Highlander HLD-DU134 Display & MCU: The Bridge Processing Core
The human-machine interface and digital processing backbone of Highlander bridge systems comprise the HLD-DU134 Marine Display Unit and the dedicated Main Control Unit (MCU / PCU), engineered to deliver continuous 24/7 conning presentation in extreme bridge temperature ranges (-15°C to +55°C).
Optical Bonding & Anti-Reflective Display Characteristics
- Resolution & Aspect Ratio: Available in 19-inch (1280×1024), 24-inch (1920×1200 wide), and 27-inch (1920×1080) high-definition formats compliant with IMO display radius rules.
- Full Optical Bonding: The LCD panel is bonded directly to the protective front glass using optical silicone gel, preventing condensation fogging during tropical humidity shifts and eliminating internal double-surface light reflections.
- Zero-Black Dimming: Equipped with PWM backlighting control allowing continuous dimming down to < 0.5 cd/m² for night bridge watch preservation.
MCU Signal Processing & Sensor Multiplexing
The MCU processor cabinet houses the high-speed Analog-to-Digital Converter (ADC) board that samples raw radar video at 100 MHz, the digital signal processor (DSP) executing real-time CFAR clutter filtering, and isolated RS-422 serial interface ports accepting heading, navtex-system-service-and-repair/” class=”seanav-internal-link”>speed log, and GNSS sentences.
