Notes on Etching:
What type of patterns don’t work?
·
The pattern to the right represents an
etched ITO pattern on glass.
The black
parts are where ITO is present.
(positive resist)
·
·
The ITO connects to a power source
that makes contact along the right edge
of the display (the red bar).
·
The phosphor under the ITO electrode will only be excited if the ITO
has current running through it.
-
Notice that the ITO inside the capital "D" is not connected to the rest of
the ITO.
-
This section of ITO lacks current.
