技术领域
本发明涉及平面显示领域，尤其涉及一种背光模组及显示装置。

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。

图2为本发明一较佳实施方式的显示装置的结构示意图。
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。
请参阅图1，图1为本发明一较佳实施方式的背光模组的结构示意图。所述背光模组10用于为显示装置中的显示面板提供光源。在本实施方式中，所述背光模组10为侧入光式背光模组。所述背光模组10包括胶框100、光源200、电路板300、导光板400及量子点膜500。所述光源200用于发出第一光线，所述光源200包括第一侧面210、第二侧面220及第一出光面230。所述第一侧面210和所述第二侧面220相对设置，所述第一出光面230分别与所述第一侧面210及所述第二侧面220相交，且所述第一出光面230用于出射第一光线。所述电路板300通过所述第一侧面210支撑所述光源200，并为所述光源200提供电能及控制信号。所述导光板400包括入光面410、底面420及第二出光面430。所述入光面410分别与所述底面420及所述第二出光面430相交，所述底面420与所述第二出光面430相对设置，所述导光板400的入光面410 邻近所述第一出光面230设置，所述第一光线自所述导光板400的入光面410进入所述导光板400，并自所述第二出光面430出射。所述量子点膜500对应所述第二侧面220及所述第二出光面430设置，且所述量子点膜500用于将所述第一光线转换为第二光线。
由于本发明的背光模组10中将所述量子点膜500对应所述光源200的所述第二侧面220及所述第二出光面430设置，从而使得所述量子点膜500的边缘对应所述光源200的所述第二侧面220设置，即便所述量子点膜500的边缘与空气中的氧气或者水蒸汽发生反应而失效，也不影响所述量子点膜500对应所述第二出光面430设置的部分，进一步地不会影响到自所述第二出光面430出射的光线照射到所述量子点膜500之后产生的光线的质量。因此，所述背光模组10具有较好的出光品质，使用所述背光模组10的显示装置具有较好的显示品质。
所述胶框100包括本体110和自所述本体的侧面的中部延伸出来的承载部120，所述承载部120上形成与所述本体110相交的端面121。所述光源200还包括与所述第一出光面230相对设置的光源底面240，所述光源底面240邻近所处承载部120设置。所述量子点膜500覆盖在所述端面121、所述第二侧面220及所述第二出光面430上。
所述背光模组10还包括至少一片光学膜片700，所述光学膜片700设置在所述量子点膜500远离所述导光板400的一侧。优选地，所述光学膜片700对应所述端面121、所述第二侧面220及所述第二出光面430设置。在本实施方式中，所述光学膜片700为增亮膜，所述增亮膜用于改善所述第二光线出射到显示装置中的显示面板的出光效率。所述增亮膜可以为一般棱镜片(normal prism sheet)、多功能棱镜片、micro-lens film与反射型偏光片(reflective polarizer)等。
所述背光模组10还包括遮光件800，所述遮光件800设置在所述光学膜片700上，且对应所述第二侧面220及邻近所述第二侧面220的部分第二出光面430设置。所述遮光件800用于遮蔽所述胶框100和所述光源200。在本实施方式中，所述遮光件800为黑色胶带。
所述背光模组10还包括第一双面胶910和反射片600。所述第一双面胶 910用于粘结所述反射片600与所述导光板400，所述第一双面胶910被所述遮光件800覆盖。所述反射片600邻近所述导光板400的所述底面420设置。自所述光源200发出的第一光线经过所述入光面410进入到所述导光板400中，然而部分第一光线经过所述导光板400的底面420出射出去，若部分第一光线经过所述导光板400的底面420出射出去的话，则经过所述第二出光面430出射的光线就会减少，进而使得所述背光模组10出射到液晶显示装置中显示面板的光线减小，进而影响到所述显示面板的亮度。通过在所述导光板400的所述底面420设置所述反射片600，使得经过所述导光板400的所述底面420出射的光线再经过所述反射片600反射到所述导光板400内，进而经过所述第二出光面430出射光线增多，从而增加了背光模组10出射到液晶显示装置中显示面板的光线，进而提高了所述显示面板的亮度。
所述背光模组10还包括第二双面胶920，所述第二双面胶920用于粘结所述电路板300与所述胶框100，以及粘结所述电路板300与所述导光板400。在本实施方式中，通过所述双面胶920将所述电路板300与所述胶框100粘结固定在一起，以及通过所述第二双面胶920将所述电路板300与所述导光板400粘结固定在一起，从而使得所述电路板300相较于所述胶框100以及所述导光板400之间的相对位置固定，进而使得所述光源200相较于所述导光板400的位置固定，从而避免了所述光源200相较于所述导光板400的位置不固定造成的自所述光源200发出的第一光线入射到所述导光板400的入光率低下。
在本实施方式中，所述光源200为蓝光发光二极管，则所述光源200发出的第一光线为蓝光，所述第一光线用于激发所述量子点膜500产生红绿光，所述光源200发出的为蓝光的第一光线与所述量子点膜500产生的所述红绿光进行混光以产生白色的第二光线。
所谓量子点，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。
相较于现有技术，由于本发明的背光模组10中将所述量子点膜500对应所述光源200的所述第二侧面220及所述第二出光面430设置，从而使得所述量子点膜500的边缘对应所述光源200的所述第二侧面220设置，即便所述量子点膜500的边缘与空气中的氧气或者水蒸汽发生反应而失效，也不影响所述量子点膜500对应所述第二侧面220设置的部分，进一步地不会影响到自所述第二出光面430出射的光线照射到所述量子点膜500之后产生的光线的质量。因此，所述背光模组10具有较好的出光品质，使用所述背光模组10的显示装置具有较好的显示品质。

由于本发明的背光模组10中将所述量子点膜500对应所述光源200的所述第二侧面220及所述第二出光面430设置，从而使得所述量子点膜500的边缘对应所述光源200的所述第二侧面220设置，即便所述量子点膜500的边缘与空气中的氧气或者水蒸汽发生反应而失效，也不影响所述量子点膜500对应所述第二出光面430设置的部分，进一步地不会影响到自所述第二出光面430出射的光线照射到所述量子点膜500之后产生的光线的质量。因此，所述背光模组10具有较好的出光品质，使用所述背光模组10的显示装置具有较好的显示品质。
