I recently found this thing
a lcd display from an old tensiometer.
It's nice an I wondered how could I hack it, since I have no datasheet and since the cables are really small:
and very hard to solder.
Could anyone help with this?
Unless you want to go through the really slow and painful process of reverse engineering every little detail, you'll need to find some datasheet on the driver ICs.
Flip the LCD panel over and look for part number on the back. Hunt for anything on the internet that relates to people using the same parts.Have a good hard look at the pins on that ribbon conected - many may not even be used.Try to determine the signals on each pin by checking them with a multimeter (or better yet an oscilloscope) while the unit is powered.
