Outdoor P4 LED Display
4 mm pixel pitch · weatherproof fixed screen · 62,500 pixels per m² · IP65 front protection
The Excel LED outdoor line at 4 mm — 320×160 mm modules with 1921 black lamps and 60 driver ICs, about 62,500 pixels per square meter, built for billboards and long-zone viewing in full sun — supplied by Excelled, a trusted LED display manufacturer for global B2B system integrators.
Quick Answer: What Is a P4 Outdoor LED Display?
A P4 outdoor LED display is a weatherproof LED video wall with 4 mm between adjacent pixels — 62,500 pixels per square meter — built from high-brightness 320×160 mm modules that keep large-format content sharp in direct sunlight.
• Confirmed module data: 320×160 mm, 80×40 resolution (3,200 pixels), 60 driver ICs, 1921 lamp beads; scan configuration referenced at 10S.
• Weather protection: IP65-rated front face with sealed modules and corrosion-treated cabinets, built for rain, UV and temperature swings.
• Brightness: high-brightness class (typical) — the 4 mm outdoor module is the economical step of Excel LED’s fixed outdoor line for billboard-scale walls.
• Best viewing distance: about 4 m and beyond — the density-to-price sweet spot where a P3.076 wall becomes over-specified and text stays legible far back.
One-Stop Solution
One-Stop Solution of P4 Outdoor LED Displays
Excel LED (LEGIDATECH) builds outdoor P4 LED screens end-to-end: lamp bead sourcing, module assembly with glue sealing, cabinet fabrication, receiving-card wiring, aging and luminance calibration, then global shipping and project support. You order one BOM instead of stitching together modules, power supplies and controllers from different factories.
Inside a P4 outdoor wall, every part is chosen for the outside world: 1921 black lamps with a wide viewing cone for contrast in daylight, IP-rated module sealing, surge-protected power, and a steel or die-cast aluminium structure that carries wind load and drains water. The same cabinet line also serves the outdoor P3.076 and outdoor P2.5 screens, so spare parts and maintenance training carry over across the family.
Within the Excel LED range, the outdoor P4 slot is the value leader of the fixed small-pitch family: the same 320×160 mm module platform as its finer siblings, but with 3,200 pixels per module instead of 5,408 or 8,192 — which is precisely why it costs less per square meter. If your closest viewer stands around 4–8 m away, outdoor P4 is where the billboard budget goes furthest.

Series & Formats
P4 Outdoor LED Display Series: Fixed, Rental and Flexible Carriers
Excel LED carries outdoor small-pitch boards in three carrier formats, and the configuration on this page is the fixed outdoor series — the one used for billboards, roadside signs and building facades that run every day in the same place.
| Format | Fixed outdoor P4 ★ | Rental outdoor platform | Flexible outdoor boards |
|---|---|---|---|
| Module carrier | 320×160 mm (confirmed) | 250×250 mm | 320×160 mm soft boards |
| Frame | Steel or die-cast aluminium | Flight-case racked | No rigid frame |
| Typical use | Permanent billboard & roadside signs | Stage & event touring | Curved facade wraps |
| Service access | Front- or rear-service per site | Rear, bench service | Front, magnet-held modules |
Rental walls on this density class use a 250×250 mm module platform covered under the rental family pages, and curved outdoor installations ride on flexible LED screen boards. For a permanent outdoor P4 video wall, the fixed series below is the standard recommendation — it survives years of sun, rain and thermal cycling with the lowest total cost of ownership per square meter.
Cabinet
P4 Outdoor LED Display Cabinet: Weatherproof Construction
An outdoor P4 wall is assembled from weatherproof cabinet units, and every cabinet is a box of modules, power supplies, receiving cards and cabling sealed against the elements. Because billboard and facade sizes differ, Excel LED quotes the cabinet layout per project — the construction principles below stay the same.
| Parameter | Specification |
|---|---|
| Cabinet type | Fixed outdoor cabinet, steel or die-cast aluminium (typical) |
| Front protection | IP65 — sealed against rain and dust ingress (typical) |
| Rear protection | IP54-class service access with gasketed rear cover (typical) |
| Surface treatment | Corrosion-resistant coating and UV-stable paint; drains and weep holes per module row |
| Service access | Front-service or rear-service layout, chosen per mounting situation |
| Structure | Steel frame sized to wind load; mounting brackets for pole, billboard or facade |
The logic chain is simple: rain comes from the front, heat from the back. So the front face is the sealed one — modules are glue-potted and the cabinet front is closed against weather — while the rear stays serviceable, with airflow for the power supplies and receiving cards. When a screen is flush-mounted against a billboard frame, a front-service layout lets technicians swap a module from the outside without pulling the screen down.
