GOB LED Display Module
When you’re planning an LED screen installation, whether it’s for retail signage, control-room walls, event rentals or architectural displays, the module you choose matters. Enter the FGOB LED Display Module (also called GOB LED module), a technology built for durability, precision, and premium visual performance. In this article we’ll walk you through: what GOB (Glue On Board) technology is, the benefits and trade-offs, how it compares to other packaging types (DIP, SMD, COB), how to evaluate quality, typical applications, maintenance tips, and key buying considerations. By the end you’ll be ready to decide whether a GOB LED module is the right solution for your project and how to get the best value.
What is a GOB LED Module?
The term GOB stands for “Glue On Board” and refers to a post-SMT protection process applied to LED modules. According to the manufacturer UNIT LED, after the SMT process finishes, a transparent, high-thermal-conductivity adhesive layer is applied over the lamp beads and module surface. This gives the LED module enhanced protection from water, dust, impact and environmental stress.
Put simply: a GOB LED module is like a standard SMD LED module, but with an extra robust protective coating, improving durability and visual performance in challenging settings.
Key characteristics:
-
Transparent glue filling on the surface of the module to seal lamp beads and components.
-
High-gloss or matte finish depending on design (the glue can be processed to reduce glare).
-
Very good flatness and uniformity, making it ideal for small-pixel-pitch (fine-pitch) displays.
-
Enhanced waterproof, dust-proof and shock-proof features (depending on module design).
Therefore, when you see the term “FGOB LED Display Module”, you’re talking about the same class of technology: fine-pixel-pitch GOB LED modules designed for premium installations.
Why Choose a GOB LED Module?
When you compare display module technologies, GOB offers distinct advantages — especially if your application demands durability, high resolution and long lifespan. Here are the biggest selling points:
Robust Protection & Durability
-
The glue layer creates a shield that safeguards lamp beads against water vapour, dust ingress and mechanical shock.
-
Especially suited to outdoor or semi-outdoor installations, or busy indoor environments (like retail) where screens may be exposed to harsh conditions.
-
Improved impact and scratch resistance thanks to the hard, smooth surface created through the GOB process.
Superior Visual & Viewing Performance
-
The treated surface turns individual lamp beads into a more uniform light-emitting surface. That means better flatness, less “grainy” appearance, better visuals in small-pitch modules.
-
Wider viewing angles: GOB treated modules can achieve horizontal & vertical angles up to ~180°.
-
Reduced glare and better comfort for long-period viewing (important for control rooms, command centres).
Fine-Pixel-Pitch Compatible
-
Because the surface is more uniform, GOB modules suit fine-pixel-pitch installations (for example P1.25, P1.5mm) where visual smoothness is critical.
-
This opens up applications like high-end indoor LED walls, immersive environments, curved or creative screens.
Wide Application Scope
-
The technology supports indoor and outdoor use, soft/flexible modules (for curved displays), floor screens, retail shelf displays, poster modules, etc.
-
Because of its durability, it is especially well-suited to challenging or high-traffic areas (shopping malls, transportation hubs, event venues).
What Are the Trade-Offs?
No technology is perfect, and it’s important to understand the limitations of GOB LED modules so you make an informed decision.
More Complex Maintenance
-
If a lamp-bead fails within a GOB module, the protective layer means repairs require specialised tools (heat gun to remove glue, careful resealing) and higher maintenance cost.
-
Not as easy to “pop out” module parts compared to simpler SMD modules.
Process and Cost Considerations
-
The glue-filling and sealing process is more technically demanding: uniform glue thickness, avoidance of air bubbles/white spots, long aging time etc.
-
Because of the additional process, cost may be higher than standard SMD modules (though the durability and performance often justify the premium).
Repair/Service Complexity
-
In very severe outdoor or rental settings (especially transparent or floor modules), the protection may still fall short of the finest specialist display technologies.
-
For extremely harsh usage conditions, you still need to select modules rated for those conditions (e.g., full outdoor IP65+ etc).
How GOB Compares to Other LED Module Technologies
To better appreciate the benefits of GOB modules, let’s compare it to the main alternatives: DIP, SMD and COB.
DIP (Dual Inline Pin) Modules
-
DIP uses large lamp beads mounted through wave-soldering, an older tech.
-
High brightness, decent outdoor performance.
-
GOB beats DIP for fine-pitch indoor or mixed use scenarios.
SMD (Surface Mount Device) Modules
-
SMD is the dominant package; RGB lamps mounted on board; wide use indoors & outdoors.
