 本发明的最佳实施方式
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。
在图中，结构相似的单元是以相同标号表示。
请参照图2，图2为本发明的透明显示装置的第一优选实施例的结构示意图。本优选实施例的透明显示装置20包括显示模块以及背光模块。显示模块包括液晶显示面板23、偏光板24以及光学薄膜25；液晶显示面板23用于显示画面像素，其包括上下基板以及设置在上下基板之间的液晶层（图中未示出）。偏光板24设置在液晶显示面板23的出光面以及入光面，用于形成相应的偏振光。光学薄膜25设置在液晶显示面板23的出光面上的偏光板24上，用于改善液晶显示面板的显示效果，如增透膜等。

本优选实施例的透明显示装置20使用时，当用户需要查看液晶显示面板23的显示内容时，可以将光源21打开，这样导光板22的第一入光面221接收到光源21的出射光线，并将该出射光线传导至液晶显示面板23，液晶显示面板23可通过该出射光线显示相应的画面内容，满足用户的画面观看需要。
当用户需要查看液晶显示装置20后方物品时，可以将光源21关闭，这样后方物品发出的环境光线通过导光板22的第二入光面222传导至液晶显示面板23，液晶显示面板23可通过该环境光线显示液晶显示装置20后方的物品。
当环境光线入射到导光板22的第二入光面222时，部分环境光线由于入射角度的问题，最终无法从导光板22的出光面射出，从而导致透明显示装置20的透明显示效果较差。而导光板22的第二入光面222上设置有多个凹陷部224，该凹陷部224可以起到聚光的作用，使得更多的环境光线以较小的角度入射到导光板22内部，从而使得更多的环境光线可以从导光板22的出光面223射出，从而提高了透明显示装置20的透明显示效果。

当环境光线入射到光学部件66时，光学部件66上的凹陷部661可以起到聚光的作用，使得更多的环境光线以较小的角度入射到导光板62内部，从而使得更多的环境光线可以从导光板62的出光面623射出，从而提高了透明显示装置60的透明显示效果。同时光学部件66上的凹陷部661的设置不会对光源61的出射光线的发散造成影响，这样即保证了透明显示装置60的透视画面指令，又保证了透明显示装置60的非透视画面的质量。
