LED Technology Essentials

LED displays function by combining red, green, and blue (RGB) LEDs within each pixel to produce a wide color gamut. In LED poster screens, surface-mount device (SMD) LEDs are most commonly used due to their compactness and ability to produce uniform light distribution. Advances in LED semiconductor materials, often based on gallium nitride (GaN), have significantly improved the luminous efficacy and lifespan of LEDs, enabling bright, long-lasting displays.

Sunlight-readable LED poster screens typically offer peak brightness levels ranging from 3,000 to over 7,000 nits, significantly surpassing the typical LCD panels (around 300 to 700 nits). This high brightness ensures excellent legibility in direct sunlight, a crucial factor in outdoor or semi-outdoor environments.

Pixel Pitch and Resolution

The pixel pitch, defined as the distance between the centers of adjacent LED pixels, is a critical technical parameter influencing image clarity and viewing distance. Common pixel pitch values for LED poster screens range from 1.2 mm to 2.5 mm for indoor contexts, and up to 4 mm or more for outdoor usage. Reduced pixel pitch yields higher resolution and finer image detail, suitable for close-proximity viewing, whereas larger pitches optimize cost and visibility in larger-scale or longer-distance scenarios.

Display Size and Form Factor

LED poster screens are designed with versatility in mind, often ranging in size from approximately 32 to 65 inches or larger, allowing them to replace traditional paper posters or LCD screens in advertising kiosks, retail windows, transportation hubs, and corporate spaces.
