INDUSTRIAL LCD MONITOR

LCD stands for Liquid Crystal Display. Liquid Crystal Displays that are used for industrial purpose are often rugged monitors that can withstand the wear and tear of the industrial use. Mostly, industrial lcd monitors will be used with industrial computers as a computer peripheral. Besides that industrial lcd monitors are also used as independent display units for displaying video images that are received from various sources such as surveillance cameras. These days LCD displays are preferred over CRT monitors because industrial lcd monitors occupy less space when compared to CRT monitors. Moreover, the power consumption of LCD monitors is much lower than the traditional CRT monitors which were once used for industrial purposes. By using an LCD monitor you can save from 80% to 90% of the space that would be used by a CRT monitor and at least 50% on the electricity bills. Moreover, LCD monitors cause less damage to the eyes even when we watch video images for long hours.

The only difference between the ordinary LCD monitor and the industrial lcd monitor is the external casing. The industrial lcd monitor comes with a rugged or tough casing for increased durability. They often come in steel or aluminum frame so that it can be fixed easily on an equipment rack.
It sounds like a myth when we hear that mariners calculated their position on the sea and their sailing course using stars. With the latest marine computer navigation system at our disposal, mariners are able to sail as confident as driving on our highways. Traditionally, mariners would have had very limited information and every journey would have been a matter of life and death. It is not the case anymore; we can mark with precision our exact location without having to plot endless charts that we used in the past. Computer navigation system saves us a lot of time and energy; above all they are very accurate.
Today marine GPS or global positioning system provides the mariners with all the information that they need with just a few clicks. Today no marine vessel leaves the dock without computer navigation system. They have become one of the essential accessories of sailing.
For military and marine applications we need special type of monitors for night time operations. It may not be possible to use the regular monitors that are not compatible with night vision equipment. During night operations where NVIS is used we need special night vision LCD monitors that can be dimmed so that it does not affect the functioning of the NVIS equipment. NVIS refers to Night Vision Imaging System and this is used for surveillance and other purposes where there is very little or absolutely no light around the object of surveillance. NVIS boosts photons from the night scene to about 2000 times. When NVIS goggles are used the environment in which the one using it should also be without any light or absolutely low levels of light. If the luminescence level is high then it will affect the NVIS badly and the vision of the one who is using it.
ECDIS refers to Electronic Chart Display and Information system and this is an electronic system that is used in ships and marine vessels to help them in their navigation. ECDIS will be able to integrate navigational position and ship sensor ENCs or electronic navigational charts. From 1995 this electronic format is accepted as equivalent to paper chart by International Maritime Organization. Paper chart is replaced by this electronic chart in all marine vessels.

ECDIS can reduce marine accidents that normally result out of human mistakes that happen due to fatigue and work load. ECDIS is an automated system and does not depend on the alertness of the mariners. Moreover, with this navigational tool it is possible to get 24 hour positioning of the marine vessels. ECDIS saves the mariners from endless chart work giving them more time to handle the problems better.
One of the biggest challenges of marine computing and marine display solutions is handling moisture and water. It is absolutely impossible to keep away water and moisture in marine environment so the monitor should be carefully engineered so that water and moisture do not cause damage to the display. Regular sealing may not be all that effective because moisture will be inhaled by the monitors giving a foggy appearance to the display.

It is not only the display screen that gets affected, even the hardware in the display will be damaged if water seeps in. Moreover if water seeps into the monitor, it may lead to short-circuiting leading to fire accidents. So it is a very crucial challenge for marine display engineering.

It is not all that easy to find the right marine display manufacturers because of all the issues discussed above. Though there are many companies that manufacture marine displays, all of them are not reliable products. Moreover, we cannot take risks in this area so all equipment should be selected with utmost care. While selecting your waterproof monitors look for companies that have been in this field for a long time and only select those companies that enjoy good reputation. Look for certifications that they hold and whether all their products are compliant with marine specifications.
Rugged monitors are used in industrial and military environments. We cannot use the regular LCD monitors that we normally use for our computers, laptops or television displays for industrial and military use because they are too delicate to survive the harsh conditions that prevail in military and industrial environment. However, computing has become an integral part of military operations and industrial requirements. In order to meet these special requirements there are specially designed monitors called rugged monitors. As the name suggests rugged monitors are hardy products that are meant to survive harsh conditions.