Module
P4 Outdoor LED Module: 320×160 mm 1921 Black-Lamp Board
The heart of this screen is the 320×160 mm outdoor P4 module — 80 columns by 40 rows of pixels, driven by 60 ICs with 1921 black lamps. This module data comes from the factory price list; the 10S scan figure is referenced from the outdoor flexible-board line in the same database, so it is marked accordingly below.
| Parameter | Specification |
|---|---|
| Module size | 320×160 mm (confirmed) |
| Resolution | 80×40 px — 3,200 pixels (confirmed) |
| Pixel density | 62,500 px/m² (derived) |
| Scan mode | 10S (typical — referenced from flexible outdoor line) |
| Driver ICs | 60 ICs per module (confirmed) |
| Lamp beads | 1921 SMD black lamps (confirmed) |
| Sealing | Glue-potted/encapsulated module face against moisture (typical) |
Why black lamps matter in daylight
Outdoor screens fight daylight twice: they must be bright enough to win the sun, and the panel surface must not wash out the image when the screen is off or dim. Black (blackened-surface) 1921 lamps absorb ambient light instead of reflecting it, which lifts perceived contrast sharply compared with white-case lamps of the same brightness. On a billboard viewed from 4–8 m the pixels are still fine enough that this contrast gain is what keeps text edges clean against a bright sky.
Power & Control
P4 Outdoor LED Display Power Supply and Control System
An outdoor wall runs 24/7 in sun, rain and heat, so its electrical spine matters as much as the LEDs. Excel LED wires every outdoor screen with surge-protected switching power supplies, redundant signal paths and NovaStar, Huidu or Colorlight receiving cards matched to the pixel count — the same controller brands used across the indoor line, which keeps your spare stock and training unified.
Power, sized to the sun
Brightness target decides consumption: a high-brightness-class screen idles bright and pulls more than the same screen dimmed for night mode. A P4 wall is inherently lighter on power than finer outdoor pitches — fewer pixels and fewer lamps per square meter — and Excel LED quotes peak and average wattage per BOM so you can size feeders, UPS and cooling honestly. Every quote includes automatic brightness control that dims the wall at night, which typically cuts average power by 30–50% compared with running full brightness around the clock.
How many receiving cards does a P4 wall need?
Receiving-card count follows pixels and signal distance, not a fixed per-module rule. As a working rule, one receiving card comfortably handles several 320×160 modules in a row; wide billboards add cards to keep data cables short and refresh clean. Send the final wall size to engineering and the BOM will state exact card count, model and cabling topology — no guesswork at install time.
Features
Features of P4 Outdoor LED Screen Walls
Every feature below answers one outdoor problem: sun glare, rain, heat, dust, or the cost of climbing a billboard to repair. If a feature does not map to a problem, it does not earn its place on this page.
Billboard-class density
62,500 px/m² resolves large text and graphics cleanly from 4 m out — no wasted pixels at roadside distance.
Rain & dust sealing
Sealed module faces and gasketed cabinets shrug off rain, salt spray and sand.
High contrast
1921 black lamps cut reflected glare, keeping black levels deep on a bright facade.
Outdoor scan economy
60 ICs drive 3,200 pixels in a 10S sweep (typical) — a proven high-brightness outdoor arrangement.
Surge protection
Protected power input and signal ports reduce lightning and mains damage risk.
Front- or rear-service
Layout chosen per mounting — swap modules without dismantling the wall.
