What Are The Specific Applications of PoE Modules in Commercial Displays?

The application of PoE modules in commercial displays spans multiple industries, significantly enhancing deployment efficiency and display effects through simplified cabling, flexible power supply, and intelligent management. Here are specific application scenarios and typical cases:

1. Retail and Advertising Media

a. Elevator Advertising Screens and Outdoor Billboards

POE-powered LCD advertising machines transmit power and data through a single network cable, solving the problem of limited space and difficult cabling in elevators. Their energy-saving feature reduces energy consumption to half that of traditional advertising machines and supports intelligent advertising playback based on time and floor. For example, in office building elevators, promotional content for different floor merchants can be precisely targeted.

b. Interactive Screens in Smart Exhibition Halls

In digital exhibition halls, POE-powered displays can be flexibly moved without being restricted by power cords. Advertising machines in the hall can update multimedia content in real time through a remote management platform, display product details on multiple screens simultaneously, and reduce maintenance costs.

2. Transportation Hubs and Public Facilities

a. Airport or High-Speed Railway Information Screens

Industrial Ethernet PoE switches provide PoE power to LED screens in airports and high-speed railways, ensuring real-time updates of flight information, train schedules, etc. Their high-reliability design can adapt to a certain degree of extreme temperature environments.

b. Metro Advertising Screens

In metro vehicle communication systems, PoE switches power in-vehicle cameras and information screens, enabling in-car advertising playback and passenger information display. This ensures stable display during metro operation.

3. Healthcare Industry

a. Hospital Guidance Screens

POE-powered advertising machines are deployed in hospital waiting areas to play health education videos and department navigation information. PoE technology simplifies cabling and reduces construction difficulty in hospital environments, while supporting intelligent content push based on department and time.

b. Ward Information Screens

POE-powered bedside interaction terminals are installed at the head of hospital beds to display patient information, medical orders, and health guidance. Medical staff can update content in real time through a remote management platform, improving nursing efficiency. The intelligent interaction bedside screen integrates functions such as call for help and fee inquiry, optimizing the patient experience.

4. Education Field

a. Smart Classroom Electronic Whiteboards

In classroom feedback systems, PoE modules connect 4K teaching observation cameras and array microphones to capture teacher images and recognize speech. PoE power supply simplifies classroom cabling and supports multi-device interaction, such as real-time display of student answers on interactive smart boards.

b. Multimedia Classroom Displays

PoE-powered displays can be used for teaching material presentation and interaction. PoE technology reduces the need for strong electrical cabling in classrooms and lowers the risk of electricity use.

5. Hotel and Accommodation Industry

a. Guest Room Information Systems

Smart TVs or information screens in hotel rooms are powered by PoE to display welcome messages, room service menus, and local tourism recommendations. For example, hotels use PoE switches to power wireless APs and surveillance cameras, while supporting remote management of guest room displays to enhance the check-in experience.

b. Lobby Interactive Screens

Touch screens in hotel lobbies use PoE technology for power and data transmission, providing self-check-in, map navigation, and other functions. PoE power supply eliminates the need for additional power cords, making equipment installation more flexible and adaptable to frequent layout adjustments in the lobby.

6. Enterprise Conferences and Offices

a. Conference Room Touch Screens

PoE-powered wireless touch screens serve as conference room controllers, enabling one-click initiation of video conferences, content sharing, and device control. Their PoE connection simplifies installation processes, especially suitable for centralized management in medium and large conference rooms.

b. Video Walls and Digital Signage

PoE-powered video walls in enterprise office areas are synchronized through PoE switches, achieving simultaneous display of multiple screens. For example, during the renovation of business halls, PoE technology not only powers the LED lighting control system and security surveillance but also supports the real-time data display on the information screens in the hall, enhancing office efficiency.

7. Catering Industry

1. Electronic Menu Boards

The electronic menu screens in restaurants are powered by PoE modules, allowing for real-time updates of dish pictures, prices, and promotional information. PoE technology reduces the complexity of wiring in the kitchen and dining area, and also supports remote management, facilitating the unified update of menus in chain restaurants.

2. Self-service Ordering Screens

The self-service ordering machines in fast food restaurants are powered by PoE, integrating payment functions and order status displays. PoE technology ensures the stable operation of the devices in high-traffic environments and simplifies the maintenance process.

8. Outdoor and Special Environments

1. Tourist Information Screens

The information display screens in outdoor scenic spots are powered by PoE modules and feature waterproof and lightning protection designs (such as IP65 protection level), enabling normal display of maps, scenic spot introductions, and real-time visitor flow data in rainy and snowy weather.

2. Intelligent Traffic Navigation Screens

The variable message signs on highways are powered by PoE, providing real-time updates on road conditions, speed limits, and accident warnings. PoE technology reduces the cost of outdoor wiring and supports seamless integration with traffic management systems.

Technical Advantages of PoE Power Supply and Selection Suggestions for PoE Modules

- Power Supply Standard Compatibility: For low-power displays (such as those under 30W), IEEE 802.3af/at standards can be selected. For high-power devices (such as touch screens and outdoor screens), IEEE 802.3bt (PoE++) should be adopted.

- Network Stability: Use Cat 6 or higher specification network cables and combine QoS configuration to prioritize video data streams and avoid lag.

- Intelligent Management: Centralized monitoring of display status through an IoT platform enables remote content updates, fault diagnosis, and energy consumption optimization.

The PoE module, with its feature of "solving power supply and data transmission with one network cable", has become a core technology for the intelligent upgrade of commercial displays. Its application scenarios are still expanding with the development of the Internet of Things and 5G technology.
