Electro-optic modulators based on micro-electromechanical systems have found success as elements for optical projectors, for simplified optical spectrometers, and as reflective-type screens that make use of light interference (Interferometric Modulator Display technology). The latter concept offers an exciting avenue for graphene nanomechanical structures to replace classical micro-electromechanical devices and bring about enhancement in performance, especially switching speed and voltage. In this work we study the optical response of electrically actuated graphene drumheads by means of spectrometric and stroboscopic experiments. The color reproducibility and speed of these membranes in producing the desired electro-optic modulation makes them suitable as pixels for high refresh rate displays. As a proof of concept, we demonstrate a Graphene Interferometric Modulator Display prototype with 5 μm-in-diameter pixels that compose a high resolution image (2500 pixels per inch)-equivalent to a 5″ display of 12K-whose color can be changed at frame rates of at least 400 Hz.

用于干涉式调制器显示器的石墨烯机械像素。

基于微机电系统的电光调制器已成功用作光学投影仪，简化的光谱仪以及利用光干涉的反射型屏幕（干涉式调制器显示技术）。后一个概念为石墨烯纳米机械结构取代经典的微机电设备提供了令人兴奋的途径，并带来了性能的增强，尤其是开关速度和电压的提高。在这项工作中，我们通过光谱学和频闪实验研究了电动石墨烯鼓皮的光学响应。这些膜在产生所需的电光调制中的颜色再现性和速度使其适合用作高刷新率显示器的像素。作为概念证明，
