Cevians, once again, pushes the boundaries of NVIS technology. Leveraging a breakthrough from the Cevians Optical Products division, we are now offering NVIS compliant AMLCD cells. Using our VKK technology, Cevians offers near-infrared absorbing AMLCD glass in a flat format with display interface electronics or as a completed display module. Cevians latest VKK technology is based on a novel combination of complex thin film deposition and molecular photochemistry, the result of years of research and development. U.S. Patent office granted Cevians protection under patent 9927562 for this revolutionary innovation.

The VKK NVIS compatible AMLCD filters the infrared energy emitted from the display backlight while allowing high visible light transmission, above 65% of a non-NVIS TFT panel. The technology also eliminates AMLCD chromaticity shift typically observed in NVIS compatible display assemblies. A typical NVIS display will exhibit off-angle color shift from nominal to 45 degrees while the VKK AMLCD glass will maintain its chromaticity. The AMLCD cell thickness varies from 1.4mm to 1.8mm depending on the selected TFT technology. The color gamut can be tuned to satisfy the application requirement and be optimized to efficiently use the chromaticity characteristics of the backlight.

As a result of integrating the VKK technology in the glass cell; the display module designer can reduce the number of components, simplify the assembly process, optimize light distribution in the light-guide, and be guaranteed the display module will meet MIL-STD-3009 for NIVS compliance. Potentially the most significant benefit is the lower total cost of ownership compared with competitive design strategies. Early benchmarking indicates a cost savings ranging from 10%-25% compared with current technical solutions based on single or dual NVIS compatible backlight. In addition to reduced product cost, the display module designer will benefit from reduced lead-times and reduced non-recurring expenses.
