1. What Is P4 LED Screen?
When people mention a P4 LED screen, they’re simply referring to a display with a 4mm pixel pitch — the distance from one pixel to the next. This spacing is tight enough to show clear details, especially when the viewer is standing a few meters away, but not so fine that it pushes the cost too high.
P4 sits in a comfortable middle ground. It’s sharper than larger‑pitch options and doesn’t demand the budget of P2 or P2.5 displays. Because of that, it’s often used in places like retail areas, event stands, meeting rooms, and other environments where the audience is neither too close nor too far.
In short, P4 works well for most general-purpose content: readable text, presentations, product visuals, and everyday video playback — all without stretching the budget unnecessarily.
Standard P4 LED module (320mm × 160mm)
To better understand it, let’s look at a standard P4 LED module.
A common module size is 320mm × 160mm, and within this area, you’ll typically find 80 pixels across and 40 pixels down — that’s 80 × 40 = 3200 pixels, or what the industry often refers to as “dots.” Each of these dots is a full-color LED pixel. These modules are the building blocks of a larger display, pieced together like tiles to create custom screen sizes.
But how many pixels are there per square meter?
Here’s the simple formula to calculate pixel density:
Pixel Density (pixels/m²) = (1000 ÷ Pixel Pitch in mm)²
For P4 LED screen:
(1000 ÷ 4)2 = 250 × 250 = 62,500 pixels/m²
That’s 62,500 pixels packed into every square meter — enough to display high-definition content clearly at a comfortable viewing distance of 4 to 15 meters.
This balance of resolution, modularity, and visual impact makes P4 LED screen a smart choice for events, advertising, public displays, and even indoor signage. It’s not ultra-fine like P2.5, but not rough like P6 either — it’s the just-right middle ground that delivers clarity without blowing your budget.
2. Types of P4 LED Screens
Not all P4 LED screens are built the same. Depending on where and how you plan to use them, there are several types you can choose from — each designed to shine in its own environment.
(1) P4 Indoor LED Screen
This is a popular choice for retail spaces, conference rooms, studios, and churches. With high contrast, quiet operation, and vivid colors, p4 indoor LED screen delivers sharp visuals at close range. It typically comes with front maintenance access, making it easy to install in tight indoor spaces.
Indoor models often use high-resolution SMD modules with a standard size of 320×160mm and a pixel matrix of 80×40. These modules are designed for front maintenance, which makes installation easier in wall-mounted or embedded setups.
(2) P4 Outdoor LED Screen
Built to battle the elements, p4 outdoor LED screen is waterproof, dustproof, and bright enough to be clearly visible even in sunlight. With an IP65 or higher rating, it’s perfect for outdoor advertising, event stages, and building facades. If your display needs to brave wind and rain, this is your go-to.
Outdoor modules typically feature high-brightness LEDs and reinforced housing, often equipped with rear waterproof seals and robust mask designs. The standard P4 module (320×160mm) here supports ≥6000 nits brightness, ensuring clarity under direct daylight.
(3) P4 Flexible LED Display
Looking to wrap your screen around a column or create a curved video wall? A flexible P4 option bends to your needs — literally. These are made with soft PCB materials, ideal for creative installations in shopping malls, museums, and architectural facades.
These modules use soft PCB and silicone frames instead of rigid materials, allowing them to conform to curved surfaces or creative 3D structures. Despite the flexibility, the pixel pitch and resolution remain consistent with standard P4, ensuring visual clarity.
(4) P4 Rental LED Screen
If you’re planning events, concerts, or roadshows, a P4 LED screen rental is lightweight, durable, and quick to assemble. These panels use fast locks and flight cases, making transport and setup a breeze.
Rental-type modules are typically built into die-cast aluminum cabinets with quick-lock systems and replaceable LED modules, often using the same 320×160mm format. Their modular design enables fast replacement and efficient cable management, perfect for time-critical event setups.
3. P4 LED Screen Resolution and Specifications
Understanding the specs behind P4 LED screen helps you make smarter buying decisions. Let’s break down what resolution means, how it’s calculated, and what other specs to expect.
What Does P4 Mean for Resolution?
The “4” in P4 refers to a 4mm gap from one LED point to the next. When the spacing is tighter, more diodes are packed into the same screen size—delivering sharper, more detailed visuals.
Screen Resolution = (Horizontal Modules × Pixels per Module) × (Vertical Modules × Pixels per Module)
Example: 6×4 P4 modules (each 80×40 pixels):
(80 × 6) × (40 × 4) = 480 × 160 pixels
How to Calculate Resolution of P4 LED Screen
Here’s a simple way to calculate the resolution:
Formula:
Horizontal pixels = Screen width (mm) ÷ 4
Vertical pixels = Screen height (mm) ÷ 4
For example:
A 4000mm (4m) × 3000mm (3m) P4 screen:
4000 ÷ 4 = 1000 pixels (width)
3000 ÷ 4 = 750 pixels (height)
Resolution: 1000 × 750 pixels
This resolution offers a crisp display, especially when the audience is at least 4 meters away.
