HIGH-SPEED LOW-VOLTAGE LIQUID CRYSTAL 3D GLASSES Russian patent published in 2014 - IPC G02F1/133 G02B27/22 

FIELD: physics, optics.

SUBSTANCE: invention relates to optoelectronics and display equipment and can be used in high-speed 3D glasses when operating with virtually any type of 3D display, designed to operate with active 3D glasses with standard (60-160 Hz) and high (hundreds of hertz) and ultra-high (up to several kilohertz) frame frequency. According to the invention, a layer of non-helicoidal ferroelectric liquid crystal with optimised physical parameters is used in optical shutters of high-speed liquid crystal 3D glasses.

EFFECT: high optical contrast of ferroelectric liquid crystal shutters, low amplitude of control voltage.