-
Cost-effective, broad compatibility
-
GOB enhances the SMD base by adding the protective coating, giving SMD-level flexibility plus ruggedization.
COB (Chip On Board) Modules
-
COB mounts bare chips directly on board followed by glue encapsulation; advantages are ultra thin, impact resistant, smooth surface.
-
Cons: higher cost, newer tech, still maturing.
-
GOB is a different packaging concept: it is a protection process applied after module production, not a full chip-level packaging.
-
For many fine-pitch use-cases, GOB offers near-COB performance with less cost or risk.
Key Specifications & What to Look For
When you evaluate an FGOB LED display module, here are the critical specs and quality markers to check:
Pixel Pitch
Defines the centre‐to‐centre distance between LED pixels. Fine pitches (P1.25mm, P1.5mm, P1.8mm, P2mm) give higher resolution for closer viewing.
Make sure the module’s pixel pitch suits your viewing distance and resolution requirement.
Brightness (Nits)
Brightness needs depend on your installation (indoor vs outdoor). For example the specification list from Unit LED shows 600-1000 units for various modules.
Ensure the module meets ambient light requirements.
Driving Mode & Scan Mode
Check the scan mode (1/64, 1/52 etc) and driving technology, this will affect refresh rate, uniformity, power consumption.
A higher refresh rate and stable driving mode reduce flicker and improve image quality.
Protection Rating & Surface Treatment
Since GOB modules are about protection, verify the following:
-
Is the glue layer uniform and bubble-free? (Check manufacturer process)
-
What is the dust/water/impact proof level (IP rating if provided)?
-
How is the surface finish (matte vs glossy) and does it suit your installation (glare reduction for indoor use)?
-
Does the module give wide viewing angles (approaching 180°)?
Heat Dissipation and Lifespan
Good modules will use PCBs of sufficient thickness (e.g., >1.6mm), high-quality solder paste and LED beads from reputable brands.
Proper aging and thermal testing ensure long lifespan and colour consistency.
Flexibility or Customisation
If you need curved displays, floor screens or irregular shapes, check if the GOB module supports soft/flexible versions.
Also check spare-parts availability, warranty, after-sales support.
Applications & Use-Cases
The FGOB LED display module is versatile. Here are common applications where it excels:
Small-Pitch Indoor Video Walls
For control rooms, broadcast studios, corporate lobbies, conference halls, high resolution + uniform appearance + durability. GOB modules suit such settings well due to minimal visible lamp beads and wide viewing angles.
Outdoor or Semi-Outdoor Signage & Retail Display
High dust and weather resistance mean GOB modules can be used for facades, outdoor retail screens, shopping-mall atriums. The glue layer protects the lamp beads.
Creative & Curved Displays
Flexible GOB modules enable cylinder screens, spherical displays, wave forms, and other non-flat installations. This opens up creative environments for events, exhibitions, and architectural features.
Floor LED Displays and High-Traffic Zones
In environments where the display may be walked on or exposed to impact, the GOB module’s strong surface and protection help. (E.g., retail floors, interactive installations)
Rental & Event Displays
In rental use where modules are frequently moved, impacted, re-installed and subject to rough handling, the higher durability of GOB modules is advantageous.
How to Choose the Right GOB LED Module?
Here’s a practical checklist for your selection process:
-
Define viewing distance & resolution needs: For close-up indoor use, choose small pixel pitch (P1.25mm, P1.5mm). For further distances, P2mm or higher may suffice.
-
Estimate ambient conditions: Bright sunlight? High dust/sand? Outdoor exposure? Choose modules with appropriate brightness (nits) and environmental protection (dust, water).
-
Check manufacturer credentials: Ensure the supplier, like Unit LED, provides clear specs, process information (ageing, glue process, raw materials). For instance, Unit LED claims high transparency glue, strong adhesion, high-temp resistance etc.
-
Surface finish & visual quality: If the screen will be viewed closely, ensure the module surface is smooth and uniform (GOB process aims for this).
-
Serviceability & spare parts: Even high-quality modules will need maintenance. Check longevity, spare module availability, technical support.
-
Budget vs value: GOB modules may cost more than standard SMD. But factor in savings from fewer failures, less maintenance, better visual performance, longer lifespan.
-
Installation environment & flexibility needs: Need curved display? Floor tile screen? The Confirm module supports bending/flex and floor load if applicable.
-
Warranty & after-sales: Look for documented warranty, free spare parts, technical support promised by manufacturer (Unit LED states “15 Years LED Display Manufacturer, 3 Years Quality Guarantee, 5% Module Spare Parts, Free Technical Support, 24 Hours After-Sales Service.”)
