1.1 Properties of Liquid Crystals
Liquid Crystals exist in an unusual state that is somewhat like a liquid and a solid. The
molecules in this state tend to maintain their orientation like molecules in a solid but also
move around to a different position like a liquid. There are several distinct phases of
liquid crystals, dependent upon how they are used.
A twisted nematic (TN) LC display consists of two polarizing filters, two pieces of glass,
some form of switching element or electrode, which is connected to a power source as
depicted in Figure 1. An applied voltage is used to untwist one pixel.
