Description

反射片、背光模组以及显示终端
本申请要求于2018年12月20日提交至中国国家知识产权局、申请号为201822144363.9、发明名称为“反射片、背光模组以及显示终端”的专利申请的优先权。
技术领域
本申请涉及显示技术领域，尤其涉及一种反射片、背光模组以及显示终端。
背景技术
液晶显示器根据背光实现方式分为侧入式和直下式，直下式背光具有成本低、组装简单等优点，被广泛使用。但是传统的直下式设计容易出现四角暗影现象，现有技术方案对四角暗影的消除效果有限。
发明内容
基于此，有必要提供一种反射片、背光模组以及显示终端，能提升角落处的亮度，有效消除暗影现象。
其技术方案如下：
一种反射片，包括反射主板及设置在反射主板外周的反射侧板，所述反射侧板与所述反射主板的侧边缘连接，所述反射侧板的转角处设有呈夹角布置的第一骑缝线与第二骑缝线，所述反射侧板相对于所述反射主板倾斜的状态下，所述第一骑缝线与第二骑缝线之间的反射侧板形成弧形反射面；或者，
所述反射侧板的转角处设有呈夹角布置的第一折线与第二折线，所述反射侧板相对于所述反射主板倾斜的状态下，第一折线与第二折线之间的反射侧板形成为弧形反射面。
上述反射片，使用过程中，反射侧板相对反射主板倾斜，即反射主板叠设在背板上，反射侧板相对反射主板向背板内侧弯折形成倾斜面，同时第一骑缝线与第二骑缝线或者第一折线与第二折线之间的反射侧板对应倾斜形成弧形反射面，这样角落部分的反射片属于圆滑过渡，该弧形反射面与角落处的背光源的距离也可更靠近，背光源发出来的光线可以照亮弧形反射面，提升此区域的亮度值，从而达到消除暗影现象的目的。
在其中一实施例中，所述第一骑缝线与第二骑缝线或者所述第一折线与第二折线的相交点位于反射主板的顶点处。
在其中一实施例中，所述第一骑缝线与第二骑缝线或者所述第一折线与第二折线的夹角为45°-120°。
在其中一实施例中，所述第一骑缝线与第二骑缝线或者所述第一折线与第二折线的夹角为90°。
在其中一实施例中，所述反射侧板与所述反射主板的侧边缘通过第三骑缝线或者第三折线连接。
在其中一实施例中，所述反射侧板上设有断开线，所述反射侧板相对于所述反射主板倾斜的状态下，所述断开线两侧的反射侧板对接拼合。
在其中一实施例中，所述反射侧板的外周设有安装板，所述安装板与所述反射侧板的侧边缘通过第四骑缝线或者第四折线连接。
在其中一实施例中，所述反射侧板为多边形环状，所述反射侧板的每个转角处均设置所述第一骑缝线与第二骑缝线或者第一折线与第二折线。
一种背光模组，包括背板、背光源及所述的反射片，所述背光源及所述反射片设置在所述背板上，所述反射片上开设有透光孔，所述背光源的发光件对应所述透光孔设置。
上述背光模组，通过将反射侧板相对反射主板倾斜，即反射主板叠设在背板上，反射侧板相对反射主板向背板内侧弯折形成倾斜面，同时第一骑缝线与第二骑缝线或者第一折线与第二折线之间的反射侧板对应倾斜形成弧形反射面，这样角落部分的反射片属于圆滑过渡，该弧形反射面与角落处的背光源的距离也可更靠近，背光源的发光件通过透光孔发出来的光线可以照亮弧形反射面，提升此区域的亮度值，从而达到消除暗影现象的目的。
一种显示终端，包括所述的反射片或者包括所述的背光模组。
上述显示终端具有所述反射片或者所述的背光模组的有益效果，角落处的亮度值提升，暗影现象少，整体亮度更均匀。

具体实施方式
为使本申请的目的、技术方案及优点更加清楚明白，以下结合附图及具体实施方式，对本申请进行进一步的详细说明。应当理解的是，此处所描述的具体实施方式仅用以解释本申请，并不限定本申请的保护范围。
参见图1、2、3所示，本申请一实施例提供一种反射片10，包括反射主板110及设置在反射主板110外周的反射侧板120，所述反射侧板120与所述反射主板110的侧边缘连接，所述反射侧板120的转角处设有呈夹角布置的第一骑缝线122与第二骑缝线124，所述反射侧板120相对于所述反射主板110倾斜的状态下，所述第一骑缝线122与第二骑缝线124之间的反射侧板120形成弧形反射面125。
根据使用需求，在其他实施例中，也可以在反射侧板的转角处设置呈夹角布置的第一折线与第二折线，所述反射侧板相对于所述反射主板倾斜的状态下，第一折线与第二折线之间的反射侧板形成为弧形反射面。
