The global rollout of 5G networks has moved beyond early deployment into a phase of dense, high-capacity infrastructure expansion. Across North America, Europe, South Korea, Japan, and increasingly in South Africa and the broader African continent, mobile network operators are densifying their mid-band and high-band deployments, upgrading backhaul links, and preparing the groundwork for what comes next: 6G research and early standardization, expected to culminate in commercial deployments around 2030.

For the connectivity components industry, this sustained infrastructure wave translates into sustained demand — and significant opportunity for engineers and procurement teams who understand where the requirements are heading.

The Numbers Behind the Expansion

What 5G Infrastructure Actually Requires from Connectors

5G radio access networks (RAN) are fundamentally different from their 4G predecessors in ways that directly affect connectivity component selection:

Higher port density at the base station: 5G Massive MIMO antennas integrate dozens to hundreds of antenna elements, and the radio units that feed them require high-density Ethernet interfaces. This drives demand for multi-port RJ45 ICM connectors in 1×N and 2×N configurations, as well as SFP/SFP+ cage connectors for fronthaul and midhaul fiber links.

Wider deployment of 10G Ethernet in backhaul: As 5G sites push more traffic, the backhaul link from the base station to the core network must scale accordingly. 10GBase-T copper and 10G SFP+ fiber are both seeing strong adoption, particularly for urban macro sites and enterprise small cells where fiber may not be available to every location. Vitalconn's 10G ICM RJ45 and SFP+ cage portfolio is directly aligned to this requirement.

Extended temperature and ruggedization: Outdoor base station equipment operates in environments ranging from arctic cold to tropical heat. Industrial-grade connectors rated for -40°C to +85°C, with robust through-hole mounting and high-vibration tolerance, are essential — not optional — for radio unit designs.

PoE for small cells and indoor units: Many 5G indoor small cells and enterprise Distributed Antenna System (DAS) units are powered over Ethernet, simplifying installation by eliminating a separate power cable run. PoE++ (802.3bt) support at the ICM level is increasingly specified by small cell OEM designers.

Data Centers: The Other Half of the 5G Demand Story

5G is not only a RAN story. The compute and networking infrastructure that supports 5G — Mobile Edge Computing (MEC) nodes, cloud-native core network functions, and the hyperscale data centers that underpin them — all represent massive connector demand in their own right.

Hyperscale data center construction spending hit a record high in 2025, driven by AI workloads as much as by 5G core network virtualization. Inside these facilities, the transition from 10G and 25G to 100G and 400G port speeds is well underway, with SFP28 (25G), QSFP28 (100G), and QSFP-DD (400G) cage connectors all in high demand. Vitalconn's SFP/SFP+ and QSFP28 cage portfolio addresses the 1G-to-28G segment directly, with signal integrity simulation support available to help customers validate their PCB layouts.

At the top-of-rack switch and server NIC level, 10GBase-T copper ports remain highly relevant for cost-sensitive server connectivity, keeping 10G ICM RJ45 demand robust even as optical speeds scale upward at the core.

Japan and Korea: Leading the Charge on 6G R&D

While 5G deployment continues globally, Japan and South Korea are already heavily investing in 6G research. Japan's Ministry of Internal Affairs and Communications has committed to having 6G technology ready for commercialization by 2030, with NTT DOCOMO, NEC, and Fujitsu all active in 6G testbed development. South Korea's government has similarly earmarked substantial R&D funding, with Samsung and LG Electronics prominent among the contributors.

For connectivity component suppliers, this means engineering engagement with 6G test equipment and early prototype hardware is already beginning. The frequency ranges under consideration for 6G — including upper mid-band (7–24 GHz) and sub-terahertz bands — will require connectors and transformers with performance characteristics that push beyond today's 10G Ethernet standards. Early engagement with R&D programs in Japan and Korea is a strategic priority for suppliers looking to be designed into the next generation of infrastructure hardware.

What This Means for Procurement Teams

The sustained infrastructure build-out across 5G, data center, and early 6G R&D creates several practical implications for procurement and supply chain teams:

• Long-term sourcing relationships matter. Infrastructure programs span years, not quarters. Partnering with a connector supplier who can commit to multi-year supply continuity — with consistent quality and part number stability — reduces re-qualification risk.
• Customization capability is a differentiator. OEMs designing for specific regional markets (a South African operator's backhaul specification may differ from a Japanese carrier's) need connector suppliers who can accommodate custom configurations without minimum order quantities that make prototyping unaffordable.
• Documentation and compliance are non-negotiable. RoHS, REACH, UL, and IEEE 802.3 compliance documentation must be readily available. Any delays in sourcing compliance paperwork can hold up product certification and delay market entry.

