Essential Considerations for Constructing a Video Wall Abstract

The ground on which the video wall is installed must be flat, solid, and possess a high bearing capacity. The cabinet base should be in direct contact with the anti - static floor. This is crucial as an uneven or weak ground can cause long - term deformation, which may lead to structural instability of the video wall and damage to the display units.

Computers in the control room should face the video wall directly. An appropriate distance between the computers and the video wall is necessary. This setup allows operators to easily observe and operate the video wall. Moreover, it facilitates color adjustment and debugging, ensuring accurate color representation and high - quality visuals on the screen.

Built - in downlights are recommended. They should be placed approximately 3 meters away from the screen and should not shine directly on it. Direct light can cause glare, which significantly impairs the viewing experience. In rooms with large windows, light - blocking curtains are a must to prevent sunlight from creating similar glare problems.

Strong and weak current cables should be laid separately to avoid electromagnetic interference. The cables should be fixed on the ground using wiring channels, and the wiring distance should be minimized. Shorter wiring distances reduce signal attenuation and the risk of interference. For anti - static floors, holes need to be drilled at the cable outlets to ensure proper and safe wiring.

The system power supply should be AC220V ± 5%. A three - pronged socket with a protective grounding wire is required to prevent electrical hazards. All components of the splicing system and related equipment should be powered by the same phase to avoid phase - related issues. Additionally, a UPS (Uninterruptible Power Supply) is essential to provide continuous power in case of a power outage, protecting the system from damage and data loss.

A maintenance passage of about 0.6 meters should be reserved behind the splicing system to allow easy access for maintenance and repair. The working environment temperature should be maintained at 23°C ± 5°C, and the humidity should range from 20% - 80%. Consistent temperature and humidity levels both in front of and behind the video wall are important. Regular room cleaning is necessary to prevent dust accumulation, which can affect the performance of the video wall.

Without a splicing controller, an LCD splicing screen is merely a basic display device. It cannot support advanced features such as picture - in - picture and window roaming. A video wall controller is vital for enabling these functions and maximizing the potential of the video wall.

Building a video wall is a multi - faceted process that requires meticulous attention to various factors. From the installation ground to the control room, lighting, wiring, power supply, and system environment, each aspect is integral to the proper functioning and performance of the video wall. The video wall controller also plays a crucial role in unlocking advanced display capabilities. Overlooking any of these key issues can lead to sub - optimal performance, system malfunctions, and even damage to the equipment.
