Well 300 Hz should be just about enough.
To get you started you can buy ready made inverters for these things (TDK
in Japan makes them) or contact Sipex; they make ICs dedicated to these
applications. Actual diagram and component value may change according to
type of EL film, but it should be OK for one off; it would be a different
matter if you want to start mass production. There tuning of EL lamp and
inverter becomes critical for long life of the lamp. Durel and Seiko
Precision also carry EL lamps and drivers, Supertex also makes ICs for
drivers.
I wish you successful experiments; let us know.
