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 ar ...

Display Resolution
The display resolution or display modes of a digital television, computer monitor or 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, OLED displays, and similar technologies, and is simply the physical number of columns and rows of pixels cre ...

Yeast Display
Yeast display (or yeast surface display) is a protein engineering technique that uses the expression of recombinant proteins incorporated into the cell wall of yeast for isolating and engineering antibodies. Development The yeast display technique was first published by the laboratory of Professor K. Dane Wittrup and Eric T. Boder. The technology was sold to Abbott Laboratories in 2001. How it works A protein of interest is displayed as a fusion to the Aga2p protein on the surface of yeast. The Aga2p protein is naturally used by yeast to mediate cell–cell contacts during yeast cell mating. As such, display of a protein via Aga2p projects the protein away from the cell surface, minimizing potential interactions with other molecules on the yeast cell wall. The use of magnetic separation and flow cytometry in conjunction with a yeast display library is a highly effective method to isolate high affinity protein ligands against nearly any receptor through directed evolution.

Ribosome Display
Ribosome display is a technique used to perform '' in vitro'' protein evolution to create proteins that can bind to a desired ligand. The process results in translated proteins that are associated with their mRNA progenitor which is used, as a complex, to bind to an immobilized ligand in a selection step. The mRNA-protein hybrids that bind well are then reverse transcribed to cDNA and their sequence amplified via PCR. The result is a nucleotide sequence that can be used to create tightly binding proteins. Ribosome display process Ribosome display begins with a native library of DNA sequences coding for polypeptides. Each sequence is transcribed, and then translated ''in vitro'' into polypeptide. However, the DNA library coding for a particular library of binding proteins is genetically fused to a spacer sequence lacking a stop codon before its end. The lack of a stop codon prevents release factors from binding and triggering the disassembly of the translational complex. So, ...

Phage Display
Phage display is a laboratory technique for the study of protein–protein, protein–peptide, and protein– DNA interactions that uses bacteriophages (viruses that infect bacteria) to connect proteins with the genetic information that encodes them. In this technique, a gene encoding a protein of interest is inserted into a phage coat protein gene, causing the phage to "display" the protein on its outside while containing the gene for the protein on its inside, resulting in a connection between genotype and phenotype. These displaying phages can then be screened against other proteins, peptides or DNA sequences, in order to detect interaction between the displayed protein and those other molecules. In this way, large libraries of proteins can be screened and amplified in a process called ''in vitro'' selection, which is analogous to natural selection. The most common bacteriophages used in phage display are M13 and fd filamentous phage, though T4, T7, and λ phage have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

MRNA Display
mRNA display is a display technique used for ''in vitro'' protein, and/or peptide evolution to create molecules that can bind to a desired target. The process results in translated peptides or proteins that are associated with their mRNA progenitor via a puromycin linkage. The complex then binds to an immobilized target in a selection step (affinity chromatography). The mRNA-protein fusions that bind well are then reverse transcribed to cDNA and their sequence amplified via a polymerase chain reaction. The result is a nucleotide sequence that encodes a peptide with high affinity for the molecule of interest. Puromycin is an analogue of the 3’ end of a tyrosyl-tRNA with a part of its structure mimics a molecule of adenosine, and the other part mimics a molecule of tyrosine. Compared to the cleavable ester bond in a tyrosyl-tRNA, puromycin has a non-hydrolysable amide bond. As a result, puromycin interferes with translation, and causes premature release of translation products. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bacterial Display
Bacterial display (or bacteria display or bacterial surface display) is a protein engineering technique used for in vitro protein evolution. Libraries of polypeptides displayed on the surface of bacteria can be screened using flow cytometry or iterative selection procedures (biopanning). This protein engineering technique allows us to link the function of a protein with the gene that encodes it. Bacterial display can be used to find target proteins with desired properties and can be used to make affinity ligands which are cell-specific. This system can be used in many applications including the creation of novel vaccines, the identification of enzyme substrates and finding the affinity of a ligand for its target protein. Bacterial display is often coupled with magnetic-activated cell sorting (MACS) or fluorescence-activated cell sorting (FACS) techniques. Competing methods for protein evolution ''in vitro'' are phage display, ribosome display, yeast display, and mRNA display. Bacte ...

Display (horse)
Display (1923–1944) was an American Thoroughbred racehorse. Background He was owned and bred by Walter J. Salmon Sr., at his Mereworth Farm near Lexington, Kentucky. Display was sired by U.S. Racing Hall of Fame inductee Fair Play, a descendant of West Australian, the first winner of the English Triple Crown. He was out of the mare Cicuta. Trained by Thomas J. Healey, Display was an extremely difficult horse to handle and in virtually every race caused considerable problems at the starting gate. Nonetheless, he was successful on the racetrack and was always a sound horse that made more than 100 starts in five years of racing. Racing career As a two-year-old, Display was entered in two major races for his age group, but neither was a winning effort. He was a runner-up to the J. K. L. Ross colt Penstick in the 1925 Grey Stakes at Old Woodbine Race Course in Toronto, Ontario, and had a third-place effort in the Pimlico Futurity at Pimlico Race Course in Baltimore, Maryla ...

Display (zoology)
Display behaviour is a set of ritualized behaviours that enable an animal to communicate to other animals (typically of the same species) about specific stimuli. These ritualized behaviours can be visual however many animals depend on a mixture of visual, audio, tactical and/or chemical signals as well. Evolution has tailored these stereotyped behaviours to allow animals to communicate both conspecifically and interspecifically which allows for a broader connection in different niches in an ecosystem. It is connected to sexual selection and survival of the species in various ways. Typically, display behaviour is used for courtship between two animals and to signal to the female that a viable male is ready to mate. In other instances, species may exhibit territorial display behaviour, in order to preserve a foraging or hunting territory for its family or group. A third form is exhibited by tournament species in which males will fight in order to gain the 'right' to breed. Animals ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Trade Show Display
A trade fair, also known as trade show, trade exhibition, or trade exposition, is an exhibition organized so that companies in a specific industry can showcase and demonstrate their latest products and services, meet with industry partners and customers, study activities of rivals, and examine recent market trends and opportunities. In contrast to consumer fairs, only some trade fairs are open to the public, while others can only be attended by company representatives (members of the trade, e.g. professionals) and members of the press, therefore trade shows are classified as either "public" or "trade only". A few fairs are hybrids of the two; one example is the Frankfurt Book Fair, which is trade only for its first three days and open to the general public on its final two days. They are held on a continuing basis in virtually all markets and normally attract companies from around the globe. For example, in the U.S., there are currently over 10,000 trade shows held every year, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Point Of Sale Display
A point-of-sale display (POS display) is a specialised form of sales promotion that is found near, on, or next to a checkout counter (the "point of sale"). They are intended to draw the customers' attention to products, which may be new products, or on special offer, and are also used to promote special events, e.g. seasonal or holiday-time sales. POS displays can include free standing display units (FSDU), shelf edging, dummy packs, strut cards, standees, hanging signs, counter display units (CDU), display packs, endcaps, display stands, mobiles, posters, and banners. POS can also refer to systems used to record transactions between the customer and the commerce. Examples Usually, in smaller retail outlets, POS displays are supplied by the manufacturer of the products, and also sited, restocked and maintained by one of their regular salespersons. This is less common in large supermarkets as they can control the activities of their suppliers due to their large purchasing pow ...

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 a ...
