LED Signs 101

Light emitting diodes (LED) are special diodes that emit light when illuminated by the movement of electrons in the semi-conductor chips. Thousands of these LED's are placed together on a sign, creating the clear images and pictures that you see.



LED Signs Product Terminology


Pixel
The smallest discrete component of an image or picture.

Pitch
The distance on center between pixels. One of the determining factors in character size and display size.

Pixel Size
The dimension of the pixel both height and width. Assists in determining “Live Area” of the display.

Viewing Angle
The angle within which the light output of an LED is perceived at 100% brightness, outside of this angle the brightness is reduced by half.

Brightness (NITS)
The light output per square meter.


Monochrome LED Signs
Any display utilizing a single color LED that is not capable of controlling individual pixel intensity.

Grey-scale Mono 256 LED Signs
Any display utilizing a single color LED that is capable of controlling individual pixel intensity.

RGB Full Color LED Signs
Any display utilizing Red, Green and Blue LEDs and is capable of controlling each individual color’s intensity within the individual pixel.


Advantages of LED Signs

LED Sign technology is quickly becoming tomorrow's primary light sourceand has several advantages over conventional light sources:

• LED’s for sign illumination are rated for continual use for up to 100,000 hours.
• LED’s radiate a "cold light", meaning they generate very little heat compared with other lighting technologies. This also means less wasted energy.
• LED’s are energy efficient meaning they consume less energy to produce brighter illuminated displays that creates much greater readability and flexibility of use than traditional signs and billboards.
• LED’s are manufactured in a full range of colors and with appropriate mixing schemes can generate billions of colors.
• LED’s are continually decreasing in price, making LED displays extremely affordable.
