LED Video Wall vs. Projector

One of the most common questions posed by someone new to A/V and display technology is: 

What’s the difference between an LED Video Wall and a projector? 

In this article, we shall explore the main pros and cons of both technologies.

Projectors are widely used for many visual communication applications

Projector

LED Video Wall

Pros

  • Relatively more affordable
  • Higher definition for the cost
  • Relatively lower technical skills required for operation
 
 
 

Cons

  • The image reflected by the light throw from the projector.  The image is generally very dim. Any ambient lighting needs to be turned off for good viewing, otherwise, the image will look “dull“, “washed-out” or gray.
  • Image quality is also a function of screen material and quality 
  • Steeper degrade curve on the lamp. Maintenance of Lamp usually at 5000 Hrs while Long-life Lamp is rated at 20,000 Hrs
  • Screen size limited to a certain size <200″ or so
  • Limited mounting location due to obstruction of view or throw distance

Pros

  • LED generate the image directly  (direct-view vs. projection) Bright, 1500 NITS and up and offers a greater contrast
  • Image not susceptible to obstruction
  • Modular and scalable to any size
  • Long lifespan (50k-100K hours) depending on ambient conditions.

Cons

  • Generally more costly than a projector, but reaching parity with high lumen projector as the cost continues to drop
  • High initial investment
  • More costly to mimic the resolution of a projector.  Fine-pitch screen (<1.2mm) must be used.
  • Very costly fine-pitch models must be used for close viewing applications
  • Higher technical knowledge needed to operate

Bottomline

If the budget is limited or if image quality is not the utmost consideration, one should consider projection. Projection is also mostly used for residential applications.

LED Screen is definitely the way to go when the utmost,  professional visual quality is expected. This is especially true for Corporate, Commercial or House of Worship applications. 

As the cost differential between the two technologies approaches parity, it’d be worthwhile to get both estimates and compare!
