  • Fast-acting low voltage liquid crystal stereo glasses
    Patent number: 9532037
    Abstract: The invention relates to the field of optoelectronics and display technology and can be used in high speed stereoscopic glasses when working with any type of 3D display, designed to operate with active stereo glasses with standard (60-160 Hz), high (hundreds of Hz) and ultrahigh (several kilohertz) frame rate. According to the invention in optical shutters of high-speed stereo glasses a layer of the helix-free ferroelectric liquid crystal (FLC) with optimized physical parameters is used. The technical result is an increase of the optical contrast of FLC shutters, reducing the amplitude of the control voltage.
