Frequently Asked Questions about LED Displays

Posted by Derek Klanke on May 30, 2017 10:58:00 AM

 An LED Sign is like a personal billboard for a customer's establishment, except smaller and more customizable. When talking to customers about Electro-Matic's LED Signs, there are some common questions asked which have simple answers:

How long do LED displays last?

Typically, LED displays last for 100,000 hours. If you are running the sign for 24 hours, every day, then this equates to about 10 or 11 years. In most applications, this isn't necessary, so you'll find that your sign can last for many more years.

How much does an LED display cost?

There are multiple determinants of cost for LED displays. All displays are built to our customer’s specification. 

Specifications include:

  • Physical size
  • Resolution of the display
  • Full color or Monochromatic

You can find more information about resoution and color below.

What resolution or pitch should we use for LED displays?

The tighter or smaller the “pitch” is one of the biggest determining factors when it comes to cost. For example, 20mm pitch means there are 20mm of space between each LED in a pixel. So, when you’re looking for a better resolution you would consider upgrading to a 16mm pitch because the LED’s are closer and tDJI_0620.pnghe display will look less pixelated.

Currently the industry is at a 16mm pitch. This is the best dollar per pixel ratio on the market, meaning the best value buy. However, the industry is trending to 12 or 11mm pixel pitch. As the technology gets better so does the price. Also, when determining your pitch, you have to factor in your sign location. Sometimes you may have a sign away from the road 10’ in the air and people are driving 45 miles per hour. In this case, you might not need the value buy and be more cost effective with a 20mm display.

 

While there are standard sign resolutions, your customer's resolution will depend on their sign's size and distance.

What is the difference between a monochrome unit and a full-color led display?

In the industry, there are two different styles of LED Displays. There is a Monochrome single color unit that typically has two options, Red or Amber. These displays are fully programmable with text, graphics or even full animation. However, there is only one LED per pixel that works off a gray scale to show dimensions etc. A Full Color display has 3 LED’s per pixel and are called out by a Red, Green and Blue LED. These 3 LED’s work together to create billions of colors on a display, where you can now utilize text, graphics and animation with a more vibrant look and eye grabbing appeal.

How bright are LED displays?

LED display brightness is measured by NIT levels or the visible-light intensity. Usually displays are around 5000-10000 NIT’s and have a built in auto sensor that reacts off of ambient light. You also have the ability to control NIT levels manually in our software using 129 different options.

How do we send messages to our display?

There are a few ways to communicate with our LED displays. Most of our applications call for a wireless radio connections, that needs a clean line of site with a distance of 2 miles. There are also direct connect Ethernet cable or even a cellular connection. Again, it all depends on each individual application.

How do we create content for our LED Display?

Content creation is done within Electro-Matic’s Windows based software. Our own application engineers will train the end customer on how to use and create content as well as scheduling when the content will show on their display.
