Display Device
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 ...

Projection Screen
A projection screen is an installation consisting of a surface and a support structure used for displaying a projected image for the view of an audience. Projection screens may be permanently installed on a wall, as in a movie theater, mounted to or placed in a ceiling using a rollable projection surface that retracts into a casing (these can be motorized or manually operated), painted on a wall, or portable with tripod or floor rising models as in a office, conference room or other non-dedicated viewing space. Another popular type of portable screens are inflatable screens for outdoor movie screening (Outdoor cinema, open-air cinema). Uniformly white or grey screens are used almost exclusively as to avoid any discoloration to the image, while the most desired brightness of the screen depends on a number of variables, such as the low-key lighting, ambient light level and the luminous power of the image source. Flat or curved screens may be used depending on the optics used to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Display Window
A display window, also a shop window (British English) or store window (American English), is a window in a shop displaying items for sale or otherwise designed to attract customers to the store. Usually, the term refers to larger windows in the front façade of the shop. History The first display windows in shops were installed in the late 18th century in London, where levels of conspicuous consumption were growing rapidly. Retailer Francis Place was one of the first to experiment with this new retailing method at his tailoring establishment in Charing Cross, where he fitted the shop-front with large plate glass windows. Although this was condemned by many, he defended his practice in his memoirs, claiming that he "sold from the window more goods...than paid journeymen's wages and the expenses of housekeeping. Display windows at boutiques usually have dressed-up mannequins in them. Window dressing Displaying merchandise in a store window is known as window dressing, which is ...

Display Case
A display case (also called a showcase, display cabinet, shadow box, or vitrine) is a Cabinet (furniture), cabinet with one or often more transparency and translucency, transparent tempered glass (or plastic, normally Poly(methyl methacrylate), acrylic for strength) surfaces, used to display objects for viewing. A display case may appear in an exhibition, museum, Retailing, retail store, restaurant, or house. Often, labels are included with the displayed objects, providing information such as descriptions or prices. In a museum, the displayed cultural artifacts are normally part of the museum's Collection (museum), collection, or are part of a temporary exhibition. In retail or a restaurant, the items are normally being offered for sale. A trophy case is used to display sports trophy, trophies or other awards. Description A display case may be freestanding on the floor, or built-in (usually a custom installation). Built-in displays may be mounted on the wall, may act as Room d ...

Display Advertising
Digital display advertising is online graphic advertising through banners, text, images, video, and audio. The main purpose of digital display advertising is to post company ads on third-party websites. A display ad is usually interactive (i.e. clickable), which allows brands and advertisers to engage deeper with the users. A display ad can also be a companion ad for a non-clickable video ad. According to eMarketer, Facebook and Twitter were set to take 33 percent of display ad spending market share by 2017. Desktop display advertising eclipsed search ad buying in 2014, with mobile ad spending overtaking display in 2015. Overview Digital display advertising is an online form of advertising in which the company's promotional messages appear on third-party sites or search engine results pages such as publishers or social networks. There is an evidence showing that this advertising can increase the number of website page view of a company from most types of customers except fr ...

Display Resolution
The display resolution or display modes of a digital television, computer monitor, or other display device is the number of distinct pixels in each dimension that can be displayed. It can be an ambiguous term especially as the displayed resolution is controlled by different factors in cathode-ray tube (CRT) displays, flat-panel displays (including liquid-crystal displays) and projection displays using fixed picture-element (pixel) arrays. It is usually quoted as ', with the units in pixels: for example, ' means the width is 1024 pixels and the height is 768 pixels. This example would normally be spoken as "ten twenty-four by seven sixty-eight" or "ten twenty-four by seven six eight". One use of the term ''display resolution'' applies to fixed-pixel-array displays such as plasma display panels (PDP), liquid-crystal displays (LCD), Digital Light Processing (DLP) projectors, AMOLED, OLED displays, and similar technologies, and is simply the physical number of columns and rows of pi ...

