴极荧光灯管和发光二极管的方式并不适合量子条的安装。

其中，所述第一胶带为双面胶，所述量子管包括侧边，所述第一胶带的一面粘结所述量子管的侧边，所述双面胶的另一面粘结所述电路板。
其中，所述第一胶带的宽度大于所述量子管的侧边的宽度。
其中，所述光源的所述出光面与所述量子管之间设置间隙。

其中，所述灯条还包括第二胶带，所述第二胶带为双面胶，所述第二胶带设置于所述量子管远离所述光源的表面上。

附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付 出创造性劳动的前提下，还可以根据这些附图获得其他的附图。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
请一并参阅图1、图2和图3，图1为本发明一较佳实施方式的灯条的结构示意图；图2为图1中I处的局部放大结构示意图；图3为图1中沿II-II线的剖面结构示意图。所述灯条100包括电路板110、多个光源120、量子管130及第一胶带140。所述电路板110用于产生控制信号，所述光源120设置在所述电路板110上且与所述电路板110电连接，所述光源120在所述控制信号的控制下产生第一光线，自所述光源120发出的第一光线经过所述光源120的出光面出射。所述量子管130邻近所述光源120的出光面设置且所述量子管130通过所述第一胶带140与所述电路板110固定连接，所述量子管130用于将所述光源120出射的第一光线转换为第二光线。
所述电路板110可以为印刷电路板(Printed Circuit Board,PCB)也可以为柔性电路板(Flexible Printed Circuit Board,FPC)。所述电路板110在为所述光源120提供控制信号的同时可以支撑和固定所述光源120。
所述光源120设置在所述电路板110上，优选地，所述光源120沿一条直线设置，且相邻的光源120之间间隔均匀排布，以使得自所述光源120出射的 第一光线在进入所述量子管130时混合得比较均匀。
请一并参阅图4，图4为本发明一较佳实施方式的量子管的结构示意图。在本实施方式中，所述量子管130的截面形状为“U”型。所述量子管130包括两个相对设置的侧边130a。相应地，所述第一胶带140为双面胶，所述双面胶的一面粘结所述量子管130的侧边130a，所述双面胶的另一面粘结所述电路板110。优选地，所述第一胶带的宽度大于所述量子管130的侧边的宽度，以更好地将所述量子管130固定在所述电路板110上。
所谓量子管，是利用玻璃等透明材料将量子点密封从而形成了量子管。通过光源照射量子管，可以激发量子管内部的量子点发出高色度的纯色光线，光源发出的光线与量子管内部被激发的高色度的纯色光线混光，从而生产了高色度的白光。而量子点，是可以被用来转换由发光二极管发射的光线光以生成可见或红外区域中的光。量子点是具有比散装(bulk)激子波尔半径小的的直径的纳米晶体。归因于量子局限效应，量子点的电子态之间的能量差是量子点的组分和物理尺寸二者的函数。因此，可以通过改变量子点的物理尺寸来调谐和调整量子点的光学和光电子学属性。量子点吸收比吸收峰值波长更短的所有波长，并发射更长波长处的光。2nm CdSe量子点在可见光谱的蓝色区域中发射，而10nmCdSe量子点在可见光谱的红色区域中发射。量子点应用到显示技术上，可以借助量子点发出能谱集中、非常纯正的高质量红/绿单色光，完全超越传统发光二极管背光的荧光粉发光特性，实现更佳的成像色彩。因此，量子点显示技术被视为未来高效提高显示色域值的最佳方案，更是全球显示行业新的技术风向标。
可以理解地，虽然在本实施方式中以所述量子管130的截面形状为“U”型为例进行描述，所述量子管130的形状并不局限于为“U”型，在其他实施方式中，所述量子管130的形状也可以为半圆形、三角形或者矩形等形状中的一种。
优选地，所述光源120的所述出光面与所述量子管130之间设置间隙，以使得自所述光源120的出光面出射的光线经过混光之后再入射到所述量子管130。

优选地，所述灯条100还包括第二胶带150，所述第二胶带150为双面胶，所述第二胶带150设置于所述量子管130远离所述光源120的表面上。所述量子管130邻近所述光源120的表面作为所述第一光线入射到所述量子管130的入射面，所述量子管130远离所述光源120的表面为所述量子管130的出光面，则，所述第二胶带150设置于所述量子管130的出光面上。通过将所述第二胶带150设置于所述量子管130远离所述光源120的表面上，可以在所述灯条100应用于背光模组时，通过所述第二胶带150将所述量子管130和所述背光模组中的导光板固定，以防止所述量子管130和所述背光模组中的导光板之间的位移，增加了自所述灯条100出射的第二光线进入到所述背光模组中的导光板的入射率。
所述灯条100还包括多个丝印160，所述丝印160设置在所述电路板110的边缘，且每个丝印160分别对应所述光源120设置，所述丝印160用于防止Hotspot现象。所谓Hotspot现象，即在显示领域，相邻的光源之间的间距较大时靠近显示设备边框画面的如光部位出现明暗相间的现象，即为Hotspot现象。在本实施方式中，所述丝印160为黑色丝印。
本实施方式的灯条100通过第一胶带140将所述量子管130固定在所述电路板110上，可以在固定所述量子管130的同时方便所述量子管130的拆卸，以便在所述灯条100出现问题时返工和重装。