In an era defined by exponential data growth, cloud computing, and the proliferation of edge devices, data centers are under unprecedented pressure to deliver faster, more reliable, and scalable connectivity. As organizations migrate to virtualized environments, adopt unified networking, and embrace data-intensive technologies like AI and big data analytics, the limitations of traditional 1GBASE-T infrastructure have become increasingly apparent. Enter 10GBASE-T: a game-changing Ethernet standard that is reshaping the future of high-speed connectivity and redefining how data centers operate. At Vitalconn (www.vitalconn.com), we’re at the forefront of this transformation, empowering businesses with the tools and solutions to unlock the full potential of 10GBASE-T.

The Need for Speed: Why Data Centers Are Outgrowing 1GBASE-T

For years, 1GBASE-T has been the workhorse of data center connectivity, providing adequate bandwidth for basic server-to-switch and switch-to-storage communications. However, the rise of server consolidation through virtualization has fundamentally changed network I/O demands—combining the network needs of multiple physical machines, live migration, and background services onto a single server strains 1GBASE-T’s capabilities to the breaking point. Add to this the growing adoption of unified networking, which uses a single Ethernet network for both data and storage traffic, and 1GBASE-T quickly becomes a bottleneck, forcing organizations to deploy multiple gigabit connections to keep up with peak-period demands.

Data centers today require a connectivity solution that can handle higher bandwidth, support more devices, and reduce complexity—all while remaining cost-effective. 10GBASE-T addresses these challenges head-on, delivering 10x the bandwidth of 1GBASE-T (10Gbps) and eliminating the need for multiple parallel connections. This shift isn’t just about speed; it’s about building a future-proof infrastructure that can adapt to evolving business needs.

10GBASE-T: The Game-Changer for Data Center Connectivity

Defined by the IEEE 802.3an-2006 standard, 10GBASE-T is a 10 Gigabit Ethernet (10GbE) technology that uses twisted-pair copper cabling—most commonly Cat6a or Cat7—to deliver 10Gbps speeds over distances of up to 100 meters. Unlike other 10GbE solutions such as SFP+ fiber or direct attach copper (DAC), 10GBASE-T offers unique advantages that make it ideal for widespread data center deployment:

1. Cost-Effective Scalability

Fiber optic cables and SFP+ modules are expensive, making them impractical for broad deployment across the entire data center. SFP+ DAC, while more affordable, is limited to a maximum reach of 7 meters and requires full infrastructure upgrades. 10GBASE-T, by contrast, leverages existing copper cabling investments—many data centers already have Cat6 or Cat6a cabling in place, which can support 10GBASE-T with minimal upgrades (Cat6 supports up to 45 meters, while Cat6a extends to 100 meters). This compatibility eliminates the need for costly cable replacements, reducing upfront deployment costs and accelerating time-to-value.

2. Simplified Infrastructure & Management

10GBASE-T consolidates multiple 1GBASE-T ports into a single 10Gbps connection, streamlining network architecture and reducing complexity. With fewer cables, switches, and ports to manage, data center administrators can reduce maintenance overhead, minimize human error, and improve overall network reliability. Additionally, 10GBASE-T uses standard RJ45 connectors, which are familiar to IT teams and compatible with existing networking tools—eliminating the need for specialized training or equipment.

3. Improved Power Efficiency & Performance

Early concerns about 10GBASE-T’s power consumption have been addressed by advances in manufacturing processes, making modern 10GBASE-T transceivers far more energy-efficient than their predecessors. Today’s 10GBASE-T solutions consume less power per gigabit than many fiber-based alternatives, reducing data center energy costs and carbon footprints. Furthermore, 10GBASE-T delivers low latency (well within the requirements of most enterprise applications) and full-duplex operation, ensuring smooth, uninterrupted performance for data-intensive workloads like virtualization, cloud computing, and real-time analytics.

