Depending on the temperature and particular nature of a substance, liquid crystals can be in one of several distinct phases (see below). In this article, we will discuss liquid crystals in the <B>nematic phase</B>, the liquid crystals that make LCDs possible. </FONT>
<P>One feature of liquid crystals is that they're affected by <B>electric current</B>. A particular sort of nematic liquid crystal, called <B>twisted nematics</B> (TN), is naturally twisted. Applying an electric current to these liquid crystals will untwist them to varying degrees, depending on the current's voltage. LCDs use these liquid crystals because they react predictably to electric current in such a way as to control <A href="http://electronics.howstuffworks.com/light.htm">light</A> passage. </P>
