What Makes a Quality LED Display?
An LED display’s quality is judged by a long list of marketable specifications, like perceived image performance or reliability. But it’s hard to know exactly how these specifications are being calculated when reading a specification sheet or brochure from a manufacturer.
Consider this: fine pitch (or narrow pixel pitch) LED displays have been on the market for about seven years and the lifetime of an LED may be upwards of 100,000 hours, which is equal to more than 11 years. If LED displays have been sold for less than their average lifetime, how can we be assured that we are investing in quality display components?
There are three key aspects to consider when seeking to select a high quality LED display:
- LED Image Performance: The first key to overall performance is the individual LEDs. This is where the image is born, so the consistency, stability, and reliability of the individual LEDs is critical for image performance and long life. The size of the LED also governs the pitch of the pixels, which is the determining factor for resolution and thus image quality. The efficiency of the LED affects the total power consumption, which affects the cost of operating and the thermal considerations of the installation. LEDs also have variation in brightness and quality during the production process, and are routinely sorted (binned). Manufacturers have a choice of LEDs and high quality brands should be using the highest quality components.
- Drive Electronics: Second to the LEDs themselves, how they are driven electronically is critical in overall reliability, power, and image fidelity. There are different drive methods, and some are much better than others overall. Again, manufacturers have a range of choices from external vendors and in-house development efforts which yield a wide variety of performance.
- Mechanical Design: The mechanical design—especially as it relates to alignment and mounting depth —is critical for forming a seamless image with multiple blocks. The human eye is very discriminating when it comes to uneven gaps between blocks, so keeping the seams perfectly aligned and flush is critical. If the modules are too close, the eye will perceive light or white lines. If the modules are spaced too far, you will see dark or black lines. For service reasons, it is very desirable to have front serviceability of individual tiles. This places even more demands on the mechanical design to both maintain alignment and allow front servicing.
As you can see, it all comes down to design choices and manufacturing.
So who do you trust to build YOUR LED video wall?
Leyard is the leader in fine-pitch LED technology, earning the number one market share position not only in fine-pitch, but in the LED category overall. Many of our design and manufacturing processes that allow us to accurately and reliably assemble LEDs for our fine pitch displays are proprietary, developed over our history of innovation in this space.
As a pioneer of the category and the market leader we have the most experience and control over the LED components themselves, which, as we highlighted above, is where it all starts. We use the finest grade LEDs with the best consistency and reliability. We have developed the precise manufacturing techniques to accurately and reliably assemble even the smallest LEDs to make the world’s finest pitch LED displays. Our electronic drive and calibration techniques are the most efficient and accurate in the industry. Our mechanical designs are second to none in terms of alignment, stability, serviceability, and thin form-factor.
We are extremely proud of the industry that we helped build in fine pitch LED and what our customers are doing with the technology is remarkable. From the ceiling of a delegate hall at the United Nations to the floor of the Beijing Olympics Opening Ceremony, from the walls of marquee retail brands to corporate board rooms around the world – our products display our quality.