4. Versatility Across Use Cases

10GBASE-T isn’t limited to server-to-switch connectivity—it supports a wide range of data center use cases, including top-of-rack (ToR) switching, workgroup aggregation, and storage area network (SAN) connectivity via Fibre Channel over Ethernet (FCoE). Its 100-meter reach makes it suitable for large data centers, while its compatibility with legacy infrastructure ensures seamless integration with existing 1GBASE-T devices through backward compatibility. This versatility makes 10GBASE-T a one-size-fits-all solution for modern data centers.

If you design or manufacture Ethernet-enabled devices — industrial switches, routers, IoT gateways, or smart home controllers — you've almost certainly encountered the term ICM RJ45 magnetic jack. But what exactly is it? How does it differ from a standard RJ45 connector? And why do so many engineers insist on using one?

In this guide, we'll break down the ICM RJ45 magnetic jack from the ground up: its architecture, specifications, selection criteria, and real-world applications.

What Does "ICM" Stand For?

ICM stands for Integrated Connector Module. An ICM RJ45 magnetic jack is a single, compact component that combines three critical Ethernet circuit functions into one package:

1. RJ45 Receptacle (Jack): The physical interface for plugging in an Ethernet cable.
2. Magnetic Transformer (LAN Transformer): Provides electrical isolation, impedance matching, and common-mode noise rejection between the Ethernet PHY transceiver and the cable.
3. Common-Mode Choke (CMC): Suppresses electromagnetic interference (EMI) on both transmit and receive pairs.

Instead of sourcing and mounting a separate RJ45 jack, a LAN transformer, and discrete chokes on your PCB, an ICM integrates all three into a single through-hole or surface-mount module.

With the rapid development of fine-pitch LED technology, COB (Chip on Board) is regarded by many as the future of the LED industry due to its higher contrast, better flatness, and more delicate image quality.
While COB has demonstrated impressive visual performance indoors, it faces multiple stringent challenges when deployed outdoors. Many clients, engineers, and industry peers often ask:

Why is it difficult for COB LED to operate stably outdoors for the long term?

In fact, this is not due to limitations of COB technology itself. The outdoor environment imposes extremely high requirements on COB, and traditional improvements or simply adding air conditioning are not sufficient. Heat accumulation, UV aging, rain and humidity, dust, and day-night temperature fluctuations are all “multiple challenges” that COB faces outdoors.

The industry has long lacked COB products truly designed for outdoor environments, and CNLC’s air-conditioned COB P1.25 offers a complete, system-level solution, making outdoor COB operation possible.

Outdoor COB Challenges: It’s Not Just About Heat

High-density chips + full encapsulation → Heat dissipation difficulties
COB mounts a large number of LED chips directly on the PCB and covers them with full-surface encapsulation. Traditional fans or passive cooling are far from sufficient under strong sunlight. Long-term operation can lead to brightness decay, color shifts, and chip aging.

UV radiation → Encapsulation aging
The encapsulation can yellow and become brittle under sunlight, reducing light transmittance and affecting overall screen color uniformity. SMD screens, with protective housings, are better suited for outdoor use as they resist UV radiation more effectively.

Humidity, dust, temperature fluctuations → Encapsulation damage
If micro-cracks appear in the full-surface COB encapsulation, moisture can penetrate and affect chip stability. Ordinary glass covers or added waterproof strips can only partially mitigate these issues and cannot fundamentally solve the problem.

Summary: The challenges for outdoor COB are multi-dimensional, not limited to heat or protection alone.

CNLC Air-Conditioned COB P1.25: System-Level Design Enables Outdoor COB

CNLC’s innovation lies in a fully systemized design:

• Built-in air conditioning + optimized internal airflow: Maintains the cabinet interior at around 40°C, allowing chips to operate in a stable environment even when outdoor temperatures range from 0–60°C.

• 99% UV-blocking optical glass + IK10 impact resistance: Blocks ultraviolet light, enhances hardness, reduces glare, and withstands outdoor impacts.

• IP66 fully enclosed cabinet: Keeps electronic components shielded from the air, combined with air-conditioned circulation for true protection against water, dust, and humidity.

• 3500 nits high brightness: Solves traditional COB brightness deficiencies, ensuring clear visibility under direct sunlight.

