Ok, I give up. Google isn't being much help.
Anybody know how to drive a 7 segment LCD panel? No electronics, just the glass plate. (Yea, I know there's 2 plates and some goop and electrodes....)
I saw a page about driving the backplane with a 3state output and 2 resistors to get 3 levels and using a plain output to get 2 levels for the foreplane, but his timing diagrams weren't a lot of help knowing just how to disturb those little molecules.
BTW: Didn't it take a high voltage, like 21 volts to run these? It's been too long since I fiddled with one. AllElectronics has a cute panel for 25 cents if you buy in quantity 4. It seems to be 4 1/2 7 segment digits, 3 lines of writing on the lower left and some alpha characters in the lower right. There's pins on the terminals for connecting.
