10.2: Towards Video‐rate Microencapsulated Dual‐Particle Electrophoretic Displays

Abstract

Abstract Present electrophoretic image displays (EPIDs) suitable for electronic reader applications have typical response times of several hundred milliseconds. In this paper, we describe a new EPID with significantly faster response. This ink has good bistability, a white state reflectivity of ∼40%, a contrast ratio of 12:1 at saturation, and is capable of being driven with image‐to‐image transition times of 30ms at 15v (CR>7).
