Abstract:
An active matrix liquid crystal display device comprising: a row and column array of liquid crystal display elements, each display element having an associated switching device, sets of row and column address conductors connected to the display elements via which selection signals and data signals, respectively, are applied to the display elements, a row drive circuit for applying selection signals to the set of row address conductors and a column drive circuit for applying data signals to the set of column address conductors, which column drive circuit is operable to transfer the data signals for the display elements of a row to groups of column address conductors in sequence, in respective group address periods, each group comprising a plurality of column address conductors, characterized in that the column drive circuit is arranged to apply, during an address period for one group, a pre-charging signal to the adjacent column address conductor of the next-addressed group of a level dependent upon the level of a data signal for a column address conductor in that one group.
