  • Patent number: 8325108
    Abstract: A system for controlling brightness flicker of a parallax barrier LCD having a wide viewing angle capable of minimizing brightness flicker by adjusting a permittivity curve depending on different times into a predetermined waveform when split barriers are on/off by movement of a viewer's viewing angle, and a method thereof. A method of controlling brightness flicker of a parallax barrier LCD having a wide viewing angle for controlling brightness of a display providing a stereoscopic image by acquiring a real-time image of a viewer, recognizing an image of the viewer and extracting locations and coordinates of eyes of the viewer, and controlling turn-on/off of split barrier electrodes.
