LED VIDEO
TECHNOLOGY

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. LED video walls are comprised of Direct View LED displays (also called DV) that work together as a unit to display content as if it were a single screen. LED screens are incredibly efficient because each component is responsible for conducting and emitting its own light.

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:

Lighting :

• High brightness

• 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

Reliability :

• Energy-efficient and long-lasting

• Long-life

• Best refresh rates of any video wall on the market

Installation :

• 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

Quality :

• 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. 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.
