AOISUN Launches DS4 Warning Screen: Ultra-Lightweight Visual Alert System for DJI UAVs

[Nanjing,March12,2026] — AOISUN, a leading provider of specialized drone payloads for critical industries, today unveiled the DS4 Warning Screen, an advanced UAV-mounted visual alert system engineered to deliver long-range, high-visibility warnings for traffic control, public safety, and emergency response operations.

Designed for seamless integration with DJI drone platforms, the DS4 combines a 23.4-inch full-color display with an ultra-lightweight 4-fold hollow structure, setting a new standard for payload efficiency and visual performance.

• Lightweight 4-Fold Hollow Design: At just 240g, the DS4’s fully hollow structure minimizes UAV payload impact while delivering a large 23.4-inch display area, ensuring optimal flight performance and maximum visibility.
• Full-Color LED Visuals: Equipped with 1024 full-color LED beads (supporting red, green, blue, yellow, and white), the system offers a 120° wide light-emitting angle for extensive coverage across large operational areas.
• Long-Distance Visibility: Text warnings remain clearly visible up to 100 meters, while high-intensity flash patterns achieve 1000-meter visibility—ideal for early warning in traffic, maritime, and disaster scenarios.
• Flexible Control & Operation: Compatible with DJI PSDK, a dedicated mobile app, and WeChat Mini-Program, the DS4 supports remote parameter adjustment, text playback (page-turning/carousel modes), and multi-pattern flashing (single-color, dual-color alternating).
• Rugged Reliability: With an IP-rated build and operating temperature range of -10°C to 50°C, the DS4 delivers consistent performance in challenging outdoor environments, from urban traffic hubs to coastal disaster zones.
• Quick-Release Installation: The screw quick-release mounting system enables fast, tool-free deployment onto DJI UAVs, reducing pre-mission setup time for time-sensitive operations.

The DS4 Warning Screen addresses critical pain points across high-stakes industries:

• Traffic Control: Displays directional guides and flash alerts at accident/construction zones, with 1000m flash visibility for early vehicle warning.
• Public Safety: Issues crowd control prompts and warning messages during patrols, enhanced by dual-color flashing for on-site deterrence.
• Emergency Response: Projects evacuation routes, safe zone markers, and danger warnings at fire, flood, or earthquake disaster sites.
• Maritime Safety: Delivers ship navigation guides and emergency alerts with long-range visibility penetrating marine conditions.
• Event Management: Provides crowd guidance and safety information at concerts, sports events, and large public gatherings.

“Visual clarity and payload efficiency are non-negotiable in critical drone operations,” said the Chief Product Officer at AOISUN. “The DS4 Warning Screen redefines what’s possible: a large-format display that weighs just 240g, with 1000m flash visibility and full-color versatility. It transforms DJI UAVs into mobile command centers, enabling teams to communicate faster, warn earlier, and protect lives more effectively.”

The AOISUN DS4 Warning Screen is now available for global orders, with delivery within 2 weeks.
