Liquid Quartz Display?


#1
    Remember that some people are looking at LCD monitors Liquid
Quartz Display OK! Now all this stuff happening on that screen is
set in motion by very minute electrical impulses working on the
Liquid Quartz(there is that word again) sandwiched in some
thermoplastic cover with little wires in a bunch of different
places. 

Hi all, This post was originally under the Universal Interfaith
Symbol thread which already has proven to be Universally
Disagreed-Upon, so I’ve decided to post this reply under a new
thread, also because it needs it’s own.

Although my degree is in gemology, I spent around 20 years as an
electronic technician, and have been involved with computers as a
hobby long enough to have an honorary PhD in Computer Geek. Someone
recently posted that they’d been an internet contributor since the
days of CompuServ before this “new-fangled thing called The
Internet”. The truth is that the Internet was around before
CompuServ or Prodigy, designed and utilized by the US military long
before those other two services became available. But, I digress…

Actually, LCD is an acronym for Liquid Crystal Display, not Liquid
Quartz Display. In fact, there is no quartz involved in the
manufacture of LCDs. The types of liquid crystals are a subject of
some depth that would require far too much discussion and most of us
who subscribe to this forum probably couldn’t care less, but here is
a short list: super twisted nematics (STN), dual scan twisted
nematics (DSTN), ferroelectric liquid crystal (FLC) and surface
stabilized ferroelectric liquid crystal (SSFLC).

Perhaps the closest that an LCD-type display comes to having quartz
as a component are the TFT (Thin Film Transistor) type of display
that many laptop computers use. It is composed of millions of tiny
PN junctions (diodes and transistors) usually made of doped silicon,
a part of the Silicon Dioxide we know as quartz.
