An active matrix display device having an array of LC picture elements (12), with associated switching means (25), addressed in row sequential fashion via sets of row and column address lines (14, 16) includes in its drive circuit a data signal adjustment circuit (40) which adjusts data signals before application to the column lines (16) so as to compensate for anticipated effects of vertical and lateral forms of cross-talk due to stray capacitive couplings in the picture element array. A correction value for a picture element data signal is derived in the adjustment circuit (40) according to the values of data signals intended over a subsequent field period for other picture elements in the same column and one or both adjacent columns, and the relevant capacitive coupling factors. The display device may be of the type using TFTs, TFDs or a plasma-addressed display device. |
