ABSTRACT:
There are method and apparatus for driving a liquid crystal display apparatus which has a liquid crystal and electrodes arranged in a matrix form and in which a number of pixels having a memory effect are provided. Image information is displayed by a refresh scanning by using the liquid crystal display apparatus and is displayed by a non-refresh scanning without substantially changing the image information displayed by the liquid crystal display apparatus. A signal to fluctuate a transmission light amount of the pixel is applied to the electrode during the execution of the display by the non-refresh scanning. A smectic liquid crystal or a ferroelectric liquid crystal is used as a liquid crystal.
