具体实施方式
下面结合附图和实施例对本发明作进一步详细说明。
如图1和图2所示，本发明实施例1的一种双面显示器，包括背光模组1、第一显示面板2以及第二显示面板3，所述背光模组1包括导光板11、设于导光板11一侧边上的LED光源12、设于导光板11远离LED光源12的另一侧边上的反射镜13、设于导光板11与LED光源12垂直的两侧边上的反射板14；所述反光镜13与LED光源12平行，导光板11远离LED光源12的一侧边与反射镜13的中心相对，第一显示面板2、第二显示面板3分别对称设置在导光板11的两侧表面上，导光板11的两侧表面均设有网点，第一显示面板2以及第二显示面板3与LED光源12相同的一侧通过底座4相互连接，第一显示面板2以及第二显示面板3远离LED光源12的一侧和反射镜13上与LED光源12平行的两侧边连接，使第一显示面板2、第二显示面板3和导光板11上与LED光源12相同的一侧之间形成夹角；反射板14的反光面与导光板11和LED光源12垂直的两侧边相对设置。在本实施例1中，导光板11远离LED光源12的一侧边与反射镜13的中心固定连接。
在本实施例中，反射镜13为曲面反射镜，第一显示面板2、第二显示面板3与LED光源12相同的一侧和底座4与LED光源12相对的一侧连接固定。
实施例1与现有的双面显示器相比，在双面显示器挂于较高处时，也能够保证观看效果不受影响，而且现有的双面显示的显示面板与背光模组的导光板平行，这样只有在垂直于显示面板观看时，才能够获得最佳的观看效果，当双面显示器挂于高处时，由于观看角度的问题，导致观看效果不佳，而实施例1中两块显示面板于导光板之间形成一定的夹角，而且共用一组背光模组，不仅能够提高观看效果，而且还具有降低生产成本。
为了保证远光测不会出现严重的暗区，因此，反射板14为漫反射板，高斯角为20度，这样能够避免补光不均，从而减少暗边的影响。
实施例1中的双面显示器由于显示面板与导光板之间的夹角为固定的，因此无法能够满足不同悬挂高度的场所使用，为了解决这一问题，进一步地，如图2所示，实施例2与实施例1的区别在于显示面板与导光板之间的夹角可调 节，同时保证在夹角增大时不会有暗边产生，具体结构如下：
如图3、图4所示，实施例2的双面显示器，包括背光模组1(图2所示)、第一显示面板2以及第二显示面板3，所述背光模组1包括导光板11、设于导光板11一侧边上的LED光源12、设于导光板11远离LED光源12的另一侧边上的反射镜13、设于导光板11与LED光源12垂直的两侧边上的反射板14；所述反光镜13与LED光源12平行，导光板11远离LED光源12的一侧边与反射镜13的中心相对，第一显示面板2、第二显示面板3分别对称设置在导光板11的两侧表面上，导光板11的两侧表面均设有网点，第一显示面板2以及第二显示面板3与LED光源12相同的一侧通过底座4相互连接，第一显示面板2以及第二显示面板3远离LED光源12的一侧和反射镜13上与LED光源12平行的两侧边连接，使第一显示面板2、第二显示面板3和导光板11上与LED光源12相同的一侧之间形成夹角；反射板14的反光面与导光板11和LED光源12垂直的两侧边相对设置；
所述反射镜13包括第一子反射镜131、第二子反射镜132，所述第一子反射镜131与第二子反射镜132的曲率相等，第二子反射镜132的尺寸小于第一子反射镜131的尺寸，第一子反射镜131与第二子反射镜132并排设置，所述第一显示面板2远离LED光源12的一侧与第一子反射镜131远离第二子反射镜132的一侧连接，第二显示面板3远离LED光源12的一侧与第二子反射镜131远离第一子反射镜131的一侧连接，这样的结构能够满足高度较高的场所使用。
