Character LCDs / NHD-0216K1Z-FL-YBW grounding pad
« on: October 06, 2016, 10:19:45 AM »
Hello,
I'm using one of your LCDs on a new design,Part Number NHD-0216K1Z-FL-YBW.

In this particular design, i need to avoid ground loops through the mounting holes, i have seen that this PN has a copper trace that goes from one mounting hole pad to another pad labeled as "JFL"
on the back side of lcd, inside a silkscreen box labeled "K3", this box contains another pad labeled "JF" too.

I think these pads lets you select between connect the display metal frame to the physical ground(mounting hole pad) and the display's reference ground(PIN1 on CON1).

Could you please confirm that i had to cut this copper trace to effectively isolate display from ground?

Do you have any information regarding the "JFL" & "JF" pads and what functionality do they offer?

Best Regards
Jesus
