Glare Reducing Windscreen Using Principle of Selective Reflection

Abstract

Automobiles are prone to accidents due to glare effect at night. The scope of this research is to reduce the glare. Theconcept of Electrochromic glass was used. A windscreen was made up of a pair of float glass enclosed with Twisted Nematic Liquid Crystals. The liquid crystal material exhibited a property of selective reflection of incident light. A liquid crystal material E48 was used for this purpose and the results were studied. The wavelength of light within a narrow range which caused glare was selectively reflected. This resulted in reduced intensity of glare thus protecting the driver from glare during night travel.
