  • Greyscale of ferroelectric LCD via partial pixel switching and various bipolar data waveforms
    Patent number: 5793347
    Abstract: A method of addressing FLCDs produces one or more gray levels by switching part of the pixel. This is achieved by applying a waveform which changes between a voltage level which switches the entire pixel and a voltage level which does not switch any part of the pixel, such that the data signal requires only two voltage levels.
