所述背光模组包括:一胶框100、一反射片200、一导光板300、一光学膜片组、以及一连接件500;其中,所述反射片200包括第一本体201和第二本体202,所述第一本体201和所述第二本体202为一体成型,所述第二本体202位于所述第一本体201侧边,所述第一本体201和所述第二本体202围成一开口向上的空腔;其中,所述导光板300和所述光学膜片组均位于由所述第一本体201和所述第二本体202围成的空腔内。所述反射片200、所述导光板300、以及所述光学膜片组均位于所述胶框100内,所述导光板300设置于所述反射片200的第一本体201上方,所述光学膜片组设置于所述导光板300上方。所述第二本体202通过所述连接件500与所述胶框100的内侧面固定贴合在一起。
在本发明实施例中,所述反射片200的所述第二本体202是由所述第一本体201向所述胶框100内侧面延伸而形成的,并通过所述连接件500与所述胶框100内侧面固定贴合,从而使得所述反射片200紧密贴在所述胶框100上,使得所述反射片200不容易从所述胶框100上脱落下来。
在本发明实施例中,为了使得背光模组的边框变窄,所述连接件500可以为双面胶或者是胶水等其他厚度较薄的材料。为了进一步加强所述胶框100与所述反射片200的贴合强度,所述双面胶可以采用口字型双面胶。
作为本发明一优选实施例,所述光学膜片组具体包括:一扩散片600、下棱镜400、以及上棱镜700,所述扩散片600设置于所述导光板300上方,所述下棱镜400设置于所述扩散片600上方,所述上棱镜700设置于所述下棱镜400上方,其中,所述扩散片600、所述下棱镜400、以及所述上棱镜700均位于由所述第一本体201和所述第二本体202围成的空腔内。所述扩散片600可提高背光光线分布均匀的扩散效果,并可提高光线透过率从而产生高亮度。所述光学膜片组具有提高背光模组光学性能的作用。
作为本发明另一优选实施例,所述背光模组还包括:一发光二极管(图中未标示),所述发光二极管设置于所述导光板300侧边,所述发光二极管为所述导光板300提供光源,所述发光二极管100发出的背光光线依次经过所述导光板300和所述光学膜片组发射出去,所述反射片200用于将所述导光板300和所述光学膜片组侧面漏出的光线反射回去;以提高光的使用效率。
由上可知,本实施例由于将反射片向胶框内侧面延伸,并与所述胶框内侧面通过双面胶固定贴合,从而使得所述反射片紧密贴在所述胶框上,使得所述反射片不容易从所述胶框上脱落下来。因此,即使所述胶框宽度进一步变窄,也能保证所述反射片很好的贴合于所述胶框上,实现背光模组的边框大幅度减薄,既可以满足窄边框设计,同时满足膜片的固定强度, 还提高光线的利用率。
实施例二
请参阅图3,为本发明实施例提供的背光模组的结构示意图;为了便于说明,仅示出了与本发明实施例相关的部分。本实施例二与上述实施例一相似,不同之处在于:
所述反射片200还包括由所述第二本体202向所述胶框100上表面延伸形成的第三本体203,所述第三本体203通过所述连接件500与所述胶框100上表面固定贴合。所述第一本体201、所述第二本体202、以及所述第三本体203均为一体成型。
本发明实施例二中,由于将反射片向胶框内侧面延伸,并与所述胶框内侧面通过双面胶固定贴合,所述反射片还向所述胶框上表面延伸,并与所述胶框上表面通过双面胶固定贴合;从而使得所述反射片像弯钩一样紧密扣在所述胶框上,使得所述反射片不容易从所述胶框上脱落下来。因此,即使所述胶框宽度进一步变窄,也能保证所述反射片很好的贴合于所述胶框上,实现背光模组的边框大幅度减薄,既可以满足窄边框设计,同时满足膜片的固定强度, 还提高光线的利用率。
实施例三
请参阅图4,为本发明实施例提供的背光模组的结构示意图;为了便于说明,仅示出了与本发明实施例相关的部分。本实施例三与上述实施例二相似,不同之处在于:
所述反射片200还包括由第三本体203向所述胶框100外侧面延伸形成的第四本体204,所述第四本体204通过所述连接件500与所述胶框100外侧面固定贴合。所述第一本体201、所述第二本体202、所述第三本体203、以及所述第四本体204均为一体成型。
在本实施例中,所述第二本体202、所述第三本体203、以及所述第四本体204围成一开口向下的半封闭结构,所述胶框100的侧边均位于所述半封闭结构内。
