Requirements for sports LED display

• High refresh rate to ensure flicker-free images for live broadcast
• Synchronous signals to keep complete pictures on the display with no signal delay
• Easy installation to facilitate the service of dismantling and maintenance
• Impact resistance to protect the display from damage and players from injury
• Adjustable inclination angle to meet the best viewing angle and camera shooting angle
• Uniform and stable pictures to deliver perfect images for the audience

Technical solution for sports LED display

1. High-quality Components

• LED lamps: High-brightness and antistatic LED lamps with wide viewing range and antistatic ability of 2000V.
• Driving IC: Constant current LED driving ICs with current gain control; the light decay can be controlled to maintain a stable brightness.
• Connectors: Aircraft-grade reliable connectors, ensuring stable power supply and data transmission.
• Video processor: Professional video professor for center hung display, supporting various video signals such as AV, S-Video, RGB, YPBPR, VGA, DVI, HDMI, SDI, etc.

2. Advanced Control Technology

• High refresh rate: Refresh rate up to 3600 Hz, guaranteeing flicker-free pictures on the screen.
• High brightness: More than 7000nits, promoting vision effect.
• Real-time broadcast: High refresh rate, high brightness and wide viewing angle delivering high quality images for broadcast via professional video processor or video server.
• Calibration: Adopting Pixel-by-pixel brightness and color calibration technique to keep uniform brightness and natural colors of LED display.
• Double backup system: When one control system falls into malfunction, the other one will back up and start work immediately.
• Management software: Using special software to provide best advertising management solution for customers.

3. Effective Solution

• Easy installation and maintenance: Lightweight aluminum cabinets, easy to transport; interlock connection between cabinets, convenient to assemble and disassemble; easy to maintain the module and power supply box on-site without shutting down the whole system.
• Impact resistance: The soft mask of the cabinets absorbs the impact from balls or players. The top protective hat on the cabinet uses soft material to protect the players from injury and the cabinet itself.
• Adjustable inclination angle: The supporting stand behind the cabinets can be adjusted to adapt to different inclination angles (75°～ 90°) and camera shooting angles.
• Synchronous signals: Using optical fiber for data transmission without signal delay, ensuring synchronous displaying pictures.
• Energy saving: Adopting the techniques of LED lamps with low driving current, adjustable brightness, efficient power supply with PFC, less heat dissipation, appropriate power distribution from control system.
• Protection: IP65 standard cabinets (fully water proof) for outdoor and semi-outdoor use.
