1. Display effect: The double-sided LED pole screen has a double-sided display function, which can display different content in two directions simultaneously, making dissemination more comprehensive and effective. On the other hand, single sided poster LED light pole screens can only present single sided content.
2. Visibility: The double-sided display characteristics of the double-sided LED pole screen make it more advantageous in terms of visibility, providing a larger range of displays whether facing vehicles, pedestrians, or two different audience groups. The visual range of a single sided poster LED pole screen is relatively narrow, and the display screen can only be displayed in one direction.
3. Content update: The content update of the double-sided LED light pole screen is more convenient and efficient, and can be updated in real-time through remote control or cloud management systems. The single sided poster LED light pole screen requires manual replacement to print the poster, which requires a certain amount of manpower and time cost.
4. Reliability and Durability: The LED pole screen adopts LED display technology, which has high brightness and durability, and can operate stably in various environments. There is no essential difference between double-sided LED pole screens and single-sided poster LED pole screens in this regard.
5. Application scenario: Double sided LED pole screen is suitable for displaying advertisements, publicity, and information in different directions, such as transportation hubs, commercial areas, pedestrian streets, etc. The single sided poster LED light pole screen is suitable for occasions that require a single direction display, such as indoor corridors, community streets, etc.

In summary, double-sided LED pole screens and single-sided poster LED pole screens each have different functions and application characteristics. Choosing the type that is suitable for your actual needs can better meet your promotional and advertising display goals and save budget costs.
