Abstract

本发明公开了一种双面显示装置及其导光板与背光源，导光板具有中部的反射部，反射部包括同时朝向上出光面和左入光端面的第一反射面、同时朝向上出光面和右入光端面的第二反射面、同时朝向下出光面和左入光端面的第三反射面、同时朝向下出光面和右入光端面的第四反射面，第一反射面、第二反射面、第三反射面和第四反射面首尾相连围成封闭的结构，且反射部完全覆盖与导光板的厚度方向和宽度方向。由于显示装置中通过导光板两端的光源模组发出的光中的水平分量会被反射面改变传输方向，从而被引导至反射至两侧的显示面板，使得光源模组发出的光线的利用率可以提升至少5％～10％，从而不必再额外提高光源亮度，经济节能，产品竞争力得以大幅提升。

Description

一种双面显示装置及其导光板与背光源
技术领域
本发明涉及显示技术领域，尤其涉及一种双面显示装置及其导光板与背光源。
背景技术
TFT-LCD(Thin Film Transistor Liquid Crystal Display，薄膜晶体管液晶显示器)是当前平板显示的主要技术之一，已经成为了现代IT(Information Technology，信息技术)、视讯产品中重要的显示平台。由于液晶本身并不发光，为进行显示，需要配置BL(back light，背光源)。
目前商用显示中的双面显示技术常用的显示结构如图1所示，为实现双面显示需要两个显示面板1面共用一个背光源，没有反射片等传统背光结构，所以对背光源的亮度和光能利用率有更高的要求。其中，两端的LED(Light Emitting Diode，发光二极管)2发出的光经过导光板3传导，再经过导光板3两侧的光学膜片混光处理，最终形成均匀的面光源，供两侧的显示面板1显示用。
然而，传统双面显示架构中的LED 2发出的光中的水平分量，会经过导光板直接传导至对侧，没办法传输至显示模块供显示使用，造成光能的浪费，间接导致背光源功率的增大，不利于节能和提高背光源的光线利用率。
发明内容
鉴于现有技术存在的不足，本发明提供了一种光线利用率高、节能的双面显示装置及其导光板与背光源。
为了实现上述的目的，本发明采用了如下的技术方案：
一种用于双面显示装置的导光板，包括厚度方向上的上出光面、下出光面和长度方向上的左入光端面、右入光端面，所述导光板还包括设于中部的反射部，所述反射部包括同时朝向所述上出光面和所述左入光端面的第一反射面、同时朝向所述上出光面和所述右入光端面的第二反射面、同时朝向所述下出光面和所述左入光端面的第三反射面、同时朝向所述下出光面和所述右入光端面的第四反射面，所述第一反射面、所述第二反射面、所述第三反射面和所述第四反射面首尾相连围成封闭的结构，且所述反射部完全覆盖与所述导光板的厚度方向和宽度方向。
进一步地，所述第一反射面、所述第二反射面、所述第三反射面和所述第四反射面均为弧面。
进一步地，所述第一反射面、所述第二反射面、所述第三反射面和所述第四反射面均朝所述反射部的中部凹陷。
进一步地，所述第一反射面与所述第二反射面、所述第三反射面与所述第四反射面分别对称设置。
进一步地，所述第一反射面与所述第四反射面对称设置。
进一步地，所述导光板由长度方向上的两块子导光板拼接而成，所述反射部为涂覆于两个所述子导光板端面的反射层。
或者，所述导光板由长度方向上的两块子导光板及两个所述子导光板之间的多面体结构的所述反射部拼接而成。
或者，所述导光板由长度方向上的两块子导光板拼接而成，每个所述子导光板的端面凹陷设置，所述反射部包括分别嵌入一个所述子导光板的凹陷的端面的两个子反射体，每个所述子导光板与相应的所述子反射体组成端面为平面的组合体。
本发明的另一目的在于提供一种用于双面显示装置的背光源，包括上述的导光板及其两端的侧入式光源模组。
本发明的又一目的在于提供一种双面显示装置，包括上述的导光板及其两端的侧入式光源模组和两侧的显示面板。
由于显示装置中通过导光板两端的光源模组发出的光中的水平分量会被反射面改变传输方向，从而被引导至反射至两侧的显示面板，使得光源模组发出的光线的利用率可以提升至少5％～10％，从而不必再额外提高光源亮度，经济节能，产品竞争力得以大幅提升。

