ABSTRACT:
A method and an apparatus for addressing a liquid crystal display (10) groups together row electrodes (28) and applies the same row addressing signal to all row electrodes in the group (48). The groupings are cyclically changed in successive addressing cycles. An image data conditioner (54) determines for use in calculating the column signals a pixel information value based upon the information values of one or more of the pixels in the selected group of row. Grouping the row electrodes reduces the effective multiplex ratio, thereby increasing the selection ratio and producing a faster responding display having higher contrast and a wider viewing angle.