Display Register
In computer science, a call stack is a stack data structure that stores information about the active subroutines and inline blocks of a computer program. This type of stack is also known as an execution stack, program stack, control stack, run-time stack, or machine stack, and is often shortened to simply the "stack". Although maintenance of the call stack is important for the proper functioning of most software, the details are normally hidden and automatic in high-level programming languages. Many computer instruction sets provide special instructions for manipulating stacks. A call stack is used for several related purposes, but the main reason for having one is to keep track of the point to which each active subroutine should return control when it finishes executing. An active subroutine is one that has been called, but is yet to complete execution, after which control should be handed back to the point of call. Such activations of subroutines may be nested to any level (re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Display List
A display list, also called a command list in Direct3D 12 and a command buffer in Vulkan, is a series of graphics commands or instructions that are run when the list is executed. Systems that make use of display list functionality are called retained mode systems, while systems that do not are as opposed to immediate mode systems. In OpenGL, display lists are useful to redraw the same geometry or apply a set of state changes multiple times. This benefit is also used with Direct3D 12's bundle command lists. In Direct3D 12 and Vulkan, display lists are regularly used for per-frame recording and execution. Origins in vector displays The vector monitors or ''calligraphic displays'' of the 1960s and 1970s used electron beam deflection to draw line segments, points, and sometimes curves directly on a CRT screen. Because the image would immediately fade, it needed to be redrawn many times a second ( storage tube CRTs retained the image until blanked, but they were unsuitable for in ...

Video Card
A graphics card (also called a video card, display card, graphics accelerator, graphics adapter, VGA card/VGA, video adapter, display adapter, or colloquially GPU) is a computer expansion card that generates a feed of graphics output to a display device such as a computer monitor, monitor. Graphics cards are sometimes called ''discrete'' or ''dedicated'' graphics cards to emphasize their distinction to an graphics processing unit#Integrated graphics processing unit, integrated graphics processor on the motherboard or the central processing unit (CPU). A graphics processing unit (GPU) that performs the necessary computations is the main component in a graphics card, but the acronym "GPU" is sometimes also used to refer to the graphics card as a whole erroneously. Most graphics cards are not limited to simple display output. The graphics processing unit can be used for additional processing, which reduces the load from the CPU. Additionally, computing platforms such as OpenCL and C ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Flip-disc Display
The flip-disc display (or flip-dot display) is an electromechanical dot matrix display technology used for large outdoor signs, normally those that will be exposed to direct sunlight. Flip-disc technology has been used for external destination signs on buses and trains across North America, Europe and Australia, as well as for variable-message signs on highways. It has also been used extensively on public information displays.Norman Ball, John Vardalas"Ferranti-Packard" McGill Queen's Press, 1994, A few game shows have also used flip-disc displays, including Canadian shows like ''Just Like Mom'', ''The Joke's on Us'' and ''Uh Oh! (game show), Uh Oh!'', but most notably the American game show ''Family Feud'' from 1976 to 1995, and its British version ''Family Fortunes'' from 1980 to 2002. The Polish version of Family Feud, Familiada, still uses this board, which was bought from the Swedish version of the show. Design The flip-disc display consists of a grid of small metal discs ...

Split-flap Display
A split-flap display, or sometimes simply a flap display, is a digital electromechanical display device that presents changeable alphanumeric text, and occasionally fixed graphics. They were (from the 1960s to 1990s) commonly used as public transport timetables in airports and railway stations. They were often called Solari boards after the Italian display manufacturer Solari di Udine, or, in Central European countries, Pragotron after the Czech manufacturer. Split-flap displays were once commonly used in consumer digital clocks known as flip clocks. Design Each character position or graphic position has a collection of flaps on which characters or graphics are painted or silkscreened. Larger flaps can display whole words, while smaller flaps display individual characters. The flaps are precisely flipped to display the desired character or graphic. These devices typically show departure or arrival information in railway stations and airports, where they serve as flight ...
