Hi all.
I hear you need to apply a square wave when using a lcd display.
Im using a 4543 type chip.
Question is, do I need to apply and square wave to the
4543
the back plane of the lcd ( common/gnd )
or both
if both does the square wave need to be in sync or opposing/inverted to each other.
Cheers.
