The Gyricon rotating ball display

Abstract

Abstract— The Gyricon display consists of hemispherical black and white (bichromal) balls contained in individual liquid‐filled cavities and disposed to orient in an electrical field. This bistable reflective light display currently has a diffuse reflectance of more than 18% and a contrast ratio of more than 6:1. The viewing angle approaches that of paper. A new method of fabricating the bichromal balls has enabled practical realization of large‐area high‐quality displays.
