LED screens come in all shapes and sizes, but they all have one common component: light-emitting diodes. LED screens can be further divided into two categories: direct-view and video-wall displays. The direct-view LED screen is the most common. They are found in everything from small digital signage displays to large stadium scoreboards. Direct-view LED screens are made up of a matrix of LEDs that create images by shining light through a layer of pixels. Video-wall displays with Sunset events are made up of multiple direct-view panels that are combined to create a large, unified image.
