Summary: A place to get liquid crystal displays


A good place to get liquid crystal displays is from Hitachi or Sanyo 
(Hitachi is cheaper for the 24x1 display).  Both companies offer
a wide range of display sizes with both graphics and text.  I suggest
you order a catalog to get the right one.  I would also suggest that you
get the premade "Display Modules" which include both the display and the
LSI controller.  Generally the interface to the controller is a 4/8 bit
microprocessor compatible I/O interface, although serial interfaces are
also available.  The power supply required vary depending on size and
features, but mainly 5V is required.  Large displays (i.e. full screen) also
require either -12 or 20V supplies (depending on manufacturer).  All of these
the displays use the same controllers (made by Hitachi which probably 
explains why Hitachi is cheaper).


For more info. on Sanyo contact DeAngelo, Rothman & Co. Inc, (213) 827-2202.
For more info. on Hitachi contact Hitachi Electron Tube Division
(408) 435-8300.

There are other people who make these displays, including some American
manufacturers (although I'm not sure how much is actually made in the U.S.
since I noticed that many modules are IDENTICAL except for price)
