3. 2. Using micro - structures to couple light into thin light - guides

   University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)

   Author : Yun Chen; [2011]
   Keywords : ;

   Abstract : The task of this project is to investigate the possibilities of using micro-structuring on the surface of thin light-guides to efficiently couple light from top-emitting LEDs into such light-guides. Areas of application are backlighting for LCD TV and flexible light emitting layers for lighting purposes. READ MORE
