Hi All,

We are changing from std Yellow positve STN to Blue/White negative STN.

Does the contrast voltage pin work in opposite direction between postive
and negative STN?

Eg
For deeper contrast on positive STN : Contrast Voltage reduced
For deeper contrast on negative STN Contrast Voltage increased

Are these statements above correct?

Thanks in advance
Joe
