  • Liquid crystal lenses having attenuated switching noise
    Patent number: 8648899
    Abstract: The invention relates to liquid crystal lenses having dynamically switchable light transmission, including: a shutter (2) including two transparent substrates (21, 22) and a nematic liquid crystal layer (20) arranged between the substrates (21, 22); and a control circuit capable of alternately applying a bias voltage or a relaxation voltage across the liquid crystal to render the shutter (2)clear or opaque, the falling edges between the bias voltage and the relaxation voltage having a duration of 80 to 900 ?s.
    Type: Grant
    Filed: October 7, 2010
    Date of Patent: February 11, 2014
    Assignee: Volfoni R&D
