100 Ohms to 220 Ohms  series & 4k7 to 22K  parallel at pin (pull to 0V=20
or VCC depending on which =3D inactive).
Or maybe 220 Ohms at CPU pin end  and 220 Ohm at LCD pin end and 4k7 to=20
22K  parallel at LCD pin

For reducing RFI creation and susceptibility  it's common do this, esp=20
if the display isn't very close to CPU pins.

You can do it just enable line or on all pins to reduce RFI in and out.
