Illustrate

Liquid crystal displays (LCDs) play a crucial role in modern marine equipment, with applications spanning a wide range of vessels (such as merchant ships, cruise ships, and sailboats), jet skis, speedboats, and recreational equipment like surfboards. Within these devices, LCDs are primarily used for key functions such as navigation systems, instrument displays, radar and sonar interfaces, engine monitoring, and entertainment information interaction. They provide operators with real-time, clear data support, enhancing navigation safety, operational convenience, and user experience.

Application Notes

1. Electronic Chart Display and Information System (ECDIS):

The "brain" and "digital map" of ship navigation. The ECDIS display integrates the data of vector electronic charts with GPS positioning, gyrocompass, speed log and other navigation equipment to display the data in real time and accurately.

2. Comprehensive navigation information display

It is usually superimposed on the ECDIS or radar display in the form of a digital instrument panel or data bar, displaying key real-time dynamic parameters.

3. Radar/ARPA image overlay display

The display screen renders the echo images of the surrounding water and air objects detected by the radar antenna in real time. Modern radars are usually integrated with automatic radar plotting aids (ARPA).

4. Ship power and control system monitoring

Dedicated display screens (usually touch screens) obtain data from the engine room centralized control system (ECS) and ship automation system, and display them in the form of schematic diagrams, instruments, graphs and lists.

5. Comprehensive weather information display 

The display integrates global weather data from onboard weather sensors (wind speed and direction, barometer, etc.) and satellite communications, including real-time local weather, weather forecasts, and warnings.

6. Comprehensive weather information display

All of the above systems are connected to a central alarm management system. The displays centrally manage and announce all security-related alarms visually (flashing, color changes, pop-up windows) and acoustically (buzzer).

Display screens have become the indispensable "eyes" and "brains" of modern navigation, and are core technical equipment for ensuring safe, efficient and environmentally friendly maritime navigation.

Parameter requirements for navigation equipment

The display screens of marine equipment must meet stringent environmental and operational requirements in terms of parameters to ensure stability and reliability in the special marine environment.

First, high brightness is a fundamental requirement, typically exceeding 1000 nits, with some applications requiring 1500 nits or higher to ensure legibility even in direct sunlight.

At the same time, the display must exhibit excellent anti-glare and anti-reflection properties, often using optical bonding or surface treatments to reduce specular reflections and light interference.

In terms of environmental adaptability, the screen must support a wide operating temperature range, from -30°C to 80°C, and withstand long-term operation in high humidity and salt spray conditions. The enclosure must generally meet IP66 or IP67 protection levels to effectively prevent seawater intrusion and salt spray corrosion.

In terms of mechanical properties,The module must pass vibration and shock tests to ensure normal display under continuous ship shaking or high-speed impact environments.

In addition, if the touch function is integrated, it must support operation with wet hands and gloves, adopt a highly sensitive and anti-interference projected capacitance solution, and have good electromagnetic compatibility (EMC) to avoid interference with other electronic equipment on board.

In terms of display characteristics, high contrast (e.g., over 1000:1), wide viewing angles (up to 178° vertically and horizontally), and reliable backlight life are also essential parameters. Marine displays are designed to comply with maritime standards in terms of optical, structural, environmental, and electrical performance to meet the stringent safety, durability, and real-time requirements of marine applications.
