Abstract

A display device (1) comprises a matrix of selectively settable liquid crystal display cells defined by areas of overlap between members (5-13) of a set of row electrodes and members (2-4) of a set of column electrodes. A first column electrode (2, 3, 4) comprises a plurality of first column portions (a, b, c; A, B, C), each defining a sub-matrix (14, 15, 16). The display device (1) further comprises means (not shown) for driving said first column electrode; selectively operable means (17-22; 40-48) for switching for permitting selective electrical connection from each first column portion to the driving means and means (not shown) for addressing simultaneously rows in more than one sub-matrix.
