I use to run EL backlight from 220V 50Hz with only a 300k to 500k resistor in se
ries.

Has anybody got an easy to implement circuit to power an lcd EL backlight?
I guess I need about 110V at around 400 Hertz.  Too slow a frequency to use
a PIC pin to drive an oscillator, and too much increase for a charge pump
circuit...want to avoid special DC-DC converters and such, and the available
little pcb inverters are really expensive, if you can find them.
Any suggestions??
Thanks
