Abstract
A method of driving a liquid crystal display (LCD). The LCD employs a phase transition liquid crystal. An AC waveform drives the liquid crystal. Pauses, which represent periods in which zero volts are applied to the LCD, are inserted into the AC waveform to attenuate the internal electric fields produced by the electric field reactions of molecules in the phase transition liquid crystal. This method allows thin film transistors to drive the phase transition liquid crystal, thus realizing a projection LCD that employs no polarizing film and is bright and stable.
