于本揭示其中的一实施例中所述透明显示面板1000’还包括盖板17设置于所述阴极层16上。
参照图1、图3以及图5，本揭示还提供一种透明显示面板的显示方法。所述透明显示面板1000”包括有机发光模块100”以及聚合物分散液晶模块200”。所述聚合物分散液晶模块200”包括下基板21以及显示面20。所述有机发光模块100”设置于所述下基板21的另一侧。所述有机发光模块100”包括显示面10。所述有机发光模块100”的所述显示面10与所述聚合物分散液晶模块200”的所述显示面20面向相反的方向。所述显示方法包括下述步骤：
S1：所述有机发光模块100”依一影像讯号点亮或熄灭对应位置的像素P1、P2…；
S2：所述聚合物分散液晶模块200”驱动对应所述有机发光模块100”点亮的所述像素P1位置的聚合物分散液晶23为散射态；以及
S3：所述聚合物分散液晶模块200”驱动对应所述有机发光模块100”熄灭的像素P2位置的所述聚合物分散液晶23为透明态。
具体的，所述有机发光模块100”的每一个像素P1、P2…包含例如，红色R，绿色G，蓝色B三个子像素。但本发明不限于此。
具体的，所述有机发光模块100”的分辨率与所述聚合物分散液晶模块200”的分辨率相同，像素电极位置一一对应。但本揭示不限于此，所述有机发光模块100”的分辨率与所述聚合物分散液晶模块200”的分辨率也可成一比例关系，像素电极位置大致对应或存在对应关系。
具体的，为了能清楚表达光线走向等应用情形，图3绘制的透明显示面板1000”有所省略，仅绘示出下基板21、像素P1、P2、盖板17、聚合物分散液晶材料23、上基板25、以及偏光片26。
参照图4，于本揭示其中的一实施例中所述的透明显示面板的显示方法，当环境光高于一预设亮度时，关闭所述有机发光模块100”，开启所述聚合物分散液晶模块200”进行显示。
具体的，为了能清楚表达光线走向等应用情形，图4绘制的透明显示面板1000”有所省略，仅绘示出下基板21、像素P1、P2、盖板17、聚合物分散液晶材料23、上基板25、以及偏光片26。
参照图3，于本揭示其中的一实施例中所述的透明显示面板的显示方法，当环境光低于一预设亮度时，开启所述有机发光模块100”及所述聚合物分散液晶模块200”进行透明显示。
具体的，所述透明显示面板1000”可以依下方背景光线的强弱进行调节以提高所述有机发光模块100”显示画面的对比度。
由于本揭示的实施例的透明显示面板及透明显示面板的显示方法中，所述有机发光模块设置于所述下基板的另一侧，所述有机发光模块的所述显示面与所述聚合物分散液晶模块的所述显示面面向相反的方向。所述聚合物分散液晶模块驱动对应所述有机发光模块点亮的所述像素位置的聚合物分散液晶为散射态。所述聚合物分散液晶模块驱动对应所述有机发光模块熄灭的所述像素位置的聚合物分散液晶为透明态。因此，本揭示的实施例能在强环境光作为反射式显示，节省功耗。在较暗环境光中实现透明显示，并利用聚合物分散液晶模块调制环境光，提升对比度。
尽管已经相对于一个或多个实现方式示出并描述了本揭示，但是本领域技术人员基于对本说明书和附图的阅读和理解将会想到等价变型和修改。本揭示包括所有这样的修改和变型，并且仅由所附权利要求的范围限制。特别地关于由上述组件执行的各种功能，用于描述这样的组件的术语旨在对应于执行所述组件的指定功能（例如其在功能上是等价的）的任意组件（除非另外指示），即使在结构上与执行本文所示的本说明书的示范性实现方式中的功能的公开结构不等同。此外，尽管本说明书的特定特征已经相对于若干实现方式中的仅一个被公开，但是这种特征可以与如可以对给定或特定应用而言是期望和有利的其他实现方式的一个或多个其他特征组合。而且，就术语“包括”、“具有”、“含有”或其变形被用在具体实施方式或权利要求中而言，这样的术语旨在以与术语“包含”相似的方式包括。
以上仅是本揭示的优选实施方式，应当指出，对于本领域普通技术人员，在不脱离本揭示原理的前提下，还可以做出若干改进和润饰，这些改进和润饰也应视为本揭示的保护范围。
