What is the P4 Outdoor LED Display?
A P4 outdoor LED display is an outdoor LED screen with a 4mm pixel pitch. It offers a good balance between image clarity and project cost, making it one of the most widely used pixel pitches for outdoor applications.
With a brightness of 5500–8000 nits, IP65 waterproof protection, and a refresh rate of up to 3840Hz, P4 outdoor LED displays can operate reliably in various outdoor environments while delivering clear and stable images.
How We Help Ensure Reliable P4 Outdoor LED Display Projects
Premium LED chips
We use branded LED chips with good batch consistency. Brightness and color stay uniform across the screen, so color difference is not a problem over time.
Strict QC
For the same order, we use only one LED bin. Brightness deviation across the screen is kept within ±5%, and color difference ΔE is less than 3. You won’t see any noticeable difference with your own eyes.
72-Hour Aging Test
Each batch runs continuously for 72 hours before shipping. This helps catch early failures at the factory, so the screens you receive are more reliable.
Supports Front Maintenance
You can replace modules and components from the front. If the screen is wall-mounted, no rear access space is needed. If a module fails, just pull it off with a suction tool. The rest of the screen stays on. Putting a new module in place takes about 10 seconds.
Technical Support
We offer remote engineer support and video guidance. Engineers can check issues remotely on the same day, or guide you step by step through a video call. A dedicated engineer follows your project from start to finish, so you don’t have to explain your situation to different people each time.

Energy Saving P4 Outdoor LED Display
This Outdoor P4 LED Display uses a common cathode design to reduce power consumption and operating costs. Compared with conventional outdoor LED displays, average power consumption is typically 50 to 80 watts lower per square meter. For large advertising screens operating long hours each day, this can significantly reduce annual electricity expenses.

P4 Outdoor SMD LED Display
This P4 outdoor LED screen uses SMD LED technology. Compared with DIP LEDs, the viewing angle is wider, so the picture remains clear when viewed from different positions. The SMD structure also helps reduce the risk of LEDs loosening during transportation and installation. It is commonly used for outdoor advertising displays, commercial LED screens, and outdoor led signage projects.

P4 Outdoor DIP Full-color LED Display
This P4 LED display is designed for locations with strong wind and demanding outdoor conditions. Compared with SMD LED screens, DIP LEDs provide better resistance to vibration and wind pressure, helping improve stability in outdoor installations. It is commonly used for highway billboards, roadside advertising displays, rooftop LED screens, and other projects installed in open outdoor areas.

P4 Outdoor Die-cast LED Display
This P4 outdoor LED display offers better cabinet flatness and a more seamless visual appearance when multiple cabinets are connected together. Compared with traditional steel cabinets, it is lighter in weight and provides better heat dissipation. The one-piece die-cast structure also improves overall stability, helping the screen maintain reliable performance during long-term outdoor operation.

Over 8000 nits of brightness, visible from far away. Suitable for perimeter screens, center-hung displays, and upper-stand screens.
Commercial Real Estate & CorporateThis P4 outdoor LED screen is used in shopping malls, retail centers, hotels, and office towers. Common installation locations include building facades, plaza digital signage, and event promotion areas. The screen features a seamless splicing design, so when multiple panels are joined together, there are no black gaps; the entire display looks like one single piece.
Government & Public ProjectsThis outdoor digital display is used in city plazas, train stations, and airports for public announcements and information. It supports 24/7 continuous operation with an industrial-grade power supply and cooling design, keeping the failure rate low. The lifespan is about 100,000 hours; if you run it 10 hours a day, it can last more than 10 years.
Events & Stage RentalThis rental LED screen is used for concerts, music festivals, exhibitions, and temporary outdoor events. Quick-lock connectors help reduce installation and dismantling time. The die-cast aluminum cabinet makes transportation easier, while the cabinet structure is designed for repeated assembly and rental applications.
How To Choose The Right P4 Outdoor LED Display
Outdoor advertising displays usually operate under direct sunlight for long periods. A brightness level above 8000 nits helps keep images visible during the day. The 960×960mm cabinet is commonly used for digital billboards because it reduces installation time and requires fewer cabinet connections.
Stadium LED screens are often used for live broadcasts, score displays, and sponsor advertising. A refresh rate of 3840Hz or higher helps reduce flicker when content is recorded by cameras. This configuration is commonly used for sports LED displays and perimeter LED boards.
Commercial facade LED screens are usually installed directly on building walls. A front maintenance LED display allows modules and power supplies to be serviced from the front, eliminating the need for a maintenance corridor behind the screen.
Government LED displays and public information displays often require long operating hours and high system reliability. A redundant power supply helps keep the screen running if one power supply stops working. CE, FCC, and RoHS certifications are commonly required for public bidding projects.

