1. What method of voltage boosting are your using (inductive/capacitive) and to what voltage? Are you using charge pumps, capacitors, or inductors? If the screen has inductors, are they clamping? Can you provide an idea of the size/value of the inductance?
2. What is the lead spacing on the controller chip? Ideally, we want to know the minimum spacing for any trace/pin on the board. Do you seal the controller chip under the packaging?
