FAST, HIGH-CONTRAST FERROELECTRIC LIQUID-CRYSTAL DISPLAYS AND THE ROLE OF DIELECTRIC BIAXIALITY

The operation of ferroelectric liquid crystal displays depends strongl y on the material properties and the electrical addressing method. Fas t, high-contrast displays with high levels of multiplexing and wide op erating ranges are possible using materials showing a minimum in their response time-voltage characteristic operated with JOERS/Alvey and re lated drive schemes. These utilize materials with significant dielectr ic biaxialities and relatively low values of the ferroelectric polariz ation so that a minimum is observed in the switching characteristic. T he route for material improvement is explored.
