E paper technology

Each sphere is a janus particle composed of negatively charged black plastic on one side and positively charged white plastic on the other each bead is thus a dipole.

Published on Nov 14, Abstract E-paper is a revolutionary material that can be used to make next generation I, electronic displays. It is portable reusable storage and display medium that look like paper but can be repeatedly written one thousands of times. These displays make the beginning of a new area for battery power information applications such as cell phones, pagers, watches and hand-held computers etc.

Two companies are carrying our pioneering works in the field of development of electronic ink and both have developed ingenious methods to produce electronic ink.

One is E-ink, a company based at Cambridge, in U.

Both technologies being developed commercially for electronically configurable paper like displays rely on microscopic beads that change color in response to the charges on nearby electrodes. Like traditional paper, E-paper must be lightweight, flexible, glare free and low cost.

Research found that in just few years this technology could replace paper in many situations and leading us E paper technology a truly paperless world.

Electronic ink is a pioneering invention that combines all the desired features of a modern electronic display and the sheer convenience and physical versatility of sheet of paper. E-paper or electronic paper is sometimes called radio paper or smart paper. Paper would be perfect except for one obvious thing: The technology has been identified and developed is well under way.

What exactly is electronic paper?

Within five years, it is envisioned electronic books that can display volumes of information as easily as flipping a page and permanent newspapers that update themselves daily via wireless broadcast. They deliver the readability of paper under b virtually any condition, without backlighting.

And electronic ink displays are persistent without power, drawing current only when they change, which means batteries can be smaller and last E paper technology. The first electronic paper, called Gyricon, consisted of polyethylene spheres between 75 and micrometers across.

Each sphere is a Janus particle composed of negatively charged black plastic on one side and positively charged white plastic on the other each bead is thus a dipole. The spheres are embedded in a transparent silicone sheet, with each sphere suspended in a bubble of oil so that they can rotate freely.

The polarity of the voltage applied to each pair of electrodes then determines whether the white or black side is face-up, thus giving the pixel a white or black appearance. At the FPD exhibition, Japanese company Soken has demonstrated a wall with electronic wall-paper using this technology Electrophoretic An electrophoretic display forms visible images by rearranging charged pigment particles using an applied electric field.

In the simplest implementation of an electrophoretic display, titanium dioxide particles approximately one micrometer in diameter are dispersed in a hydrocarbon oil.

A dark-colored dye is also added to the oil, along with surfactants and charging agents that cause the particles to take on an electric charge.

This mixture is placed between two parallel, conductive plates separated by a gap of 10 to micrometers. When a voltage is applied across the two plates, the particles will migrate electrophoretically to the plate bearing the opposite charge from that on the particles.

When the particles are located at the front viewing side of the display, it appears white, because light is scattered back to the viewer by the high- index titanium particles.

When the particles are located at the rear side of the display, it appears dark, because the incident light is absorbed by the colored dye. If the rear electrode is divided into a number of small picture elements pixelsthen an image can be formed by applying the appropriate voltage to each region of the display to create a pattern of reflecting and absorbing regions.

Electrophoretic displays are considered prime examples of the electronic paper category, because of their paper- like appearance and low power consumption. It is coated with a layer of polyimide using a standard spin-coating procedure used in the production of AM-LCD displays.

This polymide coating can now have a regular TFT matrix formed on top of it in a standard TFT processing plant to form the plastic display, which can then be removed using a laser to finish the display and the glass reused thus lowering the total cost of manufacture. Development in Electrophoretic Display: In the s another type of electronic paper was invented by Joseph Jacobson, who later co- founded the E Ink Corporation which formed a partnership with Philips Components two years later to develop and market the technology.

InPhilips sold the electronic paper business as well as its related patents to Prime View International.

Electronic paper explained: what is it and how does it work?

This used tiny microcapsules filled with electrically charged white particles suspended in colored oil. In early versions, the underlying circuitry controlled whether the white particles were at the top of the capsule so it looked white to the viewer or at the bottom of the capsule so the viewer saw the color of the oil.

Electronic paper goes by many names: e-paper, sometimes spelled as ePaper, electronic ink and (generically, after the company that manufactures it) also e ink. All of these names describe the exact same thing: a technology that mimics the appearance of ordinary ink on paper.

This was essentially a reintroduction of the wellknown electrophoretic display technology, but the use of microcapsules allowed the display to be used on flexible plastic sheets instead of glass. One early version of electronic paper consists of a sheet of very small transparent capsules, each about 40 micrometers across.

Each capsule contains an oily solution containing black dye the electronic inkwith numerous white titanium dioxide particles suspended within. The particles are slightly negatively charged, and each one is naturally white.

The microcapsules are held in a layer of liquid polymer, sandwiched between two arrays of electrodes, the upper of which is made transparent.

The two arrays are aligned so that the sheet is divided into pixels, which each pixel corresponding to a pair of electrodes situated either side of the sheet. The sheet is laminated with transparent plastic for protection, resulting in an overall thickness of 80 micrometers, or twice that of ordinary paper.

Applying a negative charge to the surface electrode repels the particles to the bottom of local capsules, forcing the black dye to the surface and giving the pixel a black appearance.Explore E-Paper Technology with Free Download of Seminar Report and PPT in PDF and DOC Format.
