Led Displays for Airports

Led Display Signs for Airports
Our led display signs can also be used for displaying information on large high resolution billboards.

For example arrival and departure information is a high priority data for travelers, we can provide these airports with those large led display screens.

Glossary of Electronic Led Display Characteristics

Ambient Humidity

The humidity of the area or atmosphere around the electronic led display in which it will show no problems and will be working properly without showing malfunctions.

Ambient Temperature

The temperature of the area or atmosphere around the electronic led display (not the operating temperature of the led display itself) in which it will be working properly without showing malfunctions.

Directivity

The property of the led display of being more sensitive in one direction than in another.

Display Area

The area used for displaying the information show on the led display.

DPT

Dynamic Pixel Technology. The display comprises pixels and dots. Pixels are generated dynamically. Dynamic pixels are generated variable from existing dots. By combining adjacent dots, pixels form a dynamically generated logical unit, with adjacent pixels overlapping physically. This will have the effect that the electronic led display flowery color collocated from red, green, blue LED show the actual nature color again.

Electronic LED Display

A numerical readout in which the digit segments are delineated by light emitting diodes.

Frequency of Frame Display

This is the frequency of the cycle which sends the data for one display. The optimum value is determined after taking into consideration flicker and uneven contrast.

Gamma Correction

The correction of tonal ranges in an image, normally by the adjustment of tone curves. Before being displayed, the linear RGB data must be processed (gamma corrected) to compensate for the gamma of the display.

Grey Levels

Scale of grey varieties between the black and the white. Graphical software generally propose 16 or 256 grey levels.

LED - Light Emitting Diode

An electronic device that lights up when electricity is passed through it. LED's are usually red. They are good for displaying images because they can be relatively small, and they do not burn out. However, they require more power than LCD's.

Nominal Work Life

The exact or ideal work life for the electronic led displays.

Pitch

The distance between the center of two adjacent pixels in an array.

Pixel(s)

A pixel is one of the many tiny dots that make up the representation of a picture in a computer's memory. Usually the dots are so small and so numerous that, when displayed on led display panel, they appear to merge into a smooth image. The color and intensity of each dot is chosen individually by the computer to represent a small area of the picture.

Pixel Composition

The number of led's that make up a pixel.

Pixel Pitch

Refers to the distance, typically in inches or millimeters, between pixels from the center of one pixel to the center of an adjacent pixel. The lower the pixel pitch, the sharper the image.

Refresh Frequency

The time needed to display an image. The refresh is measured in Hertz: if the refresh frequency is of 60 Hz, the image is completed on the monitor in 1/60 second. A low refresh frequency (up to 75 Hz) is stressing for our eyes, as we can see the creation of an image and we see it trembling.

Resolution

The number of pixels (individual points of color) contained on a display monitor, expressed in terms of the number of pixels on the horizontal axis and the number on the vertical axis. The sharpness of the image depends on the resolution and the size of the monitor.

RGB

Stands for the colors Red-Green-Blue. These are the primary colors of light, which computers use to display images on a screen. An RGB computer file must be translated into the CMYK (the primary colors of pigment) color space in order to be printed on a printing press.

Viewing Distance

The maximal distance from a point to the led display, where the picture of the led display is still viewable.

Working Area
