In indoor LED display projects, the choice of module type not only affects image quality but also directly impacts equipment stability, durability, and long-term maintenance costs. Differences in packaging technology are clearly reflected in protection performance, maintenance methods, and overall reliability.
Currently, the two most widely used product types on the market are standard modules (IF-2S, IF-3S) and GOB modules (IF-2G, IF-3G). The former focuses on high brightness and flexible maintenance, while the latter is known for its strong protection and high durability. In addition, there is a clear size difference between 2S/2G and 3S/3G:
-
IF-2S, IF-2G: module size 240 × 120 mm
-
IF-3S, IF-3G: module size 320 × 160 mm
Below, we provide a detailed analysis from four perspectives: technical structure, durability & lifespan, application scenarios, and selection recommendations.
1. Key Technical Differences
Standard Modules (IF-S Series)
These modules use traditional SMD encapsulation, with LED chips soldered directly onto a flexible PCB. The back is fitted with a soft shell and magnetic mounting, making installation straightforward.
Advantages include high brightness, excellent luminous efficiency, and accurate color reproduction. Maintenance is flexible — damaged LEDs can be replaced individually — reducing operational costs.
However, the exposed LED surface means they are more vulnerable to dust, moisture, and physical impact, making them better suited for controlled environments.
GOB Modules (IF-G Series)
GOB (Glue-on-Board) technology seals each LED under a transparent, hardened resin layer. This creates a fully enclosed surface that is dustproof, moisture-proof, impact-resistant, and scratch-resistant while maintaining high transparency for light output.
Repairs typically require replacing the entire module rather than a single LED, but this allows for faster on-site recovery in high-traffic installations where downtime must be minimized.
2. Durability and Lifespan
Performance Index |
IF-S Series (Standard) |
IF-G Series (GOB) |
Dust & Moisture Resistance |
Moderate — requires regular cleaning in clean indoor spaces |
High — fully sealed surface, suitable for humid or dusty environments |
Impact & Scratch Resistance |
Moderate — avoid direct contact or collisions |
High — withstands light bumps and scratches |
Maintenance Method |
Flexible — single LED replacement possible |
Quick — replace the entire module for faster servicing |
Service Life |
50,000+ hours |
50,000+ hours (more stable in harsh conditions) |
In controlled indoor environments, both types can exceed 50,000 hours of operation. In more challenging conditions, GOB modules retain image quality and structural stability for longer.
3. Application Scenarios
Standard Modules (IF-2S / IF-3S)
Best for stable indoor environments with controlled temperature and humidity, where there is little to no physical contact with the screen:
-
Conference rooms and corporate meeting spaces
-
Exhibition halls and art galleries
-
Command and control centers
-
Stage backdrops and large event screens
Advantages: High brightness, vivid colors, flexible maintenance, and cost efficiency.
GOB Modules (IF-2G / IF-3G)
Ideal for high-traffic or challenging environments where the screen may be touched or exposed to dust and humidity:
-
Shopping mall interactive displays
-
Museum interactive exhibits
-
Public transport hubs (airports, subways) wayfinding screens
-
Retail store window advertising
Advantages: Superior protection, safe to touch, and long-lasting image clarity.
4. Selection Advice
When deciding between standard and GOB modules, consider the installation environment, usage pattern, maintenance access, and budget:
Choose IF-2S / IF-3S Standard Modules if:
-
The installation site is climate-controlled with clean air.
-
The display is positioned high or physically isolated from the audience.
-
Maximum brightness and color accuracy are critical for applications like stages, exhibitions, or data visualization walls.
-
You need high image quality on a tighter budget.
-
Flexible, low-cost maintenance is important, with the ability to replace single LEDs.
-
The project is temporary or short-term, requiring quick installation and setup.
Choose IF-2G / IF-3G GOB Modules if:
-
The display is in public or interactive spaces where people may touch it.
-
The environment has higher humidity or airborne dust (near entrances, underground areas, industrial sites).
-
The installation location is hard to access for frequent maintenance.
-
The display is part of a long-term operation, such as a flagship store window or public information screen.
-
The project involves close-viewing, interactive experiences (museum exhibits, retail experience zones, immersive showrooms).
-
The content displayed is high-value, such as art, luxury branding, or premium product visuals, requiring flawless presentation.
Conclusion
Both Standard and GOB modules have their own strengths — neither is “better” in every situation. The key is finding the one that best fits your environment and project needs.
In climate-controlled, clean indoor spaces, Standard modules can deliver bright, vivid visuals at a more cost-effective price, with the added benefit of flexible maintenance.
In high-traffic areas, or locations where the screen may be touched, or where humidity and dust are higher, GOB modules offer stronger protection and long-lasting stability, keeping your display clear and beautiful for years to come.
We hope this comparison and advice helps you choose the option that suits you best, so your LED display project is both visually stunning and reliably durable.