Product Matrix
P4 Outdoor LED Display Product Matrix: 10S 60-IC Configuration
Excel LED offers three fixed outdoor small-pitch modules; the table below compares the confirmed factory rows so you can position the outdoor P4 against its siblings before requesting a quote.
| Parameter | P2.5 Outdoor | P3.076 Outdoor | P4 Outdoor ★ |
|---|---|---|---|
| Module size | 320×160 mm | 320×160 mm | 320×160 mm |
| Pixels / module | 128×64 = 8,192 | 104×52 = 5,408 (confirmed) | 80×40 = 3,200 (confirmed) |
| px/m² | 160,000 | ≈105,700 | 62,500 |
| Scan / ICs | 16S · 48 ICs | 13S · 84 ICs | 10S · 60 ICs (typical/confirmed) |
| Lamp beads | 1415 | 1415 (confirmed) | 1921 (confirmed) |
| Best viewing distance | ≈2.5 m and up | ≈3 m and up (typical) | ≈4 m and up (typical) |
| Typical use | Storefront & close-view ads | Street-level & mid-zone | Billboards & long-zone |
| Sharpness per €/m² | Highest pixel value | Balanced sweet spot | Most economical |
Viewing distance is the deciding filter. If the closest viewer is 2.5–4 m away, the P2.5 outdoor LED display carries the most pixels; from 3 to 6 m the outdoor P3.076 LED display is the balanced pick. Once viewers sit beyond about 4 m — billboards, roadside sites, facade media — the P4 outdoor wall delivers the same perceived sharpness at the lowest per-square-meter price in the family.
Comparison
Outdoor P4 vs Indoor P4 LED Display: What Really Changes
Both screens share the same 4 mm pitch, but “same pitch” is where the similarity ends. Buyers frequently compare an outdoor quote against the indoor one, so here is the honest difference in parts, brightness and price.
| Item | Outdoor P4 ★ | Indoor P4 |
|---|---|---|
| Brightness | High-brightness class, sunlight-readable (typical) | 1,000–2,000 nits class (typical) |
| Weather sealing | IP65 front, sealed modules | None — indoor air only |
| Lamp beads | 1921 black lamps (confirmed) | 2020 SMD, 1515 option (confirmed) |
| Scan / ICs | 10S · 60 ICs (typical/confirmed) | 20S · 30 ICs (confirmed) |
| Cabinet | Steel / die-cast alu, weatherproof | 640×480 mm die-cast aluminium, 6-module (typical) |
| Per-m² price | Higher — lamps, sealing, structure | Lower |
| Best for | Billboards, roadways, sunlit sites | Retail, transport hubs, event halls |
Three parts explain most of the price gap: outdoor-rated lamp beads (1921 black lamps built for wider temperature and humidity), module and cabinet sealing, and sun-fighting brightness — an outdoor module draws more power and sheds more heat than its indoor twin. If your screen sits under a roof or glass, read the indoor P4 LED display page and save the outdoor premium for real weather.
Use Scenarios
Where a P4 Outdoor LED Display Earns Its Economy
Roadside billboards and DOOH panels
Roadside advertising is read from vehicles — viewers 5–15 m from the face, moving, in full sun. A P4 outdoor screen turns a static billboard panel into content that rotates by the minute, and its 62,500 px/m² keeps headline text and brand colors legible at that distance without paying for pixels no one can see. It is the standard spec for digital roadside DOOH panels that sell ad time by the frame.
Building facades and rooftop media
Facade screens are seen from across the street or the next block — rarely closer than 4 m, often 10 m plus. P4 density matches the distance: content reads cleanly, the panel costs materially less per square meter than a P3.076 or P2.5 face of the same size, and lower pixel density reduces both power draw and heat load inside the cabinet stack — a real saving on a large facade.
Parking lots, forecourts and drive-throughs
Drivers read signage from queues and aisles — 4–10 m away, through glass, often in glare. A high-brightness P4 wall holds message legibility across that whole band, and auto-dimming cuts the electricity bill at night when the lot is empty. Larger pitch would blur the small print; finer pitch would spend money on detail the windshield never shows.
