MAXTOP has completed a landmark sports-venue installation at Dongguan Basketball Center: a high-impact center-hung LED display configured as a four-sided indoor P3.91 screen. Each face measures (8 m flat + 0.25 m curved corner) × 5 m, multiplied by four sides, forming an uninterrupted wrap-around visual canvas. Unlike a conventional cube scoreboard, this solution integrates our AC-RG Pro series 90° arc corner cabinets with our AC-50 rental series to eliminate visual breaks at the corners and maintain smooth content motion across edges. The result is a camera-ready, audience-friendly center-hung LED display that elevates replays, stats, and sponsor content.

Why Curved Corners Matter in a Center-Hung LED Display

Traditional center-hung LED displays rely on sharp 90° joins that cause aliasing, content tearing, and brightness falloff at the seams. By adopting an arc-at-the-corner architecture, we create a continuous transition zone where pixels are oriented to keep lines, graphics, and text flowing. Benefits include:

  • Seamless motion: Video pans and score animations stay coherent through corner transitions.
  • Wider viewing cone: Curved edges extend visibility to spectators seated off-axis.
  • Reduced moiré and reflections: The gentle radius minimizes corner glare under arena lighting.
  • Premium aesthetics: A monolithic, wrapped display surface enhances brand and event perception.

System Composition and Key Specifications

AC-RG Pro 90° Arc Corner Cabinets

  • Indoor pixel pitches: 1.5/1.9/2.6/2.9/3.91 mm
  • Outdoor pixel pitches: 2.9/3.91 mm
  • Small 90° arc corner design with independent control box
  • Seamless, high flatness; magnetic front maintenance; quick-lock splicing
  • Dimensions: 500 × 228 × 108 mm

AC-50 Series LED Rental Cabinets

  • Panel size: 500 × 500 × 84 mm
  • Indoor pitches: 1.5/1.9/2.6/2.9/3.91 mm; Outdoor: 2.9/3.91 mm
  • Four form factors: Flat, Curve, Right angle, Cube
  • Thermal design, precision die-casting, durability, quick installation
  • Magnetic front maintenance for rapid service

Together, these modules produce a uniform center-hung LED display surface with minimal seam visibility and superior flatness across the entire 360° perimeter.

Engineering Challenges and How We Solved Them

Corner Geometry and Pixel Alignment: The 0.25 m curved transition demanded sub-millimeter tolerance to prevent visible discontinuities. We pre-modeled the corner radius and used AC-RG Pro’s quick-lock and magnetic alignment to lock pixel rows across the arc. Result: corner seams below perceptual threshold at typical viewing distances.

Structural Load and Thermal Balance: A four-sided structure with mixed cabinet types requires balanced mass and heat dissipation. AC-50’s thermal design and the AC-RG Pro’s independent control boxes enabled distributed airflow paths. We validated with thermal imaging during a full-brightness burn-in.

Signal Uniformity and Synchronization: To avoid latency drift across faces, we standardized cabinet mapping and daisy-chained synchronized receiving cards. The independent corner control boxes simplified loop routing while safeguarding redundancy, ensuring the center-hung LED display stays fully synchronized for replays and live data.

Maintenance Access at Height: Arena rigs demand fast service. Magnetic front maintenance on both AC-RG Pro and AC-50 lets technicians replace modules from the catwalk side without dismantling corners, minimizing downtime.

On-Site Result and User Impact

The curved-corner geometry removes the visual “breaks” typical of cube scoreboards. Graphics glide around the screen without tearing, and sponsor creatives retain brand integrity across faces. Spectators benefit from consistent brightness and color even when seated diagonally to a corner. Operations teams report faster content programming due to predictable corner behavior and fewer masking workarounds.
