Abstract
A driving apparatus for a liquid crystal display of a type sandwiching a layer of liquid crystal material capable of responding to a voltage of an effective value applied between row and column electrodes. The apparatus includes an image data buffer memory for storing and outputting a digital image data of one frame, transferred from an external circuit, in the form of an image data matrix; a matrix generator for outputting data having a predetermined orthogonal matrix; a converter for converting the image data with the use of the orthogonal matrix into an converted data matrix and for outputting the converted data matrix; a converted data buffer memory for storing and outputting the converted data matrix; a driver for driving the liquid crystal display in synchronism with a row signal, which applies the orthogonal matrix to the row electrodes of the liquid crystal display, and also a column signal which applies the converted data matrix to the column electrodes of the liquid crystal display.
