MGLS24064-47C LCD Module PCB-LS24064#1-01 Graphic Display Unit
The MGLS24064-47C (PCB reference PCB-LS24064#1-01) is a 240×64 dot-matrix monochrome STN transflective graphic liquid crystal display (LCD) module. Engineered for marine automation architectures, engine telegraph displays, main engine propulsion remote controls, power management systems (PMS), and bridge monitoring consoles, this unit delivers high-contrast optical readouts under direct sunlight and bridge night-vision conditions.
Driven by the industry-benchmark Toshiba T6963C (or functional equivalent) onboard controller with integrated display RAM, the module features an 8-bit parallel MPU interface, hardware/software font generation and independent dual-layer text and graphic rendering. The heavy-duty industrial PCB substrate meets UL 94V-0 flammability ratings and complies with marine classification society shock and vibration thresholds (IEC 60068-2-6 / IEC 60068-2-27), ensuring resilient uptime in demanding engine control room (ECR) and wheelhouse environments.
