透明显示屏及其制作方法 技术领域
本发明涉及显示技术领域，尤其涉及一种透明显示屏及其制作方法。
 背景技术
现代科技的进步，大大改变了人们的生活方式。特别是互联网时代，人们的衣食住行发生了翻天覆地的变化。人们可以在网上购物、网上点餐、网上预定酒店、网上预约出租车等等，这些方式的实现，都依靠于先进的显示技术。显示屏作为用户的交互界面，可以为用户提供丰富的显示内容，用户也可以通过输入工具对显示屏的内容进行编辑。
显示屏在我们日常生活中随处可见，其中手机是最典型的代表，显示屏因不同的应用场合，也有着不同的形态。移动类产品，通常尺寸较小、轻薄、外形比较多样；公共显示类电子产品通常尺寸比较大、厚重。随着科技的进步以及人们物质生活水平的提高，人们对显示屏提出了更高的要求。特殊的应用场合对显示屏的要求更加苛刻。目前显示屏的总体发展趋势是轻薄、大尺寸、可折叠、抗摔、高响应速度、高显示品质、超窄边框或无边框。有些应用场合还需用到透明显示屏。
目前，主流的透明显示屏主要分为非自发光透明显示屏和自发光透明显示屏两种。非自发光透明显示屏通常透过率低于20%，而且只有在点亮的情况下才是透明的，不加电的时候显示黑态。自发光透明显示屏在加电或不加电的情况都可以是透明的。但不管是非自发光透明显示屏还是自发光透明显示屏，它们的边框都是不透明的，边框的不透明，极大地影响了透明显示的效果，为了解决上述问题，通常的做法都是将边框用透镜或光学膜片遮挡起来，但并不能实现边框区的透明。
在一些特殊场景，例如应用于汽车挡风玻璃的透明显示屏，要求整个显示屏包括边框区都必须是透明的，否则严重影响驾驶员的视线，出现驾驶盲区，产生安全隐患。
