http://www.tvrepairinfo.com/ In this video I dissected an LCD panel to see
what it looked like under a microscope. It's hard to believe a technology
so small can actually work.

Liquid crystal displays (LCDs) consist of liquid crystals that are
activated by electric current. They are used most frequently to display one
or more lines of alpha-numeric information in a variety of devices: fax
machines, laptop computer screens, answering machine call counters,
scientific instruments, portable * compact disc players, * clocks, and so
forth. The most expensive and advanced type—active matrix displays—are
even being used as screens for handheld color TVs. Eventually, they may be
widely used for large screen, high-definition TVs.

The basis of LCD technology is the liquid crystal, a substance made of
complicated molecules. Like water, liquid crystals are solid at low
temperatures. Also like water, they melt as you heat them. But when ice
melts, it changes into a clear, easily flowing liquid. Liquid crystals,
however, change into a cloudy liquid very different from liquids like
water, alcohol, or * cooking oil. * At slightly higher temperatures, the
cloudiness disappears, and they look much like any other liquid.

When the liquid crystal is a solid, its molecules are lined up parallel to
one another. In the intermediate cloudy phase (liquid), the molecules still
retain this more or less parallel orientation. As in any liquid, the
molecules are free to move around, but they tend to "line up" in one
direction, reflecting light and causing a cloudy appearance. Higher
temperatures tend to agitate the molecules and thus make the liquid clear.

In an LCD, an electric current is used to switch segments of
