250×250 mm Epround panel · indoor 48S with 2020 lamps & outdoor 48S with 1921 lamps · 4,096 pixels per panel · 65,536 px/m² · dual-weather touring
The P3.91 rental LED display is the workhorse band of Excel LED’s 250 mm touring platform — 250×250 mm panels, 64×64 = 4,096 pixels per board, a shared 48S drive with indoor 2020 lamps and outdoor 1921 lamps — for festivals, stadium side walls and open-air shows that want proven tour reliability at the lowest per-pixel cost. Supplied by Excelled, a trusted LED display manufacturer for global B2B rental houses and integrators.

Quick Answer: What Is a P3.91 Rental LED Display?
A P3.91 rental LED display is a 3.91 mm pixel pitch video wall built from 250×250 mm touring panels with quick-lock frames and flight-case travel.
• Module data (confirmed): 250×250 mm panel · 64×64 = 4,096 pixels · indoor build 48S with 48 driver ICs and 2020 lamps · outdoor build 48S with 48 driver ICs and 1921 lamps.
• Resolution: 65,536 pixels per m² — the most economical band of the 250 platform, sized for walls viewed from about 4 m and further.
• Dual use: one panel family covers indoor stages and weather-exposed outdoor stages, each with its own lamp family on the same 48S drive.
• Rental engineering: die-cast quick-lock panels, front service, flight cases, and control matched by one factory.
One-Stop Solution
One-Stop Solution for P3.91 Rental LED Display Walls
Excel LED (LEGIDATECH) supplies the P3.91 rental LED display family end-to-end: the 250×250 mm Epround platform in two factory configurations — indoor 48S with 48 driver ICs on 2020 lamps for halls and studios, and outdoor 48S with 48 driver ICs on 1921 lamps for weather-exposed shows — plus quick-lock aluminum frames, flight cases, receiving cards and the rigging plan.
Both builds share the same 250×250 footprint, locking hardware and 48S drive, so a rental fleet runs indoor and outdoor walls from one panel stock: the outdoor boards swap into the same frames and cases as the indoor boards, and the control topology stays identical. One BOM covers the whole fleet — the same hardware philosophy that runs across the fine end of the platform on the P1.953 rental LED display page, the mid rows on the P2.604 rental LED display page and the value band on the P2.976 rental LED display page.
Rental buyers usually reach 3.91 mm from two directions: down from fine-pitch panels to open up the budget for more square meters, or up from coarse outdoor rental for tighter stage graphics. If you are still mapping the family, the indoor fine-pitch LED display hub explains the pitch ladder above 3.9 mm, and this page covers the 3.91 mm workhorse row of the same touring platform.

Series & Formats
P3.91 LED Display Formats: Rental Panels vs Fixed Walls
P3.91-class pixels exist in rental and fixed formats, and the price follows the format, not the pitch. The rental P3.91 panel (this page) is a 250×250 mm self-contained touring unit with indoor and outdoor builds; a fixed indoor wall builds from larger cabinets and never comes down. Both read similarly from typical event distances — the difference is teardown, transport and rebuild speed.
| Format | P3.91 rental panel ★ | Fixed indoor wall |
|---|---|---|
| Panel / module | 250×250 mm touring panel (confirmed) | 320×160 / 480×320 platform |
| Builds | Indoor 48S · outdoor 48S (confirmed) | Indoor only |
| Structure | Die-cast aluminum quick-lock (typical) | Permanent aluminum cabinet |
| Weather | 1921-lamp outdoor build for stage exposure | Not weather-rated |
| Transport | Flight cases, stackable (typical) | Forklift / pallet only |
| Use | Festival, tour, event | Lobbies, studios, retail |
Inside the rental family, the Epround-style 250 platform spans several pitches with identical hardware — same cases, same locks, same flying frames. P3.91 is the most economical row of that platform: coarser than the value band at P2.976, and the stepping point where a touring fleet buys the most square meters per dollar while staying inside the 250 ecosystem.

Outdoor Build
The P3.91 Outdoor Rental LED Screen: 48S, 1921 Lamps, Stage Weather
Outdoor touring is where 3.91 mm earns its keep at festival scale. The outdoor P3.91 rental LED screen runs 48S scan with 48 driver ICs on 1921 lamp beads — the weather-grade lamp family used across the factory’s outdoor rack — so open-air main stages hold their image under daylight, stage wash and afternoon haze.
Weather exposure on a tour is handled at the system level: sealed module faces and treated frames keep moisture off the drive electronics, while tails and locks stay protected in cases between shows. Outdoor panels on this platform are rigged under stage roofs or on weather-tolerant truss positions; the factory confirms the sealing class on each outdoor BOM.

