P3 vs P4 vs P5: Which SMD Screen?
Choosing between P3, P4 and P5 is not simply about picking the smallest pixel pitch. The right option depends on viewing distance, screen size, content, environment and project budget.
Smaller Pitch Doesn't Always Mean Better.
P3, P4 and P5 describe the pixel pitch of an LED display. In simple terms, the number represents the approximate distance between pixels.
A smaller pixel pitch places pixels closer together and can provide greater pixel density across the same physical display. But the practical value depends heavily on how far people will stand from the screen.
For a large roadside billboard viewed from a considerable distance, P5 may provide an appropriate balance. For applications where viewers are closer to the display, P3 may offer advantages in perceived detail.
Don't ask only “Which pitch is better?” Ask “Which pixel pitch matches my viewing distance and application?”
See What Changes Between P3, P4 & P5.
The physical pixel arrangement is one of the main differences between these display categories.
P3
3 MMHigher pixel density compared with P4 and P5 for the same physical screen area.
P4
4 MMA commonly considered middle ground between finer detail and larger-pitch outdoor display requirements.
P5
5 MMA larger pitch that can make practical sense for larger screens viewed from greater distances.
P3 vs P4 vs P5 At a Glance.
Use this table as a starting point when discussing your project requirements with an LED display supplier.
| FACTOR | P3 | P4 | P5 |
|---|---|---|---|
| Pixel Pitch | 3 mm | 4 mm | 5 mm |
| Pixel Density | Higher | Medium | Lower |
| Detail at Close Distance | Higher potential | Good | Lower |
| Long Viewing Distance | Suitable | Suitable | Suitable |
| Large Outdoor Displays | Suitable | Suitable | Suitable |
| General Cost Direction | Higher | Mid-range | Lower |
| Best Selection Method | Viewing distance + application + screen size + budget | ||
Think About Viewing Distance.
Pixel pitch selection should be connected to the distance between the display and its regular audience.
Closer Audience
When viewers regularly stand closer to the display, finer pixel pitches can help create a denser image structure and smoother perceived detail.
Distant Audience
For displays primarily viewed from farther away, a larger pixel pitch may provide an appropriate practical balance between display size, image visibility and project cost.
Where Could Each Pitch Make Sense?
These are planning categories rather than strict rules. The final selection should consider the complete project.
Detail-Focused Outdoor
P3 may be considered when greater pixel density is important for the intended viewing conditions.
- Advertising displays
- Premium commercial screens
- Applications with closer viewers
- Detailed video content
Balanced Outdoor
P4 can be considered when a project needs a balance between display detail, physical area and budget.
- Commercial advertising
- Building displays
- Retail branding
- General outdoor content
Large-Format Outdoor
P5 may be practical where the screen is large and the majority of viewers are positioned farther from the display.
- Roadside advertising
- Large commercial displays
- Long-distance viewing
- Large outdoor campaigns
Your Final Quote Depends on More Than P3/P4/P5.
Two screens using the same pixel pitch can still have different project costs because the complete system specification may differ.
LED Modules & Cabinets
Module quality, cabinet construction, configuration and serviceability can influence the display hardware cost.
Control & Power
Sending systems, receiving cards, power supplies and related electronics form part of the complete LED display system.
Structure & Installation
Structural steel, mounting, wiring, labour, access and commissioning can affect the final project cost.
Before You Choose, Check These 4 Things.
A proper LED screen decision starts with the project, not with the product name.
How Far Away Are Viewers?
Estimate the normal and closest viewing distance.
How Large Is the Screen?
Physical dimensions affect both viewing experience and total hardware requirements.
What Content Will You Show?
Text, graphics, advertisements and video can have different practical requirements.
What Is Your Project Budget?
Use the required performance and application to establish an appropriate specification rather than choosing only by price.
Continue Your SMD Screen Research.
Once you understand pixel pitch, move to screen pricing, buying guidance and project-specific planning.
Still Unsure Between P3, P4 & P5?
Share your screen size, viewing distance, installation location and application with LUMAX. The right specification should be based on the complete project requirement.
Planning Note: P3, P4 and P5 are pixel-pitch categories and their suitability depends on application, viewing distance, screen dimensions, environment, content and system specification. The comparison above is intended as a general planning guide. Final LED display specifications and pricing should be confirmed according to the individual project.