具体实施方式
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
需要说明的是，为了更好地对实施例进行描述，本文所使用的表示位置关系的术语“上”、“下”、“左”、“右”是以图4的摆放方式为参照进行说明，而这里，“长度方向”是指沿物体较长的方向，“宽度方向”则是指沿物体较窄的方向，厚度方向则是沿物体的高度方向。
实施例1
参阅图2和图3，本实施例的背光源包括导光板10及其两端的侧入式光源模组20，本实施例的光源模组20以LED光源为例进行说明。导光板10包括厚度方向上的上出光面10a、下出光面10b和长度方向上的左入光端面10c、右入光端面10d，导光板还包括设于中部的反射部(图未标)，反射部包括同时朝向上出光面10a和左入光端面10c的第一反射面S1、同时朝向上出光面10a和右入光端面10d的第二反射面S2、同时朝向下出光面10b和左入光端面10d的第三反射面S3、同时朝向下出光面10b和右入光端面10c的第四反射面S4，第一反射面S1、第二反射面S2、第三反射面S3和第四反射面S4首尾相连围成封闭的结构，且反射部完全覆盖与导光板的厚度方向和宽度方向。
结合图4所示，双面显示装置中，中部的反射部具有与导光板10相同的厚度和宽度，使得两端的光源模组20发出的光不能通过，两端的光源模组20发出的光线经反射部反射后分别朝向两侧的上出光面10a、下出光面10b出射。即左侧的光源模组20照射至反射部上半部的光经第一反射面S1反射后自上出光面10a射出，左侧的光源模组20照射至反射部下半部的光经第四反射面S4反射后自上出光面10b射出，右侧的光源模组20照射至反射部上半部的光经第二反射面S2反射后自上出光面10b射出，右侧的光源模组20照射至反射部下半部的光经第三反射面S3反射后自下出光面10b射出。优选第一反射面S1、第二反射面S2、第三反射面S3和第四反射面S4均为弧面，且第一反射面S1、第二反射面S2、第三反射面S3和第四反射面S4均朝反射部的中部凹陷。当第一反射面S1、第二反射面S2、第三反射面S3和第四反射面S4的截面均为1/4圆弧时，经反射部反射的光线覆盖面积较大，显示面板30接收到的光线均匀性较高。可以理解的是，在其他实施方式中，第一反射面S1、第二反射面S2、第三反射面S3和第四反射面S4可以均为平面，围成菱形截面的反射部，单其反射均匀性比圆弧形反射面稍弱。
作为本实施例的一种实施方式，第一反射面S1与第二反射面S2、第三反射面S3与第四反射面S4分别对称设置，且第一反射面S1与第四反射面S4对称设置。此种方式可以保证上下两侧的显示面板30显示的画面具有相同的画质。
为方便制造和组装，本实施例的反射部为单独的多面体结构，其外表面为反光材料，导光板10由长度方向上的两块子导光板及两个子导光板之间的呈多面体结构的该反射部拼接而成，每块子导光板端面凹陷，由分别朝上下两侧扩张的两个凸起的弧面连接而成，以与多面体的反射部形状一致而保证良好地楔合，保证反光效果。
由于显示装置中通过导光板两端的光源模组发出的光中的水平分量会被反射面改变传输方向，从而被引导至反射至两侧的显示面板，使得光源模组发出的光线的利用率可以提升至少5％～10％，从而不必再额外提高光源亮度，经济节能，产品竞争力得以大幅提升。
实施例2
如图5所示，与实施例1不同的是，本实施例的导光板10由长度方向上的两块子导光板拼接而成，反射部为涂覆于两个子导光板端面的反射层，两块子导光板之间中空或者使用其他材料填充而成，此种结构最大限度地节省了材料，提高了产品的竞争力。
实施例3
如图6所示，与实施例1不同的是，本实施例的导光板由长度方向上的两块子导光板拼接而成，每个子导光板的端面凹陷设置，反射部包括两个子反射体，分别嵌入一个子导光板的凹陷的端面，每个子反射体均包括朝向入光端面的反射面和用于与另一个反射体相互贴合的平面，每个子导光板与相应的子反射体组成端面为平面的组合体，以便与另一个子导光板与相应的子反射体组成的组合体组装成完成的导光板。
以上所述仅是本申请的具体实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本申请的保护范围。