This is not simply “adding air conditioning.” It is a full-chain optimization from PCB encapsulation to cabinet structure, thermal management, optical glass, and protection rating, allowing COB to achieve long-term, stable outdoor operation. Previously, the industry often said: “COB cannot be used outdoors.” Now we can say:

COB is not inherently unsuitable for outdoor use; the problem has been the lack of a system-level, outdoor-focused solution.

CNLC’s air-conditioned COB P1.25 redefines the possibilities of outdoor COB through full-chain optimization from chip encapsulation to cabinet structure, thermal management, optical glass, and protection rating.
It is not simply an indoor screen placed outdoors; it is a true technological reconstruction—each component is carefully designed to ensure COB can operate stably outdoors over the long term.

Global Debut at ISE 2026 – Experience It Firsthand

As a milestone achievement of CNLC’s years of R&D, the air-conditioned COB LED P1.25 will officially debut at ISE 2026.
This will mark the first time the industry sees a COB product genuinely capable of long-term stable outdoor operation, representing an important moment as CNLC and global partners explore the future of outdoor LED displays.

We sincerely invite you to visit ISE 2026, experience this breakthrough technology firsthand, and witness the future possibilities of outdoor COB.

Outdoor digital signage, bus shelter displays, and other public-facing display systems are now exposed to increasingly demanding environments: intense sunlight, continuous high temperatures, 24/7 operation, and strict public safety requirements.

Under these conditions, traditional glass can no longer meet the needs of brightness transmission, heat management, safety, and long-term stability.

To address these real-world challenges, CNLC has developed a high-performance optical laminated glass solution specifically engineered for Outdoor Digital Signage and Bus Shelter Displays. By enhancing light transmission, reducing heat ingress, and improving safety performance, this optical glass provides a more reliable protective layer for any high-brightness outdoor LCD or LED display.

1.Why Outdoor Displays Increasingly Depend on Optical-Grade Laminated Glass

①. Higher Brightness Requires Higher Light Transmission

Outdoor displays typically reach 3000–7000 nits.
If the cover glass has low transmittance, the actual perceived brightness will drop dramatically, reducing daylight visibility—a critical factor for high-brightness outdoor screens.

②. More Extreme Thermal Conditions Demand Better Heat Control

Infrared radiation accelerates internal heat buildup, causing:

• brightness degradation

• component aging

• reduced operational stability

IR-cut laminated glass helps block external heat, enabling the display system to operate within a safer temperature range.

③. Public Safety Standards Continue to Rise

Bus shelters, transportation hubs, and roadside digital signage require:

• anti-shatter performance

• explosion-proof structure

• safety glass certified for public environments

High-strength laminated safety glass has therefore become the industry standard.

2. CNLC High-Performance Optical Laminated Glass: Structure & Functional Layers

Ultra-white Glass / AG / AR + PVB + IR + PVB + Ultra-white Glass / AG / AR

• Ultra-white Glass

Provides extremely high visible light transmittance, offering a clean and accurate visual base for outdoor LCD and LED displays.

• AG (Anti-Glare) Coating

Reduces surface reflections and improves display readability under strong sunlight.

• AR (Anti-Reflective) Coating

Further boosts light transmission, delivering clearer, brighter, and more vibrant images.

• PVB Interlayers

Adds impact resistance, anti-shatter performance, and acoustic damping—essential for public installations such as outdoor kiosks and Bus Shelter Displays.

• IR Thermal Insulation Layer (IR 15% Transmission)

Effectively blocks infrared heat, lowering internal temperature load and enhancing long-term display stability.

3. Core Performance Advantages (UV 1% / IR 15% / VLT 91%)

①. Higher Brightness Utilization (VLT 91%)

The high transmittance minimizes brightness loss, allowing the display to deliver:

• higher visibility

• optimized color performance

• superior sunlight readability

②. Better Visibility in Direct Sunlight (AG + AR)

The dual anti-glare and anti-reflective system enhances visual contrast and reduces unwanted reflections—key to premium Outdoor Digital Signage.

③. Reduced Thermal Load (IR 15%)

The IR layer:

• lowers external heat ingress

• reduces internal temperature rise

• supports more stable performance in hot climates

While optical laminated glass greatly assists in thermal control, overall thermal stability still depends on:

• display module heat output

• internal airflow design

• cooling/ventilation system

• enclosure structure

Thus, high-performance glass is a critical component, but it must work in synergy with the full system design.

