Mesh LED
Blurring the Line Between Architecture and Digital
Ultra-Light, High-Transparency Mesh LED Display

 Mesh LED displays are high-transparency screens designed by placing LED light-emitting elements onto a lightweight, mesh-like structure that allows wind and light to pass through. Compared to conventional LED displays, they are significantly lighter and more transparent, making them ideal for large-scale installations on building exteriors, glass facades, and skyscrapers. Without compromising the architectural appearance, they enable the realization of large-format media facade.

Low Wind Load Design
Safe for High-Rise Installation
High-Transparency Design
30–70% Transparency Rate
Ultra-Lightweight Structure
50% Less Load Than Conventional LEDs
Large-Scale Media Façade
Scalable Structure for Expansion
Modular Design for Quick Maintenance

Illuminating Glass
A Breakthrough in Transparent Display Technology

Film LED is a transparent display technology characterized by its thin and flexible form, allowing easy attachment to glass surfaces or curved structures. With a high transparency rate of up to 90%, it does not block natural light, offering excellent energy efficiency and simple installation. This makes it ideal for commercial spaces and building facades where both aesthetics and performance matter.
