When considering making the advertising investment of an EMC (Electronic Message Centre) for your business you want to ensure that you are buying the right product for your needs. There are many things to consider when choosing and EMC such as viewing distance, the speed of passerby's, optimal size, durability and pixel pitch to name a few. EMC's are great advertising investment for your business and you want to be sure you are getting the best value for your money. Below is an expert from a good article to help understand PIXEL PITCH...
Pixel Pitch & Exterior Displays
Given the range of environments and conditions for exterior LED displays, there are many factors to consider. As with interior displays, pixel pitch is among the most important. For many billboards and building façades, viewers are typically long distances from the display, meaning pixel density may be of less importance. However, there are walk-up outdoor applications as well, where high resolution (tight pixel pitch) is paramount. Additionally, in busier environments where multiple displays are competing for attention (think Times Square or Las Vegas), a higher-quality, higher-resolution display is of much higher value.
And finally, when choosing the right pixel pitch for your display, there are functionality considerations as well. Suppose a display owner wants to take a simple messaging approach with only text and unsophisticated graphics. In this case, a higher pixel pitch (less pixels, lower resolution) might be sufficient. On the other hand, a retailer who has carefully crafted a high-end brand with premium products may want a tighter pixel pitch (more pixels, higher resolution), not because of viewing distance but rather for image quality and better functionality.
What’s Best for My Application?
As you might expect, this is a very loaded question. There are many factors you should consider before making an investment in an LED display. If you’re not an expert in this technology, it’s extremely important for you to find one—a manufacturer, a consultant, an experienced buyer—you trust to help guide you through the decision process.
As explained above, pixel pitch is a huge consideration for this process. It goes hand in hand with other factors such as display size, viewing distance, ambient light conditions, weather and moisture protection, competing media, messaging functionality, image quality and much, much more.
Properly deployed LED displays have the capacity to increase traffic, improve audience engagement, and enhance customer experience. But understanding how the technology will impact both the viewer and your bottom line prior to investment can empower you to make the best decision for your specific needs and budget.
We believe well-informed customers make better decisions for their display needs, leading to better experiences for all involved, and, ultimately, healthier long-term relationships.

LED signs, churches and places of worship.
LED signs are an extremely cost-effective form of communication. A new LED sign in conjunction with your new or existing signs can cost less than 15 cents per thousand exposures while reaching the very people who are geographically close enough to act on your message immediately. How important is it for you to keep your congregation informed and growing? With an attention-grabbing LED message center, your church can reach out with inspiration and excitement to your flock as well as the surrounding community. LED displays provide energy-efficient communications 24/7, using light, color, and motion to bring greater visibility to your congregation’s programs. With the addition of an LED sign, your church can become your community’s beacon of light.
Benefits:
• Extend a warm welcome to newcomers and passer-bys
• Share daily or hourly affirmations with your whole community
• Communicate weddings, festivals and special events
• Promote school spirit, sporting events, and student activities
• Acknowledge student, staff and ministry achievements
• Seek community support for fundraising events
• Draw attention with time, temperature and date displays

Via WatchfireSigns.com Pixel pitch is a common way the sign industry describes an LED sign’s resolution. A pixel is comprised of a single grouping or cluster of LED diodes – typically one red, one blue and one green. The pixel may share a lens, as in the case of a surface mount diode, or it may be made up of three separate LEDs.
The simple rule of thumb is that a lower pitch measurement, where each cluster is close together, results in a higher quality image. Unfortunately, some manufacturers have introduced alternative pixel distance calculations as a way to reduce costs. These configurations are often marketed as “virtual,” “enhanced,” or “optimized.” Here is a look at a few different pixel options and how they impact image quality.
The Real Deal: True pixel configurations are measured from the center of each pixel and do not rely on sharing LEDs. Watchfire’s 10mm uses a surface mount device (SMD) that contains red, green and blue under a single lens. This produces a high-quality display that provides exceptional resolution for crisp, vivid content and wide viewing angles.
The Two-Red Imposter Module: Virtual pixel configurations are set up completely different. In order to pass off a lower resolution product, some manufacturers will add a second red LED to each cluster. This configuration results in a pixel that has two red, one blue and one green LED. Then to claim the product is high resolution, these deceitful manufacturers will market it based on the measurement between each individual LED. The product will be marketed as an optimized 10mm, but in reality it has a true pixel pitch of 20mm.
The Missing LED Module: Another way some manufacturers are being deceptive is by using a technique known as LED sharing to claim a higher resolution. LEDs are shared to neighboring pixels to complete a grouping, effectively counting some LEDs up to four times. This layout has visibly larger spaces between LEDs and may even give the appearance that an LED is missing from the board layout. To market this configuration, pitch is measured between overlapping pixels so that the product can be promoted at a much higher resolution than it actually delivers.
The Cold Shoulder Module: Some manufacturers also use through-hole LEDs for higher resolution products like a true 10mm sign. Placing individual red, green and blue LEDs into a circuit board with 10mm spacing creates a product that is not robust enough for long term reliability. This configuration also creates an issue known as shouldering, where the LED lenses block the light of neighboring diodes. Shouldering results in limited viewing angles and can make the display look discolored when it is viewed off-center.
Disadvantages of Virtual Pixel Configurations: LED sharing results in weak color contrast and uneven edges on text as the pixels bleed into one another when they overlap.
Virtual resolutions with two red LEDs cause white graphics and text to look pink because red LEDs dim at a slower rate than blue and green.
Pixel layouts that use 4 LEDs do not allow for consistent black space. This results in fuzzy images that may appear washed out.
Color blending suffers on virtual configurations using the missing LED layout, compromising image quality.
