NOT ALL SEALANTS ARE CREATED EQUAL
Have you ever wondered how all those outdoor LED displays withstand the elements? How do they stay water and debris-resistant? Well, read this blog post to find out.
These days, you don’t have to stay indoors to enjoy the beauty of picture-perfect LED displays. Outdoor displays are everywhere, whether that be LED billboards, business signage, a giant scoreboard at a sporting event, or even a massive video board at a concert in the park. But as you look up at them and say aloud, “Wow, that LED screen is breathtaking,” you may also be wondering, “But how is that screen protected from the elements?”
By elements, we mean all the standard stuff — rain, extreme heat and cold temperatures, wind, dust and debris, bugs, etc. It shouldn’t take long for any of those elements to completely ruin any LED display.
Your friends at Azar Pixel have the answer, and without getting too technical, it all comes down to protecting pixels!

Indoor vs Outdoor Displays
Indoor and Outdoor LED displays are made up of a number of smaller, individual units called modules. Each module is made up of tiny, three-colored (red, green and blue) pixels, which, as we all know from a previous blog post, are millions of tiny colored dots that, when working together, create a picture-perfect continuous and realistic image. A pixel is the smallest unit of a digital image or graphic that can be displayed on a screen, so they are essentially the individual building blocks of every digital image.
They are also very sensitive to the elements and must be protected at all costs. There isn’t too much concern with indoor LED displays because their internal components are indoors — far away from anything that could compromise the unit.
But outdoor units require special silicone sealant to create an impermeable seal around each pixel. From the outside, there is nothing to see. But if you were to take off the shader (or, the plastic screen surrounding and protecting the pixels) from the front of the module of an LED display – especially if Azar Pixel’s pros worked on the unit – you would notice right away that each pixel is surrounded by black silicone sealant.
Furthermore, on the backside of the unit, you would find a high-quality clear urethane coating to provide protection from the elements to the Integrated Circuit Chips (IC’s), the Printed Circuit Boards (PCB’s) and other components as well as allowing damaging heat to properly dissipate from the module. Using the right sealant for both the front and back of the module is crucial!

Choosing The Right Sealant
When it comes to your outdoor LED display and LED modules, we can’t stress enough that not all sealants are created equal. You can find cheaper ones on the market, but the majority of them are made with filler. That may not seem like a big deal, but over time, these fillers dry up, crack, and even shrink — putting your LED pixels at risk by exposing them to the elements.
What one needs to use is pure silicone, which substantially outlasts the cheaper silicones over time. Pure silicone may cost a little more in comparison to other inferior silicone products, but the advantages are important and include:
- More Stability and Resistance To Harsh Elements
- More Flexibility
- More Microbial/Mold Resistance
- …And, A Longer Lasting Seal
You can be sure that Azar Pixel is using only the finest of materials to insure a tight, long-last seal for all outdoor LED Modules we touch!
