Display Techniques
Display may refer to: Technology * Display device, output device for presenting information, including: ** Electronic visual display, output device to present information for visual or tactile reception *** Cathode-ray tube (CRT), that uses an electromagnetically deviated electron beam to scan and stimulate a phosphorescent screen; the earliest and once the dominant type of electronic display, but is very large and heavy for the screen size, and thus completely obsolete at the early 21st century *** Flat-panel display (FPD), video display that is much lighter and thinner than deeper, usually older types **** Liquid-crystal display (LCD), displays that use liquid crystals to form images ***** Liquid crystal display television (LCD TV), color TVs that use an LCD to form images **** Plasma display, that uses small plasma cells that responds to electric fields to generate colored images. **** Light-emitting diode (LED), emitting light when electrically charged, producing electrolum ...

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] |
