From our R&D center in Wuhan Optics Valley to landmark screens on every continent — a total LED solution provider with direct-source manufacturing.
HLD has 10 years of LED display expertise and 3,000+ projects worldwide. We specialize in outdoor fine-pitch, COB and other LED display solutions, offering OEM / ODM, system integration, custom design, drawings and technical support.
Three things we hold on to — shown with our own lab, our own factory floor and our own people.
01 · Technology — the bone
Our R&D team in Wuhan Optics Valley designs the InkScape™ COB platform, the cabinets and the control together — and measures every series in our own optical lab before it reaches a customer.
02 · Supply chain — the wing
Because we run the lines ourselves, we can quote directly, customise structure and software for your project, and ship without a middleman — OEM to your design or ODM from ours.
03 · Culture — the soul
知行合一 — the unity of knowledge and action. We keep a promise the way we build a screen: carefully, and all the way. The same team that climbs mountains together also builds classrooms for rural schools.
Wuhan Optics Valley is China’s national optoelectronics hub. Our R&D sits inside it; our factory is a short drive east in Ezhou — close to talent, labs and the LED upstream cluster.
