The demand for emerging media owners is becoming increasingly widespread, and the size of LED display screens for operation can be customized. The content includes displaying government propaganda, playing public service advertisements, fire safety propaganda and other video advertisements, image advertisements, weather forecasts, real-time information insertion, and publishing information through web platforms.
In order to reduce the manual management cost of operating multiple LED display screens, cluster control is required, and this management mode also caters to the concept of smart city application. Any one or more display screens can not only timely place advertisements, TV news (such as emergency notifications), real-time weather conditions, safety notices, but also install monitoring cameras on the screen, allowing for timely dissemination of safety information and traffic conditions, Emergencies and so on, such as someone robbing a vehicle, license plate number, suspect information can be quickly transmitted to the screen.
Looking ahead to future cluster management and control based on the Internet and cloud servers, using display screens as an interface for human-computer interaction, such as displaying current flight information, dynamic information of train numbers, and the status of unsold air/train tickets on urban transportation hub information screens; The display screen can display movie tickets from nearby cinemas that have not been sold half an hour before the movie starts, empty beds from hotels that have no guests staying that night, and promotional food from supermarkets on that day. This can not only save management costs, but also conveniently manage or update the playback content of any one of the screens.
