Gyricon
Gyricon is a type of electronic paper developed at the Xerox PARC Future Concepts division (formerly Palo Alto Research Center, PARC and Xerox PARC) is a research and development company in Palo Alto, California. It was founded in 1969 by Jacob E. "Jack" Goldman, chief scientist of Xerox Corporation, as a div ... (Palo Alto Research Center). It has many of the same properties as paper: it is flexible, contains an image, and is viewable from a wide angle, but it can be erased and written thousands of times. A Gyricon sheet is a thin layer of transparent plastic, in which millions of small beads, somewhat like toner particles, are randomly dispersed. The beads, each contained in an oil-filled cavity, are free to rotate within those cavities. The beads are "bichromal", with hemispheres of two contrasting colors (e.g. black and white, red and white), and charged, so they exhibit an electrical dipole. When voltage is applied to the surface of the sheet, the beads rotate to present ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Electronic Paper
Electronic paper or intelligent paper, is a display device that reflects ambient light, mimicking the appearance of ordinary ink on paper – unlike conventional flat-panel displays which need additional energy to emit their own light. This may make them more comfortable to read, and provide a wider viewing angle than most light-emitting displays. The contrast ratio in electronic displays available as of 2008 approaches newspaper, and newly developed displays are slightly better. An ideal e-paper display can be read in direct sunlight without the image appearing to fade. Technologies include Gyricon, electrophoretics, electrowetting, interferometry, and plasmonics. Many electronic paper technologies hold static text and images indefinitely without electricity. Flexible electronic paper uses plastic substrates and plastic electronics for the display backplane. Applications of e-paper include electronic shelf labels and digital signage, bus station time tables, electronic billboard ...

Xerox PARC
Future Concepts division (formerly Palo Alto Research Center, PARC and Xerox PARC) is a research and development company in Palo Alto, California. It was founded in 1969 by Jacob E. "Jack" Goldman, chief scientist of Xerox Corporation, as a division of Xerox, tasked with creating computer technology-related products and hardware systems. Xerox PARC has been foundational to numerous revolutionary computer developments, including laser printing, Ethernet, the modern personal computer, graphical user interface (GUI) and desktop metaphor–paradigm, object-oriented programming, ubiquitous computing, electronic paper, amorphous silicon (a-Si) applications, the computer mouse, and very-large-scale integration (VLSI) for semiconductors. Unlike Xerox's existing research laboratory in Rochester, New York, which focused on refining and expanding the company's copier business, Goldman's "Advanced Scientific & Systems Laboratory" aimed to pioneer new technologies in advanced physics, mate ...

Bolas De Gyricon
Bolas or bolases (: bola; from Spanish and Portuguese ''bola'', "ball", also known as a ''boleadora'' or ''boleadeira'') is a type of throwing weapon made of weights on the ends of interconnected cords, used to capture animals by entangling their legs. Bolas were most famously used by the gauchos, but have been found in excavations of Pre-Columbian settlements, especially in Patagonia, where indigenous peoples (particularly the Tehuelche) used them to catch 200-pound guanacos and rheas. The Mapuche and the Inca army used them in battle. Mapuche warriors used bolas in their confrontations with the Chilean Army during the Occupation of Araucanía (1861–1883). Use ''Gauchos'' used ''boleadoras'' to capture running cattle or game. Depending on the exact design, the thrower grasps the ''boleadora'' by one of the weights or by the nexus of the cords. The thrower gives the balls momentum by swinging them and then releases the ''boleadora''. The weapon is usually used to ent ...

Display Technology
A display device is an output device for presentation of information in visual or tactile form (the latter used for example in tactile electronic displays for blind people). When the input information that is supplied has an electrical signal the display is called an '' electronic display''. Common applications for ''electronic visual displays'' are television sets or computer monitors. Types of electronic displays In use These are the technologies used to create the various displays in use today. * Liquid-crystal display (LCD) ** Light-emitting diode (LED) backlit LCD ** Thin-film transistor (TFT) LCD ** Quantum dot (QLED) display * Light-emitting diode (LED) display ** OLED display ** AMOLED display ** Super AMOLED display Segment displays Some displays can show only digits or alphanumeric characters. They are called segment displays, because they are composed of several segments that switch on and off to give appearance of desired glyph. The segments are ...

Synthetic Paper
Synthetic paper is a material made out of synthetic resin which is made to have properties similar to regular paper. Synthetic paper is usually made out of either biaxially oriented polypropylene (BOPP) or high-density polyethylene (HDPE). The applications include paper for labels (thus that can bond with ink) and non-label paper. The products can be highly water resistant, flexible, durable and tear resistant. To the polypropylene resin can be added calcium carbonate. The market for synthetic paper includes packaged food and beverage consumption and cosmetics industries.
