I happen to have a EM32100 LCD Display laying around from an old telephone and would like to make it show digits with the Arduino. Well i managed to change between the clock and stopwatch and set the clock. However this is fairly easy to do. The link below is the documentation of the display, but i can't figure out where the latch pin is (if any). There is a Serial data input pin for sending bytes and making some tests unfortunately i haven't manage to display anything. If someone could point out where the necessary pins are, and how i can shift them (probably with shiftOut, since i saw some the examples from the Arduino learning).
