The method improves the contrast of the ferroelectric LCD. When the voltage levels are in -V<-V2<-V1<0<V1<V2<V and the first state of the data is to be displayed, the voltage levels are changed in sequence of -V,-V2,V2,V and applied to the LCD while the scanning signal is applied, but the alternative voltage of -V1,V1 in the rest time. When the second state of the data is to be displayed, the voltage levels changed in sequence of V,V2,-V2,-V are applied to the IC while scanning signal is applied, but the alternative one of -V1,V1 in the rest period.
