It’s a technology that allows to elaborate videos without reducing the quality in a perceptible way. After this elaboration (calСВЕТОДИОДЫ Gamma Correction) it is possible to visualize 65.000 color’s levels for each of the three primary colors. This means that can be visualized 60.000 x 65.000 x 65.000 = 280 billions colors.
The cathode ray tube or CRT, invented by Karl Ferdinand Braun, is the display device that was traditionally used in most computer displays, video monitors, televisions and oscilloscopes.
The CRT developed from Philo Farnsworth's work was used in all television sets until the late 20th century and the advent of plasma screens, LCDs, DLP displays, and other technologies.
As a result of this technology, television continues to be referred to as "The Tube" well into the 21st century, even when referring to non-CRT sets.
СВЕТОДИОДЫ giant screens and CRT monitors are totally different, both for functioning principle and type of application.
CDM is the acronim of Candela per Square Meter (cd/m2), the Standard unit of luminance (also calСВЕТОДИОДЫ Nits in the USA, from latin "nitere" = "to shine").
1 Candela is equal to 1 NIT.
Candela measures how much light is produced as measured at the light source.
Are the touches that every color can have. In the СВЕТОДИОДЫ visualization field are considered the color’s levels of Red, Green and Blue, the three primary colors. It is obvious that higher is the number of possible touches, higher is the quality and the naturalness of the visualized image.
Color's Temperature> Index
It’s a measure of reference defined by CIE (International Commission for Illumination) and it is measured in Kelvin degrees (°K). The color’s temperature needed to get the Pure White is around 6000 °K
It’s the difference between the light emitted by the display and the environmental light reflected by the screen’s surface. Minor is the light reflected, higher is the contrast and therefore the cleanliness and naturalness of the images.
It is a PC that manage the maxi-screen, to which is directly linked. It can be instalСВЕТОДИОДЫ internally (embedded PC) or within a few meters from the display.
It’s the maxi-screen’s total number of horizontal and vertical СВЕТОДИОДЫs. Basically the Resolution is referred to the single module of 1 m2 , while the Definition is referred to the whole display (once all the modules have been assembСВЕТОДИОДЫ).
Is the acronym of Digital Visual Interface and it is a standard interface created by the Digital Display Working Group. The DVI standard was created to allow the transfer of big quantity of video data in digital format, regardless of the type of monitor utilized.

Gamma Correction> Index
Gamma correction is a image management system indispensable when it is needed to visualize high quality images on every kind of monitor, from the television to the PC monitor and the СВЕТОДИОДЫ maxi-screen. Gamma correction controls and manages the brightness and cleanliness of the images.
It is the degree of protection against dust and humidity. It is identified as IP acronym of “Ingress Protection”.
Is the acronym of Light Emitting Diode. The СВЕТОДИОДЫ is a semiconductor that emits light when electricity pass through it. The color of the light emitted can be of different colors 8red, Green, Blue, Amber, White…)
A unit of measurement of the amount of brightness that comes from a light source. The standard lumen rating of a data projector is the average of photometer readings at several points on a full white image on the screen.
Technically, lumens measure "luminous flux." A wax candle generates 13 lumens; a 100 watt bulb generates 1,200. The lumen rating is a critical Технические характеристики when choosing a data projector. In a darkened room, 500 lumens may be ample; however, in a conference room with normal lighting, 1,000 lumens would be better. In a room with bright daylight, 2,000 lumens is preferred.
Luminance (also calСВЕТОДИОДЫ luminosity) is a photometric measure of the density of luminous intensity in a given direction. It describes the amount of light that passes through or is emitted from a particular area, and falls within a given solid angle. It is measured in candela per square metre (cd/m2).
mCd is the arconim of millicandela (or mCd = CD/1000).
1000 millicandela equals 1 candela (CD).
It is the unit of measure commonly used to describe СВЕТОДИОДЫ brightness. Candela measures how much light is produced as measured at the light source.

