LED ventilation curtain screens are innovative dual-functional display solutions that combine LED digital display with natural ventilation—addressing the conflict between large-scale outdoor displays and building airflow needs. Designed primarily for building exteriors, shopping mall facades, and semi-outdoor venues, these screens feature a unique porous structure that allows air to circulate freely while delivering high-quality visual content.

The ventilation functionality of these screens is achieved through a specialized grid design. Unlike solid LED displays that block airflow, LED ventilation curtain screens use a sparse matrix of LED modules with large open gaps (ventilation rate 40–70%). The modules are arranged in a staggered or grid pattern, creating channels for air to pass through—reducing indoor temperature buildup and lowering the need for air conditioning. For example, a shopping mall with a 15m×8m ventilation curtain screen on its facade can maintain natural airflow, keeping the interior cooler in summer and reducing energy consumption by 15–25% compared to a solid screen.

In terms of display performance, LED ventilation curtain screens match traditional outdoor LED screens. They use high-brightness SMD LEDs (2500–5000 nits) with pixel pitches ranging from 10mm to 40mm, ensuring clear visibility in direct sunlight. The screens support full-color video playback, text scrolling, and animation, with a refresh rate of 300–800Hz for smooth, flicker-free content. The modular design allows customization of screen size and shape—they can be installed as flat walls, curved surfaces, or even irregular shapes to fit unique building facades.

Durability is tailored to outdoor use. The LED modules are encapsulated in waterproof silicone (IP65 rating) to resist rain, dust, and corrosion, while the frame is made of lightweight, rust-proof aluminum alloy. The screens are also wind-resistant: the porous structure reduces wind load by 50–60% compared to solid screens, making them suitable for high-rise buildings or coastal areas prone to strong winds.

Common applications include shopping mall facades (where ventilation is critical for indoor comfort), semi-outdoor markets (displaying product promotions while maintaining airflow), and industrial building exteriors (showing safety information or production data). By integrating display and ventilation, these screens offer a practical, energy-efficient solution for outdoor spaces where both visual communication and airflow are essential.
