Method of addressing a ferroelectric liquid crystal display screen with a chiral smectic phase.

摘要

Method of addressing a ferroelectric liquid crystal display screen with a chiral smectic phase comprising a cell enclosing the crystal, which cell is equipped on its walls with two matrix systems of line conductors and of column conductors, characterised in that the line signals VLi have an amplitude VL and a duration which are sufficient for the switching threshold (VT)threshold of the white state or of the black state to be exceeded for each pixel before the arrival of the active part of the write pulse VC.
