The basic principle of electronic ink, type and range of applications
With the computer and electronics rapid development of science and technology, information and human cross into the electronic age. Today, electronic, computer and network technology has made printing in the field from pre-press system, printing, finishing the various production processes such as rapid changes have taken place. In technology and equipment, computer typesetting, computer graphics production, Internet publishing and printing, digital printing, electronic books, electronic newspapers are emerging and developed, the materials, electronic paper and electronic ink research and development has begun to market it brought to people is completely different from traditional paper and ink, electronic ink applications for digital printing wings. Electronic technology has undergone a significant role on the print, indicating a rapid development of science and technology will bring us unexpected result. However, in these materials, electronic ink and e-ink concept often gives some confusion, some articles also often called electronic ink electronic ink, in fact, the two are different things.
Electronic ink and electronic paper are interdependent things, it seems two things, in fact are one thing, it always will be described in two par. In short, electronic paper is a thin film, and in the film coated with a layer of charged material, this is the electronic ink. In turn, the electronic ink requires vector, this used to contain electronic ink, electronic paper is. It can also be seen as a thin embedded remote display. Therefore, electronic paper and electronic ink printed on the concept and the traditional paper and ink are different. In the electronic paper and electronic Mexico, with electronic ink, only the so-called electronic paper. The concept of electronic ink can be traced back to 20th century, 70 times, the Xerox's Palo Alto Research Cent re (PARC) researcher Nick Sheridon, to put forward this idea. However, true to glorify the electronic ink, it is Massachusetts Institute of Technology (MIT), Bell Labs, Xerox catch up later, and now two studies in the world. Although there are other companies also studying electronic ink, but technology is mature and the results of products, should continue to MIT, and Xerox to respect.
The basic principle of electronic ink, is the use of electricity is the principle and the negative mutual attraction derived. Although the same principle, but out of MIT, and Xerox cooling of electronic ink, there are some differences. Electronic ink developed by MIT, is the use of the electrophoretic motion principle, this ink is some small silicone capsules in each micro-capsule, filled with a transparent liquid, with a negative electric black particles, and with a positive power of the white particles and the like. Then, use the change in the current campaign with a positive and negative respectively, black and white particles formed graphic. By the MIT, Bell Labs staff established company E-Ink electronic ink is actually some very small resin capsules, these capsules are transparent. In the capsule there is a negative electrode with carbon (black particles), and with the positive electrode of titanium dioxide (white particles). Capsule is coated with film, this piece of transparent film is called before the board, and in the capsule with a layer under the other electrode. If the current through electrodes, carbon and titanium dioxide will be because of electrophoresis theory for vertical motion, and then form a graphic. Those from the black form of carbon dioxide and white illustrations, printed with the text looks very similar. Unlike most electronic paper displays and will be view as the discrepancy, different angles, patterns and text can be read.
The Xerox Corporation is not suspended in the liquid with which the charged particles, they used the capsules is less than 100 microns in diameter of small plastic beads. These small plastic beads of different colors by the two hemispheres, each hemisphere are positively charged or negatively charged. Small plastic beads were placed in small holes in the film, but holes inside, then covered with a transparent liquid, so that plastic bead to rotate. Whenever the current through the electronic paper, the electric field to make glue beads rotate to control what appears in the part of the text or images.
The current e-ink e-paper and the following general types
1. Microcapsule electrophoresis
This is Massachusetts Institute of Technology and E – Ink technology research and development company. The basic principle is transparency in the cell size within the microcapsules, such as dark blue dye into the liquid and the light charged particles, this micro-capsules with a bonding agent to connect to the film with a transparent electrode.
