Digital billboards are electronic image displays that present multiple static advertisements on a rotating basis. Larger outdoor billboards appear alongside roadways, while smaller indoor billboards appear in entertainment venues, malls, etc. Outdoor digital billboards use the same dimensions as standard, static billboards. The screen surface comes in standard 1sqm panels and because they are modular, screen surfaces can be build to any size. When a curved screen is required we follow the same modular stacking principals. These billboards use hundreds of light-emitting diodes (LEDs) to create an image. Larger indoor digital billboards use the same LED-based displays as outdoor digital billboards. Smaller indoor digital billboards may use liquid crystal display (LCD) video screens, similar to computer monitors and televisions. Digital billboards may be mounted on a post or wall using a steel structure or “enclosure” built for the location and screen system.