Designing monitors for such requirements presents a great challenge in terms of hardware requirements and design specifications. One of the factors that has to be endured by rugged monitors is the extreme temperatures. Both processors and monitors have to work properly in very hot conditions as well very cold temperatures. For example, operations that are deployed in desserts the temperature will go very high during the day and during the night it will go to the other extreme and get very cold. So, rugged monitors should withstand such a high fluctuation in the temperature.
Computers have invaded all aspects of our life right from infant food production to military operations. There is no industry today which does not make use of computers in one form or the other. The same applies to marine operations too; however when it comes to marine computing the computers should be specially designed to meet the harsh marine environment and they should be far more reliable than our regular computers because in computerized marine systems, life of people will be at stake if there is going to be any malfunction in the system. We cannot afford to have problems in marine computers and they should be 100% reliable. However, there are too many factors that affect the performance of marine computers from minor malfunction to complete crash of the system.
NVIS stands for Night Vision Imaging System. The NVIS converts photons from the outside night scene to about 2000 times. These days NVIS compatible LCD monitors are available for night operation at low backlight levels. We need NVIS compatibility in military environments especially for aircraft and marine use. Night vision compatibility demands that the intensity of emission from a color display be regulated within the range of 450 nm to 930 nm and particularly between 630 nm and 930 nm during nighttime operation. NVIS compatible LCDs are also capable of handling widest color range possible in ordinary daylight operation. To view the color active matrix a backlight is essential for illumination. For avionic and marine requirements extremely high intensity illumination is required during day time and low intensity illumination is required for nighttime mode.
LCD stands for Liquid Crystal Display. Liquid Crystal Displays that are used for industrial purpose are often rugged monitors that can withstand the wear and tear of the industrial use. Mostly, industrial lcd monitors will be used with industrial computers as a computer peripheral. Besides that industrial lcd monitors are also used as independent display units for displaying video images that are received from various sources such as surveillance cameras. These days LCD displays are preferred over CRT monitors because industrial lcd monitors occupy less space when compared to CRT monitors. Moreover, the power consumption of LCD monitors is much lower than the traditional CRT monitors which were once used for industrial purposes. By using an LCD monitor you can save from 80% to 90% of the space that would be used by a CRT monitor and at least 50% on the electricity bills. Moreover, LCD monitors cause less damage to the eyes even when we watch video images for long hours.

The only difference between the ordinary LCD monitor and the industrial lcd monitor is the external casing. The industrial lcd monitor comes with a rugged or tough casing for increased durability. They often come in steel or aluminum frame so that it can be fixed easily on an equipment rack.
All of us know that LCD displays are used as monitors for desktop computers and laptops but there are other areas where LCD monitors are used. They are used for industrial and military purposes as well. When they are put to industrial and military use they need to have specially designed LCD monitors that will be able to withstand the harsh environments and rugged military application. Military LCD monitors should be highly durable and they cannot be expected to be handled gently like the LCD monitors that we use for domestic purposes. It should be possible to mount them in vehicles without being anxious about heavy vibration and shock. Military LCD monitors should function properly even when vehicles are driven on rugged terrains. The chassis of the military LCD monitor should be made of some strong material such as heavy steel or aluminum without making the monitor bulky or heavy.
Originally when computers were invented they were strictly limited to indoor usage and they were used only in air-conditioned rooms so as to maintain optimum temperature for the processor. Now it is not the case anymore, computing is no more limited to indoor use and everyday more and more new needs are realized that require us to use our computer in outdoor environments. There are many industrial situations which demand outdoor computing and if we do not have the right equipment at hand then outdoor computing can become a real difficult task. One of the delimiting factors of outdoor computing is bright sunlight and this makes ordinary LCD monitors almost useless. We need special sunlight readable displays so that we can still read the monitor without straining our eyes or without too much of glare. Sunlight readable displays come equipped with necessary technology to produce clear images that can be easily viewed even in bright outdoor environments. These sunlight readable displays use latest optical technology to create bright output.
LCD monitors which are commonly used by most of us as computer peripheral equipment, laptop monitor or as television display is extensively used in various other sectors. They not only serve as computer display unit but they also serve as a display unit in various other situations receiving inputs from a variety of sources including surveillance cameras. If we have to list all the areas where industrial displays are used, we will be surprised to see a large list. These industrial display units are very different from the display units that we use for domestic purposes.

