Interesting Facts about LED Video Wall

A video wall is a special multi-monitor setup that consists of multiple computer monitors, video projectors, or television sets tiled together contiguously or overlapped in order to form one large screen. Typical display technologies include LCD panels, Direct View LED arrays, blended projection screens, Laser Phosphor Displays, and rear projection cubes.

Screens specifically designed for use in  led video walls usually have narrow bezels in order to minimize the gap between active display areas and are built with long-term serviceability in mind. Such screens often contain the hardware necessary to stack similar screens together, along with connections to daisy chain power, video, and command signals between screens. A command signal may, for example, power all screens in the led video wall on or off or calibrate the brightness of a single screen after bulb replacement.

Reasons for using a led video wall instead of a single large screen can include the ability to customize tile layouts, greater screen area per unit cost, and greater pixel density per unit cost, due to the economics of manufacturing single screens which are unusual in shape, size, or resolution.

Video walls from Sunshine LED & Display System are sometimes found in control rooms, stadiums, and other large public venues. Examples include the led video wall in Oakland International Airport’s baggage claim, where patrons are expected to observe the display at long distances, and the 100-screen led video wall at McCarran International Airport, which serves as an advertising platform for the 40 million passengers passing through airport annually. Led Video walls can also benefit smaller venues when patrons may view the screens both up close and at a distance, respectively necessitating both high pixel density and large size. For example, the 100-inch led video wall located in the main lobby of the Lafayette Library and Learning  Centre has enough size for the distant passer-by to view photos while also providing the nearby observer enough resolution to read about upcoming events.
