If you're in the market for an LED sign you have most likely gone to the internet searching companies that supply this type of product. Your searching the first page of companies and now you're in the "calling for quotes stage". You have spent the good part of the day on the phone with sales representatives. So much information....what to believe? The quotes are rolling in you have 3,4 maybe even 5 to compare. You have narrowed the field down to 2 quotes, so now what? They are both in budget, and appear to be a quality product, so how do you decide which is the best value for the money? One very simple way is to calculate the number of pixels that populate the face of the LED sign and then the total number of LED's on the boards faces.
If you have never heard the term pixel, let me explain it. A pixel is a group of LED diodes that when lit, create an individual dot on your sign. Look at the image below. You can see the individual dots that makes up an image.
Each one of those dots is a pixel. The pixels on the sign make up what is called the active Matrix. Example: 64 x 144. The first number is the number of pixels high and the second, number of pixels long. When analyzing any quote, it's important to see the matrix numbers shown. If your quote does not have a Matrix number on it RUN! Any good company out there will include the Matrix number as a point of measurement that identifies the size of the screen NOT just the cabinet size!
So now the challenge is to figure out which sign is the best value. This is not rocket science! All you need to do now, is figure out which sign has the highest number of diodes on the board. With that information you will know which sign will have the nicest images, and a higher resolution. It's sort of like buying a television, the higher the resolution, the better the image quality. The higher the image quality, the higher the return on investment!
Let's do a simple math formula to determine the actual number of LED's on each vendors product. Start with Vendor #1.
Vendor #1 uses 3 LED's per pixel which equates to: 64 x 144 =9,216 pixels X 3 LED's = 27,648 LED's per face.
Vendor #2 uses 4 LED's per pixel. 64 x 144 pixels = 9216 pixels x 4 LED's = 36,864 LED's
per face.
It's becomes clear that Vendor #2 has the highest resolution/density of LED's per face and is therefore the best value. This is a simple comparison anyone can use and it's so easy!