④. Enhanced Safety & Durability (PVB Laminated Structure)

The laminated structure prevents glass fragments from scattering upon breakage, providing the safety level required for:

• public transportation displays

• roadside advertising

• urban outdoor applications

4. Ideal Application Scenarios: Outdoor Digital Signage & Bus Shelter Displays

①. Outdoor Digital Signage

High brightness + direct sunlight + 24/7 operation
→ Requires high-light-transmission and IR-cut laminated glass to maintain image clarity and long-term stability.

②. Bus Shelter Displays

High foot traffic + prolonged exposure to sunlight + strict safety requirements
→ Laminated safety glass becomes essential for durability and public protection.

Conclusion

High-performance optical laminated glass has become an essential component in premium outdoor display systems. It significantly enhances light transmission, improves image clarity, reduces thermal load, and ensures higher safety levels.

However, achieving true all-weather stability requires synergy between:

• the optical glass

• the display module

• the cooling and ventilation system

• the entire structural design of the outdoor enclosure

With its Ultra-white + AG/AR + PVB + IR + PVB structure, CNLC’s optical laminated glass is rapidly becoming the industry-standard choice for high-end Outdoor Digital Signage and Bus Shelter Display solutions.

Outdoor digital signage systems—whether LED advertising displays or high-brightness outdoor LCD displays—must operate reliably in demanding environments. These displays are often installed in streets, transportation hubs, commercial districts, and roadside advertising locations where they are exposed to high temperatures, rain, humidity, dust, and continuous 24/7 operation.

When selecting outdoor digital signage equipment, buyers often focus on specifications such as brightness, screen size, or pixel pitch. However, one critical factor that is sometimes overlooked is the structural cabinet of the display system.The cabinet forms the structural foundation of the entire display. It houses internal electronic components, protects the system from external environmental factors, and plays an important role in heat dissipation, structural stability, and overall equipment lifespan.

In the outdoor digital signage industry, two cabinet materials are commonly used:

• Aluminum structural cabinets

• Steel or sheet-metal cabinets

Understanding the differences between these materials can help system integrators, project developers, and advertising operators choose a more reliable outdoor display solution.

Key Differences Between Aluminum and Steel Cabinets

The cabinet material directly affects the thermal performance, corrosion resistance, installation efficiency, and long-term durability of outdoor digital signage systems.

Because of these advantages, aluminum cabinet structures are increasingly becoming the preferred choice for high-end outdoor digital signage equipment.

Why Outdoor Displays Require Aluminum Structures

Compared with indoor displays, outdoor digital signage must operate under much harsher environmental conditions.

Typical challenges include:

• High ambient temperatures

• Long periods of direct sunlight

• Rain and humidity

• Dust and air pollution

• Salt corrosion in coastal areas

• Continuous 24/7 operation

If the cabinet material cannot effectively dissipate heat or resist corrosion, internal electronic components may experience overheating, shortened lifespan, or unstable system performance.

Thanks to its high thermal conductivity, lightweight structure, and excellent corrosion resistance, aluminum performs significantly better in outdoor environments. As a result, aluminum cabinets are increasingly used in modern outdoor digital signage systems.

Aluminum Cabinets in Outdoor LED and LCD Displays

Both outdoor LED displays and high-brightness outdoor LCD digital signage generate significant heat during operation while also being exposed to solar radiation and environmental temperature changes.

Using an aluminum cabinet structure can improve the overall performance of the display system. Because aluminum conducts heat efficiently, it can transfer and release internal heat more quickly, helping LED modules or LCD panels maintain stable operating temperatures.

This structural approach improves system reliability and helps reduce problems caused by overheating, such as brightness degradation, color shifts, or component damage, ultimately extending the overall lifespan of the display equipment.

FAQ: Outdoor Digital Signage Cabinet Materials

What is the best cabinet material for outdoor digital signage?

Aluminum cabinets are widely considered one of the best structural materials for outdoor digital signage because they provide excellent heat dissipation, corrosion resistance, and lightweight structural advantages compared with traditional steel cabinets.

Why is heat dissipation important for outdoor displays?

Outdoor LED displays and high-brightness LCD panels generate significant heat during operation. Efficient heat dissipation helps maintain stable operating temperatures and prevents brightness degradation, color shifts, or component failure.

Are aluminum cabinets more durable than steel cabinets?

