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

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

Yes — a high-quality outdoor LCD display can withstand direct sunlight if it passes standardized IR radiation testing, such as 800 W/m² exposure for 8 hours under IEC 60068-2-5.

Displays that meet this standard can operate reliably even in harsh outdoor environments like deserts and high-temperature urban areas.

1. Why Outdoor LCD Displays Fail Under Direct Sunlight

Outdoor environments are far more demanding than indoor conditions. The primary challenge is not brightness, but heat buildup caused by infrared (IR) radiation.

Under prolonged sun exposure, low-quality displays may experience:

• Black screen or system shutdown
• LCD panel yellowing
• Accelerated aging of internal components
• Structural deformation due to heat

Test Objective:
This test aims to validate the ability of a 55-inch high-brightness LCD display to withstand intense solar radiation and ensure long-term stable operation.

2. What Causes Overheating? Understanding IR Radiation in Sunlight

According to the IEC 60068-2-5:2018 standard, the solar spectrum at ground level is distributed as follows:

Key Insight:
Infrared radiation accounts for nearly 38% of total solar energy, making it the primary cause of overheating in outdoor displays.

Typical Solar Radiation Levels (Clear Sky)

The test condition of 800 W/m² represents a realistic and rigorous simulation covering most global outdoor environments.

3. How We Simulated Real Sunlight: 800 W/m² IR Test Setup

When selecting an outdoor LCD display, ensure:

• Verified IR radiation testing (≥800 W/m²)
• Compliance with IEC 60068-2-5
• High brightness (≥2500–3000 nits)
• Effective thermal management system
• Anti-glare or optical bonding technology

Without these, “outdoor display” may be just a marketing claim.

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

Functional coatings further enhance the performance of outdoor display glass:

• UV resistance – protects internal LCD/LED components
• Weather resistance – improves durability under heat and humidity
• Surface stability – maintains optical clarity over time

These coatings are essential for high-brightness outdoor digital signage operating 24/7.

Behind the Performance: Controlled Manufacturing Process

The performance of outdoor display glass is achieved through a strictly controlled production process:

Raw Glass → Cutting → Edge Grinding → Cleaning & Pretreatment → AG Treatment / Coating → Tempering → Laminating (Optional) → Final Inspection

Each stage ensures:

• Optical consistency
• Structural reliability
• Stable performance in outdoor environments

What This Means for Your Project

For outdoor digital signage, brightness alone is not enough.

👉 The quality of the protective glass for outdoor LCD displays and outdoor LED displays directly affects:

• Sunlight readability
• User viewing experience
• Long-term operational stability

Choosing the wrong glass solution can result in poor performance and increased maintenance costs.

How CNLC Ensures Outdoor Display Performance

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.

For years, LCD has been the dominant technology in commercial display applications—from retail signage to corporate meeting rooms.

However, this long-standing assumption is being fundamentally challenged.

A growing number of enterprises are now adopting fine-pitch LED displays powered by COB (Chip-on-Board) and MIP (Micro LED in Package) technologies. This shift is not driven by brightness improvements, but by advances in visual consistency, structural design, and long-term operational value.

Key insight: The display market is shifting from “functional adequacy” to “premium visual experience.”

What Are COB and MIP? 

COB (Chip-on-Board)

COB is a packaging technology where LED chips are directly mounted onto a PCB and encapsulated into a continuous surface layer.

Key characteristics:

• Fully integrated surface structure
• Improved impact and dust resistance
• Superior black consistency and uniformity
• High flatness suitable for seamless large displays

COB is widely used in large-format, high-end LED installations such as control rooms and corporate display walls.

MIP (Micro LED in Package)

MIP refers to a micro-packaging approach where ultra-small LED chips are first encapsulated into standardized units before being assembled into LED displays.

Key characteristics:

• Supports ultra-fine pixel pitches (P0.9, P0.7 and below)
• Higher manufacturing yield and consistency
• Better scalability for mass production of fine-pitch displays

Industry note: MIP is often considered either a sub-category or an evolution of advanced LED packaging technologies, with its core advantage being scalable ultra-fine pitch production.

Why Traditional LED Could Not Replace LCD

Before COB and MIP matured, LED technology faced clear limitations in indoor and high-precision environments:

• Large pixel pitch (typically P2.5 and above) caused visible pixelation at close viewing distances
• Exposed pixel structures reduced image smoothness
• Module gaps and surface inconsistency affected visual quality

As a result, LCD remained the preferred solution for indoor applications requiring close viewing and high image fidelity.

From Pixel Grid to Continuous Visual Surface 

COB technology fundamentally changes how LED displays are perceived.

Instead of visible pixel grids, COB creates a continuous, unified surface.

Key improvements:

• Surface flatness deviation ≤0.1mm
• Black level as low as ≤0.01 cd/m²
• Significant reduction in visual noise and brightness inconsistency

Result: LED is no longer perceived as individual light points, but as a seamless visual canvas.

From Long Distance to Close-Range Precision

MIP technology pushes LED into ultra-fine pixel pitch ranges such as P0.9 and P0.7.

This enables:

• Comfortable viewing distances below 1 meter
• Native 4K/8K resolution on large LED surfaces
• Entry into traditional LCD-dominated environments

LCD vs COB vs MIP

Key takeaway: COB enhances surface integrity, while MIP extends resolution and application scope.

Why COB and MIP Are Disrupting the LCD Market

The shift is not driven by a single parameter, but by multiple structural advantages.

1. Visual Continuity

LCD video walls always contain physical seams, even with ultra-narrow bezels.

LED displays eliminate this limitation entirely.

In premium environments, seamless visuals are now a baseline expectation.

2. Design Flexibility and Scalability

LCD is constrained by fixed panel sizes (55”, 65”, 86”).

LED can be customized into:

• Large-format video walls
• Curved or cylindrical displays
• Architectural integrations

This transforms displays from hardware into spatial design elements.

3. Long-Term Value and Maintenance Efficiency

Decision-making is increasingly based on total cost of ownership (TCO), not initial cost.

Key comparisons:

• LED lifespan: ~100,000 hours
• LCD lifespan: ~50,000 hours
• COB LED maintenance cost: up to 40% lower than LCD video walls due to modular repairability

LED provides stronger long-term operational value in high-utilization environments.

4. Real-World Brand Application Case

A luxury fashion brand implemented a 12-meter COB LED wall in its flagship retail store to replace multiple LCD panels.

Results:

• Eliminated visible bezels in storefront displays
• Increased visual engagement and dwell time
• Improved overall brand perception through immersive content delivery

This demonstrates COB LED’s advantage in high-end retail environments.

COB and MIP Application Guidance

To simplify decision-making:

COB LED is preferred for:

• Large-scale seamless installations
• Corporate headquarters
• Control centers
• Digital showrooms

Focus: stability, uniformity, large-area continuity

MIP LED is preferred for:

• Small to medium meeting rooms
• Retail counters and close-up displays
• High-resolution indoor applications
• Premium environments requiring ultra-fine pixel pitch

Focus: resolution density, close viewing comfort

Will LED Replace LCD Completely?

No.

LCD still maintains advantages in:

• Small-screen applications below 55 inches
• Cost-sensitive deployment scenarios
• Standardized indoor signage with basic requirements

However, in premium, large-scale, and design-driven environments, fine-pitch LED is rapidly becoming the dominant solution.

Conclusion

The transition from LCD to LED is not simply a technological upgrade—it represents a structural shift in display architecture and application logic.

COB and MIP technologies have enabled LED displays to overcome traditional limitations and enter markets once dominated by LCD.

The key question for businesses is no longer “LCD or LED?”
