P3 and P4 LED walls are popular choices for LED displays due to their relatively small pixel spacing, making them ideal for background walls or video walls. These displays offer both decorative and functional viewing purposes, akin to using a television. The convenience they offer is noteworthy. But what exactly distinguishes an LED wall P3 from a P4? Which one is superior?
To comprehend the LED display specifics, it’s essential to understand the significance of “P” in P3 and P4. This knowledge helps in quickly responding to issues related to different product types.
If you pay attention, you’ll notice that all LED display types are named using a format where “P” is followed by a number and then “LED display”. For instance, P3 LED display or P4 LED display. This naming convention expands further into phrases like “P3 full-color indoor LED display” or “P4 outdoor rental LED display”.
After dissecting these phrases, it’s easier to understand the pattern. The “P” in P3 or P4 indicates the distance between the centers of two pixels (pixel spacing), and the number denotes the pixel distance, commonly referred to as point spacing.
This naming rule applies to LED walls as well since they are composed of LED screens. LED display walls with different point spacings can be created using corresponding modules, such as P3 LED modules forming a P3 LED wall, and similarly, P4 LED modules creating a P4 LED wall.
Because a P3 LED wall has smaller point spacing compared to a P4 LED wall, its display quality will be superior at the same viewing distance (for example, within 4 meters).
There are additional differences between P3 and P4 LED walls. Let’s explore these distinctions in more detail without further delay.
Difference between p3 and p4 LED wall
Let’s first look at the p3 p4 LED wall specifications and parameters of the two
Basic parameters of P3 LED display wall
| P3 LED Wall Specification Tables | |
| Dot spacing | 3mm |
| Module Size | 320 x 160mm |
| Module Resolution | 104 x 52 dots |
| Pixel density | 105625dots/㎡ |
| Drive mode | 1/13 scan |
| Average power consumption | 365W |
| Best viewing distance | 3~5M/㎡ |
Basic parameters of P4 LED display wall
| P4 LED Wall Specification Tables | |
| Dot spacing | 4mm |
| Module Size | 320 x 160mm |
| Module Resolution | 80 x 40 dots |
| Pixel density | 62500dots/㎡ |
| Drive mode | 1/10 scan |
| Average power consumption | 435W |
| Best viewing distance | 5~8M/㎡ |
Based on the given specification parameters, we can deduce several conclusions about P3 and P4 LED video walls:
Resolution Differences
The clarity of the displays is distinct. When comparing the same area and viewing distance, a P3 LED wall delivers a higher display resolution than a P4 LED wall.
Optimal Viewing Distances
Up to a 10-meter range, P3 offers superior display quality over P4. Beyond this distance, the difference becomes less noticeable. For cost-conscious decisions, P4 is more economical, but P3 delivers better effects for distances up to 20 meters.
Calculations show that the optimal viewing distance for P3 is between 3–6 meters. Viewing below 3 meters may reveal pixel granularity, necessitating a smaller pixel pitch display. For P4, the optimal viewing starts at 4 meters due to its larger pixel spacing, potentially showing graininess at closer distances.
If viewing distances are long, opting for a P3 screen may not be cost-effective as the enhancement in quality might not justify the higher expense.
Cost Variations
Despite the 1 mm difference between P3 and P4 spacing, applying this to a square meter results in 48,611 additional points for a P3 wall compared to P4. Each additional point is an LED bulb, increasing costs.
Different application scenarios
P3 screens are typically used indoors in large lecture halls, banquet halls, and similar settings due to their high clarity and contrast. On the other hand, P4 screens are suitable for performance stages, rental setups, and other scenarios requiring longer viewing distances. Outdoor P4 screens are common in squares and stadiums.
Conclusion
Both P3 and P4 displays offer unique advantages based on customer requirements. P3, with its smaller pixel pitch, provides superior visuals for close-up viewing, but at a higher cost. P4, with larger pixel spacing, is more cost-effective for longer viewing distances without a compromise in effectiveness.