Yes. Aluminum naturally forms a protective oxide layer that resists corrosion, making it more suitable for humid, rainy, or coastal environments where steel structures may rust over time.

Do aluminum cabinets reduce installation costs?

Because aluminum structures are significantly lighter than steel, they simplify transportation and installation. This can help reduce overall project costs, especially for large outdoor display installations.

When Outdoor Digital Signage Becomes Hard to Read

When installing an outdoor digital signage display, many projects face the same challenge:

👉 The screen looks clear indoors — but becomes difficult to read under direct sunlight.

In many cases, the issue isn’t the display panel itself, but the protective glass used in outdoor LCD displays and outdoor LED displays.

This is where AG (anti-glare) glass plays a critical role in achieving sunlight readable displays. However, not all anti-glare glass is suitable for demanding outdoor environments.

In this article, we’ll explore how outdoor display glass is engineered, and why it directly impacts the performance of outdoor digital signage, outdoor kiosks, and smart city display systems.

What Is Outdoor-Grade AG Glass?

Compared with standard anti-glare glass, outdoor display glass for digital signage must achieve a balance between multiple key properties:

• Anti-glare performance
• High light transmittance
• Mechanical strength
• Long-term environmental stability

If these factors are not properly optimized, common issues include:

• Poor visibility under sunlight
• Reduced contrast and image haze
• Shortened lifespan of outdoor display systems

Core Technology: AG Surface Treatment for Sunlight Readability

The key to anti-glare glass for outdoor displays lies in its surface structure.

Through controlled chemical etching or coating processes, a micro-diffused surface layer is created, which:

• Reduces direct reflection
• Eliminates mirror-like glare
• Maintains clear image visibility

For high-brightness outdoor LCD displays and outdoor LED displays, this step is essential to achieve sunlight readable display performance under strong sunlight.

High Transmittance with Optical Control

In outdoor environments, optical performance directly affects brightness, energy efficiency, and thermal behavior of the display enclosure.

High-performance outdoor display glass typically achieves:

• >91% light transmittance – Ensures maximum brightness output for outdoor LCD displays
• IR transmission ≤15% – Reduces heat buildup, improving thermal management
• UV transmission ≤1% – Minimizes long-term degradation of internal display components

Strength & Safety: Tempering and IK10 Impact Resistance

After surface treatment, the glass must undergo a tempering process to meet outdoor durability requirements.

Tempered glass, combined with structural design, provides enhanced performance for vandal-resistant outdoor digital signage displays.

This significantly improves:

• Impact resistance
• Structural stability
• Operational safety

Enhanced Solutions for Harsh Outdoor Environments

In demanding outdoor environments, single-layer tempered AG glass may not be sufficient. Additional enhancements are often required for outdoor digital signage systems.

Laminated Glass: Improved Safety & Anti-Vandal Protection

Laminated glass consists of multiple glass layers bonded with a PVB interlayer.

Even when broken, fragments remain attached, making it ideal for vandal-resistant outdoor displays.

This structure provides:

• Enhanced safety (anti-shatter protection)
• Higher impact resistance
• Anti-vandalism performance

Functional Coatings: Weather Resistance & Long-Term Stability

In the design of large-scale outdoor LED billboards, structural safety is always one of the most critical considerations.
Due to their large display area and significant wind-exposed surface, wind load often becomes the decisive factor in whether a structural design succeeds or fails.

To ensure stable and safe operation in long-term outdoor environments, standardized wind load and structural calculations are an essential engineering verification, not a formal or symbolic process.

Why Do LED Billboards Have Higher Wind Load Requirements?

Compared with general outdoor display products, LED billboards typically have the following characteristics:

• Large display area directly exposed to wind forces

• Higher installation heights, resulting in significantly increased wind pressure

• Long-term operation, usually running 24/7 continuously

Under strong wind conditions, wind load simultaneously acts on:

• The LED display surface

• The internal steel support structure

• The aluminum profile frame system

• Columns, base structures, and foundation connections

If the structural design is insufficient, even a normally functioning display may pose potential safety risks.

