Abstract
As the battlefield becomes "digitized", all arms of the military are deploying COTS displays in the form of Portable Notebooks, Kneeboards, GPS and PDA's in ever greater numbers. Many of these COTS equipments and associated displays use full color LCD's and resistive touch panels as the operator-interface. These displays are a challenge to those who must modify the COTS equipment for NVG compatibility. Traditional NVG filter options have relatively poor color rendering and are too thick or rigid to interface with touch panels. In addition, many of these displays do not have sufficient dimming capabilities to allow covert night-time operations and do not have sufficient luminance for daytime operations. Polymeric materials recently developed by Wamco have been specifically designed for applications where traditional NVG filters have failed. These applications will be discussed and quantified in terms of NVG Compatibility, Color Rendering, Luminance Contrast and Daytime Readability, Touch Screen Sensitivity and Environmental Performance.