Real P4 Outdoor LED Display Projects Worldwide

An 8m × 4m outdoor advertising display is installed beside a highway. The customer needed it to stay visible under direct sunlight. We used a P4 digital billboard with 7000 nits of brightness. After installation, the ads stood out much more. The customer said the visibility improved significantly.

Two outdoor LED screens measuring 5m × 4m were installed on the shopping mall facade. The customer wanted the screen to be bright during the day but not too bright at night. We added ambient light sensors for auto brightness. After a year and a half, there were no blackouts and no dead pixels.

A full ring around the field — 60 m long by 0.8 m high. On game days, it shows sponsor ads and live scores. We used a P4 sports LED display with an IP65 waterproof rating. It ran for one full season — 38 matches, averaging 6 hours per match. It went through three heavy rainstorms with no water getting in. The display stayed stable the whole time. The customer said it is way better than their previous screen.

An airport LED display in the arrival hall, 12 meters by 4 meters. It is a flight information display that needs to run 24/7 with no blackouts. We used a redundant power supply and industrial-grade cooling. After 14 months, there were no blackouts and no dead pixels. The customer said it is very reliable.

Packaging
We use flight cases or plywood boxes depending on the outdoor LED display size and shipping method. Cabinet corners are fitted with protective edges. Foam padding is placed between modules. Power supplies, control cables, and spare modules are packed separately in small boxes so they don’t move around inside. We take photos and videos before shipping and send them to you for confirmation.
Transparent Lead Time
We keep stock of standard-size P4 outdoor LED screens and can ship within 5 days after order confirmation. For custom outdoor LED displays, delivery usually takes 15 to 20 days. Once the order is confirmed, we will give you a specific ship date. During production, we will send you photos after each key step. We work with freight forwarders experienced in shipping LED displays to the US, Europe, the Middle East, and Southeast Asia. You can also use your own forwarder, and we will cooperate with them for shipment.
Real Feedback from Global P4 Outdoor LED Display Projects
The brightness of a P4 outdoor LED Display is usually between 5500 and 8000 nits. At this level, the screen stays visible even under direct sunlight. If the screen is installed in a shaded area or a location with less light, you can lower the brightness to save power and reduce light pollution.
The ideal viewing distance for a P4 outdoor LED display is 4 to 20 meters. Within this range, the outdoor LED screen provides clear images, and individual pixels are generally not noticeable. At viewing distances shorter than 4 meters, the pixel structure may become visible. For distances beyond 20 meters, a larger pixel pitch LED display may be a more practical choice.
Yes. If you choose the front maintenance outdoor LED screen, you can mount it directly against the wall with no rear access space needed. Modules, power supplies, and receiver cards can all be replaced from the front. As long as the wall can support the weight, rear space is not a concern. This works well for building facades, columns, and other outdoor LED display installations with limited space.
We offer a 2-year warranty for all P4 outdoor LED displays from the ship date. If a module has dead pixels, color shift, or stops working during the warranty period, we send you a replacement for free. You do not need to ship the faulty one back. Power supplies and receiver cards are also covered for 2 years.
When we ship your order, we include 5% spare LED modules and commonly used spare parts. For example, if you buy 100 modules, we add 5 extra ones. If a module fails on site, you can replace it with a spare right away without waiting for us to send a new one.
Yes, the P4 outdoor LED screen has an IP65 rating. It is designed for outdoor LED display installations exposed to rain and dust. Normal rain or heavy rain will not cause water to get inside. However, do not soak the screen in water or aim a high-pressure water gun at the gaps. During installation, make sure the junction boxes are properly sealed, and the rubber strips between cabinets are pressed tight. For daily cleaning, use a damp cloth. Do not spray water directly onto the front of the screen.
It really comes down to how big your screen is and how you plan to install it.
960×960mm cabinets are for large billboards, building facades, rooftop screens, and outdoor advertising displays. Bigger cabinets mean fewer of them. So you install faster and get fewer seams. You usually need a crane or a steel frame. Highway billboards — almost all of them use these large cabinets.
500×500mm cabinets are for small screens or custom shapes, such as curved walls, column wraps, or rental events. One person can carry one. No need for a second set of hands. Mid-sized roadside billboards — many of them use this size.
500×500mm cabinets are for small screens or custom shapes — curved walls, column wraps, rental events. Smaller cabinets are more flexible. Corners are easier to handle. If you want a cylindrical screen or a wave-shaped wall, you need these small cabinets.
Simple rule: Big area, big cabinet — faster install. Small area or custom shape, small cabinet — more flexible.
Send us your dimensions. We will figure out which size gives you the least material cost and the easiest install.
Both have a 4mm pixel pitch. But the outdoor and indoor versions are built completely differently. Three main differences:
Brightness
P4 outdoor LED screens run 5500 to 8000 nits. They stay visible under direct sunlight. P4 indoor LED screens run 800 to 1200 nits. That’s fine for conference rooms, lobbies, and shopping mall atriums. Take an indoor screen outside, and at noon you won’t see a thing.
Water and dust protection
Outdoor LED displays are IP65 rated. They can take rain, dust, and moisture. Indoor screens are not waterproof. Not a single drop. Install an indoor LED display on a building facade, and one heavy rainstorm will kill it. We have seen too many cases like this.
Cooling and cabinet
Outdoor cabinets use die-cast aluminum or steel with cooling fins. They shed heat even under the sun. Indoor cabinets are thin with no cooling. Leave them outside for two summers, and LEDs start dying in large numbers.
In short, Outdoor screens are made for rain, sun, wind, and temperature swings. Indoor screens must stay inside — no water, no sunlight, no wind.
Not sure where your screen will go? Just tell us the location. We will pick the right type. Exterior walls, rooftops, highway signs, stadium perimeter — go outdoors. Lobbies, conference rooms, shopping mall atriums, exhibition halls — go indoors. Get it wrong, and it’s not a matter of repair. It just won’t work at all.
There is no fixed size limit for a P4 outdoor LED display. As long as the wall or steel frame can support the weight, additional cabinets can be added to increase the screen size.
The largest project we have supplied was 200 meters long and 12 meters high, with a total area of 2,400 square meters. It was installed along a highway as an outdoor advertising billboard.
Only two limits:
First, how much weight the wall or steel frame can hold. If the steel frame is too weak, the screen will sag or even fall off. We will calculate the steel structure for you. You don’t have to figure it out.
Second, your budget. A larger outdoor LED screen requires a stronger steel frame, more power supplies, and additional receiver cards. The cost from 100 square meters to 1,000 square meters is not 10 times — it’s more. Long-distance cabling and larger power distribution boxes add up.
What you need to do: Send us your installation dimensions and site photos. We will tell you the maximum size, how to build the steel frame, and how to size the power supply. No guessing. No asking around.
Yes, we do.
We will send you CAD drawings and wiring diagrams. The drawings show how to build the steel frame, mount the screen, and connect the cables. Your local crew can follow the drawings to install the screen.
If you run into issues during installation, our engineers can guide you through a video call. We can also send you an installation step document in advance if needed.
Yes, it can.
The P4 outdoor screen has a brightness of 5500 to 8000 nits, so the image stays clear even under direct sunlight. The screen also has an anti-glare coating and black masks on the surface to reduce reflection. You do not need to add a sunshade or extra cover.
One small detail to keep in mind: try not to install the screen facing directly into low-angle sunset light for long periods. For example, a south-facing wall is fine. But if the screen constantly faces the setting sun, there may be some reflection. Adjusting the installation angle can solve this.
Screen body includes modules, cabinets, power supplies, and receiver cards. Cabinet sizes are 960×960mm or 500×1000mm.
The control system includes a NovaStar sending card, receiving cards, and one video processor.
Cables include network cables and power cables. Both are pure copper and meet national standards. The length is based on your installation distance.
Spare parts include 5% spare modules of the total order quantity.
Steel structure – we provide CAD drawings. You hire local workers to build it.
Packaging can be flight cases or plywood boxes.
Installation support includes CAD drawings, video tutorials, and remote video guidance from engineers.
Quotation list – every item and quantity is clearly listed. If anything is missing, we help complete the list.

