Analogue-sequencer

I managed to find a blue display (better then what i found yesterday)
locally that seemed to fit the bill, it is a winstar WH1602A-TMI-JT 

Once i got it i realised it has a negative voltage generator onboard?
I asked the guy i bought them off about it and he replied :

"3V Power Supply means as the LCD generates Negative Voltage, it can
also run in 3V power supply.

You can use the 5.0V power supply follow the spec sheet as well. The
only difference is to connect the backlight, instead of using pin 15
and 16, u have to connect A&K Pin to get the backlight as Pin 15 and
16 will perform as a negative voltage generator.

All the others connections will remain the same."

I'm a little confused here and was hoping someone might help, can i
wire this the same as the standard display colin supplied? Can i do
any damage to the P3 by using one of these?

I have boring old green lcd's that will be fine but would love to use
this blue one tonight if i can.

thanks
Brett
