ABSTRACT:
A nonlinear, two-terminal type, active matrix display device has a liquid crystal material sandwiched between intersecting row and column electrodes to define a matrix of picture elements. To avoid crosstalk, a non-selecting signal applied to a row electrode picture element is made equal in phase and amplitude to a signal fed to the opposed column electrode in order to reduce the effective voltage applied to the picture element during each non-selecting period to near zero.
