Used LED Video Screens

LED Screens are used in concerts to produce a video wall or concert video screen, so that the musicians and performers can be shown close up, and also for displaying background visuals during a performance. This type of visual display system is essentially a large number of LED screens which are tiled together or overlapped in a way so that they produce a much larger screen. Also called a video tile, LED screens will have extremely narrow bezels (the part which surrounds the LED screens), so that the display is not impacted too badly by having large gaps appear between each tile. Many concert planners prefer using LED screens to one large screen as they offer a number of advantages, including a customized layout, greater pixel density and a greater screen area for the cost, as manufacturing unusually large screens can be prohibitively expensive. LED screens use something called light-emitting diodes to illuminate the video screen. Two different types of panel are used in LED screens â?? discrete LEDs and surface mounted panels. Most types of outdoor LED video screen and indoor LED video screen use discrete LEDs, which are made up of a cluster of blue, green and red diodes. This cluster of diodes forms just one pixel in the LED screen, and so many hundreds of diodes are used, with the pixels being spaced out evenly across the entire screen. This combination of color clusters enables every color in the light spectrum to be replicated on LED screens.
