About Us

Shenzhen Grand Optoelectronics Co.,Ltd.

SHENZHEN GRAND-LED, a wholly-owned subsidiary of SHENZHEN GRAND INDUSTRIAL CO., LTD., has been a dedicated leader in the LED display industry for 16 years, with a strong focus on global exports. Our reach spans key markets including Europe, the United States, Australia, the Middle East, South America, and Asia, where we’ve built a reputation for reliability and innovation.

Backed by over 200 skilled employees—from engineers and technicians to production specialists—we operate out of a state-of-the-art manufacturing campus spanning more than 20,000 square meters. This expansive facility is the backbone of our production capabilities, housing advanced automated lines that streamline every stage of manufacturing, from PCB assembly and module integration to final testing. Equipped with precision machinery and robotics, our production lines ensure consistent quality at scale, with a monthly capacity to fulfill large-volume orders efficiently while maintaining strict adherence to international standards such as CE, RoHS, FCC and ETL.

Our commitment to excellence extends to rigorous quality control: dedicated labs within the facility are outfitted with cutting-edge testing equipment, including environmental chambers for extreme weather simulation, photometric analyzers for brightness and color calibration, and vibration testers for durability checks. This ensures every product—whether outdoor displays built to withstand harsh elements, rental displays designed for quick setup and portability, or indoor fine-pitch solutions (COB and GOB) delivering ultra-high definition—meets the highest performance benchmarks.

On the R&D front, we boast a 30-strong team of engineers and technical experts with deep expertise in LED optics, thermal management, and smart control systems. Over the years, this team has filed more than 50 patents, driving innovations like our proprietary COB and GOB technologies, which enhance display durability, reduce glare, and improve color accuracy. We prioritize collaborative R&D, working closely with clients to develop customized solutions tailored to their unique needs—whether for large-scale outdoor advertising, high-end event rentals, or indoor command centers requiring seamless visuals.

By combining large-scale production capabilities, stringent quality assurance, and forward-thinking R&D, GRAND-LED continues to be a trusted partner for global clients seeking reliable, high-performance LED display solutions.
