Shenzhen Haojingyuan Optoelectronic Co., Ltd.

Shenzhen, China hosts Shenzhen Haojingyuan Optoelectronic Co., Ltd., which currently lists 20 active products across its catalogue. The company’s listings fall under the Light Emitting Diode and Electronic Display Board categories, with additional entries related to Agriculture and Steel Structures. Product titles include outdoor Wi‑Fi digital message boards, full‑color LED modules, video‑wall panels and specialized indoor LED panels, many of which are identified with pixel‑pitch codes such as P16, P5 and P3.91. Several items carry HS codes 8528.49 for LED display panels and 8528.72 for other LED display units, indicating their classification under “Monitors and projectors, other than television receivers”. The material descriptions reference aluminum frames, steel mounting structures, PCB boards and RGB SMD LED components, reflecting typical construction of modern LED signage.

The catalogue also contains items without explicit HS codes, such as steel billboard structures and mobile food‑truck LED panels, which are still part of the broader LED display ecosystem. The presence of both indoor and outdoor models suggests a focus on versatile display solutions for varied lighting environments. The inclusion of “Paper Thin Hot Product LED Moving Signs” and “Digital LED Advertising Billboard” highlights capabilities in thin‑profile, high‑resolution signage. Overall, the supplier’s product set spans a range of pixel pitches, cabinet designs and mounting options, offering buyers a broad selection of LED display technologies.

Shenzhen Haojingyuan’s listed products cover a spectrum of LED display formats, from small‑format indoor panels (4.81 mm pitch) to large outdoor video‑wall modules (P16 pitch). In the LED display market, pixel pitch is a primary specification, with outdoor installations typically using 10 mm to 20 mm pitches for long‑distance viewing, while indoor venues often select 2 mm to 6 mm for close‑range clarity. Brightness levels for outdoor panels usually range from 5,000 to 8,000 nits, with an IP65 or higher ingress protection rating, whereas indoor units commonly target 1,200‑2,500 nits and an IP20 rating. Common LED chip types include SMD 2835, 3528 and the higher‑output 5050, mounted on PCBs with aluminum heat‑sinks to manage thermal performance. Standard cabinet constructions employ aluminum frames combined with steel reinforcement, matching the material notes in the catalogue. Buyers also encounter modular designs that allow panel stitching for scalable video walls, a feature reflected in the “Video Wall Outdoor” and “Stage Background” entries.
