Waterproofing

The most obvious factor in the marine environment is the presence of water. When electronic equipment is used in a boat, there is always the chance of water being splashed onto it. This is especially likely to happen in heavy seas, even if the equipment is installed indoors.

Corrosion

The salty ocean is always evaporating and splashing into the air, which produces salty water vapors in the air. Metals tend to corrode (e.g. iron and steel go rusty) very quickly in the presence of salty water or salt vapors, as it accelerates the oxidation process. Hence the marine environment presents a challenge for equipment made from various metals.

Shock And Vibration

For successful long term usage on marine platforms such as ships and boats, Marine LCD Display Screen need to tolerate a high level of shock and vibration. On a large ship platform, it might seem like the ship is very smooth, but in reality there is often a humming and vibration coming from the engines, gear boxes, propellors etc. In addition, ships and smaller boats must be able to handle the roughest of sea states, which can literally throw a vessel around with huge amounts of force.

Wide Temperature

As marine vessels can be taken anywhere in the world, they must be rugged enough to cope with the coldest and hottest of environments. Hence for indoor marine monitors they should be rated for at least 0 to 50 degrees C. Outdoor marine monitors need an even wider temperature range if they are to operate in all weather conditions.

Brightness And Dimming

Typically Marine LCD Display Screen are used in places where there are also windows (or periscopes for submarines), hence the light levels will vary from the brightest sunlight down to the darkest night. In bright sunlight, regular Marine LCD Display Screen become unreadable, so it is important for marine LCD’s to use technologies to make the screen readable in direct sunlight.

Optical Bonding

Optical Bonding is defined as “The affixing of two rigid optical elements using transparent adhesive to reduce reflectance and provide additional protection”.

Power Connections

In marine environments, the available power sources may be either low voltage DC (24V typically), or else AC mains voltage (110V or 230V AC). Where it is a small vessel with a DC power supply, the voltage can be subject to fluctuations caused by the starting / stopping of engines, battery charging / discharging etc. Hence DC powered Marine LCD Display Screen must be tolerant of a wide range of voltages.
