Notes on Etching:
What type of patterns donít work?
The pattern to the right represents an
etched ITO pattern on glass.
parts are where ITO is present.
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
This section of ITO lacks current.
