What Are LED Display Modules?
LED display modules are the fundamental building blocks of LED video walls and screens, consisting of high-brightness LED pixels mounted on a PCB (printed circuit board). They are designed to form larger indoor LED walls, outdoor LED displays, transparent screens, rental LED screens and custom LED video walls. The performance of the LED module (brightness, pixel pitch, viewing distance, durability) directly impacts the overall quality of the LED screen.
LED Module Key Features & Technology
Pixel Pitch
Determines resolution and optimal viewing distance (e.g., P1.86, P2.5, P3.91).
Brightness
High nit output for outdoor visibility even in sunlight.
SMD / COB Technology
SMD modules provide wide viewing angles, while COB LED modules offer seamless visuals and superior thermal management.
Durability & Weather Resistance
Outdoor LED modules are rated for IP65+ protection to withstand rain, dust, and UV exposure.
Types of LED Display Modules & Typical Applications
Indoor LED Modules
Designed for close-view viewing in conference rooms, retail stores, showrooms and indoor advertising walls.
| Pixel Pitch | Model Example | Viewing Distance | Typical Use Case | Remarks |
|---|---|---|---|---|
| P1.25–P1.86 | Fine Pitch Modules | 1.5–2m | Control rooms, high-end conference rooms | Ultra HD, close-up viewing |
| P2.0 / P2.5 | Standard Indoor Module | 2–3m | Shopping malls, retail displays, hotels | Good balance of clarity and price |
| P3.0 / P3.91 | Cost-effective Indoor Module | 3–4m | Stage backdrops, churches, rental | Widely used for both fixed and rental |
| P4 / P5 | Indoor Large Screens | 4–6m | Lobbies, train stations, exhibitions | For long-distance viewing, large size |
Tip:
If your viewing distance is 2 meters or less, go for P1.25–P2.0.
If you want a cost-effective indoor screen, P2.5–P3.91 is ideal.

P1.86 LED module320*160mm
P2.5 LED module320*160mm
P3.91 LED module 250*250 mm
P5 LED module 250*250 mm
Outdoor LED Modules
Built for high brightness and weather resistance for billboards, building facades and stadium screens.
| Pixel Pitch | Model Example | Viewing Distance | Typical Use Case | Remarks |
|---|---|---|---|---|
| P3.91 / P4.81 | Rental Outdoor LED | 3–5m | Outdoor stage, mobile events | High refresh, waterproof, rental design |
| P5 / P6.67 | Fixed Installation | 5–7m | Storefronts, plazas, advertising boards | Stable & cost-effective |
| P8 / P10 | Large Format Outdoor LED | 8–12m | Building facades, stadiums, highways | Brightest, low resolution but far-viewing |
Key Differences
High brightness (≥5000 nits) needed for sunlight readability
Waterproof and dustproof (IP65 and above)
Rental modules usually lighter, with quick-lock systems

Flexible LED Modules
Flexible LED modules are soft, bendable screens that can be molded to curved or irregular surfaces—ideal for unique designs and creative projects.
| Pixel Pitch | Model Example | Viewing Distance | Typical Use Case | Remarks |
|---|---|---|---|---|
| P2.5 / P3 / P4 | Curved Installations | 2–5m | Museums, design showcases, pillars | High flexibility, magnetic design |
| P6 / P8 | Large Flexible Screens | 6–10m | Stage decor, malls, creative facades | Lower resolution, more visible curvature |
Key Differences
Uses soft PCB & rubber mask for flexibility
Easy to mount on curved structures using magnetic assembly
Ideal for custom shape designs (cylinders, waves, etc.)

Benefits of High-Quality LED Display Modules
High Brightness & Visibility
Clear visuals even in bright environments.
Long Lifespan & Energy Efficiency
LED modules can operate for 80,000+ hours.
Easy Maintenance & Replacement
Modules can be serviced individually.
Scalable & Flexible Installation
Modules combine seamlessly into large display sizes.
How to Choose the Right LED Display Modules
Determine pixel pitch based on the viewing distance and resolution requirements.
Choose outdoor modules with higher brightness (6000+ nits) and IP rating for open-air installations.
Consider module maintenance access (front vs rear service).