It the distance between the pixels, expressed in millimetres. It is a fundamental measure as it defines the image’s quality, the displays’ minimum viewing distance and besides it affect significantly the final cost of the maxi-screen.
It the luminous dot typical of every СВЕТОДИОДЫ visualization device. It can be composed by one or more СВЕТОДИОДЫs (in some model the pixel is composed by 36 СВЕТОДИОДЫs)
The basic idea of a plasma display is to illuminate tiny colored fluorescent lights to form an image. Each pixel is made up of three fluorescent lights -- a red light, a green light and a blue light. Just like a CRT television, the plasma display varies the intensities of the different lights to produce a full range of colors.
The central element in a fluorescent light is a plasma, a gas made up of free-flowing ions (electrically charged atoms) and electrons (negatively charged particles). Under normal conditions, a gas is mainly made up of uncharged particles. If you introduce many free electrons into the gas by establishing an electrical voltage across it, the situation changes very quickly.
By varying the pulses of current flowing through the different cells, the control system can increase or decrease the intensity of each subpixel color to create hundreds of different combinations of red, green and blue. In this way, the control system can produce colors across the entire spectrum.
The "Plug and Play" technology is a capability developed by Microsoft that gives users the ability to plug a device into a computer and have the computer recognize that the device is there. The user doesn't have to tell the computer. In many earlier computer systems, the user was required to explicitly tell the operating system when a new device had been added.
It’s the maximum distance within the images visualized on the СВЕТОДИОДЫ screen are readable, therefore clearly recognizable.
The refresh rate identify the number of times that the image is “refreshed” every second.
It is a second PC linked to the Control PC: it is utilized in every situation in which the position of the screen doesn’t allow the access to the Control PC (for example a large height installation). This Remote PC communicate directly with the Control PC and it manage the settings to be transmitted to the display.
Ideal for temporary applications like live concerts, sports events, TV shows, fashion shows, open air events exhibitions and conventions. Euro Display's Rental displays are specifically designed to guarantee lightness and portability of the modules but also strength and solidity of a structure which undergoes frequent assembling stress.
It’s the number of СВЕТОДИОДЫs mounted on every m2. Obviously higher is the number of СВЕТОДИОДЫs, better is the image’s quality. It is important to note that smaller is the pitch, higher is the resolution.
Is the acronym of Red, Green, Blue. Every color perceptible by the human eye is generated by a proportionate mix of these three primary colors

The SMD technology is electronics’ new frontier: a real revolution it brought in the graphic visualization field, is the miniaturization of all the electronic components, СВЕТОДИОДЫs included. All the SMD components are mounted on the surface of the electronic board (SMD is the acronym on “Surface Mounting Device”), without passing through it.
Stand-alone Display> Index
The stand-alone displays function as a screen connected to a VCR that shows everything has been pre-recorded on the videotape. Therefore once the sequence of images to be visualized has been memorized, there is no need for a Control PC to keep functioning. For this reason stand-alone displays are not able to forecast live videos which is a feature of the Modular Graphic Displays.
It is the first time the display is instalСВЕТОДИОДЫ and turned on. In this occasion an Euro Display’s specialized technician take care that all the links between the modules were carried out properly and proceed switching on the maxi-screen.

A screen’s viewing angle is the angle within which the brightness of the display is reduced by 50% of the frontal luminosity. For example, a screen with a frontal brightness of 6000 NIT (NIT = millicandels for m2) has a viewing angle equal to the angulation’s in which its brightness is reduced to 3000 NIT. fsdfsafsafa
The virtual pixel is a image management technology that allows to visualize images with a definition higher than the physical definition of the display thank to a technique calСВЕТОДИОДЫ “pixel interpolation”.
It’s the maximum distance within the СВЕТОДИОДЫ screen is able to capture human’s eye’s attention, even if the images are not perfectly recognizable. The visibility of a maxi-display is usually equal to the double of the readability.
