Character LCDs / Re: NHD-0216K1Z-FL-YBW grounding pad
« on: December 09, 2016, 04:41:17 PM »
I'm curious what the resolution here was. We use a different part (NHD-0420DZW-AB5), but it has similar connections and components. It appears JHG connects the display metal frame to the mounting hole chassis ground through a 0 Ohm resistor, and then JFG connects the chassis ground to the digital ground through a 100 kOhm resistor.

The same basic questions apply. Can JFG be eliminated or perhaps increased to a 1 MOhm resistor?

EDIT: Or, alternatively, can JHG be removed? Which would be most recommended?
