Gordon, I have used one of these beasties. It came from Densitron Corporation.
They sell 6 different types, which put out a range of 34-110 MA and 67-86
volts, some running at 410 HZ up to 750 HZ. I paid about 10.00 dollars for
mine, and it runs a backlight on a 2X40 character display. They also sell
displays. Anyway, to get more info on these, call Densitron. 
    By the way, they sent me a complete little folder showing all there
small lcd products, and application notes. I really liked the way all there
stuff works. Good luck!

    Densitron Corporation
    2540 West 237th ST.
    Torrence, CA. 90505 USA
    213-530-3530
 
    Part number that I am using is: das5v7 (5 volt input)

    satisfied customer. */