本发明实施例三由于将反射片向胶框内侧面延伸,并与所述胶框内侧面通过双面胶固定贴合,所述反射片还向所述胶框上表面延伸,并与所述胶框上表面通过双面胶固定贴合,所述反射片还向所述胶框外侧面延伸,并与所述胶框外侧面通过双面胶固定贴合;从而使得所述反射片的延伸部像倒弯钩一样紧密扣在所述胶框上,使得所述反射片不容易从所述胶框上脱落下来。因此,即使所述胶框宽度进一步变窄,也能保证所述反射片很好的贴合于所述胶框上,实现背光模组的边框大幅度减薄,既可以满足窄边框设计,同时满足膜片的固定强度, 还提高光线的利用率。
实施例四
请一并参阅图2、图3及图4,本发明实施例还提供了一种显示装置,为了便于说明,仅示出了与本发明实施例相关的部分。所述显示装置包括显示面板及背光模组,所述显示面板相对于所述背光模组来设置。本发明的显示面板可以是诸如TFT-LCD(Thin Film Transistor Liquid Crystal Display,薄膜晶体管液晶显示面板)、AMOLED(Active Matrix Organic Light Emitting Diode,有源矩阵有机发光二极管面板)等显示面板。其中,所述显示面板是由两片透明基板以及被封于基板之间的液晶所构成,显示面板具有多个像素,用于显示影像。
下面详细描述所述背光模组的结构。
所述背光模组包括:一胶框100、一反射片200、一导光板300、一连接件500、一扩散片600、下棱镜400、以及上棱镜700;其中,所述反射片200包括第一本体201和第二本体202,所述第一本体201和所述第二本体202为一体成型,所述第二本体202位于所述第一本体201侧边,所述第一本体201和所述第二本体202围成一开口向上的空腔;其中,所述导光板300、所述扩散片600、所述下棱镜400、以及所述上棱镜700均位于由所述第一本体201和所述第二本体202围成的空腔内。所述反射片200、所述导光板300、所述扩散片600、所述下棱镜400、以及所述上棱镜700均位于所述胶框100内,所述导光板300设置于所述反射片200的所述第一本体201上方,所述扩散片600设置于所述导光板300上方,所述下棱镜400设置于所述扩散片600上方,所述上棱镜700设置于所述下棱镜400上方,所述第二本体202通过所述连接件500与所述胶框的内侧面固定贴合在一起。

更优的,所述反射片200还包括由第三本体203向所述胶框100外侧面延伸形成的第四本体204,所述第四本体204通过所述连接件500与所述胶框100外侧面固定贴合。所述第一本体201、所述第二本体202、所述第三本体203、以及所述第四本体204均为一体成型。在本实施例中,所述第二本体202、所述第三本体203、以及所述第四本体204围成一开口向下的半封闭结构,所述胶框100的侧边均位于所述半封闭结构内。
本发明实施例中,由于将反射片向胶框内侧面延伸,并与所述胶框内侧面通过双面胶固定贴合,所述反射片还向所述胶框上表面延伸,并与所述胶框上表面通过双面胶固定贴合,所述反射片还向所述胶框外侧面延伸,并与所述胶框外侧面通过双面胶固定贴合;从而使得所述反射片的延伸部像倒弯钩一样紧密扣在所述胶框上,使得所述反射片不容易从所述胶框上脱落下来。因此,即使所述胶框宽度进一步变窄,也能保证所述反射片很好的贴合于所述胶框上,实现背光模组的边框大幅度减薄,既可以满足窄边框设计,同时满足膜片的固定强度, 还提高光线的利用率。
在本发明实施例中,为了使得背光模组的边框变窄,所述连接件500可以为双面胶或者是胶水等其他厚度较薄的材料。为了进一步加强所述胶框100与所述反射片200的贴合强度,所述双面胶可以采用口字型双面胶。
作为本发明一优选实施例,所述反射片200还向所述胶框100下表面延伸,并通过所述连接件500与所述胶框100下表面固定贴合。
作为本发明另一优选实施例,所述背光模组还包括:一发光二极管,所述发光二极管设置于所述导光板300侧边,所述发光二极管为所述导光板300提供光源,所述发光二极管100发出的背光光线依次经过所述导光板300、所述扩散片600、所述下棱镜400、以及所述上棱镜700发射出去,所述反射片200用于将所述导光板300、所述扩散片600、所述下棱镜400、以及所述上棱镜700侧面漏出的光线反射回去;以提高光的使用效率。
综上所述,本发明实施例由于将反射片向胶框内侧面延伸,并与所述胶框内侧面通过双面胶固定贴合,所述反射片还向所述胶框上表面延伸,并与所述胶框上表面通过双面胶固定贴合,所述反射片还向所述胶框外侧面延伸,并与所述胶框外侧面通过双面胶固定贴合;从而使得所述反射片的延伸部像倒弯钩一样紧密扣在所述胶框上,使得所述反射片不容易从所述胶框上脱落下来。因此,即使所述胶框宽度进一步变窄,也能保证所述反射片很好的贴合于所述胶框上,实现背光模组的边框大幅度减薄,既可以满足窄边框设计,同时满足膜片的固定强度, 还提高光线的利用率。
