摘要
The method involves providing a first time period for application of an electrical signal for selecting one of two states, and a second time period for holding the selected state, either without application of the electrical signal, or with the application of an electrical signal for selection of none of the states using the memory characteristic of the ferroelectric liquid crystal or antiferroelectric liquid crystal during a common pixel selection period. The electric signal for selecting one of the two states is a pulse signal of positive polarity w.r.t. a reference level. The electric signal for selecting the other of the states is of negative polarity. A spatial light modulator and a method of driving a spatial light modulator are also claimed.
