LED technology has evolved a lot over the years, making display decisions increasingly complicated. Marc Lemieux, Principal Architect of Display Technology at Christie Digital Systems, joins The Collaboration Space to help demystify LEDs and tell us what to consider when choosing video wall solutions.
Demystifying LED video wall technology with Christie Digital Systems
The advantages of LED displays
LCDs and projectors have been around for a long time. But LED displays have become increasingly popular due to their many advantages, especially in specific applications. Even though they may cost more initially, LED displays are a good investment in longevity and energy expenditures. Here are some of the most significant advantages of choosing LED video walls.
Brightness
A significant advantage of LED displays is that they can be up to five times brighter than LCD panels. Their brightness and higher contrast ratio mean they can be deployed in high-ambient light environments without looking washed out.
Color saturation
LEDs provide a wide color gamut, so displays have a bigger impact with more vivid and saturated colors.
Flexibility
A technology provider can build LED video walls in various shapes and sizes to suit the space.
Higher density
Tri-color, surface-mount LED technology enables smaller, higher-density displays with better resolution.
Seamless experience
LED video walls are seamless for applications where you don’t want to see bezel between a wall’s screen panels.
Reliability and longevity
LED video walls feature solid-state technology, giving them a longer lifespan of about 100,000 hours.
What to look for in LED video walls
With all the solutions on the market, what should you look for? You can prioritize certain features based on the size of the space, the end application, viewing distance, whether it will go inside or outside, and the ambient light environment. Once you have determined those details, here’s what you’ll want to consider.
Pixel pitch
Pixel density affects resolution and should be chosen based on viewing distance. For example, a low pixel pitch means the LEDs are close together for closer viewing. A high pixel pitch would be more spread out for viewing from a distance.
Durability
Look for a platform that will last and you can upgrade over time. LED video walls are a significant investment, so consider whether modules are encapsulated for protection, especially where passersby may touch them.
Mechanical design
Modular video walls are made up of tiles or blocks. They can also be made of micro tiles or blocks to create more varied designs, including curves and corners.
Extreme temperatures
Some LED displays generate a lot of heat, causing thermal expansion. Also, consider how external temperatures can affect the video wall. Your technology partner can help you address these issues to keep your wall looking good for years.
Energy efficiency
Evaluate the energy use of any potential LED video wall. Some display solutions run from many hours a day to 24 hours a day.
Compliance
If you’re planning a video wall for specific industries or a government agency, you may need to consider certain specifications and requirements like TAA (Trade Agreements Act) compliance which regulates where products are built.
Installation and service
Ask about what kinds of video wall installation services and ongoing support your technology partner provides.
The future of LED technology and solutions
LED technology continues to change. And Christie Digital is always innovating with solutions like their MicroTiles LED. This product is unique in that it’s designed as a platform that can evolve as technology does. Emerging LED technologies include microLED chip-on-board (COB) displays and encapsulated MicroTiles that allow for interactivity.
