Optical performance of in‐plane electrophoretic color e‐paper

Abstract

Abstract— Several e‐paper technologies are currently under development with the ultimate goal of replacing printed ink on paper. Here, optical performance measurements on monochrome in‐plane electrophoretic e‐paper devices with unsurpassed brightness, contrast, and viewing‐angle performance are reported. The measurement results are captured in a straightforward optical model that allows extrapolation to full‐color performance. It demonstrates that in‐plane electrophoretic color e‐paper technology has the unique potential to deliver on the high standards required by digital‐signage applications.
