Video Wall

Video wall technologies are at the forefront of data distribution. They not only look cool, but they can also significantly benefit your business and AV projects by transforming a simple display into a high-production value experience.

But how well do you understand video wall technologies? Did you know there are different technologies to choose from? Don’t worry if the answer is no; we can’t all be total AV geniuses.

With this guide to projection-based seamless displays, and panel and cube-based video walls, we hope to provide you with a more comprehensive understanding of video wall technologies.

Ready? Let’s get started!

WHAT EXACTLY DOES PROJECTION-BASED SEAMLESS DISPLAY IMPLY?

The project-based seamless display, the least well-known of the three but equally exciting, does exactly what it says. It’s a video wall comprised of multiple projectors designed to provide a completely seamless experience for those of us who believe that quality is everything.

Large bezels, or ‘borders,’ in screens typically interrupt display, causing images to become disjointed, but projection-based seamless displays allow AV enthusiasts to create larger and higher-quality video walls for a fraction of the cost of a high-quality panel or cube-based wall.

WHERE AND HOW DO WE USE PROJECTION-BASED SEAMLESS DISPLAY?

It sounds a little too good to be true, but the technology is actually quite simple. Edge blending, a very useful technology, allows users to create a seamless display. Edge blending is the process of overlapping and joining the images of two projectors that project different sections of the same image.

This means that the user will not notice any difference between the two projections, and the images will merge within seconds. This is extremely useful for users who want a seamless projection-based display on a large area because it allows them to display massive images with ease!

Geometric correction tactics are also used by projection-based video walls to correct distorted image elements. Essentially, this works by shifting an image’s X and Y axes to mask distortions when projected onto a larger screen. This allows images to adapt to their surroundings, preventing awkward stretching that degrades display quality.

Where we use projection-based video walls is entirely up to the user and their display requirements; this is one of the best aspects of video walls! However, if we had to guess, we could say that a projection-based video wall can be used to display high-quality images in museums, for displays at conventions, and for projecting images onto unusual shapes such as curved displays or cubes.

WHAT EXACTLY IS A PANEL-BASED VIDEO WALL?

Because some of the most well-known brands specialize in this technology, panel-based video walls may be the most well-known examples of video walls. This low-cost alternative to more technologically advanced displays allows users to create large video walls with thin panels.

Because of the presence of bezels on the panels, this technology differs from a projection-based seamless interactive led display. While this may not be an issue for some users, bezels may interfere with the quality of your display; however, this can be managed by a high-quality process that includes bezel mitigation.

WHAT ARE PANEL-BASED VIDEO WALLS AND WHERE CAN THEY BE USED?

Panel-based video walls are made up of multiple panels that function as a single screen. Users can then use processors to isolate panels in order to display multiple bits of information at the same time.

Panel-based video walls can be LCD or LED, but each has its own set of drawbacks. LED video walls provide a bright, high-quality display that is ideal for displaying high-definition images on billboards. LCD panels provide a relatively seamless display, and users can choose a video wall with ultra-thin bezels.

Users should consider colour calibration when using these video walls, as there may be issues with colours remaining consistent across multiple screens.

You might employ panel-based video walls in control rooms because they are designed to be incredibly dependable in mission-critical settings. Here are some examples of control rooms:

  • Control rooms for police officers
  • Control rooms for air traffic
  • Control rooms for processes
  • Control rooms for transportation
  • Control rooms for operations and industry

WHAT EXACTLY IS A VIDEO WALL BASED ON CUBES?

Cube-based video walls are extremely unique and bear little resemblance to their video wall counterparts. Cube-based video walls provide a high-quality experience by utilising large displays that project high-quality images.

These dependable screens provide a nearly seamless display, with bezels as small as 0.1mm in width. This means that users can finally enjoy a high-quality display with little to no interruption in image quality.

As cube-based video walls are designed to be incredibly sturdy and persist for long periods of time, this is another fantastic option for users searching for highly reliable technology for time- and mission-critical control rooms.

WHAT ARE THEY AND HOW CAN WE USE THEM?

An integrated system provides electricity for cube-based video walls. Although it can seem difficult, we can guarantee you that it is not.  Behind each cube on the wall is a projector. This projector is pointed upwards toward a mirror with a 45° slanted surface in order to project the picture onto the screen. This indicates that regardless of screen size or depth, the image is virtually entirely smooth and extremely high-quality.

Although these walls are typically more expensive, users reap numerous benefits in relation to the cost, so it’s important to consider what you’re getting for that price!

Cube-based video walls can be installed in control rooms that require regular monitoring of their activities, as was previously mentioned. A cube-based video wall, for example, could greatly benefit an industrial or transportation control room by providing a continuous display of their network!

What is the purpose of video walls?

There are many uses for video walls, and it really just depends on what each user requires. For example, if a company is struggling with information distribution and suffering from the effects of misinterpretation, a video wall can help centralize information distribution, ensuring messaging comes from a single source and in the same format for everyone!

WHY DO BUSINESSES DECIDE TO INVEST IN VIDEO WALLS?

  • Enhances Their Image:

When clients or customers see a business using video walls, they get the impression that the company values clarity and transparency of information. A company that prioritizes employee transparency values productivity, efficiency, and communication; who wouldn’t want to work with them? Potential clients can also learn via video walls that you prioritise innovation and streamlined services while also staying abreast of current technological trends.

  • Engages Their Coworkers:

Employers can also use video walls to broadcast company-wide announcements to larger teams, ensuring that everyone feels unified and valued at work.

  • Entertaining:

Do you require your own personal movie theatre for a casual Friday event? Not a problem! Video walls are great for entertaining guests and colleagues because advanced video wall solutions can display web browser-based content, making streaming sports and movies a breeze!

  • Surveillance:

Setting up your personal security hub has never been easier.

Thanks to video walls’ ability to display a single coherent image. You can get the full picture with a video wall by connecting your cameras to your controllers.

Giving you peace of mind and complete control over your surveillance.