Rental Engineering
Rental Cabinet Engineering: Quick Locks, Cases and Flying Frames
P3.91 rental panels are built for the road, not for a wall. The die-cast aluminum frame carries quick-lock connectors so two panels join with a single push — no tools, no loose parts, no clips to lose in a travel case. Panels lock in two directions at once, so a wall stacks vertically without shims, and blocks of 4 panels (500×500 mm) are the standard rebuild unit.

Case and spare ratios that keep tours alive
Flight cases come sized to the fleet: the standard case carries a block of panels face-forward with foam cradles, so panels load straight into the wall and straight back in. A rental house typically stocks a 5–10% spare-panel ratio — LED modules and receiver cards are the consumables that tour hardest, and the factory can pre-pack matched spares for the BOM.
Weight and rigging planning
Die-cast panels are light per square meter, but the rigger’s load is per hanging meter, so weight per square meter must be confirmed against the truss spec before the wall is built. Flying frames bolt across panel columns and take the load through the frame, never through the lock points. The factory supplies the rigging plan with each tour BOM at the requested aspect ratio.
Quality
P3.91 LED Screen Quality: Scan, ICs and the Lamp Difference
At 3.91 mm the panel is the same weather-tested structure as the fine rows of the platform, with quieter electronics: fewer pixels per panel means the 48 driver ICs work harder per lamp but with more headroom, and the on-board IC runs the whole frame with no extra cabinets, processors or cooling loops.
Why the indoor P3.91 uses 2020 lamps at a coarser pitch
Finer panels move to 1515 beads because cells get physically small at 2 mm pitch; at 3.91 mm there is nothing to win by shrinking the lamp. The 2020 SMD bead keeps a large, bright surface area, which is why indoor P3.91 panels show a slightly different texture at close range than fine-pitch walls — and why they are far more forgiving on brightness headroom when the wall gets pushed.
Why outdoor uses a different lamp at the same pitch
Outdoor exposure changes the requirement: the same pixel budget must deliver several times the brightness plus sealed protection against rain, UV and thermal cycling. The 1921 SMD bead sits on the factory’s outdoor rack for that reason — the same panel geometry, a lamp built for both output and endurance.
Scan 48S: one drive, both builds
With only 64×64 pixels per panel, a 48S scan is enough to refresh each row twice per frame while keeping current per LED low — which is what an outdoor build needs for sustained brightness. Indoor and outdoor builds share the same 48S drive and the same 48 driver ICs, so one spare card covers both weather classes on a mixed fleet.
Repair philosophy for touring panels
On tours, downtime is the expensive failure, so panels are built front-serviceable: the module face releases from the front of the frame, and a defective module or receiver card swaps without taking the wall down out of the truss. Spares ship in the flight case, and the factory ages each batch 72 hours before packing.

Applications
Where the P3.91 Rental LED Display Earns Its Place
P3.91 is the broad-workhorse row of the 250 platform: sharp from the back rows, forgiving of budget, and proven in every weather class that shows get booked in.
Festival and stadium stages (outdoor build)
Outdoor main stages read from 20 m or 30 m away, and no audience at that distance can resolve the difference between 3.91 mm and 2.6 mm. The outdoor 48S build on 1921 lamps delivers the brightest image per dollar, which is exactly where festival rental fleets concentrate their floor spend.
Indoor tours and award shows
For indoor sits with camera and lighting at a distance, P3.91 stops looking coarse around 4–5 m, which covers most arena galleries and second-tier production seats. It is also the standard choice for single-day corporate shows where the wall goes up in hours — lighter BOM, faster rebuild.
Hybrid fleets: one panel family, two weather classes
Because indoor and outdoor builds share the same frame, locks, cases and 48S drive, a mixed fleet stocks only one panel platform and buys the lamp build per show. That is the real cost argument for choosing 3.91 mm on the 250 platform instead of a cheaper off-platform solution: every accessory is already interoperable.
Conference and exhibition backdrops
Exhibition halls are indoors, but they are also short-fidelity environments: people walk, stop, and read the content from across a booth. 3.91 mm is a common choice for backdrops that carry big type and high-output imagery rather than dense live data — exactly the pattern of a tradeshow stage.
Buying Guide
How to Choose a P3.91 Rental LED Display: Indoor or Outdoor, Panels, Cases
Start from the show you will actually run, then work backwards to the BOM. Three decisions — lamp build, panel quantity, and case/spare ratio — cover most of the ordering work on P3.91.
