| What is an L.E.D.? |
An LED or Light Emitting Diode contains a chemical compound that gives off light when an electrical current passes through it. Unlike a light bulb, there are no filaments or breakable parts that will ever need to be replaced. The LEDs that AD Systems uses have a life expectancy of 11.4 years.
When considering an LED display make sure you know the brightness of each LED. We recommend LEDs with a brightness rating of at least 5,000 NITS. Many LED companies offer products with a brightness rating of 2,000 or less. This results in a dim sign that will continue to "dim down" over a 3-5 year period. |

| What is a pixel? |
| A pixel is a point of light on an LED sign. An LED sign is made up of an array of pixels (or points of light appearing as dots). A pixel can be as small as one LED or it make contain a cluster of LEDs (2, 3, 4, 6, etc.) that make up one pixel. The closer the pixels are together the higher the resolution of the image |

| Standard Definition |
| Displays offer 1.375" on-center spacing between each pixel producing a brighter image and larger text size that can be seen from long distances. If you will primarily run text and basic animations on your display, we recommend standard definition. |

| High Definition |
| Displays offer .7" on-center spacing between each pixel producing a crisp clean resolution. It also provides more text options for message size. If you will run text, video and detailed animations on your display, we recommend high definition. |

| Viewing angle |
| Is extremely important. You have probably noticed LED signs on the highway that you can read from a distance, but as you get closer to the sign, the message disappears. AD Systems offers a 140 degree viewing cone which allows the LED to be read from the side as well as from the front. Viewing angle directly effects how long your audience can read your messages. |
