| 1. Intended Use and Location | Indoor sports venues, arenas, event halls, studios, retail spaces, or other controlled-light environments. | An indoor perimeter LED display is a modular, narrow-format LED screen installed around the boundary of a playing or viewing area to show advertisements, scores, messages, and graphics. | Confirm the mounting position, available wall or floor space, audience sightlines, and local installation requirements. |
| 2. Pixel Pitch | Approximately 2.5–6 mm for most indoor viewing conditions; use a smaller pitch when viewers are closer. | Pixel pitch affects image detail and the minimum comfortable viewing distance. Smaller pitch generally provides finer image quality but can increase cost. | Measure the nearest audience distance. A commonly used estimate is minimum viewing distance in metres ≈ pixel pitch in millimetres. |
| 3. Brightness and Light Control | Typically about 800–1,500 nits for indoor applications, with adjustable brightness and automatic dimming preferred. | Excessive brightness can cause glare, while insufficient brightness can reduce visibility under strong venue lighting. | Check the venue’s ambient light levels and verify that brightness can be adjusted for daytime, evening, and broadcast conditions. |
| 4. Refresh Rate and Image Performance | At least 1,920 Hz for general indoor content; 3,840 Hz or higher is preferable for fast motion and camera-based production. | A higher refresh rate helps reduce flicker, scan lines, and visible artifacts when displaying moving content or recording with cameras. | Request camera test footage or conduct an on-site test using the same cameras and shutter settings used by the venue. |
| 5. Viewing Angle and Cabinet Design | Prefer a wide horizontal and vertical viewing angle, commonly around 140° or more, with lightweight cabinets and flexible installation options. | Perimeter displays are viewed from multiple angles. A wide viewing angle helps maintain color and brightness consistency around the venue. | Inspect the screen from the centerline, corners, and elevated seating areas before finalizing the layout. |
| 6. Protection and Safety Features | Use impact-resistant protection, padded edges, stable supports, flame-retardant materials, and suitable electrical safety protection. | Sports and event environments may expose the display to accidental contact, vibration, cable movement, and frequent installation changes. | Check protective masks, edge padding, locking systems, grounding, cable management, and compliance documentation. |
| 7. Maintenance, Reliability, and Operating Cost | Choose front- or rear-service access as required, modular replacement, efficient power supplies, monitoring functions, and a stated LED lifetime commonly around 80,000–100,000 hours under specified conditions. | Easy maintenance reduces downtime and labor costs. Actual lifetime depends on brightness, temperature, operating hours, and installation quality. | Review spare-part availability, service access, power consumption, warranty terms, monitoring software, and preventive-maintenance procedures. |
