Sansi LED: Sustainable LED Lighting and Integrated LED Display

As an important carrier for the digital upgrade of cities, Shanghai Sansi's outdoor LED display are gradually reshaping the visual expression and functional value of urban public spaces through technological innovation and scenario integration. With independent research and development at its core, this system focuses on areas such as urban image display, commercial services, and cultural dissemination, providing innovative practices for the fine governance of megacities.

Technological Breakthroughs and Scenario Innovations

1. Ultra-HD Display and Adaptation to Complex Light Environments

Sansi's outdoor LED display employ independently developed pixel-level light control technology, maintaining image clarity and color saturation under complex weather conditions such as strong sunlight, rain, and fog. For instance, the irregular bare-eye 3D screen on Nanjing Road Pedestrian Street utilizes curved seamless splicing technology to deeply integrate the building facade with displayed content, creating an immersive visual landmark that blends "technology and humanity."

2. Expanded Multi-scenario Interactive Functionality

Equipped with intelligent sensing modules, the display can perceive real-time pedestrian flow and audience dwell time, dynamically adjusting content playback strategies. Some business districts pilot the "AR virtual-real linkage" function, allowing citizens to participate in brand interactive games by scanning the screen with their mobile devices, thus precisely converting offline traffic into online communities.

3. Green Energy and Low-carbon Operation and Maintenance

The system integrates an intelligent power distribution management system, supporting flexible switching between photovoltaic energy storage and municipal electricity, ensuring round-the-clock operation while reducing energy consumption. On the maintenance side, AI fault diagnosis technology is adopted to predict module anomalies in advance and generate maintenance plans, significantly extending equipment lifespan.

Urban Services and Cultural Dissemination Running in Parallel

1. Public Information Service Platform

The display are deeply connected to the urban emergency management system, switching to disaster warning information terminals during extreme weather such as typhoons and rainstorms, and cooperating with voice broadcasting systems to provide multi-dimensional safety reminders. During daily operations, they become urban navigation windows, scrolling through convenient information such as transportation guides and cultural tourism activities.

2. Digital Expression of Regional Culture

In historic preservation areas, the display innovatively incorporate intangible cultural heritage elements, interpreting urban stories through dynamic ink paintings, micro-documentaries, and other forms. A demonstration project on the Bund even attempts to combine Shikumen building textures with digital art, creating a "readable architectural screen."

3. Upgrade of Commercial Space Value

The "time-sharing content delivery" mode developed for commercial district scenarios supports intelligent scheduling of brand advertisements, art exhibitions, public service announcements, and other content, achieving a balance between commercial value and social benefits. Some display also pilot open submission channels for citizens, driving the transformation of public spaces from "one-way dissemination" to "co-creation by all."

Future Planning and Ecological Collaboration

Shanghai Sansi's outdoor LED display plan to further establish interconnection channels with smart city management platforms, exploring collaborative applications with traffic guidance systems and environmental monitoring equipment. On the technical front, it is developing an AI-based content compliance review system to ensure that playback content complies with advertising law requirements for prohibited words and image copyright specifications.

This technological upgrade marks the transition of urban outdoor media from "information display" to "service ecology." By empowering public spaces with technology, Shanghai is providing an innovative model for the digital construction of global megacities.
