Transflective
A transflective liquid-crystal display is a liquid-crystal display (LCD) with an optical layer that reflects and transmits light (''transflective'' is a portmanteau of ''transmissive'' and ''reflective''). Under bright illumination (e.g. when exposed to daylight) the display acts mainly as a reflective display with the contrast being constant with illuminance. However, under dim and dark ambient situations the light from a backlight is transmitted through the transflective layer to provide light for the display. The transflective layer is called a transflector. It is typically made from a sheet polymer. It is similar to a one-way mirror but is not specular. An application is digital LCD wristwatches. In dim ambient light or at night a backlight allows reading of the display in its transmissive mode.: W. Boller, M. Donati, J. Fingerle, P. Wild, ''Illuminating Arrangement for a Field-Effect Liquid-Crystal Display as well as Fabrication and Application of the Illuminating Arrangeme ...

Liquid-crystal Display
A liquid-crystal display (LCD) is a flat-panel display or other electronically modulated optical device that uses the light-modulating properties of liquid crystals combined with polarizers. Liquid crystals do not emit light directly but instead use a backlight or reflector to produce images in color or monochrome. LCDs are available to display arbitrary images (as in a general-purpose computer display) or fixed images with low information content, which can be displayed or hidden. For instance: preset words, digits, and seven-segment displays, as in a digital clock, are all good examples of devices with these displays. They use the same basic technology, except that arbitrary images are made from a matrix of small pixels, while other displays have larger elements. LCDs can either be normally on (positive) or off (negative), depending on the polarizer arrangement. For example, a character positive LCD with a backlight will have black lettering on a background that is the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Smartwatch
A smartwatch is a wearable computer in the form of a watch; modern smartwatches provide a local touchscreen interface for daily use, while an associated smartphone app provides management and telemetry, such as long-term biomonitoring. While early models could perform basic tasks, such as calculations, digital time telling, translations, and game-playing, smartwatches released since 2015 have more general functionality closer to smartphones, including mobile apps, a mobile operating system and WiFi/Bluetooth connectivity. Some smartwatches function as portable media players, with FM radio and playback of digital audio and video files via a Bluetooth headset. Some models, called watch phones (or phone watches), have mobile cellular functionality such as making telephone calls. While internal hardware varies, most have an electronic visual display, either backlit LCD or OLED. Some use transflective or electronic paper, to consume less power. They are usually powered by ...

Pebble (watch)
Pebble is a discontinued smartwatch developed by Pebble Technology Corporation. Funding was conducted through a Kickstarter campaign running from April 11, 2012, to May 18, 2012, which raised $10.3 million; it was the most funded project in Kickstarter history, at the time. Pebble began shipping watches to Kickstarter backers in January 2013. Pebble watches can be connected to Android (operating system), Android and iOS devices to show notifications and messages. An online app store distributed Pebble-compatible apps from many developers including ESPN, Uber, Runkeeper, and GoPro. A steel-bodied variant to the original Pebble, the Pebble Steel, was announced at CES 2014 and released in February 2014. It has a thinner body, tactile metal buttons, and a Corning Gorilla Glass screen. It comes in 2 variations: a black matte finish and a brushed stainless steel finish, with both a black leather band and a matching steel band. In 2015, Pebble launched its second generation of smartwat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Watch
A watch is a portable timepiece intended to be carried or worn by a person. It is designed to keep a consistent movement despite the motions caused by the person's activities. A wristwatch is designed to be worn around the wrist, attached by a watch strap or other type of bracelet, including metal bands, leather straps or any other kind of bracelet. A pocket watch is designed for a person to carry in a pocket, often attached to a chain. Watches were developed in the 17th century from spring-powered clocks, which appeared as early as the 14th century. During most of its history the watch was a mechanical device, driven by clockwork, powered by winding a mainspring, and keeping time with an oscillating balance wheel. These are called '' mechanical watches''. In the 1960s the electronic ''quartz watch'' was invented, which was powered by a battery and kept time with a vibrating quartz crystal. By the 1980s the quartz watch had taken over most of the market from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Digital Clock
A digital clock is a type of clock that displays the time digitally (i.e. in numerals or other symbols), as opposed to an analogue clock. Digital clocks are often associated with electronic drives, but the "digital" description refers only to the display, not to the drive mechanism. (Both analogue and digital clocks can be driven either mechanically or electronically, but "clockwork" mechanisms with digital displays are rare). History The first digital pocket watch was the invention of Austrian engineer Josef Pallweber who created his "jump-hour" mechanism in 1883. Instead of a conventional dial, the jump-hour featured two windows in an enamel dial, through which the hours and minutes are visible on rotating discs. The second hand remained conventional. By 1885 Pallweber mechanism was already on the market in pocket watches by Cortébert and IWC; arguably contributing to the subsequent rise and commercial success of IWC. The principles of Pallweber jump-hour movement had ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berlin Hackathon 2012-48
Berlin is the capital and largest city of Germany, both by area and by population. Its more than 3.85 million inhabitants make it the European Union's most populous city, as measured by population within city limits having gained this status after the United Kingdom's, and thus London's, departure from the European Union. Simultaneously, the city is one of the states of Germany, and is the third smallest state in the country in terms of area. Berlin is surrounded by the state of Brandenburg, and Brandenburg's capital Potsdam is nearby. The urban area of Berlin has a population of over 4.5 million and is therefore the most populous urban area in Germany. The Berlin-Brandenburg capital region has around 6.2 million inhabitants and is Germany's second-largest metropolitan region after the Rhine-Ruhr region, and the fifth-biggest metropolitan region by GDP in the European Union. Berlin was built along the banks of the Spree river, which flows into the Havel in the western boro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Anti-reflective Screen
A glossy display is an electronic display with a glossy surface. In certain light environments, glossy displays provide better color intensity and contrast ratios than matte displays. The primary disadvantage of these displays is their tendency to reflect any external light, often resulting in an undesirable glare.Thatcher, Michelle"Counter the glare on your glossy display" '' CNET''. October 23, 2006. Retrieved December 3, 2007. Technology Some LCDs use an antireflective coating, or nanotextured glass surface, to reduce the amount of external light reflecting from the surface without affecting light emanating from the screen as an alternative to matte display."PixelBright LCDs" . '' ScreenTek''. Retrieved December 3, 2007.

Motorola Mobility
Motorola Mobility LLC, marketed as Motorola, is an American consumer electronics manufacturer primarily producing smartphones and other mobile devices running Android. It is a subsidiary of the Chinese multinational technology company Lenovo.;; Motorola Mobility was formed on January 4, 2011, after a split of Motorola into two separate companies, with Motorola Mobility assuming the company's consumer-oriented product lines (including its mobile phone business, as well as its cable modems and pay television set-top boxes), while Motorola Solutions assumed the company's enterprise-oriented product lines. In May 2012 Google acquired Motorola Mobility for US$12.5 billion; the main intent of the purchase was to gain Motorola's patent portfolio, in order to protect other Android vendors from litigation.