- Decide the weather class first. An outdoor build is a mandatory choice for anything without a roof; an indoor build will save money on a wall that never sees sun. Both are 48S on this platform, so the rest of the spec does not change.
- Work out the wall from blocks, not meters. The rebuild unit is a 500×500 mm block of 4 panels. Compute the wall in blocks — a 6×3 m wall is 12×6 blocks of 250 mm, so 72 panels — and add one spare block for the tour.
- Match the processor to the wall and the camera. The receiving cards are specified per panel, but the wall processor and refresh must be chosen for the camera gear that will roll on the show, not just for output.
- Check the viewing distance law. At 3.91 mm, the panel can’t be read at laptop range; its best viewing distance is around 4 m and further, and at 8 m it is as crisp as any projection.
What drives P3.91 rental LED display price
Three cost lines decide the quote on a P3.91 rental LED display — the panel BOM, the travel gear, and the floor-to-wall plan. On panels, the 1921 outdoor build costs a little more per sqm than the 2020 indoor build because the lamp is heavy-duty, while both share the same platform, boxes and controllers. On the travel gear, flight cases, spare panels and spare receiver cards are usually close to a fifth of the panel budget — and all of it is factory-priced in one BOM. On the plan, ground-supported and flown walls price differently because of the frame and rigging: a 4×6 m wall in a convention center needs different flight cases per column than a 8×3 m wall on a stadium tour. Everything else stays fixed: each kit ships with the wall processor, the receiving cards, and the full case stack, from the same factory.

Math
P3.91 LED Display: Resolution and Viewing Distance Math
The visual behavior of a P3.91 rental LED display follows the same two rules as every other pitch: pixel density decides how many paragraphs of text you can fit on the wall, and viewing distance decides how close your audience can get before they see dots.
Density. At 3.91 mm, each 250×250 mm panel carries 64×64 = 4,096 pixels, or 65,536 pixels per m². A 12×6 m festival back wall is 72 m² ≈ 4.7 million pixels — that’s roughly 24× 1,160×600-spot resolution, comfortable for brand graphics and imagery; fine-detail data walls at the same size would leave pixels unused.
Viewing distance. Approximate the most demanding view distance in millimeters by multiplying the pitch in millimeters by 1000 — that’s ~3.9 m for 3.91 mm. Under that, viewers will see the pixel structure; from that distance out, the image reads clean, and at ~8 m it looks as sharp as a projector wall.
Scale rule-of-thumb. If a wall is twice as far away, budget twice the pitch, keeping the same virtual footprint. A 4 m viewing distance says 3.91 mm works; at 8 m, P7.8-class pixels are equivalent; at 2.5 m only fine-pitch works. This is why the same 250 rental platform adds finer rows on the P1.953 / P2.604 / P2.976 pages — the same touring hardware, a different pitch per audience distance.
Why Us
P3.91 Rental LED Display — Workhorse Panels That Tour Indoors and Out
Why choose an Excel LED P3.91 rental LED display
- Confirmed factory data. Every lamp, scan and driver IC row on this page comes from the factory module price list — 64×64 = 4,096 px, 48S, 2020 indoor / 1921 outdoor — not from marketing copy.
- One end-to-end BOM. Panels, frames, cases, spare modules, receiving cards, wall processor and rigging plan quoted by one factory, so nothing falls between two vendors.
- Two weather builds, one fleet. Indoor and outdoor panels share the platform and the 48S drive; a mixed rental fleet swaps boards per show without changing cases or control.
- Touring-tested QC. Every batch is aged 72 hours and brightness-calibrated before packing.
Maintenance method for P3.91 rental LED displays
Daily maintenance is a wipe and an inspection. After each show: sweep dust off the face with a dry soft cloth, check the quick-lock latches for debris, and look for cracked faces around road hits. Monthly, do a full-face check for dead pixels — a module with a failed LED swaps frontward in minutes with no truss teardown. The fixed QC cost is paid once per package; the rest is miles vs. spare modules.
Packaging of P3.91 rental LED displays
Tour packaging is flight cases, not cartons. Panels sit face-forward in foam cradles per case, edge-down, so locks and tails stay untouched — a standard 6-case stack carries one 3×3 m wall, or the 500×500 mm blocks of any wall you build from it. The wall processor is hard-mounted and crash-safe in a fitted service case, along with pre-flight instructions for the technician.
Which Module Sizes Does a P3.91 Rental LED Display Use?
