LED WALLS
(dvLED)
What is dvLED?
dvLED (Direct View LED) walls are advanced display solutions that use individual light-emitting diodes to create high-resolution and seamless video walls. Unlike traditional displays, dvLED walls offer vibrant and sharp visuals with excellent color accuracy, making them ideal for applications in digital signage, broadcast studios, and large-scale presentations. The technology allows for modular construction, enabling the creation of large-scale displays without visible bezels, providing a more immersive viewing experience. dvLED walls are known for their versatility, delivering impressive brightness levels, wide viewing angles, and dynamic content capabilities, making them a popular choice for impactful visual presentations in various professional settings.

AVL Systems Design stands as a fully equipped and proficient entity, possessing the expertise, training, and certifications necessary to deliver comprehensive "turn-key" LED wall systems. Our capabilities extend from meticulous design and seamless installation to thorough training and ongoing servicing, making AVL a singular destination for all your LED video wall needs. With a rich portfolio that includes the design and installation of several hundred LED walls nationwide—ranging from small to exceptionally large and encompassing unique shapes and locations—AVL showcases its proficiency in catering to diverse requirements. Our dedicated Engineering and Installation departments, working full time, are committed to ensuring the successful execution of your LED wall projects. At AVL, we bring a holistic approach to every aspect of LED video wall solutions.
Design
Using the latest in design software, AVL's Engineering team is of the best in the industry when it comes to creating video walls for any application. The AVL Engineering team takes all aspects into account: size, pixel pitch, weight, depth, shape, angle, heat, power loads, sources, resolution, viewing angle, brightness, viewing distance, etc... All of which has to be calculated precisely in order to insure a beautiful, cost affective and long lasting LED video wall for our clients. .
Installation
AVL's Installation teams are fully certified, trained, and provided the best tools in order to install the screen(s) as designed by the Engineering team. The Install teams are also extremely careful and precise. They take not only follow the AVL Engineered drawings, but will make adjustments to meet the site conditions without delaying deadlines. We truly believe we have some of the best Installation teams in this field, and are proud of the work they do for our clients.
Service
Servicing LED walls can be extremely easy or somewhat challenging. It is rarely in-between. Fortunately, our of the several hundred LED walls installed by AVL over the past few years, we have only had to replace one rear module.
3 Basic Starting Steps
Step #1
Pixel Pitch & Viewing Distance
Viewing Distance:
-
The primary factor in determining pixel pitch is how close the nearest viewer will be to the screen.
-
If viewers are very close, you'll want a smaller pixel pitch for a clearer image. If they are far away, a larger pixel pitch might suffice.
-
For example, for very close viewing (like a computer monitor or a phone), the pixel pitch is typically under 0.3mm. For a billboard that's viewed from tens or hundreds of meters away, the pixel pitch might be 10mm or more.
Pixel Pitch Reference:
-
For close-up indoor viewing (like in a retail space or gallery), you might look at pitches from 0.9mm to 2.5mm.
-
For general indoor applications (like in a conference room or auditorium), pitches from 2.5mm to 4mm might be suitable.
-
For outdoor applications where viewers are farther away (like on a large billboard or stadium screen), pitches from 4mm to 10mm or more might be appropriate.
Pixel Pitch:
-
Pixel Pitch is the distance from the center of one LED (or pixel) to the center of the adjacent LED. This is a measure used to define the resolution and clarity of an LED display. The smaller the pixel pitch, the closer the LEDs are to each other, meaning more LEDs per unit area, which usually translates to higher resolution and clearer pictures.
-
Ultimately, if possible, it's a good idea to view LED walls with different pixel pitches in person. AVL can demonstrate pixel pitch viewing sizes in our show room, or can take our clients to a multitude of installations and designs that AVL has completed across the US.
Step #2
Content, Brightness & Size
Content Resolution:
-
If you’re showcasing high-resolution content (like 4K videos), you’ll want a finer pixel pitch to ensure clarity and detail.
-
However, if your content doesn't require high resolution (e.g., large text on a scoreboard), then a larger pixel pitch might be sufficient.
Brightness and Ambient Light:
-
If your LED wall is outdoors or in a well-lit area, you might prioritize brightness over resolution.
-
In such cases, a slightly larger pixel pitch (which can be brighter due to larger LEDs or more space for backlight) might be acceptable.
Screen Size:
-
Consider the overall size of your LED wall. A very large screen might still appear clear from a distance even with a larger pixel pitch.
Power:
-
No matter what size or shape, specific type of power is always needed. This can be overlooked much of the time. Some walls simply take one dedicated 110v/120v power source per screen, like an 8x10 foot screen or lower. Sometimes, depending on the brand, and max brightness needed, we can reach 16' x 9' screens on one singe, dedicated 110v/120v source. Most larger will require multiple hot legs, and/or multiple single/3phase connections per wall.
Step #3
Cost & Planning
Cost:
-
Costs of LED walls in the past have been high in comparison to projectors and multi-LCD screen walls. Now, costs have been very competitive to your typical larger format screen equipment. Especially against the multi-LCD screen Walls, and brighter projection systems.
-
Typically, screens with a smaller pixel pitch are more expensive because they have more LEDs per unit area.
-
You'll need to balance the desired resolution with the available budget
-
If you choose a certified, trained and properly insured company like AVL Systems Design, your labor costs can be much less than others. AVL carries all appropriate insurance, certificates, and certification of the manufactures we provide.
-
All structural, electrical and installation planning done by our own Engineers. If a project is pushing the boundary's of a typical LED wall install, AVL will always get the approval by the manufacture prior to implementing on site. We have seen so many fail and cost the client far more having to higher AVL to come in and re-do/fix the situation after the fact.
Planning:
-
How it will be installed.
-
Will it be mounted directly onto a wall,
-
Or, will it be dead hung from the structure,
-
Or, does it need to be raised and lowered via a motorized pully system,
-
Or, will it be portal,
-
Or, will it be portable & modular?
-
NOTE:
-
It is always a good idea to do some good, diligence background checkup on the AV contractor you are thinking of using.
-
Have the contractor provide a list of the most recent projects completed with LED walls similar to what you are wanting. A lot of them will verbally mention or allude to a project that they did, but in realty they either didn't do it or they may have been called on to work on it. Get it in writing.
-
Do they have the proper liability insurance?
-
What manufacture(s) does the contractor work directly with? Not via distrobution only.
-
Contact the manufacture that they are proposing. Ask if they are comfortable/approve of the company that you are looking to hire. If they are not, ask for recommendations. This will save so much time, frustration and money in the long run.
