Liquid crystal display apparatus and driving method of such apparatus
摘要:
A liquid crystal display apparatus which has a display section in which a group of scan electrodes and a group of signal electrodes are arranged in a matrix shape and a ferroelectric liquid crystal having a bistability in the direction of an electric field is filled between both of said electrode groups and displays an image or information, comprising:
   means for sequentially writing gradation information from a pixel having a high threshold value on a scan line by a pulse to completely reset all of pixels on a selected scan electrode into a first stable state and one or a plurality of pulses subsequent to said reset pulse.
