Abstract
A driving apparatus for driving a passive matrix liquid crystal display utilizing an active driving method includes an image buffer storage for storing one frame of image data in the form of a matrix to output image data on a column by column basis to produce a rearranged image data. A matrix generator generates row data. A data converter multiplies the rearranged image data with row vectors to produce converted data. A converted data buffer storage stores the converted data and outputs the data on a row by row basis to produce a column data. A LCD driver is provided for producing a column signal based on the column data and a row signal based on the row data, and further for applying these row and column signals to row and column electrodes, respectively, to drive the LCD.
