Product Highlights
Optional Size
Standard size supports 640×480. Multi-size options include 320x160mm, 320x480mm, 320×160, 320×480, 640x640mm and 960x480mm. Vertical and horizontal arrangements can match any required screen size. Die-casting aluminum with precision tolerance below ±0.2mm supports seamless, perfect splicing.
GOB & COB
GOB (Glue On Board) adds glue to the surface of SMD, while COB (Chip On Board) uses LED chips directly without encapsulation. Both make the screen surface waterproof, anti-hit, anti-static and strong. COB offers better performance, higher contrast ratio, wider viewing angle and more vivid colors. The cabinet is 61mm thick and weighs 7.8kg at 640x480mm.
Front Maintenance Service
Users can replace the module, power supply or receiving card individually from the front. P1.8 and P2.5mm offer an optional 4000nits high-brightness version designed for window screens facing sunlight, keeping images vivid and clear.
Movable BMposter
Standard sizes are 640×1920 and 960x1920mm. Several units can cascade seamlessly, with plug-and-play phone control. Customized curved and 90 degree designs can be made smoothly using a special connection plate.
Safetly Hanging
A light cabinet can be safely hung with a hanging bar to save space. For permanent wall installation, aluminum mounting brackets fix the cabinets and improve flatness.
