What is the lifespan of an LED video wall?

Visualizing real-time intelligence and information is critical in a variety of spaces, from meeting rooms to training spaces to control rooms. These spaces need a single focal point of information that can be easily seen by everyone. We believe video walls are the best solution. Determining which video wall technology is best suited to your application is a little more complicated, however. Here are 10 considerations to keep in mind when deciding between LCD panels and LED tiles for your video wall collaboration technology.

1. Viewing Angle

The term meeting equity means creating equal experiences for meeting participants across all workspaces. These include meeting rooms, training spaces, remote work locations, and across all meeting platforms. 

In today&#;s workplace, video has joined audio as the standard for collaboration. As a result, an equitable meeting experience has to include reliable video capabilities for every participant. To achieve true employee engagement, teams must be able to see and hear each other no matter where they are. 

2. Brightness

Brightness requirements depend largely on where your video wall is located. In a meeting room with a lot of ambient light coming in through the windows, higher brightness is better. But in a control room where users will be tracking multiple feeds of content on the display screen for long shifts, higher brightness is a downside. 

LED tiles offer the best performance for brightness and uniformity when it comes to a tiled array, with 97% brightness uniformity. They can also display content clearly in high ambient light environments. LCD panels typically achieve 85% to 90% brightness uniformity, but they have improved black and low-level gray contrast.

3. Contrast

Higher contrast enables easier and faster recognition of the information being displayed. It also reduces eye strain. Contrast ratios for LCD panels are typically :1, but they can achieve ratios of 500,000:1 with a dynamic backlight. On the other hand, LED tiles can maximize contrast through the use of black printed circuit boards and black solder mask. The typical contrast ratio for an LED tile is :1.

4. Seamlessness

Ideally, any video wall should be completely seamless, but that is not currently 100% achievable. LCD panels can minimize the transition between display screens with bezels of less than 1mm. For large video walls where viewers are at least 10 feet away, the gap between screens is negligible. 

By contrast, LED tiles are designed to touch each other without increasing the distance between pixels from one tile to the next. In a typical tiled array, it is difficult to see where the tiles join from a normal viewing distance.

5. Image Quality

Every video wall looks bright and vibrant when it&#;s new, but how do these two options hold up over time? If color uniformity, brightness uniformity and image quality are not the highest priority for your application, LCD panels are a good and cost-effective solution.

If image quality is important at all times&#;for example in a 24/7 application&#;LED tiles are the better choice. LED tiles can provide high image quality for 5+ years.

How long will your LED display last? In nearly every industry, from retail businesses to concert halls to corporate centers, decision makers need to evaluate the return on investment (ROI) of their LED signage. In most cases, potential buyers go straight to the obvious place: the LED manufacturer&#;s spec sheet. The industry standard for LED lifespan is 100,000 hours, or about 10 years, and most people assume that&#;s how long their display will last. But it&#;s not quite that simple.

The 100,000-hour figure assumes that every diode will be running at full brightness, consistently &#; which, on an LED screen, is virtually never the case. The lifespan figure can also be misleading because it indicates when a diode degrades to half-brightness, not completely dark. Many other variables affect an LED display&#;s lifespan; you can&#;t rely solely on the number on the diode spec sheet.

What other factors influence your LED display&#;s lifespan?

&#;The reality is, your screen can often last significantly longer than 100,000 hours,&#; says Kevin Izatt, a senior product manager in Samsung&#;s Display division. &#;We&#;ve had displays that have been up for 15-plus years with more than adequate brightness. Because the diode is actually only one factor in the lifespan of your LED display.&#;

Here are some of those additional factors:

Weather

The biggest contributor to diode degradation is heat. As you increase a diode&#;s brightness, it produces more heat. Your display&#;s physical environment also contributes to the temperature of the diodes, especially for outdoor displays.

&#;Let&#;s say you&#;re in Vegas &#; Death Valley. The diode is fine to operate at those temperatures, but it will degrade faster,&#; says Izatt. &#;Temperature is a big factor &#; and not one you have control over.&#;

The principle can also work in reverse. If your signage is in Canada, for instance, extreme cold can extend the life of the display.

Power

The quality of your display&#;s power supply &#; and how hard it drives the diodes &#; can have a significant impact on your screen&#;s lifespan. The other components being powered, such as fans and electrical components, have their own lifespans as well, which are also impacted by the power supply.

&#;Fans are mechanical; they break down,&#; explains Izatt. &#;And similar to your computer, the electrical components don&#;t last forever. Together, these factors all contribute to the lifespan of an LED display. Looking at just the diode lifespan doesn&#;t give you the complete story &#; almost always, another part will go out first.&#;

Design

You&#;ll also want to consider the architecture and construction of the unit that houses the screen&#;s diodes.

&#;Something like airflow is very important,&#; says Izatt. &#;You need a screen that has good cooling, and a design that allows heat to flow out of the back through vents.&#;

It&#;s easy to see why: The circuit boards powering the display release heat, and that heat needs to go somewhere. Without a strong design, thermal stress will degrade the life of the display, except for the highest-quality parts &#; optimal conditions notwithstanding.

Content

The content you feature on the display can also affect its lifespan.

&#;Lots of variations on the color and brightness you use will impact the life of the diode,&#; explains Izatt. &#;For instance, black doesn&#;t use any of the diodes at all. And if your content is using lots of gray, that&#;s a much lower power output than white.&#;

That&#;s not to say you should hold back on displaying rich, vibrant colors &#; after all, that&#;s what LED does best. But it does factor into your product&#;s life expectancy.

Swapping LCD for LED

When comparing LED versus LCD screen lifespan, there&#;s no contest. LCDs have a lifespan of about 50,000 hours, or 5 years &#; half the lifespan of LED.

To help businesses transition from LCD to longer-lasting LED signage, Samsung has launched a trade-in program. Samsung will come on site to remove your existing display and provide a discount on a new LED bundle kit.

Traded-in LCD displays that are still operating will be refurbished and resold, and your business will receive a cash rebate. Nonworking displays will be recycled and their parts reused.

Evaluate your display&#;s lifespan holistically

You can&#;t rely on the number on the diode spec sheet; the lifespan of your LED display depends on many more factors. &#;Overall quality has a tremendous impact on the life of the display that diode specs just don&#;t take into account,&#; says Izatt. Your best bet is to look at the purchase holistically and invest in a top-tier product.
