An electrophoretic ink for all-printed reflective electronic displays

  title={An electrophoretic ink for all-printed reflective electronic displays},
  author={Barrett O. Comiskey and Jonathan Albert and Hidekazu Yoshizawa and Joseph Jacobson},
It has for many years been an ambition of researchers in display media to create a flexible low-cost system that is the electronic analogue of paper. In this context, microparticle-based displays have long intrigued researchers. Switchable contrast in such displays is achieved by the electromigration of highly scattering or absorbing microparticles (in the size range 0.1–5 μm), quite distinct from the molecular-scale properties that govern the behaviour of the more familiar liquid-crystal… 

Microencapsulated Electrophoretic Films for Electronic Paper Displays

Microencapsulated electrophoretic imaging films have been developed for various display applications. These films exhibit an “ink-on-paper” appearance owing to their strong, near lambertian light

Microcapsule-based materials for electrophoretic displays

Electrophoretic displays, the rewritable non-light-emitting display technology based on the movement of colored pigments inside a low dielectric liquid as a voltage is applied, have attracted a great

Video-speed electronic paper based on electrowetting

It is shown that electrowetting can also be used to form the basis of a reflective display that is significantly faster than electrophoretic displays, so that video content can be displayed.

Jet-Printed Active-Matrix Backplanes and Electrophoretic Displays

The fabrication of large-area electronics, such as active-matrix pixel circuits in flat-panel displays, is becoming increasingly challenging. Particularly for applications such as electronic paper,

The electrophoretic image display (EPID) is a passive display technique based upon the scattering and absorption of ambient light. This paper will review the present status of EPID technology with

Electrophoretic image display (EPID) panel

A new reflective-type electrophoretic image display (EPID) panel is described which is based on electrophoresis. In the EPID panel, a suspension is mainly composed of pigment particles and a

Liquid Crystal Materials for Display Devices

In 1963, Richard Williams observed the formation of very regular patterns or domains in a nematic liquid crystal when the material was subjected to an electric field. This report marked the beginning

Nanofabricated Three Dimensional Photonic Crystals Operating at Optical Wavelengths

We describe the nanofabrication of the first three-dimensional (3-d) photonic crystals with a forbidden photonic bandgap lying in the near infrared region of the electromagnetic spectrum, 1.1 μm < λ

Photonic-bandgap microcavities in optical waveguides

Confinement of light to small volumes has important implications for optical emission properties: it changes the probability of spontaneous emission from atoms, allowing both enhancement and
