Liquid crystal display in which data values are adjusted for cross-talk

Abstract

An active matrix liquid crystal display device having a row and column array of picture elements which each include a switching device and which are driven by a drive circuit via sets of row and column address conductors to which selection and data signals are applied respectively, includes a data signal adjustment circuit which adjusts a data signal intended for a picture element prior to its application to the column conductor and according to a compensation value derived from the values of data signals intended for other picture elements using the same column conductor in the period until the picture element is next addressed so as to compensate for the subsequent effects of vertical cross-talk due to capacitive coupling effects at the picture element. In determining the compensating adjustment, blanking intervals in an applied video signal and current leakage effects can also be taken into account.
