Guest-host Liquid Crystal Dimmable Visor (GHLC-DV)

ABSTRACT:There is interest in developing an electronically controllable variable transmittance for fixed wing visor applications. Guest-host liquid crystal technology developed by AlphaMicron, namely e-Tint, has demonstrated the ability to meet the optical requirements for this application. However, implementation on large area, complex curve visors has not been attempted.AlphaMicron proposes to investigate the use of its e-Tint technology for variable transmittance visor application. The program will study the relevant parameters associated with fabrication of a doubly curved liquid crystal device using plastic substrates.BENEFIT:The program will identify the relevant parameters and potential limitations associated with implementation of guest-host liquid crystal systems for large area, complex curve eyewear including visors. Successful program will overcome issues associated with visibility of image in bright lighting conditions and will serve to enhance the performance of a pilot. Commercial applications for this development include fixed and rotary wing pilots as well as consumer motorcycle riders.
