Comparing P3 P4 and P5 LED Displays A Buyers Guide

In an era of information overload, LED full-color displays have become indispensable tools for advertising, information dissemination, and stage performances due to their high brightness, vibrant colors, and long lifespan. However, consumers often find themselves perplexed by the array of models available—P3, P4, P5—and wonder what these alphanumeric combinations signify and how they differ. This article delves into the technical specifications, applications, and selection criteria for P3, P4, and P5 LED displays to help you make an informed decision.

To grasp the differences between P3, P4, and P5 LED displays, it is essential to understand two fundamental parameters: pixel pitch and resolution.

• Pixel Pitch: This refers to the distance between adjacent pixels on an LED display, measured in millimeters (mm). For instance, P3 denotes a pixel pitch of 3mm, P4 indicates 4mm, and P5 signifies 5mm. A smaller pixel pitch means more pixels per unit area, resulting in finer detail and higher image clarity.
• Resolution: This represents the total number of pixels on the display, typically expressed as horizontal pixels × vertical pixels (e.g., 1920×1080). Higher resolutions yield sharper images with richer detail.

Pixel pitch and resolution are intrinsically linked. For displays of the same size, a smaller pixel pitch translates to higher resolution and superior visual quality.

P3 and P4 LED displays, with their moderate pixel pitches, are often mounted as fixed LED walls for advertising or informational purposes. At a viewing distance of approximately 4 meters, the visual difference between the two is negligible, prompting many to question which is superior.

The distinction lies in the module types. A P3 LED wall uses P3 modules with a pixel density of 111,111 dots per square meter, while a P4 wall employs P4 modules with 62,500 dots per square meter. Higher density equates to sharper images, making P3 the better choice for close-range viewing—though at a higher cost. Both P3 and P4 displays can achieve 2K and 4K resolutions, depending on the desired outcome.

• Pixel Density: P3 offers 111,111 dots/m²; P4 provides 62,500 dots/m².
• Viewing Distance: P3 is ideal for distances over 3 meters; P4 performs best beyond 4 meters.
• Applications: P3 suits high-demand indoor settings like conference rooms and studios; P4 works well in semi-outdoor spaces such as malls and lobbies.
• Cost: P3’s advanced technology commands a premium over P4.

P4 and P5 LED displays are mid-range options widely used in various settings. Their differences are summarized below:

• Pixel Composition: Each pixel comprises red, green, and blue LEDs. P4’s 1mm smaller pitch allows for 20,000+ additional pixels per square meter, marking a significant technological advancement.
• Brightness and Power: P5’s lower pixel density grants it higher brightness, making it suitable for semi-outdoor or well-lit indoor areas. P4 consumes more power due to its higher pixel count and brightness exceeding 2200 cd/m².
• Viewing Distance: P5’s larger pitch makes it preferable for longer outdoor viewing distances.

When selecting an LED display, consider factors such as viewing distance, ambient lighting, and budget to determine whether P3, P4, or P5 best meets your needs.