Composite Structural Design: Steel–Aluminum Collaboration for Structural Safety

Our outdoor LED billboards adopt a composite structural design that deeply integrates steel structures and aluminum profiles.
These two materials are not arranged in a “primary–secondary” relationship; instead, each performs its specific role while working together to form a stable and reliable structural system:

• Steel structures serve as the primary load-bearing framework, applied to columns, rear frames, and key supporting members. With their superior strength and stiffness, they resist the main wind-induced loads and form the structural safety foundation.

• Aluminum profile structures are essential components of the display body, responsible for frame formation, module fixation, and load transfer.
  They ensure dimensional accuracy and structural consistency of the screen while optimizing overall weight through lightweight design. At the same time, wind loads acting on the display surface are evenly transferred to the steel structure, forming a complete “load reception – transmission – bearing” force path.

This composite structural solution achieves an optimal balance among strength, stiffness, durability, and overall stability, making it well suited for demanding outdoor wind environments.

Wind Load Structural Calculations Based on Design Codes

All structural calculations are conducted in accordance with Code for Design of Building Structures Loads (GB 50009-2012) and referenced against Code for Seismic Design of Buildings (GB 50011-2010).
Conservative engineering parameters are applied throughout the analysis to ensure the reliability and safety of the calculation results.

Key Design Parameters (Example)

• Display area: 12 m²

• Installation height: 10 m (structural calculation height z = 10 m)

• Basic wind pressure: 0.27 kPa

• Adjusted design wind pressure (standard wind load value): 0.36 kPa

Load Combination and Unfavorable Condition Verification

To simulate the most unfavorable operating conditions, the following load combination is adopted:

1.3D + 1.5W + 0.7E
(D = Dead load, W = Wind load, E = Seismic load)

Under this condition:

• Maximum load perpendicular to the display surface: 3.97 kPa

Structural Deformation Verification

• Maximum structural deformation: 40.3 mm

• Code-allowed deformation limit: 46 mm

The results show that structural deformation is strictly controlled within allowable limits, effectively preventing issues such as module loosening or display abnormalities caused by excessive deformation, thereby ensuring long-term operational stability.

Structural Strength Verification

Steel Structure

• Material: Q235B structural steel

• Maximum calculated stress of key steel members: ≈ 200 MPa
  (lower than the steel design strength of 215 MPa)

The results fully comply with code requirements, confirming reliable structural strength.

Aluminum Profile Structure

As a core component responsible for load transfer and structural formation, the aluminum profile system undergoes rigorous multi-dimensional verification:

• Collaborative load-sharing design with steel structures, ensuring uniform wind load distribution and avoiding local stress concentration

• Independent strength verification at critical load points such as module connections and corner supports

• Synchronized deformation control, ensuring consistent deformation behavior between aluminum and steel structures

• Connection stability verification, including pull-out and shear checks for aluminum–steel and aluminum–module connections

These validations ensure that aluminum profiles not only provide lightweight and precise structural formation but also maintain sufficient safety margins within the overall structural system.

Complete Structural Verification from Display to Foundation

The calculation scope covers all critical structural elements, achieving comprehensive safety verification from the display body to the foundation:

• Load analysis of columns and base structures

• Tensile and shear verification of anchor bolts

• Verification of anchorage length and foundation bearing capacity

This full-chain validation ensures structural stability even under extreme wind and seismic conditions.

Applicable to the Entire Range of Outdoor Display Products

Although this article uses an outdoor LED billboard as an example, the same structural design principles and wind load calculation methodology apply to a full range of outdoor display products, including:

• Outdoor LED Billboards

• Outdoor LED Totems

• Outdoor LED Mupi Displays

• Outdoor LCD Digital Signage Totems

• Drive-Thru Digital Menu Boards

• Smart City Display Systems

Corresponding wind load calculation reports and structural documentation can be provided based on specific project requirements.

Engineering Validation for Long-Term Reliable Operation

In actual engineering implementation, we have completed multiple code-compliant wind load and structural calculations for various outdoor display structures, including outdoor LED billboards and outdoor LCD totems / digital signage systems.
This accumulated engineering experience has been standardized and applied across different product platforms to guide structural design and safety verification, ensuring long-term reliability under diverse installation conditions.

Wind load structural calculation is not a formality—it is a real engineering validation of safety, stability, and long-term durability.
Whether through the core load-bearing role of steel structures or the collaborative contribution of aluminum profiles, all designs adhere to a “safety-first” principle, making structural stability a fundamental standard across all our outdoor display solutions.
