Wall-mounted LED screens are versatile display solutions for both indoor and outdoor environments, combining space efficiency with high-performance imaging. Indoor models typically feature fine pitches (P1.2-P3) for boardrooms and control rooms, utilizing slim cabinets (≤50mm depth) for flush mounting. Outdoor wall screens (P4-P12) incorporate weatherproof designs, with aluminum frames and sealed modules to withstand rain and dust. Mounting systems include fixed brackets, tilting arms, or full-motion pivots to achieve optimal viewing angles. In retail settings, they serve as digital shelves to display product information; in healthcare, they function as patient education displays. Some models support dual-sided display for transparent installations, while others integrate NFC or QR code readers for interactive experiences.