Sports venues and public event screens
Outdoor event and stadium perimeter screens are viewed from stands and open areas — precisely the 4 m-and-beyond band where P4 density is invisible from the difference to finer pitches but very visible in the quote. High-brightness output holds the image in daylight, and the sturdy weatherproof build takes the festival season’s dust and rain in stride.
Buying Guide
How to Choose the Right P4 Outdoor LED Display
- Confirm the closest viewing distance. Walk to where the closest real viewer stands. At 4–8 m, P4 is the value pick; under about 3 m consider the P3.076 or P2.5 outdoor wall; beyond 8 m with only large-type content, step down to P5/P6 and spend the savings on size.
- Map sun and shade hours. A south-facing billboard in full sun needs the high-brightness option; a shaded facade can step down and cut both capex and power draw.
- Choose front- or rear-service before mounting. Flush wall mount → front service. Structure with walk-in space behind → rear service. This decision changes the cabinet frame and the install scope.
- Plan content and control early. Media player, sending card and signal topology come from the wall’s pixel count — a 9.6×4.8 m P4 wall is roughly 2,400×1,200 pixels and needs the controller sized for it.
- Ask for the full BOM, not a screen price. A real quote lists modules, cabinets, power, receiving cards, spare ratio (5% spares is a sensible default) and shipping terms.
What drives the price of a P4 outdoor LED screen
Five levers move the quote: lamp bead grade and brand (1921 black lamps in leading brands cost more and drift less), cabinet material and tolerance (die-cast aluminium beats folded steel for flatness and serviceability), brightness target, refresh and chip grade, and spares, shipping and install scope. Position in the family, from recent Excel LED projects: an outdoor P4 wall typically lands below the outdoor P3.076 and outdoor P2.5 price per square meter and above the larger outdoor pitches, and carries an outdoor premium over its indoor P4 twin for the lamp, sealing and structure upgrades — before any customs, freight or install work.

Resolution Guide
P4 Outdoor LED Display: Resolution and Viewing Distance Math
Resolution is simple with 320×160 mm modules: every 320 mm of width and 160 mm of height adds one module column or row, and each module contributes 80×40 pixels.
Viewing distance guides pitch choice, not the other way around. At 4–8 m the eye no longer resolves the difference between 4 mm and 3.076 mm detail, so P4 outdoor earns its lower price; step closer than about 3 m and the finer pitches win. Our fine pitch LED display hub explains the pitch-vs-distance logic for indoor walls — the same table applies outdoors once brightness and sealing are satisfied.
Closing Note
P4 Outdoor LED Display — the Economy Leader of Fixed Outdoor Walls
Why choose an Excel LED outdoor P4 screen
You get a single-factory BOM: confirmed 320×160 mm modules with 1921 black lamps, 60 ICs and a 10S reference scan; IP65-sealed cabinets; surge-protected power; matched NovaStar/Huidu/Colorlight control; 72-hour aging and luminance calibration before packing. One supplier owns quality from lamp to bracket, which is what keeps a billboard alive for a decade of sun, rain and thermal cycles.
Maintenance method for outdoor P4 screens
Routine (front or rear, per layout)
Monthly: visual scan for dead pixels and sealant damage, check drainage holes are clear. Quarterly: inspect power and signal connectors, re-torque exposed fasteners, clean the face with a soft damp cloth when dust builds. Half-yearly: thermal camera or hand check of power supplies, review brightness uniformity after cleaning.
Component-level
Swap a failed module from the service side by releasing its catches, unplugging the data/power tails and fitting the spare — a trained technician typically replaces one in minutes. Keep a 5% spare ratio of modules plus spare power supplies; store them in a dry room, and the wall never waits on freight for a single failure.
Packaging of P4 outdoor LED displays
Modules ship in reinforced cartons with EPE foam pockets; cabinets travel on wooden skids or flight cases with corner protectors for project cargo. Excel LED marks crates for fork-lift and lay-flat handling, and each screen ships with its wiring diagram, spare list and calibration report so site crews can commission without guesswork.
FAQ
Frequently Asked Questions About P4 Outdoor LED Displays
Q1 How bright does a P4 outdoor LED display need to be?