Industrial display units are also called as rugged displays or rugged monitors because of the nature of their design and their use. These displays have to endure high level of wear and tear. Industrial display units accept input from various image sources and hence they are used for a variety of purposes. Originally, all industrial displays were traditional CRT monitors and with the advent of LCD monitors, CRT displays lost their market. Soon CRT monitors will become an obsolete product at least with respect to industrial usage. There are many reasons why LCD monitors are preferred to CRT display units for both domestic and industrial environments. One of the major problems of CRT displays is its size. It is too bulky and if we have bigger display requirements then the size of the entire unit becomes too big and they occupy a lot of space whereas, LCD displays are slim and they do not occupy a lot of space. It is possible to get large LCD displays without increasing the bulkiness of the unit.
It is not all that easy to design LCD displays for military environment because there are number of challenges involved in coming up with highly reliable displays. Designing LCD displays for military requirements is just not about providing good mounting systems and hard chassis. These are just some of the aspects of good Military LCD displays but there are other crucial factors involved. We cannot use all LCD displays for military purposes they have to meet stringent military specifications.

Military LCD displays should be able to endure extreme weather conditions and they should be able to function in both hot and cold weather conditions. One of the problems with regular LCD monitors is that in low operating temperatures their performance generally degrades and their response rate reduces at low operating temperatures. This is not the only problem or challenge, there are other factors those have to be dealt with; high temperatures too can be equally challenging.
COTS stands for ‘commercial off the shelf’ and COTS products are readymade products that are available for sale which can be readily used without any further need for alteration or customization. These are ideal for military and marine applications where the products have to meet strict product specifications.
IMO stands for International Maritime Organization and it is responsible for international maritime safety and safety practices. All equipment used in marine vessels should be IMO compliant. Marine environment always poses great insecurity and threat; to reduce the level of threat and to increase the safety of merchant vessels and naval vessels, people and goods that are transported, IMO has stringent specifications for all the gadgets used for marine needs. The same applies for display units or monitors that are used for marine applications.

We cannot use our regular LCD or CRT monitors for marine purposes because they will be exposed to harsh conditions in marine environment. Only IMO monitors will be able to survive the extreme conditions. If a monitor that is not compliant with IMO standards is used, it may still work but it may not be reliable and the performance level too would be affected drastically.
Today LCD displays are replacing the CRT monitors very rapidly because LCD monitors come with a number of advantages that cannot be seen in CRT monitors. LCD displays are encroaching all aspects of our life as their use has gone far beyond entertainment and office computing purposes. LCD displays are not only seen in domestic environment, they are also seen in commercial environments. Commercial LCD displays are very different from LCD displays that are designed for domestic purposes as commercial displays are used in a variety of harsh environments so the commercial LCD displays should be rugged enough to withstand the extreme conditions.

One of the main challenges that had to be faced by commercial LCD displays is the dust factor; in domestic environments the LCD displays will be subjected only to limited level of pollution and dust, whereas in the commercial environments there is no way we can keep the dust levels low. Complete sealing of the LCD display may also result in accumulation of heat so the challenge lies in designing a suitable chassis that will protect the commercial LCD display from excessive dust and at the same time will not lead to excessive accumulation of heat.