使用过程中，反射侧板120相对反射主板110倾斜，即反射主板110叠设在背板20上，反射侧板120相对反射主板110向背板20内侧弯折形成倾斜面，同时第一骑缝线122与第二骑缝线124或者第一折线与第二折线之间的反射侧板120对应倾斜形成弧形反射面125，这样角落部分的反射片10属于圆滑过渡，该弧形反射面125与角落处的背光源30的距离也可更靠近，背光源30发出来的光线可以照亮弧形反射面125，提升此区域的亮度值，从而达到消除暗影现象的目的。
参照图2、3，在其中一实施例中，所述第一骑缝线122与第二骑缝线124或者所述第一折线与第二折线的相交点位于反射主板110的顶点处。即弧形反射面125的顶点与反射主板110的顶点重合，便于反射片10的加工成型，同时便于弧形反射面125的形成。
可选地，所述第一骑缝线122与第二骑缝线124或者所述第一折线与第二折线的夹角为45°-120°。一方面确保弧形反射面125的形成区域，提升角落的亮度，另一方面便于反射片10的装配。在其中一实施例中，所述第一骑缝线122与第二骑缝线 124或者所述第一折线与第二折线的夹角为90°。
参照图2、3，在其中一实施例中，所述反射侧板120与所述反射主板110的侧边缘通过第三骑缝线126或者第三折线连接。如此便于反射片10的装配，装配时，反射侧板120通过第三骑缝线126或者第三折线相对反射主板110倾斜。
参照图2、3，在其中一实施例中，所述反射侧板120的外周设有安装板130，所述安装板130与所述反射侧板120的侧边缘通过第四骑缝线128或者第四折线连接。通过设置安装板130，使反射片10能搭接在背板20的翻折边上，便于反射片10的安装与定位。
如图2所示，在其中一实施例中，所述反射侧板120上设有断开线127，所述反射侧板120相对于所述反射主板110倾斜的状态下，所述断开线127两侧的反射侧板120对接拼合。通过设置断开线127，使反射侧板120断开，且在断开线127末端处，所述反射侧板120设计有一断开口，装配状态下，即使反射侧板120呈倾斜放置时，断开口的一边抵靠在断开口的另一边上，其中，断开口的两边之间的长度是根据转角的实际尺寸而设计。其中，断开线127的设计是为了便于装配过程中消除应力，方便安装；而和断开口的设计，使得装配后所述断开线127两侧的反射侧板120能对接拼合，避免出现间隙，影响对接处的亮度均一性。
参照图1，在其中一实施例中，所述反射侧板120为多边形环状，本实施例中反射片10为矩形，反射主板110为矩形，所述反射侧板120的每个转角处均设置所述第一骑缝线122与第二骑缝线124或者第一折线与第二折线。通过在反射片10的每个转角处均形成弧形反射面125，使每个角落的亮度被提升，避免出现暗影。
参照图3，本申请另一实施例提供一种背光模组，包括背板20、背光源30及所述的反射片10，所述背光源30及所述反射片10设置在所述背板20上，所述反射片10上开设有透光孔，所述背光源30的发光件310对应所述透光孔设置。
本实施例的背光模组，通过将反射侧板120相对反射主板110倾斜，即反射主板110叠设在背板20上，反射侧板120相对反射主板110向背板20内侧弯折形成倾斜面，同时第一骑缝线122与第二骑缝线124或者第一折线与第二折线之间的反射侧板120对应倾斜形成弧形反射面125，这样角落部分的反射片10属于圆滑过渡，该弧形反射面125与角落处的背光源30的距离也可更靠近，背光源30的发光件310通过透光孔发出来的光线可以照亮弧形反射面125，提升此区域的亮度值，从而达到消除暗影现象的目的。在其他实施例中，背光模组还包括叠设在反射片10一侧的扩散片或其他光学膜片，起到调节光线的作用。
参照图1-3，一实施例提供一种显示终端，包括所述的反射片10或者包括所述的 背光模组。本实施例的显示终端具有上述任一实施例所述的反射片10或者上述实施例所述的背光模组的有益效果，角落处的亮度值提升，暗影现象少，整体亮度更均匀。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对实用新型专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
