Typical Issues With LCD Screens On Naval Vessels

In the process of building an LCD system, it is important to take into consideration all environmental conditions that are associated with the application. When protection is included into the system in this manner, it is able to prevent expensive electronic repairs.Before beginning the construction of a maritime LCD system, it is important to take into consideration the following environmental considerations.

1. Strong Ambient/Outdoor Light

When viewing a digital screen outside, prolonged exposure to direct sunlight can soon cause reading issues that are incredibly uncomfortable.Sunlight has the ability to momentarily generate glare or almost completely wipe the image that is displayed on the screen.From a technical standpoint, the internal liquid crystal may eventually experience irreparable damage as a result of the ultraviolet (UV) rays that are emitted by direct sunlight. This damage may include color shifting and permanent wash out.In order to help fix these concerns, matte or anti-reflective surface polarizers, in conjunction with an LCD that has a strong LED backlighting system, can be of great assistance. Reading that takes place outside is enhanced by the incredibly bright LEDs, which are able to outshine the ambient brightness of the surrounding environment.In order to improve the readability of liquid crystal displays (LCDs) for users, anti-glare polarizer films are either built into the LCDs themselves or placed on top of them before they are used.Other highly effective integrations, such as an optical bond, alter the path that light takes through the liquid crystal display (LCD). This results in the screen being less reflective overall and improves readability by lowering the amount of reflecting patches that are contained within the LCD.

2. Extremely High Or Low Temps

Extreme temperatures, whether they be caused by the sun, the outdoors, or other environmental conditions, can hasten the deterioration of components under certain circumstances."Heat can disrupt this by randomizing what is meant to be controlled," OrientDisplay.com points out, "because liquid crystals are manipulated in a device by altering their orientations and alignments" (Source).This can result in a variety of display flaws, such as color failures, dark areas, light spots, full black or white displays, and finally liquid crystal degeneration. High temperatures can cause the liquid crystal to behave in an unpredictable manner, which can lead to these display faults. The failure of electrical components such as controllers and the melting or deformation of components such as adhesives, gaskets, and films can occur under severe conditions.It is possible that the LCD will operate slowly (slow response time), that it will take several seconds to refresh an image, and that it will display colors that are not accurate if the temperature is too low.Even though it is still a hazard, the likelihood of a display being irreparably destroyed by cold temperatures is much reduced.It is feasible to find a solution to these problems by selecting the screens that have the greatest temperature range potential.In the event that it is necessary for your design or application, your designs may also integrate solutions to deal with extremes of temperature, such as blowers, heaters, and heater-glass.

3. Wetness


All metal equipment and electrical components are subject to quick deterioration and corrosion when exposed to water, and salt water in particular is extremely hazardous. Protecting cables, screens, and other components that come into touch with water against water infiltration is essential for preventing malfunctions and ensuring data integrity. Any metal display chassis or frame must have sufficient insulation in order to prevent rust and corrosion from becoming a problem.

The display should be kept out of the wet environment whenever it is possible to do so, or a suitable wind or spray screen should be utilized in order to avoid it from being exposed to mist or water.Gaskets, optical bonding, and components with an IP rating should all be incorporated into your design. Also, make sure that the display is cleaned and maintained on a consistent basis through regular maintenance.It is possible to adjust the touch screen so that it can be used by wet fingers.This page contains further information regarding our services for integrating touchscreens.

4. Other Pollutants And Dust

Erroneous readings from the user might be caused by dust and other contaminants that are present both within and outside of the display. Dust that has accumulated inside the display has the potential to cause it to overheat, which could then result in a short circuit.In the event that dust is not frequently cleaned and removed from a touch display, it has the potential to reduce the accuracy of the touch sensors on the display. In the event that the liquid crystal display (LCD) is damaged and leaking liquid crystal, on the other hand, potentially hazardous chemicals from the display could leak out and be found in close proximity to the display as dry dust.In order to address this issue, you should carry out a thorough quality control inspection, incorporate gasketing that is rated for IP protection into your design, and undertake routine maintenance and cleaning regularly.

5. Vibration And Movement

During times of rough waves, the display will both vibrate and shift a great deal. The printed circuit board, often known as the PCB, is a typical LCD point of failure in situations that are subject to high levels of vibration. Among the components that are managed by the PCB are the LCD controller, the power management, and other components.A connector, fastener, or solder point will typically break and fail at this point because it is the point at which vibration causes it to happen.Gaskets and other rubber components that have been used for a long time or that have been degraded may develop defects, which could lead to failure.Your display can be strengthened by employing optical bonding, components that have been ruggedized, and casings made of plastic or metal.

6. Effect


There is a possibility that a blow to an LCD will cause the touch screen, the liquid crystal glass, or the outside cover to fracture or crack. Impacts can have potentially damaging effects, including the breaking of glass and the release of toxic compounds into the environment. There is a possibility that powerful impacts will entirely damage the display as well as all of the ancillary components that it contains.Together with glass that has been chemically strengthened, optical bonding that has been toughened might be utilized to make your display more resistant to the kinds of shocks that are being described. You can choose from a wide range of substrate types, each of which has a unique set of tough features that are tailored to meet the specific requirements of your application.For additional information regarding our unique glass integrations, please click here.

If your display is equipped with premium strong components and modifications, it will most likely be able to withstand vibration and other forms of movement.In the event that it is subjected to normal maintenance, your robust marine system has the potential to outlive its expected lifespan and continue to operate faultlessly throughout the entirety of your boat.
