Guangzhou Chaowei Technology Development Co., Ltd.

China, the supplier lists 8 active products across electronic display boards and LED components. Guangzhou Chaowei Technology Development Co., Ltd. offers a catalogue that includes four outdoor full‑color LED screens (P10, P12, P16, P20) and three indoor displays (P7.62, p4.76 double‑color, P20). Two of the outdoor models are classified under HS code 8528.59 for electronic display units with aluminum/steel frames, while the semi‑outdoor red module and the P16 screen fall under HS code 8531.20 covering LED semiconductor components with PCB and aluminum housing. The remaining items are listed without specific HS codes in the source data. All products are described using pixel‑pitch designations (e.g., P20 indicates a 20 mm pitch) and are described as full‑color or single‑color LED modules. The catalogue groups the items under the broader categories of Electronic Display Board and Light Emitting Diode components. The outdoor displays are positioned for high‑brightness, weather‑resistant installations, whereas indoor units target close‑viewing environments with finer pixel pitches. The supplier’s product count of eight reflects the range of module sizes and color capabilities, from double‑color indoor panels to single‑red semi‑outdoor modules. No additional product specifications such as power consumption or warranty terms are provided in the source data.

The listed outdoor full‑color LED displays (P10, P12, P16, P20) cover pixel pitches from 10 mm to 20 mm, which in the LED signage industry correspond to viewing distances of 5 - 15 m and brightness levels of 5,000 - 8,000 nits to ensure visibility in direct sunlight. Indoor models such as the P7.62 and p4.76 panels use finer pitches of 7.62 mm and 4.76 mm, typically delivering 3,000 - 4,500 nits suitable for shopping malls or conference rooms. Common material constructions include aluminum extrusion frames, steel reinforcement for outdoor rigs, and PCB‑mounted semiconductor chips, matching the material descriptions in the supplier data. Industry standards for LED display modules often require compliance with IEC 62471 for photobiological safety, IEC 60870 for electromagnetic compatibility, and RoHS restrictions on hazardous substances. Buyers frequently look for CE or UL certification to satisfy European and North American market requirements. Typical grades include IP65 or higher for outdoor enclosures and IP54 for indoor units, ensuring protection against dust and water ingress.
