16 bit Technology> Index

Its a technology that allows to elaborate videos without reducing the quality in a perceptible way. After this elaboration (cal Gamma Correction) it is possible to visualize 65.000 colors 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.


Brillance> Index

See Lumen

Candela> Index


Cathod Tube> Index

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.
giant screens and CRT monitors are totally different, both for functioning principle and type of application.

CDM> Index

CDM is the acronim of Candela per Square Meter (cd/m2), the Standard unit of luminance (also cal 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.

Color's Levels> Index

Are the touches that every color can have. In the visualization field are considered the colors 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

Its a measure of reference defined by CIE (International Commission for Illumination) and it is measured in Kelvin degrees (K). The colors temperature needed to get the Pure White is around 6000 K

Contrast Level> Index

Its the difference between the light emitted by the display and the environmental light reflected by the screens surface. Minor is the light reflected, higher is the contrast and therefore the cleanliness and naturalness of the images.

Control PC> Index

It is a PC that manage the maxi-screen, to which is directly linked. It can be instal internally (embedded PC) or within a few meters from the display.

Definition> Index

Its the maxi-screens total number of horizontal and vertical s. 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 assemb).

DVI> Index

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> Index

See Gamma Correction

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 maxi-screen. Gamma correction controls and manages the brightness and cleanliness of the images.

IP Protection> Index

It is the degree of protection against dust and humidity. It is identified as IP acronym of Ingress Protection.

> Index

Is the acronym of Light Emitting Diode. The 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)

Lumen> Index

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 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> Index

Luminance (also cal 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> Index

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 brightness. Candela measures how much light is produced as measured at the light source.
Please also see CDM (candela per aquare meter).

NIT> Index

Please see CDM

Pitch> Index

It the distance between the pixels, expressed in millimetres. It is a fundamental measure as it defines the images quality, the displays minimum viewing distance and besides it affect significantly the final cost of the maxi-screen.

Pixel> Index

It the luminous dot typical of every visualization device. It can be composed by one or more s (in some model the pixel is composed by 36 s)

Plasma Display> Index

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.

Plug & Play> Index

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.

Readeability> Index

Its the maximum distance within the images visualized on the screen are readable, therefore clearly recognizable.

Refresh Rate> Index

The refresh rate identify the number of times that the image is refreshed every second.

Remote PC> Index

It is a second PC linked to the Control PC: it is utilized in every situation in which the position of the screen doesnt 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.

Rental Display> Index

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.

Resolution> Index

Its the number of s mounted on every m2. Obviously higher is the number of s, better is the images quality. It is important to note that smaller is the pitch, higher is the resolution.

RGB> Index

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

SMD> Index

See SMD Top

SMD Top > Index

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, s 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.

Start-up> Index

It is the first time the display is instal and turned on. In this occasion an Euro Displays specialized technician take care that all the links between the modules were carried out properly and proceed switching on the maxi-screen.

Top > Index

See SMD Top

Viewing Angle> Index

A screens 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 angulations in which its brightness is reduced to 3000 NIT. fsdfsafsafa

Virtual Pixel> Index

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 cal pixel interpolation.

Visibility> Index

Its the maximum distance within the screen is able to capture humans eyes attention, even if the images are not perfectly recognizable. The visibility of a maxi-display is usually equal to the double of the readability.
