Abstract
A billboard or other large display for displaying information has a billboard frame, an artwork layer, and either a plurality of columns of LED light plates or vertical strips of LED lights. The LED plates are small backlight panels formed in an array covering large areas suitable for standard billboards. The LED plates are secured to one another to hang from the billboard frame in separate columns. The columns are situated between the artwork layer and the billboard frame to provide a backlight for the artwork layer. The artwork layer can include two or more layers such that different artwork is displayed depending on the ambient lighting conditions as well as the backlight operation. The LEDs are preferably controlled by a controller to provide desired backlight conditions as well as to display content.
