A LIGHT-EMITTING DIODE (LED) IS A SEMICONDUCTOR DEVICE THAT EMITS VISIBLE LIGHT WHEN AN ELECTRIC CURRENT PASSES THROUGH IT.

It requires much less power, making it very efficient and making its lifespan much longer than most other light elements. Unlike incandescent lamps, LEDs have no filaments that can burn out or fail.

INDOOR LED DISPLAYS:

SMD (Surface Mount Device) Red Green Blue LEDs in one package. Some outdoor displays do utilize SMD LEDs.

  • SMD LED Advantages:
    • Wide-viewing angle
    • No color shift at extreme viewing angles
    • Smooth color from short distance

OUTDOOR LED DISPLAYS:

DIP (Dual In-line Package) Individual Red Green Blue LEDs

  • DIP LED Advantages:
    • Weather proof
    • Extremely bright
    • Great for longer viewing distance

BRIGHTNESS 

Determining the right brightness for your application  is extremely important. Having a screen that is not bright enough, or too bright, can render your installation useless and ineffective.

Here are a few things to consider when designing your LED wall:

  • Indoor Brightness: 750-1500 nits is enough for most indoor use
  • Outdoor Brightness at close viewing: 1500-3000 nits is usually enough for most situations
  • Outdoor Brightness with direct sun: up to 5,000 + nits should be enough in most situations

Resolution 

RESOLUTION IS THE PHYSICAL DISTANCE MEASURED IN MILLIMETERS FROM THE CENTER OF ONE PIXEL TO ITS CLOSEST NEIGHBORING PIXEL.

The higher the number, the less pixels and the lower the resolution; the smaller the number, the more pixels and higher the resolution. Let’s take one more step. Resolution is the number of pixels contained in the physical area of your LED display. The more pixels you have per square meter, the more detail your wall will display. Overall resolution is determined by display size, pixel technology, pixel pitch and viewing distance.

RESOLUTION VS VIEWING DISTANCE

Understanding how viewing distance and resolution correlate can not only help you better pair yourself with the right product, but also save you a ton of money. Viewing distances are somewhat subjective, but can roughly be calculated based on the display type and the distance from the display. Each display will have a recommended minimum viewing distance that may vary based on application and your intended use.
