What Is a P3.91 LED Display?
A P3.91 LED display is an LED screen with a 3.91mm pixel pitch. As a general reference, P3.91 is often suitable for viewing from around 4 m.
The 3.91mm pitch provides a practical balance between image detail, screen size, and project cost.
This makes P3.91 a common choice for stages, events, churches, exhibitions, rental screens, commercial spaces, and outdoor advertising.

P3.91 Indoor vs Outdoor LED Display
P3.91 indoor and outdoor displays use the same 3.91mm pixel pitch, but the cabinet design, brightness, and environmental protection are different.
Choose the configuration based on where the screen will operate, not simply because one is more durable.
| Factor | Indoor P3.91 LED Display | Outdoor P3.91 LED Display |
| Brightness | 600-800 nits | 4,500+ nits |
| IP Protection | Basic | IP65 or appropriate rating |
| Cabinet Design | Lightweight | Weather-resistant |
| Typical Projects | Stage, church, exhibition | Billboard, façade, outdoor event |
| Main Concern | Installation & viewing | Sunlight & weather |
If the screen will face direct sunlight, rain, or dust, choose an outdoor P3.91 LED display. Otherwise, choose an indoor P3.91mm display.

Figure 1: Close-up details of P2.97, P3.91, and P4.81 modules; Figure 2: Image quality of the P3.91 LED screen at a distance of 4 meters
For rental LED screens, don’t choose the smallest pixel pitch by default. Start with viewing distance, event type, and the screen size you need, then select the pitch that fits the job.
| Pixel Pitch | Best For | Min Viewing Distance | Rental Buyer Consideration |
| P2.97mm | Close-viewing events, premium stages | 3m | Better image detail, higher investment |
| P3.91mm | General stage & event rental | 4m | Good balance of image detail and cost |
| P4.81mm | Large stages, outdoor events | 5m | More economical for large screens and longer viewing distances |
How We Recommend Choosing
- If your audience will be relatively close to the screen, or the event involves detailed content and close-up camera shots, look at P2.6.
- When you need a balance between image quality and budget for events, choose P3.91mm.
- Choose P4.81 when the screen is large, the audience is farther away, or project cost is a stronger consideration.

2. P3.91 LED Display Cabinet Options

(1) 500 × 500mm / 500 × 1000mm Rental Cabinets

- Which Cabinet Should You Choose?
Rental projects: Choose 500 × 500mm or 500 × 1000mm cabinets when flexibility, transportation, and repeated installation matter.
Outdoor fixed installation: Choose a larger custom cabinet when the screen is permanently installed, and the structure allows larger panels.
3. How to Choose the Right P3.91 Configuration
Step 1 — Indoor or Outdoor?
Indoor projects normally need less brightness and weather protection; outdoor projects require a configuration designed for sunlight, rain, and dust.
Step 2 — How Far Will People Sit from the Screen?
If viewers will stand very close, consider P2.97 or a finer pitch. For medium-distance viewing, P3.91 is often a practical choice.
Step 3 — Rental or Permanent?
This determines the cabinet, locking system, and maintenance design.
Rental screens need lightweight cabinets and fast connections; fixed installations can use larger cabinets optimized for the site structure.
Step 4 — Will the Screen Be Filmed?
For concerts, corporate events, and live productions, a P3.91 LED screen with 3,840Hz helps reduce visible scanning and flicker on camera.
Step 5 — What Screen Size Do You Need?
Give us the required width and height first. We can then work out the cabinet layout and suitable processor configuration.
4. What Affects P3.91 LED Display Price?
The final cost of a P3.91 LED display depends on various factors, including cabinet design, screen size, and customization services.
- Indoor or Outdoor
Outdoor screens cost more because waterproof materials, sealed cabinets, and outdoor-rated components add to the cost compared with a standard indoor configuration.
- Cabinet Design
P3.91 rental cabinets, fixed-installation cabinets, and interactive floor LED display cabinets require different structures, materials, and protection levels.
- LED Package
P3.91 GOB LED screens cost more than SMD P3.91 screens because of higher durability and protection capability.
- Screen Size
A larger screen means more cabinets, modules, power supplies, and processing capacity. Screen width and height are therefore the first figures we need for an accurate quotation.
- Brightness
Outdoor P3.91 LED stage screens exposed to direct sunlight require higher-brightness LEDs and related components to maintain visibility.
- Custom Configuration
Special cabinet designs can significantly change the quotation. Examples include 45-degree beveled cabinets for right-angle installation and curved locks for curved screens.
For an accurate P3.91 LED display price, send us your screen size, installation environment, and application. Vibo LED will recommend the appropriate configuration and quote the project based on the actual requirements.
