Can you solder to heat seal cables? The ones I have seen are carbon traces, as opposed to the FFC which is a copper trace.

W.R.T. LCD damage. My line of thinking is that if a common row driver is disconnected the vertical drivers are still biasing the pixels. If each LCD segment is not equally biased (50% of time current flowing one direction, 50% other direction) it will fail fairly rapidly. It seems that pad damage on the glass is more likely though.

W.R.T. soldering FFC. Yes, you can only do this with copper. Not carbon printed ones.