This pitch is quoted in 1 module format in our production list. All of them produce the same 65,410 px/m² wall — they differ in board size, how many fit a cabinet, drive scheme and serviceability. Pixel figures below are exact arithmetic from the pitch (1,000 ÷ 3.91 mm = 255.8 px per metre), cross-checked against the factory module list.
| Module size | Resolution & dots | Per cabinet | Boards per m² | LED & drive | Notes & service |
|---|---|---|---|---|---|
| 250×250 mm | 64×64 px 4,096 dots |
4 | 15.97 | 2020 SMD · 48 ICs · 48S scan | front service |
Which Cabinet Sizes Does a P3.91 Rental LED Display Ship In?
500×500 mm is the standard carrier for this pitch: 4 panels (500×500 mm free-standing block), resolving to 128×128 — 16,384 px. Every further format below is built for a specific layout problem rather than for a better picture.
| Cabinet (W×H) | Modules inside | Resolution | Weight / body | Service access |
|---|---|---|---|---|
| 500×500 mm | 4 panels (500×500 mm free-standing block) | 128×128 16,384 px |
Die-cast aluminum quick-lock (typical) | front service (typical) |
Why 500×500 mm became the rental standard grid
Rental geometry is driven by touring, not by the building. Four cabinets make a square metre, so stage arithmetic stays mental. One cabinet size fits every pitch in the 250×250 mm module family, so a rental house stocks one chassis and swaps modules. Flight cases and rigging bars are dimensioned around it, and the same cabinet hangs on a truss or stacks on a stage lip.
Industry-standard cabinet grids for this module size (on request)
These grids are the ones the industry builds around this module size, and each one is arithmetic-clean — the modules tile with no cut strip. They are quoted on request rather than stocked, and the pixel figures are pure arithmetic from the pitch.
| Cabinet (W×H) | Modules inside | Resolution & pixels | Grid status |
|---|---|---|---|
| 500×1000 mm on request |
2 × 4 × 250×250 mm modules (2 × 4) | 128×256 32,768 px |
standard indoor rental grid |
| 1000×1000 mm on request |
4 × 4 × 250×250 mm modules (4 × 4) | 256×256 65,536 px |
standard indoor rental grid |
Which cabinet form should you pick?
- Touring stage and event walls → 500×500 mm cabinets on quick-lock frames; curved-corner and angled options available.
- Tall scenic walls and LED banners → 500×1000 mm cabinets: half the horizontal seams per metre of height.
- Screen that must be built and struck in hours → air or quick-lock frame plus flight cases, not a fixed die-cast grid.
- Mixed inventory with other pitches → keep to the 250×250 mm module family so one chassis serves several pitches.
- Permanent indoor install with no touring → a fixed cabinet is cheaper per square metre than a rental chassis.
Which Control Systems Work With a P3.91 Rental LED Display?
A P3.91 Rental LED Display is electrically ordinary: standard HUB75 module interface, conventional indoor scan, low-voltage module rails. That is why it accepts essentially every mainstream control ecosystem — the real decision is not “which system is compatible” but which family your operators already run, because sending cards and receiving cards must come from the same family.
The signal chain, end to end
- 1. Video source — media player, PC, camera or streaming decoder.
- 2. Video processor / sending card — scales, switches and packetises: HDMI / DVI / SDI in, gigabit Ethernet out.
- 3. Transport — Cat6 for normal runs, fibre where the distance or the lightning risk demands it.
- 4. Receiving card — one receiving card per cabinet is the standard loading (16,384 px per cabinet).
- 5. Modules — 4 panels (500×500 mm free-standing block) per cabinet, daisy-chained POWER IN/OUT and SIGNAL IN/OUT.

How many receiving cards does a P3.91 Rental LED Display need?
Two limits decide the card count, and the smaller one wins. Pixel capacity: one 500×500 cabinet carries 16,384 px, and a mid-range card such as the MRV336 loads 256×256 = 65,536 px at 60 Hz — that is 4 cabinets per card. Port loading: the same card has 12 HUB75 outputs, and a cabinet here needs 4 module feeds, so the ports allow 3 cabinets. The binding limit is 3 cabinets per card (the port count).
- Redundancy — on revenue-critical walls add a second sending card in hot standby; a failed cabinet still does not take the wall down.
- Remote management — NovaStar and Colorlight sending platforms report cabinet temperature and voltage and support scheduled brightness by time of day.
- The one rule that saves the most money — sending card and receiving cards from the same family. Mixing families is the most common commissioning failure we get called about.
- Documentation — the port map, receiving-card loading sheet and configuration file ship with every order.