作为实施例2的一种较佳的实施方式，第一反射镜131的内部设有中空的腔体1311，在第一子反射镜131与第二子反射镜132相对的一侧侧边上设有供第二子反射镜132插入并且与腔体1311连通的插入口1312，所述第二子反射镜1312可活动地沿腔体1311来回移动，形成伸缩结构，从而实现可根据不同场所对第一显示面板2和第三显示面板3与导光板11之间的夹角自由调节；为了配合反射镜13的伸缩结果，反射板14包括第一子反射板141和第二子反射板142，所述第一子反射板141叠合在第二子反射板142上，当第二子反射镜131从腔体1311中拉出时，为展开状态，第一子反射板141和第二子反射板142分别朝相反的一侧移动，从而配合反射镜13的伸展；当第二子反射镜132推入腔体1311中时，为收缩状态，此时第一子反射板141和第二子反射板 142朝相对的一侧移动，从而配合反射镜13的收缩(图6所示)；
所述第一显示面板2、第二显示面板3与LED光源12相同的一侧和底座4与LED光源12相对的一侧连接，且可围绕底座4旋转，具体为与底座4铰接，从而实现夹角可调节；相应地，第一显示面板2、第二显示面板3远离LED光源12的一侧与子一子反射镜131、第二子反射镜132之间铰接。
如图5所示，第二子反射板142上与第一子反射板141相对的一侧表面位于反射镜13的边缘处设有滑槽143，所述第一子反射板141与反光镜13相对的一侧插入滑槽143中，从而实现两块子反射板之间的固定，而两块子反射板与底座4相对的一侧则通过转动轴固定在底座4上，从而实现可沿底座4转动。
所述第一子反射板141与第一显示面板2相对的一侧与第一显示面板2的边缘固定，第二子反射板142与第二显示面板3相对的一侧与第二显示面板3的边缘固定，由于固定方式可采用多种形式，在此不做具体限定。
本发明中导光板11的两侧表面上均设有网点，两侧表面的亮度均齐度均在75％以上这样也能够保证无明显暗边的问题。
本发明中第一显示面板2和第二显示面板3与导光板11之间的夹角在增大过程中，除远光侧(导光板远离LDE光源12的一侧)外，左右两侧边(导光板11与LED光源12垂直的两侧边)同样会出现光损失，从而形成暗带。不同的是，左右侧边暗带并非均匀，由近光侧(导光板与LED光源12相对的一侧)向远光侧暗带逐渐增大，故反射参数设置上为避免补光不均，反光板采用漫反射板，反射率约75％，高斯角约20°，这样能够使观看的效果最佳。
实施例2中反射镜13的伸缩结构上可采用抽拉式滑轨来实现折叠功能。将滑轨与显示面板固定在一起，以便张角变化时反射镜面积随之变化，达到最佳反射效果。以远光侧为例，反射装置由两块相同曲率不同尺寸的反射镜组成，尺寸较大反射镜设计成内部中空，在模组张角变小过程中，小反射镜进入大镜内部，实现折叠功能，节省空间，经济时尚。
如图7所示，本发明实施例2中的双面显示器还可包括一滑轨5，滑轨5呈弧形，滑轨5设于第一显示面板2、第二显示面板3远离LED光源12的一 侧上，第一显示面板2、第二显示面板3远离LED光源12的一侧通过滑套51与滑轨5连接，所述滑套51与第一显示面板2、第二显示面板3远离LED光源12的一侧铰接，使第一显示面板2、第二显示面板3沿滑轨5调节其与导光板11相对的夹角，进而使得第一显示面板11、第二显示面板12之间的相对姿态可调；在滑套51上还可以设有锁止件，用于将滑套51固定在想要的位置处。
具体地，滑轨5可设有两条，反光镜13设于两滑轨5之间，并且分别与对应位置上的滑套51连接固定。
虽然已经参照特定实施例示出并描述了本发明，但是本领域的技术人员将理解：在不脱离由权利要求及其等同物限定的本发明的精神和范围的情况下，可在此进行形式和细节上的各种变化。
