Key Features
- Six-port LED screen control: Drives up to 3.9 million pixels through six Ethernet output ports.
- HDMI 1.3 input and loop output: Integrates easily into professional video signal chains.
- 10G optical output: Supports fiber-based signal transmission for suitable LED display installations.
- Flexible scaling: Choose custom scaling or pixel-to-pixel output according to the source and screen resolution.
- Low-latency processing: Provides zero-frame controller latency of less than 1 ms without reducing the loading capacity.
- Adjustable frame delay: Adds 0 to 2 frames when system synchronization requires it.
- Frame-rate adaptation: Supports common and decimal input frame rates, plus fine adjustment in 0.01 Hz steps.
- Irregular screen mapping: Blank areas do not consume loading capacity; Ethernet load is calculated from the combined cabinet resolutions.
- System monitoring: Monitors controller and display status and reports fault or alarm information.
Precision Calibration and Image Quality
Full-Grayscale Calibration
When used with NovaStar’s high-precision calibration system and C3200 scientific-grade camera, the KU20 can apply correction coefficients across grayscale levels to improve grayscale uniformity and overall display quality.
Pixel-Level Brightness and Chromaticity Calibration
The controller supports point-by-point brightness and chromaticity correction. This helps reduce visible differences between LED pixels and improves brightness and color consistency across the screen.
Typical Applications
The NovaStar KU20 is suitable for professional LED display systems that require COEX control, precise calibration, low latency, or fiber output. Typical uses include rental LED screens, stage and event displays, control rooms, broadcast environments, and fixed LED video walls.
