Introduction to Dynamic Billboards AKA LED Signs

LED signs are digital billboards and otherwise known as changing message signs or dynamic billboards. They work electronically and give users the freedom to display their advertisements with various digital content like text, videos and graphics.

The key advantages of LED signs are:

  1. The fact that they can display multiple messages, advertisements and other information.
  2. The fact that they conveniently allow the information displayed to be changed at any time.

LED signs/dynamic billboards work through light emitting diodes. These diodes cluster together and form pixels which are connected in a sequence of both rows and columns. These rows and columns of pixels create the sign’s resolution which is also known as matrix, or pixel matrix. When there are more rows and columns there is a higher resolution.

Pixel density is another important factor. It is the number of pixels within a specific area of the LED sign. This is also determined by how many rows and columns are present and how close they are together. Pixel density, just like a higher resolution, results in a much better-looking LED sign.

When looking for a good resolution for a LED sign, the factors to consider are:

  1. The dimensions of the display area.
  2. The type of content that is to be displayed such text, video or graphics.
  3. Where the LED sign will be installed.
  4. What the viewing distance will be for the target audience.

Understanding these four factors is key and can be done by understanding LED modules, otherwise known as tiles. The modules are a result of the connected pixels on a small PCB which is the small circuit board. Several of these modules together form the ultimate dimensions of the sign. Therefore, the dimensions of the sign determine the number of modules needed.

Different combinations of pixel density, size and the number of rows or columns create various categories of the LED modules. These include: P2.5, P4, P5, P6, P8, P10, P16, P20 and such.

The category determines the space between pixels which then determines the quality of the resolution. More space means lower resolution for higher number categories while lower number categories have more density, rows and columns therefore a much higher resolution. Large pixels are best for LED signs that will be seen from further away while smaller pixels are best for close up viewing.

To determine the best solution for advertising your business on a LED sign, consider what will be advertised and in what way. Then decide on the largest possible size of sign that can be installed, where it will be installed and how far the viewing distance will be.

Outdoor LED signs typically need to be P8, P10 or P16 for the best results. The outdoor LED signs should be brighter because they target viewers from a further distance.

Indoor LED signs typically need to be P2.5, P4 or P5 for the best results because viewers see them from a much closer distance and it makes them far more easier to see.
