Abstract
A method and an apparatus for driving a passive liquid crystal display to obtain a high contrast ratio for both still image and video modes includes driving some or all of the row lines simultaneously. The row voltage wave forms are defined as a set of orthogonal functions and the column voltage wave forms are defined as a linear combination of the row voltages. The mean square voltage across each pixel and row is specified, and the corresponding column coefficient is calculated from which all coefficients in a column can be determined.
