An electronically controlled Variable Transmittance Visor (VTV) will permit a pilot to use a Helmet Mounted Display (HMD) system at maximum effectiveness in all lighting conditions without having to add or remove fixed-tint visors. This project will investigate the material and process advancements necessary to adapt AlphaMicron's patented VALiD guest-host liquid crystal technology and its patented thermoforming system to the fabrication of a large area, double-curved liquid crystal device employing flexible plastic substrates. A key issue will be the development of a transparent conductive material which is compatible with the significant deformations necessary to successfully thermoform a liquid crystal device to conform to the Air Force's HGU-55/P visor.
