NVIS LCD DISPLAYS

NVIS LCD DISPLAYS
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.

    • Nauticomp, which is one of the leading display manufacturers produces NVIS compatible LCD monitors that can be used in military environments for nighttime operations. Named as Glass Bridge Displays the NVIS compatible monitors use an advanced technique which dynamically adjusts the brightness permitting the full brightness to be dimmed at nighttime with low backlight levels.

    Glass Bridge Displays are one of the largest displays in the market with the smallest housing possible. These displays come in a series of display sizes starting from 12.1” to 21.3”. This display will work with almost ten types of inputs including S-Video, standard PC graphics cards, Component and Composite Video sources. It can also process low resolution VGA signals.     		There are number of techniques available to make the LCD monitors NVIS compatible but the advanced technique used by GB is the most effective technique. It provides a seamless transition between daytime and nighttime operations when compared with other systems. Nauticomp NVIS LCD monitors can reduce the illumination to 2cd/m2 (approx) for night use. The NVIS LCD monitor allows the user to use night vision goggles which are highly sensitive to light especially in the red spectrum that is closer to infrared. In order to safeguard the vision of the user who uses night vision image goggles NVIS compatible displays can be dimmed to red. If the internal light field is not compatible with the night vision imaging goggles then it can reduce the performance for the goggles. Normally the LCD monitors become a problem because they emit light that is not compatible with the night vision goggle. This is where the importance of NVIS LCD monitors come into play. The advanced brightness dimming technique used by Nauticomp’s Glass Bridge Displays solve the problem effectively.
    This NVIS LCD monitor has an effective On Screen Display user interface called GB Commander. With the GB Commander it is possible to adjust a number of display parameters as and when required. The settings can be stored in EEPROM so it is retained even after the power is switched off. We can connect up to 10 GB displays through USB cables and the backlight brightness level can be controlled with a single GB commander. Nauticomp NVIS LCD monitors are manufactured as per ISO standards. Visit HYPERLINK "http://www.nauticomp.com" www.nauticomp.com to know more about this NVIS LCD monitor.
