Sirius IC Driver
Frequency-Tunable Multi-Mode IC Driver
Sirius is a frequency-tunable Multi-Mode IC driver, custom-designed exclusively for ROE Visual LED panels and integrated with Deepsky processor as a unified ecosystem.
With 22-bit native grayscale, a freely tunable base frequency up to 15,360 Hz, and <1 JND thermal color stability, Sirius eliminates common on-camera issues such as scanlines and color shifts across shutter angles and frame rates.
Designed for filmmakers, broadcasters, and reference monitor applications, Sirius delivers accurate color, deep blacks, and consistent on-camera performance.
22-bit Native Grayscale
Sirius delivers 22-bit native grayscale with no visible dithering, producing smoother gradients, deeper blacks, and finer shadow detail—even in low-brightness scenes.
12-bit PWM + 11-bit PAM
Sirius combines PWM time-domain control with PAM current-amplitude control to achieve high-depth grayscale and smooth tonal transitions across the full brightness range.
15,360 Hz Tunable Base, Continuous Scanning
Sirius continuously scans at a tunable base frequency up to 15,360 Hz, precisely adapting to different frame rates and shutter angles. For example, at 60 fps and a 172.8° shutter angle, the panel can synchronize directly with the camera, eliminating scanlines and flicker for clean, stable images across on-set and broadcast applications.
Per-IC Thermal Sensing for <1 JND Color Drift
With dual temperature sensors on every driver IC, Sirius creates a real-time thermal map for dynamic, region-specific compensation. Color error stays below 1 JND, maintaining consistent color accuracy even during extended operation.
On-Chip RISC-V Intelligent Control Core
Sirius integrates an on-chip RISC-V MCU for autonomous scan timing, intelligent power saving, and anomaly recovery. It reduces controller workload while enabling pixel correction, blanking optimization, and open/short fault reporting.
Sirius Meets Ruby
Ruby is the first ROE Visual LED panel series powered by Sirius, combining the custom driver IC with advanced thermal management for optimized performance and consistent image quality.
