It is designed for indoor stages, exhibitions, conferences, churches and rental video walls where the nearest regular viewing distance is more than 4m.
This P3.91 indoor LED screen uses a 500×500mm rental cabinet for indoor stages, exhibitions, conferences, churches, corporate events and temporary video walls. Its verified configuration includes SMD2121 LEDs, 65,536 pixels/m², 800–1200 cd/m² brightness and a 7680Hz refresh rate.
The square cabinet format gives rental companies and event contractors more flexibility when building screens with different widths, heights and aspect ratios. P3.91 is generally suitable when the nearest regular viewing position is more than 4m away. Projects with closer viewers, small text or detailed presentation content should also compare a smaller pixel pitch such as P2.976.

Why Choose a 500×500mm Rental Cabinet?
A 500×500mm cabinet gives event crews half-meter control over both screen width and height. This makes it useful for conference screens, exhibition booths, church stages, side displays and video walls that do not match full one-meter height increments.
The square format also helps rental companies reuse the same inventory across different screen sizes. A 3m-wide screen can use six cabinet columns, while a 4m-wide screen can use eight columns. The final number of rows depends on the required height.
Compared with a 500×1000mm cabinet, the 500×500mm version offers greater layout flexibility but requires more cabinets, locks, power connections and signal connections for a large wall. Buyers who frequently build large standard rectangular screens can compare the
P3.91 indoor 500×1000mm rental screen.
500×500mm Is Better When
- Screen heights change between projects
- Side screens or narrow walls are common
- Flexible aspect ratios are required
- Lower individual cabinet weight helps handling
Confirm 500×1000mm When
- Large standard walls are built frequently
- Reducing cabinet and connection count matters
- Fast assembly is more important than half-meter height control
- The crew and transport plan suit taller cabinets
P3.91 Viewing Distance for Indoor Events
The verified planning reference for P3.91 is a viewing distance of more than 4m. At this distance, P3.91 can provide a practical balance between image detail, cabinet quantity and project cost for typical event video, sponsor graphics, stage backgrounds and presentation content.
Viewing distance is not an absolute guarantee of image quality. Small text, detailed spreadsheets, close camera shots and high-end presentation requirements may require a smaller pixel pitch. The final decision should also consider the complete screen size, content resolution, source scaling, ambient light and nearest regular viewer.
If viewers regularly stand closer than 4m, compare the
P2.976 indoor rental LED display.
Buyers who need a wider comparison of pitch, indoor and outdoor configurations and cabinet sizes can also review the
P3.91 LED display guide.
7680Hz Refresh Rate for Camera-Facing Events
The verified P3.91 indoor configuration uses a 7680Hz refresh rate. This is useful for conferences, churches, product launches, live broadcasts, corporate events and stage productions where cameras or mobile devices may record the screen.
Refresh rate alone does not guarantee perfect camera footage. Receiving cards, processor settings, grayscale performance, brightness, camera shutter speed, frame rate and exposure all affect the final result. Buyers should request a complete system test using conditions close to the intended production environment.
Camera acceptance checks
- Test the screen at normal operating brightness
- Record moving graphics and live video
- Check scan lines at the intended shutter speed
- Inspect low-brightness grayscale and dark scenes
- Confirm color consistency across multiple cabinets
Indoor Brightness and IP31 Protection
The 800–1200 cd/m² brightness range is intended for protected indoor environments. Excessive brightness is not automatically better indoors because it can make close viewing uncomfortable and complicate camera exposure.
The verified protection reference is IP31. This panel should not be treated as an outdoor weather-resistant cabinet. Projects exposed to rain, dust, moisture or direct outdoor conditions should use a suitable outdoor version and confirm the complete cabinet protection, including modules, rear doors, connectors and cable interfaces.
Screen Size, Cabinet Quantity and Resolution
Each 500×500mm cabinet has a resolution of 128×128 pixels. Cabinet quantity is determined by dividing the required screen width and height by 0.5m.
Final dimensions must be divisible by the cabinet size. Buyers should also plan spare modules, receiving cards, power supplies, signal cables, power cables and installation accessories. Use the
LED wall calculator
to estimate cabinet quantity and screen resolution before requesting a quotation.
Applications for P3.91 Indoor LED Screens
Conference Halls
Presentation video walls, product launches, meetings and corporate ceremonies where viewers remain at a medium distance.
Church Stages
Lyrics, sermon graphics, live video and stage backgrounds when the closest regular viewing position suits P3.91.
Exhibitions
Booth video walls, demonstrations and branded content where flexible cabinet dimensions support changing stand layouts.
Indoor Stages
Concerts, performances and event backgrounds that require modular installation and camera-facing playback.
Power, Control and Installation Planning
A complete LED wall requires cabinets, receiving cards, a sending or video-processing system, power distribution, signal cables and installation hardware. The processor must support the final screen resolution and required input sources.
Before confirming hanging or stacking installation, the project team should provide the screen dimensions, venue conditions and structural plan. Installation hardware and supporting structures must be selected and approved for the real project rather than assumed from the cabinet size alone.
For rental inventory, clear cable labeling and compatible spare parts can reduce setup time and simplify maintenance. Confirm the required spare-module ratio, receiving cards, power supplies, cables, tools and flight-case layout before production.
Information Required for a P3.91 Quotation
Provide the following information so the screen can be configured for the actual project:
- Required screen width and height
- Nearest regular viewing distance
- Indoor environment and ambient-light conditions
- Hanging or stacking installation
- Camera, livestreaming and content requirements
- Required input sources and video processor
- Destination country and local voltage
- Quantity, project schedule and expected use frequency
- Flight cases, spare parts, cables and accessories
- Trial order, mixed order, OEM or ODM requirements

Frequently Asked Questions
What is a P3.91 indoor LED screen?
It is an indoor LED display with pixels spaced approximately 3.91mm apart. This 500×500mm rental panel uses SMD2121 LEDs, 65,536 pixels/m², 800–1200 cd/m² brightness and a verified 7680Hz refresh-rate configuration.
What viewing distance is recommended for P3.91?
The verified planning reference is more than 4m. Projects with closer viewers, small text or detailed presentation content should also compare P2.976 or another smaller pixel pitch.
Why choose a 500×500mm rental cabinet?
The square cabinet supports flexible half-meter adjustments in both screen width and height. It is useful for changing rental layouts, side screens, exhibition walls and projects that do not match one-meter height increments.
Is this P3.91 panel suitable for outdoor use?
No. This version uses an indoor IP31 protection reference and should not be treated as an outdoor IP65 cabinet. Use a verified outdoor configuration for weather-exposed projects.
Does 7680Hz guarantee flicker-free camera footage?
No single refresh-rate value guarantees every camera result. The complete receiving-card, processor, brightness, grayscale, shutter-speed and frame-rate configuration must be tested together.
How many 500×500mm cabinets are required?
Divide the screen width and height by 0.5m to calculate cabinet columns and rows, then multiply the two values. Spare cabinets and modules should be planned separately according to the project and rental-maintenance requirements.
