随着显示技术的日益发展,各种新型技术不断涌现,透明显示技术因其透明的显示面板这一特性及其独特的应用,越来越受到人们的关注。
透明显示器一般是指可形成透明显示状态以使观看者可看到显示器中显示的影像及显示器背后的景象的显示器。透明显示器具有许多可能的应用,例如建筑物或汽车的窗户和购物商场的展示窗。除了这些大型设备的应用以外,诸如手持式平板电脑的小型设备也可得益于透明显示器,例如,使用户能够观看地图并且能够透过屏幕观看前面的景物。
预期大部分的现有的显示器市场将逐渐地被透明显示器所取代,例如在建筑、广告和公共信息领域。透明显示器分为抬头显示器、透明液晶显示器(Liquid Crystal Display,LCD)与透明有机发光二极管显示器(Organic Light Emitting Display,OLED),在这些透明显示中,抬头显示是采用影像投影的方法实现,而透明液晶显示器与透明OLED显示器属于真正意义上的透明显示。并且相比于LCD显示器,OLED显示器的自身特性使其更加适合制作透明显示器。