Notes:
Larger outdoor LED displays usually have a lower price per square meter.
Front maintenance, curved LED displays, and custom outdoor LED screens typically cost more than standard configurations.
The LED display price also depends on brightness, refresh rate, cabinet material, and control system selection.
For an accurate quotation, please provide the screen size, installation location, and project requirements. We will send you a detailed P4 outdoor LED display quotation within 12 hours.
The price of a P4 outdoor LED display is mainly affected by the configuration and the installation requirements.
A screen installed on a highway billboard usually costs more than one installed under a canopy. The reason is that direct sunlight requires higher brightness, and higher brightness means a higher cost.
The refresh rate also affects the price. For a normal outdoor LED advertising screen, 1920Hz is usually enough. If the screen will be filmed by cameras, such as a stadium perimeter screen or a live event display, 3840Hz is the more common choice.
Cabinet material makes a difference as well. Most fixed outdoor LED screens use steel cabinets because the cost is lower. Rental LED screens are more likely to use die-cast aluminum because the cabinets are lighter and easier to transport.
The control system is another factor. A single billboard can work well with a standard control card. If several screens need to run together, or the project requires remote management, NovaStar is often selected.
Screen size affects the unit price. In most cases, a 100-square-meter LED billboard costs less per square meter than a 10-square-meter screen with the same configuration.
Custom work also increases the cost. Curved screens, corner displays, column wraps, and non-standard cabinet sizes require additional production and installation work.
Some optional features add to the budget as well. Front maintenance, redundant power supplies, ambient light sensors, and flight cases all increase the total project cost.
The LED chip, power supply, and driver IC also affect the final quotation. This is why two P4 outdoor LED displays of the same size can have very different prices.
