Wafer-thin displays offer great market potential in the area of future advertising and information provision by means of interactive packaging.
Flexible electronic paper uses plastic substrates and plastic electronics for the display backplane. As a result, the display takes on color and brightness similar to that of conventional pigments printed on 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.
One such technology is electrophoretic frontplane, developed by the E Ink Corporation. The pocket document reader will take a little longer. In addition, the technology offers a unique path toward high-brightness full-colour displays, leading to displays that are four times brighter than reflective LCDs and twice as bright as other emerging technologies.
It is coated with a layer of polyimide using a standard spin-coating procedure used in the production of AM-LCD displays.
Ultimately electronic ink will permit almost any surface to become a display, bringing information out of the confines of traditional devices and into the world around us. The Gyricon, a Greek term for rotating image, was to be new display technology for the Alto personal computer; eventually, it became the basis for modern e-paper technology.
When a negative electric field is applied, the white particles move to the top of the microcapsule, causing the area to appear to the viewer as a white dot, while the black particles move to the bottom of the capsule and are thus hidden from view.

The reflectivity and contrast are better or equal to those of other reflective display types and are approaching those of paper. 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.
All of these names describe the exact same thing: The sheet is laminated with transparent plastic for protection, resulting in an overall thickness of 80 micrometers, or twice that of ordinary paper. This results in the availability of two thirds of the display area to reflect light in any desired colour.
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.
The paperless office never happened. How do you see the future of e-paper. Next More Seminar Topics: A mobile phone that used the technology is the Motorola Fone. When a voltage is applied between the electrode and the water, the interfacial tension between the water and the coating changes.
Research found that in just few years this technology could replace paper in many situations and leading us ink a truly paperless world.
The contrast ratio in electronic displays available as of approaches newspaper, and newly developed displays are slightly better. Are you interested in this topic.
I stopped the Gyricon work and eventually invented a new electronic-printing technology based on ionography. An ideal e-paper display can be read in direct sunlight without the image appearing to fade.
At this point, I realized the Alto was not going to be developed by Xerox. Many electronic paper technologies hold static text and images indefinitely without electricity.
The three primary colors red, green and blue can be used as pixels for full color displays. But such displays have to date suffered from short lifetimes and difficulty in manufacture.
Any document over a half page in length was likely to be printed, subsequently read, and discarded within a day. The color is selected with an electrically switched light modulator comprising a microscopic cavity that is switched on and off using driver integrated circuits similar to those used to address liquid crystal displays LCD.
Although many potential applications for e-paper technology exist, one of the more exciting products is the e-paper reader, which may soon replace the age-old newspaper and possibly even certain types of books; some. E-Paper Technology Seminar and PPT with pdf report: E-paper is considered more comfortable to read than conventional displays.
It is used in various fields such as Electronic Book, Electronic Newspaper, Mobile display and Computer monitor.

The terms electronic paper, e-paper describe a range of display technologies which are designed to mimic the appearance of ordinary ink on paper5/5(1). 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.Electronic paper technology ppt
