PCT No. PCT/GB94/01503 Sec. 371 Date Mar. 14, 1996 Sec. 102(e) Date Mar. 14, 1996 PCT Filed Jul. 11, 1994 PCT Pub. No. WO95/02235 PCT Pub. Date Jan. 19, 1995In a three-slot addressing scheme for a liquid crystal optical modulator, where the data waveforms comprise a data section, a charge-balancing section and a further section, the form of the further section depends upon the sequence of data waveforms. The further section or pair of adjacent further sections comprises a pair of pulses of opposite polarities which charge-balance each other. The order in which these pulses occur in the pair enhances the effect of the adjacent data section to aid or inhibit switching as appropriate. This facilitates a shorter line address time.
