CFAG12864B V option LCD Bias Questions

I assume the V option will generate a negative voltage on Vee (pin 18). I cannot find in the datasheet the minimum and maximum values output on Vee. Anybody know?

I intend to do a form of temperature compensation as my application is a handheld that will see varying temperatures. Is it acceptable to pulse width modulate Vee into the Vo pin through a single pole LPF? Are there easier ways to compensate for the effects of temperature?

Thanks,
Dustin
