Liquid Crystal Technology
 |
The
most common LC application is in information displays.
|
|
The
first LCD was developed in 1968 at RCA Laboratories, but it required
high
voltage and consumed too much power.
|
|
First-generation
LCDs were used primarily in small alphanumeric displays such
as wristwatches, calculators, and car dashboards.
|
|
Current
LCD applications include
laptop computer screens, flat-panel displays,
projection, and
large-screen displays.
|
|
Nondisplay
applications include switchable windows, color filters, thermometers,
temperature sensing films, tumor testing, optical beam steering,
optical
waveguides, and telecommunications.
|
Some of the main advantages
that liquid crystal technology offers are lack of moving parts,
temperature independence, proven manufacturing process, long lifetime,
quick response time,
and low cost of ownership.
