ABSTRACT:
A method and an apparatus reduce cross talk effects in electro-optical addressing structures. In a preferred embodiment, a flat panel liquid crystal display system (10) includes a layer (28) of frequency-sensitive liquid crystal material having a dielectric anisotropy that approaches zero for signal frequencies greater than a characteristic threshold frequency f.sub.th. The frequency-sensitive liquid crystal material is nonresponsive to components of signals with frequencies greater than the threshold frequency f.sub.th. A data driver (32) delivers inverted data signals (62) and conventional, noninverted data signals (64) to each of the multiple display elements (16) during successive first and second time intervals, respectively. As a result, the data driver generates cross talk having frequency components greater than the characteristic threshold frequency f.sub.th of the liquid crystal material. The liquid crystal material is not responsive to the high frequency cross talk, thereby substantially eliminating the cross talk effects.
