What is a display wall (Video Wall)?
A display wall / Digital Signage (also known as a video wall) is a large surface containing numerous displays. They were initially several televisions or screens put together to make it seem like one large screen using Video Wall mount i.e 4×2 video wall.
New thin edge technologies were introduced to minimise the hidden space between the multiple screens. Now, wall solutions are generally using tiled LCD panels, projection, or direct LED tiles.
These display walls are available in many sizes, usually with a diameter from 46″ to 80″. But the choice of the screen size depends on the specific content and the viewing distance. The resolution depends on the size of the Video wall.
Video LED Walls are mounted in meeting rooms, control rooms or for display and advertisement.
Example LED Wall Configurations
4×2 video wall, 2×2 , 3×3 ……. and so on 4×4
Common traits:
- Wall Video controller to get content on the screens
- Digital Signage
- Calibration mechanism to ensure every tile have the same brightness and colour settings.
- Minimal inter-tile gap (or ultra-narrow bezel) to counter the ‘raster effect.’
- Flexible regarding the number of LEDs (screen size)
About LCD walls
LCD wall consists of multiple specifically designed LCDs, these LCDs have a very narrow bezel. The LCD display wall minimizes the gap between the panels, making it look like one big canvas. Today, Tranquil Mount MV70 has the smallest gap between the panels.
In addition, LCD display walls are designed for long term use. Specific measures are applied to prevent burn-in effects from allowing them to play for many years, in optimal conditions. In some cases, they continuously play in a 24/7 mode, which means they are rarely switched off.
Display Wall Solutions’ traditional benefits include the high brightness, acceptable image quality, and relatively low cost. The disadvantages are the risk of burn-in and the lower lifetime. However many LEDs today have tackled that problem, so there is no worry of burn-ins happening.
Typical markets for LCD walls include meeting and crisis rooms, lobbies, and experience centres. They are also found in control rooms of traffic and security centres.
Rear-projection
Now using projection, rear-projection video walls target different applications. They are optimal for 24/7 use. Utility providers mostly rely on technology to monitor networks.
A rear-projection video is a wall that consists of multiple cubes, which contain a projector and a screen. The projectors are tilted towards a mirror under a 45° angle reflects the image onto the screen. This means that the required depth is cut dramatically. The Projection can also be serviced from the front, so there is no need for a rear maintenance area.
This technology’s benefits include the very high runtime, an absence of burn-in, and a narrower gap between cubes. Traditional drawbacks are the limited brightness and the real estate space used.
LED Display walls
Direct view LED technology is used to create the most intricate video walls. Live performances use LED video walls to add effect. The LED display tiles contain many individual colour LEDs.
The high brightness, absence of gaps between the screens and impressive colours are the main benefits of this technology. The disadvantages are high cost and power consumption.

Screen resolution
A factor affecting the cost of the wall solution is the resolution of the LED screen. Resolution is determined by the number of pixels in a fixed area. A higher count of pixels will produce an image with a higher resolution.
The audience’s distance determines the decision of what resolution you need to the led screen. The further the screen from the audience, the lower your resolution needs to be (like a concert, for example.)
LED screens with a higher resolution can dramatically increase the price too. These screens require high-end processors to produce imagery at a higher resolution. So if you choose to change to a higher-resolution display, the LED screen’s cost and its usage cost will increase.