An outdoor P4 LED display should run in the high-brightness class — roughly 5,500 nits and up, depending on the configuration — so content stays readable in direct sunlight. In practice Excel LED quotes the brightness target first, then dims the wall automatically at night, which cuts power use and keeps the image comfortable in darkness.
Q2 Can a P4 LED display really work outdoors in the rain?
Yes, when it is built for it. An outdoor P4 screen uses sealed modules and cabinets rated around IP65 on the front face, with treated frames and drainage so water sheds instead of pooling. The key is buying an outdoor-rated product, not a converted indoor screen — sealing, lamps and structure are different parts, not accessories.
Q3 What is the difference between indoor and outdoor P4 LED screens?
Same pitch, different products. Outdoor P4 uses high-brightness black 1921 lamps, sealed IP65-class modules and weatherproof cabinets, while indoor P4 runs 1,000–2,000 nits with 2020 SMD lamps and a 640×480 mm die-cast aluminium cabinet. The outdoor build costs more per square meter because lamps, sealing and structure are all tougher.
Q4 How many pixels are on a 320×160 outdoor P4 module?
A 320×160 mm outdoor P4 module holds 80 columns by 40 rows — 3,200 pixels in total — which works out to 62,500 pixels per square meter. That density is why headline text and logos stay sharp when viewers stand four meters or more from the wall.
Q5 What lamp beads does an outdoor P4 module use?
The confirmed factory configuration uses 1921 SMD black lamps. The blackened lamp case absorbs ambient light instead of reflecting it, which lifts perceived contrast in daylight — an important advantage on billboards where bright sun can otherwise wash the panel into a grey blur.
Q6 What does 10S scan mean on an outdoor P4 module?
10S means the module drives its 40 pixel rows in 10 time-shared sweeps; the outdoor P4 board carries 60 driver ICs for that job. Scan choice balances drive strength, IC cost and power draw, and 10S is the common outdoor arrangement for high-brightness boards, noted here as a reference figure.
Q7 What is the best viewing distance for a 4 mm outdoor screen?
Plan for a closest viewer around 4 m and beyond. Under about 3 m, individual pixels start to resolve and an outdoor P3.076 or P2.5 wall becomes worth the money; the density advantage of those finer pitches fades quickly past 4–6 m, which is where P4 outdoor delivers the same perceived sharpness for less.
Q8 How much does a P4 outdoor LED display cost?
Position in the family tells the story: outdoor P4 typically costs less per square meter than outdoor P3.076 and outdoor P2.5, more than the larger outdoor pitches, and it carries an outdoor premium over the indoor P4 equivalent because lamps, sealing, brightness and structure cost more. The final figure depends on lamp grade, cabinet material, brightness, refresh, size and shipping; Excel LED quotes the full BOM for each project.
Q9 P4 outdoor vs P3.076 outdoor: which LED display should I choose?
Measure the closest viewing distance. At 3–6 m, the P3.076 outdoor wall’s ≈105,700 px/m² keeps text and logos sharp; beyond about 4 m, P4’s 62,500 px/m² looks the same to the eye at a lower per-square-meter price. The typical rule: P3.076 for street-level and mid-zone content, P4 for billboards and long viewing bands.
Q10 How long does an outdoor P4 LED screen last?
LED lamps are rated for roughly 100,000 hours, but an outdoor screen’s real life is set by its weakest part — power supplies, seals and ventilation in hot climates. Built with derated power and proper drainage, an Excel LED outdoor wall typically serves 7–10 years before noticeable brightness drift, with module swaps extending that window.
Q11 How is a P4 outdoor LED display installed and serviced?
Most installations use a steel structure engineered for wind load, with the screen hung or bolted to it. Flush billboard mounts favor front-service cabinets; structures with rear walk space allow rear service. Site work covers anchoring, power with surge protection, signal routing and commissioning, and Excel LED provides drawings plus remote or on-site guidance.
Q12 What warranty comes with your outdoor P4 display?
Excel LED backs outdoor P4 displays with a standard 2-year warranty on parts and workmanship, covering lamp failures, driver ICs and power supplies under normal use. Warranty support includes remote diagnosis and spare-part dispatch; extended terms can be discussed for project-scale orders.
