P3.91 LED Modules: Specs, Applications & Benefits of 3.91mm Pitch LED Displays

Introduction to P3.91 LED Modules

LED display technology has advanced tremendously in recent years. One of the most popular LED module form factors today is the P3.91 module. P3.91 refers to the dimensions - 3.91mm pitch between each LED. These p3.91 led modules offer high brightness, wide viewing angles, and seamless interconnectivity to build stunning outdoor led display walls and screens.

Benefits of P3.91 LED Modules

P3.91 LED modules provide several key advantages that make them ideal for outdoor led billboards, media façades, sports screens, and other large format outdoor led advertising displays:

• High brightness - P3.91 LEDs emit over 10,000 nits, ensuring excellent visibility even in direct sunlight
• Wide 160°+ viewing angle - Content looks good from any angle with minimal color shift
• Seamless interconnectivity - Modules tile together nearly seamlessly with 3.91mm pixel pitch
• Outdoor rating - Special protective casing and IP rating allows outdoor operation
• Flexible configurations - Tiles can be bent and curved, enabling flexible outdoor led screen shapes

P3.91 LED Architectures

P3.91 LED modules utilize advanced architectures and components to enable high visual performance:
