Therefore, they are suitable for work in rooms with a large number of people as the most practical. Video complexes are installed in:
- dispatch centers
- situation centers
- simulators
- TV and radio companies
- Conference rooms
- lecture halls, etc
Purpose of video wall screen display technology
The width and height of video wall screen display reach, as a rule, up to several tens of meters.
The forerunners of video wall panels were scoreboards – in contrast, the video wall screen display is supplemented with the functions of scaling content, instantly displaying new ideas on the screen, broadcasting from an unlimited number of channels, and so on.
A video wall controller is needed when data comes from several sources at the same time: it also helps to change the position of the picture outside the frame of LCD video wall panels. Manual channel switching is not required when using it.
This technique is also capable of providing broadcasts in direct mode: thanks to the demonstration characteristics of the system and in the presence of equipment for uninterrupted communication.
Video panels are also installed for advertising purposes due to the detailed transmission of the picture. The devices handle both photo and video content well.
Video wall screen: Types and differences
Video wall screen display have several parameters by which they are classified:
- Swing length . A diagonal of 46 or 55 cm is recognized as a classic, capable of functioning around the clock for several years. The duration of continuous operation is what distinguishes video panels from simple widescreen TVs.
- Number of modules . The most popular are 2×2 video walls out of four monitors or 3×3 video walls out of nine.
- Seam width . A gap of more than 5.3 mm is considered impractical and outdated – these are almost never produced today. Current models have seams between 1.7 and 3.6 mm and are considered “seamless”.
- There are video wall mounts : floor, ceiling, wall and floor-to-ceiling.
- Brightness is measured in candela per square meter, the ideal value for a wall is 500. There are also devices with a brightness of 700-800 cd / m2, used in rooms with increased lighting.
An ordinary wall is made up of video cubes, which, by their design, can have rear or front access.
Cubes range in size from 20 to 100 inches diagonally. They are built into the front panel in such a way as to leave gaps of no more than 1 mm. Rear access allows you to reduce the distance, but the front, on the contrary, increases it to 2 mm and increases the cost of cubes.
Another option is LCD parts that have a liquid crystal display. The gap between the frames of the panels is larger than between the video cubes – about 3-6 mm, and they are also inferior to them in performance. Video wall LCD panels cannot operate 24 hours a day and must be turned off for 2-3 hours to prevent residual pixels.
The third type is LED panels for video walls, made up of LEDs. The pixel size can reach 3-5 mm, therefore, such models are mounted outside as an advertising design. Brightness and good color reproduction make them noticeable even in bad weather.
What are the requirements for the device:
- long planned service life (from 3 years)
- seamlessness – a system with seams more than 3.5 mm will be impractical, moreover, it is almost impossible to replace it, since they are almost discontinued
- fasteners and wires included
- availability of a guarantee
Video wall screen: overview of the most important features
Video wall screen display device
In addition to displays and mounts, the kit should include a device that is capable of transmitting information to the screen. If there is only one source, then you can connect it without additional equipment: each wall has its own switch, so it is enough to connect a cable to the connector and transfer the image. Standard HDMI, Display Port, VGA and other wires will do.
When broadcasting from several channels and the need to switch between them, they buy a matrix switcher. Its principle of operation is simple: the sources are changed by pressing a button on the remote control or switch. The connecting cable must be selected based on the transmitter inputs – HDMI, DOP, VGA, and so on.
In addition to advertising messages and navigation, interactive display data offers a great opportunity for stores to fine-tune their marketing campaigns with targeted ads based on audience behavioral data and desires.
With regard to the current crisis, one would like to hope that life will return to normal. At this stage, the equipment can be installed with conventional displays, and eventually equipped with a content management system to simplify the creation and distribution of content, enhancing interaction with buyers.
