  • System and methods for using modified driving waveforms to inhibit acoustic noise during driving of a liquid crystal polarization rotator
    Patent number: 9958695
    Abstract: In some embodiments, a system and/or method may operate a liquid crystal device. The method may include increasing a voltage provided to a driven level to a liquid crystal addressable element of the liquid crystal device. Said increasing may be performed over a time period greater than 1 ms. The liquid crystal addressable element may be in a driven state at the driven level. The method may include reducing the provided voltage to a relaxed level. The liquid crystal addressable element may be in a relaxed state at the relaxed level. Said increasing the voltage over the time period to the driven level may result in a reduced acoustical noise associated with the provided voltage. In some embodiments, the liquid crystal device may include a three-dimensional (3D) display.
