The ability to display graphics and texts on a transparent screen can enable many useful applications. Here we create a transparent display by projecting monochromatic images onto a transparent medium embedded with nanoparticles that selectively scatter light at the projected wavelength. We describe the optimal design of such nanoparticles, and experimentally demonstrate this concept with a blue-color transparent display made of silver nanoparticles in a polymer matrix. This approach has attractive features including simplicity, wide viewing angle, scalability to large sizes and low cost.
在透明屏幕上显示图形和文本的能力可以实现许多有用的应用。在这里，我们通过将单色图像投影到嵌入纳米粒子的透明介质上来创建透明显示器，这些纳米粒子选择性地散射投影波长的光。我们描述了这种纳米粒子的最佳设计，并通过使用聚合物基质中的银纳米粒子制成的蓝色透明显示器实验验证了这一概念。这种方法具有吸引人的特点，包括简单、宽视角、可扩展性和低成本。
