When purchasing an outdoor LED display, many buyers compare different pixel pitches before making a final decision.
Among common outdoor advertising solutions, P4 and P5 LED displays are two popular choices for commercial advertising, shopping malls, transportation areas, and public spaces.
At first glance, the difference between P4 and P5 seems simple:
P4 = higher resolution
P5 = lower cost
However, choosing between them requires more consideration.
The right choice depends on:
Viewing distance
Screen size
Content type
Installation environment
Budget
Maintenance requirements
A smaller pixel pitch does not always mean a better project result.
Based on our experience supplying outdoor LED displays for advertising companies and system integrators, selecting the correct balance between image quality and investment is usually more important than choosing the highest specification.
What Is The Difference Between P4 And P5 Outdoor LED Display?
The main difference is pixel pitch.
Pixel pitch refers to the distance between two adjacent LED pixels.
P4 Outdoor LED Display
Pixel pitch:
4mm
Pixel density:
Higher
Resolution:
Higher
Recommended for:
Medium viewing distance
Commercial advertising
Shopping mall areas
Retail environments
P5 Outdoor LED Display
Pixel pitch:
5mm
Pixel density:
Lower compared with P4
Resolution:
Slightly lower
Recommended for:
Larger outdoor advertising screens
Roadside applications
Public spaces
Resolution Comparison Between P4 And P5
For the same screen size:
Example:
Screen size:
5m × 3m
P4 Resolution
Width:
5000 ÷ 4 = 1250 pixels
Height:
3000 ÷ 4 = 750 pixels
Resolution:
1250 × 750 pixels
P5 Resolution
Width:
5000 ÷ 5 = 1000 pixels
Height:
3000 ÷ 5 = 600 pixels
Resolution:
1000 × 600 pixels
P4 provides approximately 56% more pixel density compared with P5.
This difference becomes visible when:
viewers stand closer
displaying text
showing product details
playing high-resolution videos
Viewing Distance: The Most Important Factor
Many buyers make the mistake of choosing pixel pitch first.
A better approach is:
Viewing distance → Pixel pitch → Resolution → Budget
General recommendation:
| Pixel Pitch | Recommended Viewing Distance |
|---|---|
| P4 | 4-20 meters |
| P5 | 5-25 meters |
| P6 | 6-30 meters |
| P8 | 8-40 meters |
When Should You Choose P4?
P4 outdoor LED display is suitable when:
Audience is relatively close
Content contains detailed images
Text readability is important
Screen size is moderate
Typical applications:
Shopping Mall Advertising
Visitors may stand within several meters.
P4 provides smoother images for:
Brand videos
Product advertisements
Promotional content
Commercial Building Facades
For premium commercial projects, higher resolution can improve visual quality.
Outdoor Retail Advertising
Stores often need clear product images and promotional videos.
When Should You Choose P5?
P5 outdoor LED display is suitable when:
Viewing distance is longer
Screen size is larger
Budget efficiency matters
Typical applications:
Roadside Advertising
Drivers usually view the screen from a distance.
A P5 display can provide sufficient clarity while reducing project cost.
Outdoor Public Information Displays
Examples:
Transportation areas
Community advertising
Public squares
Large Advertising Screens
For larger screens, P5 can achieve a good balance between:
investment
image quality
power consumption
Cost Difference Between P4 And P5
Generally, P4 outdoor LED displays cost more than P5 because they require:
More LED lamps per square meter
More driver ICs
Higher PCB density
More precise manufacturing
However, the initial purchase price is only one part of total cost.
Buyers should also consider:
Power consumption
Maintenance cost
Spare parts
Expected lifespan
A slightly cheaper display may not always create lower long-term costs.
Cost Difference Between P4 And P5
Because P4 contains more pixels per square meter, power consumption may be slightly higher compared with P5.
For large outdoor advertising projects operating many hours per day, energy efficiency becomes increasingly important.
Factors affecting power consumption include:
Brightness setting
LED efficiency
Power supply quality
Control system
Operating schedule
Factory Recommendation: How We Usually Choose Between P4 And P5
When customers ask:
"Which one should I buy, P4 or P5?"
We usually do not answer immediately.
Instead, we check:
Installation location
Viewing distance
Screen dimensions
Content requirements
Daily operating hours
For example:
A 4×3m advertising screen outside a shopping mall may benefit from P4.
A 10×6m roadside billboard may achieve better cost performance with P5.
The best solution depends on the project, not only the specification.
