With over 30+ years of production experience, we know a thing or two about LED video walls.
Light-Emitting Diodes
LED stands for “light-emitting diode” which is a tiny, two-lead semiconductor light source. LEDs are special because unlike any other technology for digital signage, they can produce and emit light on their own. This makes them long lasting and extremely durable.
Light-emitting diodes are simply tiny little light bulbs that can plug into an electric circuit. Unlike standard light bulbs, however, they do not have a filament. Thus, they do not burn out or run hot. They are illuminated only by the movement of electrons in a semiconductor material. This is also what determines the color of the bulb. Unlike other video walls where the images are backlit, LEDs are actually producing them.
Digital video LED displays began as monochrome and were often used in outdoor digital signage. Everything changed when RGB (color) LEDs hit the market in the late 90s, and direct view light-emitting diode screens are now a major trend in the digital signage industry.
Pixel Construction
As the market for LEDs continues to evolve, pixel density is being greatly improved upon. The gap that once set LED and LCD so far apart is now swiftly closing.
LEDs used in video walls are special because the displays can achieve “true black.” This is done by coating each LED with a black resin epoxy. Shades are then inserted in between the lights to separate the illuminations and eliminate reflectance.
Mounting
Digital video LED walls are comprised of several small LED displays mounted on a flat panel. Therefore, when installing an LED video wall, it is important to keep in mind the average viewing distance. In this case, the number of pixels will determine the resolution. The closer people are to the video wall, the finer the pixel pitch needed.
One pixel in an LED video wall is equal to one surface mount device (SMD). On that small pixel lies the RGB die. The pixel density is calculated by the pitch. The pitch is determined by the distance (in mm) between each SMD LED.
The Benefits of LED Digital Signage
A decade ago, LED technology would not have been a viable option for most business owners. Every day, as the market grows, it is steadily becoming the greatest competition against LCD.
There is an unlimited number of benefits to installing an LED video wall. The following are just a few things you can come to expect from this type of technology:
- High brightness≥ 800 nits
- Designed for high illumination
- Can be displayed in a well-lit room or on a showroom floor
- Great for outdoor video walls
- Handles ambient lighting better than LCD
- Runs on NIT, not Lux
- Seamless: LED panels have minimal bezels (seams) and can be tiled together
- Lower pixel density
- Unmatched uniformity
- Wide viewing angles
- Depth varies, rear access common
- Any size or shape, not just 16:9
- Achieves true black with epoxy coated LEDs
- Wide color gamut ≥ 95% NTSC and accuracy
- Self-emitting light source
LED is an incredibly efficient application for the high-impact visuals that a video wall installation requires. The picture is clear, the integration is flexible and the hardware is more affordable than ever.
We Know LED!
The technology has come a long way in the last 10 years and if it continues to evolve, LEDs stand to be the most prevalent digital signage hardware on the market.
