Electrowetting can be used to provide the pixel engine for a reflective display. By contracting a colored oil film electrically, an optical switch with a high reflectivity (>40%) and contrast (<15) is obtained. In addition to the attractive optical properties, the principle exhibits a video‐rate response speed (∼10 ms) and has a clear route toward a high‐brightness color display [1]. Here we additionally show that the display principle is readily scalable to a pixel size of 160 μm.
