New Liquid Crystals for Light Guiding Application: From Automotive Headlights to Adaptive Indoor Lighting

摘要

Recently, there has been a renewed interest in using liquid crystal devices for lighting applications. The applications include car headlamps as well as indoor architectural lighting. In this paper we will present the status of liquid crystal mixtures that are suitable for these applications. or automotive applications, the properties of the liquid crystal mixtures are expected to include robustness towards extreme environmental conditions as well as robustness towards extreme light load. For architectural application, the liquid crystals mixtures are expected to have the highest possible birefringence whilst still having good light stability.
