Jeff’s quickie page of vintage and unusual LCD:

Liquid Crystal Displays

This is from a neighbor: it gives directions to nearest gas station, etc. BUT THE ROM DATABASE CANNOT BE UPDATED! Definitely surpassed by GPS now.
IF I want to re-use the 14 segment LCD, it looks *possible* since it's a ribbon cable. But is it soldered or glued?

Lots more to come!

LCD degradation

LCDs seem to fail when the liquid evaporates, usually starting at the edges.

	My drawer of vintage LCDs from 80s surplus catalogues I wonder if one going bad ruins the others
	The OP-1314 4 character 14 segment have both gone dark
	The SX179 6 digit 7 segment LCDs are darkening from the center
	The SX181 4 digit 7 segment LCDs are darkening from the center
