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 pixels , then 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.

In , Philips sold the electronic paper business as well as its related patents to Prime View International. 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. 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 ink , with 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.

The network of electrodes is connected to display circuitry, which turns the electronic ink 'on' and 'off' at specific pixels by applying a voltage to specific pairs of electrodes. 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 "text" of the paper was altered by the presence of an electric field, which turned the balls up or down.

Electronic ink is a proprietary material that is processed into a film for integration into electronic displays. Although revolutionary in concept, electronic ink is a straightforward fusion of chemistry, physics and electronics to create this new material.

Block Diagram: The principal components of electronic ink are millions of tiny microcapsules, about the diameter of a human hair. In one incarnation, each microcapsule contains positively charged white particles and negatively charged black particles suspended in a clear fluid. This results in a partly transparent pixel, or, in case a reflective white surface is used under the switchable element, a white pixel.

Because of the small size of the pixel, the user only experiences the average reflection, which means that a highbrightness, high-contrast switchable element is obtained, which forms the basis of the reflective display.

Displays based on electrowetting have several attractive features. The switching between white and colored reflection is fast enough to display video content. It is a low-power and low-voltage technology, and displays based on the effect can be made flat and thin. The reflectivity and contrast are better than or equal to those of other reflective display types and are approaching those of paper.

In addition, the technology offers a unique path toward high-brightness full-color displays, leading to displays that are four times brighter than reflective LCDs and twice as bright as other emerging technologies.

Challenges: M. Nasim E-Paper Several companies are simultaneously developing electronic paper and ink. While the technologies used by each company provide many of the same features, each has its own distinct technological advantages. All electronic paper technologies face the following general challenges: A method for encapsulation An ink or active material to fill the encapsulation Electronics to activate the ink Electronic ink can be applied to both flexible and rigid materials.

In the case of flexible displays, the base requires a thin, flexible material tough enough to withstand considerable wear, such as extremely thin plastic. The method of how the inks are encapsulated and then applied to the substrate is what distinguishes each company from each other. These processes are complex and are carefully guarded industry secrets. The manufacture of electronic paper promises to be less complicated and less costly than traditional LCD manufacture.

Other technologies being applied to electronic paper include modifications of liquid crystal displays, electro chromic displays, and the electronic equivalent of an Etch A Sketch at Kyushu University. Applications include e-book readers capable of displaying digital versions of books and e-paper magazines, electronic pricing labels in retail shops, time tables at bus stations electronic billboards, and the mobile phone Motorola FONE F3.

Electronic paper should not be confused with digital paper, which is a pad to create handwritten digital documents with a digital pen. Applications Several companies are simultaneously developing electronic paper and ink.

While it is lightweight and durable, it still lacks good color reproduction. The spheres are embedded in a transparent silicone sheet, with each sphere suspended in a bubble of oil so that they can rotate freely. This mixture is placed between two parallel, conductive plates separated by a gap of 10 to micrometers. This makes the surface appear white at that spot. The first electronic paper, called Gyricon, consisted of tiny, statically charged balls that were black on one side and white on the other. This mixture is placed between two parallel, conductive plates separated by a gap of 10 to micro meters.

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. Electronic ink is not intended to diminish or do away with traditional displays. If the rear electrode is divided into a number of small picture elements pixels , then 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.

One is E-ink, a company based at Cambridge, in U. Reversing the voltage has the opposite effect - the particles are forced from the surface, giving the pixel a white appearance. Nasim E-Paper should not be confused with digital paper, which is a pad to create handwritten digital documents with a digital pen. Like traditional paper, E-paper must be lightweight, flexible, glare free and low cost.

Another possible use is in the distribution of an electronic version of a daily paper. Because of the small size of the pixel, the user only experiences the average reflection, which means that a highbrightness, high-contrast switchable element is obtained, which forms the basis of the reflective display.
