Seems not. Vcc - Vee spec =3D 15.0V typical. Experiences of others
using this panel is that -10V or close to it gives best contrast

I'll be writing s/w for the 18F2520 driver tomorrow so I'll soon find
out. Maybe their contrast isn't to my liking

Whilst I develop I can for at least a time use the adjustable -10V of
the SMPS IC but I really would like then to explore alternatives. I'm
sure I have a Microchip AN about switchmodes around here
