High-end marketing brochure rendering of a modern concave LED video wall using LP Display ArcX Series COB panels (300 x 675 mm), overall size approximately 3.6 m wide and 2.0 m high, concave radius 5-6 m. The LED wall is only partially assembled: approximately 60% of LED panels mounted and 40% of the supporting structure exposed. Clearly visible engineering-grade substructure built from item24 aluminum extrusion profiles. Use only single 40 x 40 mm T-slot aluminum profiles with matching angle brackets, corner connectors, cross members, vertical supports, mounting interfaces and height-adjustable leveling feet. Focus on technical planning and engineering quality. The concave geometry must be clearly recognizable. Precise structural design, realistic assembly details, professional exhibition and AV engineering appearance. Wall is powered off, dark inactive COB LED surface, no content shown, no cables visible. Monochrome black-and-white industrial aesthetic, white seamless studio background. Product photography style with soft shadows. Perspective slightly from front-left, eye-level view. Emphasize modularity, stability, precision engineering and clean construction. Highly detailed, photorealistic, industrial design visualization, brochure-quality rendering, technical accuracy, clean composition, ultra sharp, premium lighting, no people, no text, no logos, no empty scene. xploded engineering presentation style, allowing visibility of both the LED modules and the structural Ver mais
