Understanding an LED Video wall doesn't necessarily need to be complicated. Having said that, we will be discussing one of the important points of an LED Video Wall called "Pixel Pitch."
Making a decision to purchase an LED Video Wall can be an easy thing to do. However, researching its components and technical jargon can be a daunting task. Especially when trying to understand and choose based on resolution, which LED Video walls call pixel pitch.
What’s a Pixel Pitch?
In order to understand what a pixel pitch is let’s understand the anatomy of an LED Video wall. An LED Video wall is built out of panels, a number of modules, and a number of clusters of LED lights that sit on the modules. These modules are the housing for the LED lights which together emit light and ultimately an image. Let’s get back to the pixel pitch.
When you look at the module you will see the number of LED lights, each LED light has a precise measurement from the other. If you take the center of one LED light, or pixel, and measure its center to an adjacent center of another pixel you will find a measurement in millimeters or in this case, the pixel pitch. The less space and more clusters are on a module the higher the resolution, or the lower the pixel pitch. For example, it’s common to see a church with an indoor LED Video Wall with either a 2.5mm (Pixel Pitch/pp) or a 3.9mm (Pixel Pitch/pp).
Let’s summarize, a pixel pitch refers to the resolution of an image on an LED Video Wall. The lower the measurements on a pixel pitch the higher the resolutions. Today’s technology offers a number of options.
Looking for the best Pixel Pitch?
This not a simple answer because there is a number of variables that need to be factored in
before concluding the right choice. As a matter of fact, we don’t say that we offer the best pixel pitches. We say that we have a pixel pitch that fits your application.
LED Video walls offer a number of pixel pitches for a number of various applications. The LED Video wall industry technology is currently offering 1-20mm Pixel Pitches, and every pixel pitch has a minimum recommended viewing distances, but I’m jumping ahead. Let’s talk about a few different parameters, 3 to be exact, that we ask you to keep in mind during your due diligence.
1. The Ideal Viewing Distance
Every Pixel Pitch (pp) has a minimum recommended viewing distance as we mentioned before. The lower the pixel pitch, for example 1-3mm pixel pitch, the closer one is able to enjoy the LED Video Wall without being distracted by the pixels and the outlines of the modules/blocks, but there’s a limit of how close you can be from the screen which in this case would be 5-10ft.
For larger Pixel Pitches, you definitely will need to be further way. A billboard on the side of a freeway or outdoor digital signage normally has a pixel pitch of 10-20mm. This size of pixel pitch will require a recommended distance of 40+ ft.
2. Display Size
We can get really deep into screen sizes when choosing the right size. But, let’s take a look at the choices. Worship Productions provides you with a few selections to choose from. We carry your typical large display, small display, or columns. When considering the size, one needs to consider the aspect ratio. The most common aspect ratio since 2009 is 16:9. This aspect ratio works for HDTV Full HD, computer monitors, YouTube, online videos and of course LED Video Walls.
An LED Video wall with a 3.9mm and a 2.5mm are different in two ways, pixel distance and panel size. A 3.9mm (Pixel Pitch) has a panel size that is 500mmx1000mm, while a 2.5mm has a panel dimension of 640mmx640mm. Your choice of Pixel Pitch can affect the number of panels you will be using during your installation.
We should also mention, like any screen with higher resolution there will be higher costs associated. This usually is the case because of the following considerations, the manufacturing process is tedious since the LED density increases. In other words more LED’s on each module, the increased wiring, and the overall fine pixel manufacturing.
It’s important that you consider these 3 points when purchasing your next LED Video wall. Remember, Viewing Distance, Display Size, and Cost. Our goal is to equip you with the right knowledge that will help you make an informative decision for your next purchase.