The architecture of each role — sender, processor, receiving card, async player — is compared in our LED control system collection.
FAQ
Frequently Asked Questions About P3.91 Rental LED Displays
Q1 What is a P3.91 rental LED display?
A P3.91 rental LED display is a 3.91 mm pixel pitch video wall built from 250×250 mm quick-lock touring panels, each carrying 64×64 = 4,096 pixels. It comes in an indoor 48S build on 2020 lamps and an outdoor 48S build on 1921 lamps, with die-cast aluminum frames, flight cases and one-factory control. It is the most economical row of the 250 mm touring platform.
Q2 How many pixels does a P3.91 rental LED panel have?
A 250×250 mm P3.91 panel has 64×64 = 4,096 pixels, which works out to 65,536 pixels per square meter. Panels assemble into 500×500 mm blocks of four, so a wall doubles its resolution budget as you widen it — a 6×3 m wall is roughly 1.18 million pixels, or about 6× a 1080p frame.
Q3 What is the difference between the indoor and outdoor P3.91 LED display builds?
Both builds share the same 250×250 mm panel, 4,096 pixels and 48S scan with 48 driver ICs. The difference is the lamp: 2020 SMD beads for indoor shows and 1921 SMD beads for weather-exposed outdoor shows, the latter delivering higher brightness in a sealed package. Frames, cases, locks and control are identical, so spares interchange across the fleet.
Q4 Can a P3.91 LED display be used outdoors?
Yes — choose the outdoor 48S build on 1921 lamps. It is weather-rated for stage exposure: sealed module faces, treated frames, and a high-brightness lamp that keeps the image readable during daylight shows. Rigging still goes under a stage roof or on a weather-tolerant truss position, and the factory confirms the sealing class on each outdoor BOM.
Q5 What does 48S scan mean on a P3.91 rental LED display?
48S is the scan ratio — the panel refreshes its LED matrix in 48 passes per frame, with rows lit in groups instead of all at once. On P3.91 it means 48 driver ICs per panel, two rows refreshed in turn, and low current per lamp. At just 4,096 pixels per panel, 48S is enough to keep bright outdoor output running without overloading the drive ICs.
Q6 Is P3.91 the same as a P4 LED display?
No. P3.91 (3.91 mm) and P4 (4 mm) look similar at a distance — both are 250-platform or equivalently sized rental rows — but at P4 the panel is 250×250 mm with 64×64 pixels and 160×160 px per module in some fixed platforms, while P3.91 keeps a slightly finer cell. If your audience sits within 4 m of the wall, the P3.91 holds the sharper image; beyond that, P4 saves budget for the same floor.
Q7 How much does a P3.91 rental LED display cost?
For current pricing in USD/GBP/EUR/AUD — plus the full specification sheet, sample policy and delivery time for your country — please request a factory quote here. P3.91 is the most economical row of the 250 platform, and the single biggest cost line on a quotation is the outdoor vs. indoor lamp build, followed by flight cases and spare panels.
Q8 What is the best viewing distance for a P3.91 LED screen?
About 3.9–4 m and further. Multiply the pitch in millimeters by 1000 to get the rough nearest view distance — 3.91 mm × 1000 ≈ 3.9 m. Audience members closer than that see the pixel grid; beyond it the image reads clean, and from about 8 m it looks as continuous as a projection wall.
Q9 What is the difference between P3.91 and P2.976 rental LED displays?
Same 250×250 mm platform and quick-lock hardware; different pitch and drive. P3.91 carries 4,096 pixels per panel at 48S (2020 indoor / 1921 outdoor) and 65,536 px/m²; P2.976 carries 7,056 pixels at 54S indoor / 72S outdoor and 112,896 px/m² — about 72% more pixel data at roughly twice the screen cost. If your audience is 4 m away, P3.91 is the value pick; closer, go P2.976.
Q10 How long does it take to assemble a P3.91 rental LED wall?
A trained two-man crew assembles about 25 m² per hour with the quick-lock system: panels snap together without tools, blocks of 4 panels form a 500×500 mm unit, and the flying frame sets the wall in one pass. A 30 m² wall normally takes under two hours to build and one hour to strike — plus cable and processor setup separate.
Q11 What maintenance does a P3.91 rental LED display need?
Light routine: wipe the face after each show, check the quick-lock latches for debris, inspect for cracked faces after road hits, and stop the aging loop at first sign of dead pixels. Modules and receiver cards are front-serviceable and swap in minutes. Slightly deeper maintenance every 6-12 months: professional dusting, panel-tightening stage, and spare-supply top-up.
