Methode zur Darstellung von Grauwerten auf einer ferroelektrischen Flüssigkristallzelle mit variabler Dicke
A ferroelectric liquid crystal cell is controlled by applying a strobe pulse (Vs) and a data pulse (Vd1, Vd2, Vd3) to the cell, the magnitude of the data pulse being modulated in order to control the resultant pulse applied to the cell. The resultant pulse comprises a pre-pulse on one polarity and a...

| description | A ferroelectric liquid crystal cell is controlled by applying a strobe pulse (Vs) and a data pulse (Vd1, Vd2, Vd3) to the cell, the magnitude of the data pulse being modulated in order to control the resultant pulse applied to the cell. The resultant pulse comprises a pre-pulse on one polarity and a main pulse of the opposite polarity. When applied to a liquid crystal cell of stepped thickness, the application of data pulses of different magnitudes switches regions of different thicknesses of the cell so as to provide grey level capability. |
