LED technology was invented in the 1960s. At first, red was the only color available, and the light intensity they produced was low.

Back then, the digital displays were only used on clocks, radios, and televisions. However, as the years have gone by, the technology has become more advanced. Electronic signs now come in a multitude of colors with higher light intensities.

Even the applications have evolved. Today, full color LED signs have become one of the most effective forms of advertising. Close to 40% of people indicate that they spend most of the time looking at outdoor digital signs each time they pass one.

Among the institutions benefiting from this technology are schools. Digital signs for schools have become useful for administrations as they help improve communication and increase safety, among other things.

What Type of Content Can Be Displayed on Digital Signs for Schools

  • Sports and fundraising events
  • Campus maps /li>
  • Emergency alerts and instructions
  • Scholarships and bursaries
  • Schedules for after school activities
  • Exam dates /li>
  • Student projects
  • Welcome messages to parents and guests
  • School events such as graduations and dances

To deliver the message effectively, digital signs are customized for their intended use. Therefore, several things should be put into consideration when buying outdoor LED school signs. They are:

1. Viewing Distance

When shopping for outdoor LED school signs, it is vital that you take into account the distance of the audience. This will help you determine the appropriate size and pixel pitch. Some of the factors you should consider are…

  • View-able area
  • Pixel pitch
  • Matrix

There are no predetermined standards to guide you on this choice. However, you will be able to choose an electric sign based on comparisons.

2. Pixel Pitch

Pixel pitch refers to the density of pixel on your electronic sign, and it correlates with resolution. It indicates the center to center distance between adjacent pixels and is measured in millimeters.

A small pixel pitch indicates that the empty space between pixels is smaller and that the display has more pixels. This translates to a higher resolution and better image quality. A low pixel pitch value will give the image finer details and smooth borders. This will then reduce the minimum viewing distance as viewers close to the display will not have to work out pixels individually. Conversely, with a higher pitch pixel, the minimum viewing distance will be longer.

Though a lower pixel pitch value results in better image quality, it is not necessarily the best option for all scenarios. It is only suitable when the viewing distance is short. Otherwise, as the viewing distance increases, the advantage it has on clarity reduces.

Therefore, to ensure your outdoor LED display is both effective and cost-efficient, establish the minimum and maximum viewing distance. This will help you determine the pixel pitch that is suitable for everyone in the viewing area.

3. Environment

LED displays can be used for both indoor and outdoor use. Displays for each setting must meet unique conditions suitable for their environment. For instance, an indoor display should offer an excellent resolution. On the other hand, an outdoor electric sign should have a very high bright display to ensure visibility under the reflection of the sun.

Also, outdoor displays should be geared to survive extreme weather conditions. The intended location for the display should guide your choice.


The goal of communication is to deliver a message to the intended recipient at a convenient time. Digital signs enable school administrations to communicate to students, staff, and guests in an efficient and cost-effective manner.

By installing a network of display signs in your institution, you will also be able to curate messages for specific audiences. Now that you know about viewing distances and pitch pixels, you are ready to shop for outdoor LED school signs.
