Hacking a kitchen timer LCD

Thank you all for the responses. I have a ton of these laying around so I think I'm going to try to get them to work instead of buying something. I couldn't find a data sheet for my display, but I found that the operating voltage is usually no greater than 5v ac. To test this out and determine pins, should I build an inverter circuit?
And then get a driver, I assume, to use when interfacing with Arduino.
