Frequently Asked Questions
Q
What is the difference between P2.5, P3, and P3.91 LED displays?
The pixel pitch — P2.5, P3, and P3.91 — refers to the distance in millimeters between the centers of two adjacent LED pixels. A smaller pixel pitch (e.g., P2.5) delivers higher resolution and is better suited for close viewing distances, while P3.91 is more cost-effective for larger outdoor installations where viewers are farther away.
Q
Can these LED display modules be used both indoors and outdoors?
Yes. The P2.5 and P3 models are available in both Outdoor and Indoor variants with different module thicknesses and brightness levels to suit their respective environments. The P3.91 model is designed specifically for outdoor use, offering 4000 cd/㎡ brightness for high visibility in sunlight.
Q
What brightness level is recommended for outdoor LED displays?
For outdoor environments, a brightness of at least 4000 cd/㎡ is generally recommended to ensure clear visibility in direct sunlight. Both the P2.5 outdoor and P3.91 outdoor modules offer 4000–4500 cd/㎡, making them ideal for outdoor advertising and public display applications.
Q
What does the drive type (e.g., 1/16 or 1/32) mean for LED displays?
The drive type refers to the scan ratio of the LED module. A 1/32 scan means only 1 out of every 32 rows is lit at one time, cycling rapidly to create the illusion of a full image. A 1/16 scan lights every other row, typically producing higher brightness. The scan ratio affects both the brightness and refresh rate of the display.
Q
How is the dot density of an LED display calculated?
Dot density (pixels per square meter) is calculated as 1,000,000 divided by the square of the pixel pitch in millimeters. For example, the P2.5 display has approximately 160,000 dots/㎡ (1,000,000 ÷ 2.5²), while the P3.91 display has approximately 65,536 dots/㎡. Higher dot density means sharper, more detailed images.
Q
What cabinet sizes are available for these LED display models?
Cabinet sizes vary by model: the P2.5 supports 320×320 mm and 480×480 mm cabinets; the P3 supports 383×384 mm and 576×576 mm cabinets; and the P3.91 uses a 500×500 mm cabinet. These modular cabinet sizes allow flexible configuration for different screen dimensions and installation requirements.
