本申请所要解决的是提供一种背光模组和显示装置,改善暗影现象。
为实现上述目的,本申请提供了一种背光模组,包括:

如图2至图4所示,本申请实施例公布了一种背光模组100,包括:
背板110,安装于背板110上的背光源120,位于背板110中央的发光区130以及位于背板110边缘,环绕发光区130设置的暗区140;
背光源120包括第一光源121和第二光源122,第一光源121位于发光区130,第二光源122位于暗区140。
本方案中,通过在背光模组100的暗区140增设光源,相较于图1示例性的背光模组,缩小了直下式背光模组100中心位置处的亮度和角落处的亮度对比差距,补足直下式垂直光源于角落及边缘的不足。
在一实施例中,暗区140包括多条侧边150,第二光源122设置在侧边150。
本方案中,只要背光模组100的任意一侧边150有光源,就可以适量补偿背光源120于角落及边缘不足的问题。
如图2所示,在一实施例中,侧边150包括两条平行且相对设置的第一侧边151和两条平行且相对设置的第二侧边152;第一侧边151与第二侧边152相互垂直;第一侧边151的长度大于第二侧边152的长度;第二光源122设置在第二侧边152。
本方案中,将背光源120设置在背光模组100短的一侧,在能补偿角落光线的同时,并节省背光源120的材料与成本。此处对背光源120材料不做限定,可以为LED灯,或LED灯管,还可以为二级发光管等材料。
如图3所示,在一实施例中,暗区140包括多条侧边150,相邻两个侧边150连接形成角落153,第二光源122设置在角落153。
本方案中,在角落上补增光源,使角落有光源照亮,补偿角落光度不足。
在一实施例中,每个角落都设有至少两个第二光源122。
本方案中,充分利用角落空间,在每个角落可利用的空间内多设一颗光源角落光线就会更亮,每个角落153都有至少两颗光源,更易缩小与中央发光区130亮度的差距。
在一实施例中,背光源120包括反射结构160,反射结构160设置于背板110的角落区域;反射结构160与对应第二光源122相互配合。
本方案中,在第二光源122上追加反射结构160,使第二光源122的反射面,角落亮度得到更大的补偿光度。此处对反射片不做限定,可以贴附反射片形成反射结构,或者三个板表面做镜面处理,也可以达到反射光线的目的。
在一实施例中,反射结构160为锥形反射结构180;
本方案中,反射结构160为锥形,更易聚光;已知反射结构160需要在角落设置,而角落又有第二光源122,锥形可以使角落的的光源聚集,亮度更高,反射面更广,更能补足垂直光源于角落的不足。
如图4所示,在一实施例中,所述背板110包括:对应所述发光区130设置的底板170;对应所述暗区140设置,与底板170不在一个平面,并与底板170的第一侧边151互相连接的第一反射板161和对应所述暗区140设置;与底板170不在一个平面,并底板170的第二侧边152互相连接的第二反射板162;所述第一反射板161、第二反射板162和底板170在相交处形成锥形的所述反射结构160;所述第一光源121设置在所述底板170上;所述第二光源122设置所述第一反射板161、第二反射板162和底板170的交点190上。
本方案中,如图4所示,第一反射板161,第二反射片与底板170相连接形成一个不规则平面的相交面,形成一个锥形反射面,第二光源122设置在即锥形反射面的顶点 处,更易聚光,便于角落的亮度提升,而在锥形顶点反射面也最大,将角落光源最大化的反射,补足直下式背光模组100垂直光源导致的角落暗影。
如图4所示,作为本申请的另一实施例,公开了一种背光模组100,包括,
背板110和背光源120,所述背光源120包括第一光源121和第二光源122,所述背板110包括,位于背板的中心区域的底板170,与所述底板170不在一个平面,并与底板170的第一侧边151互相连接的第一反射板161和与所述底板170不在一个平面,并与底板170的第二侧边152互相连接第二反射板162;
所述第一反射板161、第二反射板162和底板170在相交处形成锥形的反射结构160;所述第一光源121设置在所述底板170上;所述第二光源122设置所述第一反射板161、第二反射板162和底板170的交点190上。
如图5所示,作为本申请的另一实施例,公开了一种显示装置200,包括上述任意一项背光模组100。
本申请的技术方案可以广泛用于各种显示面板,如TN型显示面板(全称为Twisted Nematic,即扭曲向列型面板)、IPS型显示面板(In-Plane Switching,平面转换)、VA型显示面板(Vertical Alignment,垂直配向技术)、MVA型显示面板(Multi-domain Vertical Alignment,多象限垂直配向技术),当然,也可以是其他类型的显示面板,如有机发光显示面板(organic light-emitting diode,简称OLED显示面板),均可适用上述方案。
以上内容是结合具体的实施方式对本申请所作的进一步详细说明,不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说,在不脱离本申请构思的前提下,还可以做出若干简单推演或替换,都应当视为属于本申请的保 护范围。
