E-paper
Electronic paper, also sometimes electronic ink, e-ink or electrophoretic display, are display devices that mimic the appearance of ordinary ink on paper. Unlike conventional flat panel displays that emit light, an electronic paper display reflects ambient light like paper. 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 (2008) developed displays are slightly better. An ideal e-paper display can be read in direct sunlight without the image appearing to fade. 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 electronic visual displays include electronic shelf labels and digital signage, bus station time tables, electronic billboards, smartphone displays, a ...

Barnes & Noble Nook
The Barnes & Noble Nook (styled nook or NOOK) is a brand of e-readers developed by American book retailer Barnes & Noble, based on the Android platform. The original device was announced in the U.S. in October 2009, and was released the next month. The original Nook had a six-inch E-paper display and a separate, smaller color touchscreen that serves as the primary input device and was capable of Wi-Fi and AT&T 3G wireless connectivity. The original Nook was followed in November 2010 by a color LCD device called the Nook Color, in June 2011 by the Nook Simple Touch, and in November 2011 and February 2012 by the Nook Tablet.

In December 2014, B&N purchased Microsoft's Nook shares, ending the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Electronic Shelf Label
An electronic shelf label (ESL) system is used by retailers for displaying product pricing on shelves. The product pricing is automatically updated whenever a price is changed under the control of a central server. Typically, electronic display modules are attached to the front edge of retail shelving. Technological development of electronic shelf labels ESL modules use electronic paper (E-paper) or liquid-crystal display (LCD) to show the current product price to the customer. E-paper is widely used on ESLs as it provides crisp display and supports full graphic imaging while needing no power to retain an image. A communication network allows the price display to be automatically updated whenever a product price is changed. This communication network is the true differentiation and what really makes ESL a viable solution. The wireless communication must support reasonable range, speed, battery life, and reliability. The means of wireless communication can be based on radio, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Reading A Kindle On Public Transit
Reading is the process of taking in the sense or meaning of letters, symbols, etc., especially by sight or touch. For educators and researchers, reading is a multifaceted process involving such areas as word recognition, orthography (spelling), alphabetics, phonics, phonemic awareness, vocabulary, comprehension, fluency, and motivation. Other types of reading and writing, such as pictograms (e.g., a hazard symbol and an emoji), are not based on speech-based writing systems. The common link is the interpretation of symbols to extract the meaning from the visual notations or tactile signals (as in the case of Braille). Overview Reading is typically an individual activity, done silently, although on occasion a person reads out loud for other listeners; or reads aloud for one's own use, for better comprehension. Before the reintroduction of separated text (spaces between words) in the late Middle Ages, the ability to read silently was considered rather remarkable. Majo ...

Kobo EReader
The Kobo eReader is an e-reader produced by Toronto-based Kobo Inc. The company's name is an anagram of "book". The original version was released in May 2010 and was marketed as a minimalist alternative to the more expensive e-book readers available at the time. Like most e-readers, the Kobo uses an electronic ink screen.. The Arc tablet series, released between 2011 and 2013, was based on LCD technology instead. E Ink devices Chronological overview Current Common attributes All Kobo e-readers share a unique pagination system giving users the option to count and reference pages separately within each chapter as opposed to the book as a whole. The latter, however, is user selectable as an alternative. Up until an update in January 2022 Kobo readers required connection to the Internet during the initial setup phase and did not work until they were connected to Kobo's servers. Kobo e-readers support viewing Epub, Adobe PDF, plain text, HTML, and unprotected Mobipo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sony Reader
The Sony Reader was a line of e-book readers manufactured by Sony, who produced the first commercial E Ink e-reader with the Sony Librie in 2004. It used an electronic paper display developed by E Ink Corporation, was viewable in direct sunlight, required no power to maintain a static image, and was usable in portrait or landscape orientation. Sony sold e-books for the Reader from the Sony eBook Library in the US, UK, Japan, Germany, Austria, Canada, France, Italy, and Spain. The Reader also could display Adobe PDFs, ePub format, RSS newsfeeds, JPEGs, and Sony's proprietary BBeB ("BroadBand eBook") format. Some Readers could play MP3 and unencrypted AAC audio files.

Active Matrix
Active matrix is a type of addressing scheme used in flat panel displays. In this method of switching individual elements (pixels), each pixel is attached to a transistor and capacitor ''actively'' maintaining the pixel state while other pixels are being addressed, in contrast with the older passive matrix technology in which each pixel must maintain its state passively, without being driven by circuitry. Active matrix technology was invented by Bernard J. Lechner at RCA, using MOSFETs (metal-oxide-semiconductor field-effect transistors). Active matrix technology was first demonstrated as a feasible device using thin-film transistors (TFTs) by T. Peter Brody, Fang Chen Luo and their team at the Thin-Film Devices department of Westinghouse Electric Corporation in 1974, and the term was introduced into the literature in 1975. Given an ''m'' × ''n'' matrix, the number of connectors needed to address the display is ''m'' + ''n'' (just like in passive matrix techn ...

Thin-film Transistor
A thin-film transistor (TFT) is a special type of field-effect transistor (FET) where the transistor is thin relative to the plane of the device. TFTs are grown on a supporting (but non-conducting) substrate. A common substrate is glass, because the traditional application of TFTs is in liquid-crystal displays (LCDs). This differs from the conventional bulk metal oxide field effect transistor (MOSFET), where the semiconductor material typically ''is'' the substrate, such as a silicon wafer. Design and Manufacture TFTs can be fabricated with a wide variety of semiconductor materials. Because it is naturally abundant and well understood, amorphous or polycrystalline silicon was historically used as the semiconductor layer. However, because of the low mobility of amorphous silicon and the large device-to-device variations found in polycrystalline silicon, other materials have been studied for use in TFTs. These include cadmium selenide, metal oxides such as indium gallium zi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MOSFET
The metal–oxide–semiconductor field-effect transistor (MOSFET, MOS-FET, or MOS FET) is a type of field-effect transistor (FET), most commonly fabricated by the controlled oxidation of silicon. It has an insulated gate, the voltage of which determines the conductivity of the device. This ability to change conductivity with the amount of applied voltage can be used for amplifying or switching electronic signals. A metal-insulator-semiconductor field-effect transistor (MISFET) is a term almost synonymous with MOSFET. Another synonym is IGFET for insulated-gate field-effect transistor. The basic principle of the field-effect transistor was first patented by Julius Edgar Lilienfeld in 1925.Lilienfeld, Julius Edgar (1926-10-08) "Method and apparatus for controlling electric currents" upright=1.6, Two power MOSFETs in V_in_the_''off''_state,_and_can_conduct_a_continuous_current_of_30 surface-mount_packages._Operating_as_switches,_each_of_these_components_can_su ...

Pixel
In digital imaging, a pixel (abbreviated px), pel, or picture element is the smallest addressable element in a raster image, or the smallest point in an all points addressable display device. In most digital display devices, pixels are the smallest element that can be manipulated through software. Each pixel is a sample of an original image; more samples typically provide more accurate representations of the original. The intensity of each pixel is variable. In color imaging systems, a color is typically represented by three or four component intensities such as red, green, and blue, or cyan, magenta, yellow, and black. In some contexts (such as descriptions of camera sensors), ''pixel'' refers to a single scalar element of a multi-component representation (called a ''photosite'' in the camera sensor context, although '' sensel'' is sometimes used), while in yet other contexts (like MRI) it may refer to a set of component intensities for a spatial position.
